UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING 1 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING I. Occupational, Safety & Health-OSH Fundamentals II. OSH Legislation & Standards III. Site Safety Regulations & Framework At the end of this lecture material, it is expected that the students will be able to: I. express appreciation on OSH & recognize the importance of various data and legislation about OSH. II. recognize safety hazards and appropriate safety measures in a Construction Site. These objectives are adapted from the mandatory 8-hour safety and health seminar for workers under Section 16 of RA 11058 and section 3 of DO 198-18. 2 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Common terms & key descriptions o Accidents o Incident o Control o Hazards o Safety o Unsafe Acts o Unsafe Conditions Response to unwanted Conditions Management Safety Programs Safety Audit “Safety is not just signs and handrails, it is in people’s minds.” -Tony Smith , National Safety Council 2006, Turin, Italy For construction safety, it is imperative that we familiarize ourselves with the common terminologies used, They are detailed below: ACCIDENT -It is an undesired event that results in harm to people, damage to property or loss to process. It is usually a contact with a source of energy above the threshold limit of the body or structure INCIDENT-It is an undesired event which, under slightly different circumstances, could have resulted in harm to people, damage to property, or loss to process CONTROL- an action to regulate or restrain a condition or event. HAZARDS-Are unsafe practices or conditions, that if not controlled, may result into the occurrence of an accident or an incident RISK-Is chance of a physical or personal loss SAFETY-Is the control of hazards to attain an acceptable level of risk UNSAFE ACTS-Are behaviors which could permit the occurrence of an accident or incident Unsafe acts also represents the deviation from standard procedures or practices UNSAFE CONDITIONS, are circumstances which could permit the occurrence of an accident or incident. This also pertains to deviation from standard conditions regarding equipment, materials, or environment. 3 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING All work exposes workers to hazards ( especially for construction job-site): Manual handling of materials Use of machines Exposure to toxic substances Contact to electricity stress Main Definition: Occupational Safety and Health (OSH) “ state of being certain that exposure to workplace conditions will not cause adverse effects to the well- Source: Leigh, JP. (2001) being of a worker in terms of INJURY or ILLNESS” After reviewing common terminologies, we will briefly examine the implications and management of safety in construction workplaces. The images above effectively illustrate both the reasons and resolutions to safety and health programs in a job site. The intended focus of this discussion is further emphasized by the forward written by US-OSHA(2016): Establishing a safety and health program at your job site is one of the most effective ways of protecting your most valuable asset: your workers. Losing workers to injury or illness, even for a short time, can cause significant disruption and cost—to you as well as the workers and their families. It can also damage workplace morale, productivity, turnover, and reputation. 4 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING OSH is important based on three (3) arguments: 1. It is the right thing to do 2. It is the smart thing to do 3. It is the law (WHO, 2010) First Argument- based on ethical principle, employer has moral obligation -To protect employees from accidents & illnesses -workers have the right to safe & healthful workplace Second Argument-based on economic principle. -accidents impose a massive cost to business -lowers productivity and can even end a business Third Argument-it is the law -based on legal principle that violations causes penalties and work stoppages Occupational, safety & Health-OSH is important based on 3 arguments: 1) it is the right thing to do, 2) it is the smart thing to do, and 3) it is the law, according to the World Health Organization –WHO (WHO, 2010). The first argument, “right thing to do”, is based on ethical principle: that the employers, while earning a profit, have the moral obligation to protect employees from accidents and illnesses. It is expected that workers have the right to safe and healthful workplace. The second argument, ‘the smart thing to do,’ is based on the economic principle: no business owner wants accidents because accidents and illnesses impose a massive cost to business. Accidents not only lower productivity, but in the worst case, can even end the business. The third argument, ‘it is the law,’ is based on the legal principle that employers violating the provisions of the law are subjected to penalties and can be issued work stoppage orders by the appropriate authorities. 5 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Common terms & key descriptions o Management o Safety Programs o Safety Audit Source: Leigh, JP. (2001) Source: OSH (2016) As future practitioners, it is highly important to have an understanding of the frameworks and provisions for safety in the Construction setting. MANAGEMENT, is a special group of people whose job is to direct the effort and activities of other people toward common objectives SAFETY PROGRAMS, are activities designed to assist management and employees in the recognition, evaluation and control of workplace hazards. SAFETY AUDIT, Is the critical examination of the safety and health management programs to determine their effectiveness and compliance to regulatory programs. The hierarchy of Hazard Controls is also clearly illustrated above. Here, the elimination of a hazard is the most effective intervention compared to the last line of defense (least effective), which is the usage of PPE. 6 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Other key points to consider about economics and safety: Serious accidents can be critical to meeting contract deadlines. Losing key personnel can spell the end of the business altogether. Loss of business reputation can lead to loss of new or repeat business. Accidents can damage workforce morale. Accident claims mean higher insurance premiums. The challenge for all is: If you think safety is expensive, try pricing an accident! (Lois McMaster-Bujold). Source: OSH (2016) Other key points to consider regarding the economic or financial aspect of safety are listed above. The statement by Lois McMaster-Bujold underscores the unseen financial consequences should safety be undermined in favor of savings or cost-cutting. 7 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Still not convinced? How about some OSH Statistics From the International Labor organization-ILO ( World safety day celebration in 2019) On average, 7,500 die everyday due to work related accidents 160 million incidents of occupational illness every year 270 million work related accidents every year Biggest killers in the workplace: cancer-32%, circulatory diseases-23% , accidents -19%, communicable diseases 17% and others The International Labor Organization-(ILO), releases statistics regarding incidents, illnesses, and accidents in workplaces across all industries. A striking figure is the percentage of accidents leading to death occurring in workplaces. 8 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Philippine OSH Situation (2017) Total Accidents 38,235 Total Injuries 46,283 Non-fatal with lost workdays 20,318 43.9 % Without lost workdays 25,502 55.1% Fatal 463 1% Source: Integrated Survey on Labor & employment-(ISLE ) measures of safety performance (2019) In the Philippines, specifically back in 2017, the total number of recorded accidents is 38,235. Note that the number of accidents does not reflect the count for injuries. Among the tally for that year, 463 were recorded as fatal. 9 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Injury Profile of Most Commonly Profile Injured Worker Male Married 26-30 years old With 1 to 5 years work experience Assigned in the first shift Source: Integrated Survey on Labor & employment- (ISLE ) measures of safety performance (2019) From the Integrated Survey on Labor & employment-(ISLE ) measures of safety performance in 2019, the profile of injury is illustrated above. In ISLE’s presentation material, three areas describing injuries are provided and the dominant types are given. The most common type of injury is the “superficial injuries and open wounds”. In the agent of injury category, machines & equipment plus materials and objects take the top spots. It’s important to note that the top agents of injury are highly prevalent on a construction site and can be easily confirm visually. 10 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Review of Accident vs. Incident illustration Accident: A window cleaner dropping a bucket from a height, which caused injury to a person underneath. Incident: A window cleaner dropping a bucket from a height, which just missed a person standing underneath. This can be considered a near-miss A slightly different circumstances & the person may have been injured As a review, let’s revisit and differentiate more closely the terms ‘accident’ and ‘incident.’ Accidents are defined as ‘occurrences or events that are unexpected, unforeseen, unplanned and unwanted, resulting to damage, injury, loss or death.’ Incidents, on the other hand, are described ‘events that, which under slightly different circumstances, may have resulted in injury or ill health, or damage or loss to property, plant, materials or the environment or a loss of business opportunity” (HSE-UK). 11 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Review of Accident vs. Incident Common reasons for accidents (according to a layman) “Ang malas naman niya!” “Ang T_ _ _ a kasi niya!” “Oras na niya. pana panahon lang yan.” “Kasama yan sa trabaho” These are not real causes but rather can be seen as excuses. Above are common layman expressions regarding the causes of accidents. 12 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Theory for Accidents System theory of Accident Causation Possibility of an accident to occur is dependent on the interaction of work components such as: people , equipment/machineries/tools, materials & environment. Each components (or a combination) are considered source of hazard. The simple expression for accident can be seen as Hazard + Exposure = Accident/ Incident Hazard in another definition is: “any source of potential damage, harm or adverse health effects on something or someone” To gain a better understanding of accidents and their management, it is wise to know the components of an accident. The System Theory of Accident Causation claims that components of accidents regularly interact and are interrelated. These components include people, equipment/machineries/tools, materials and environment. The possibility of an accident is dependent on the interaction of these components, and the components or their combination are considered sources of hazards that can result into either injury or illness. In essence, it takes a hazard and someone exposed to the hazard to produce an accident. (Hazard + Exposure = Accident/Incident). As a review of Hazard definition: “A hazard is any source of potential damage, harm or adverse health effects on something or someone” (CCOSH). Harm refers to physical injury or damage to health. Generally, there are two classification of hazards: Safety and Health, hence the term OSH. Safety hazards have the potential for injury, while health hazards are something that has potential for illness. 13 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Two classifications of Hazards 1. Safety hazards 2. Health hazards Analogy and connection Safety hazard = potential for injury Health hazard = potential for illness In essence, we can establish an analogy of hazards and their corresponding consequences. Again, hazards can either pose the potential for injury or the potential for illness. 14 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Hazards by Category Biological Bacteria, viruses, insects, plants & animals Chemical Gas, vapors, mist, fumes Physical Radiation, noise, temperature extremes, HEALTH HAZARDS pressure, electricity, etc. Ergonomic Repetitive movement, improper set-up of work stations, awkward positions, over exertions Psychosocial Stress, violence Safety Clutters (slipping & tripping), unguarded SAFETY HAZARDS machines, heights (fall), equipment malfunctions, inappropriate use of tools, electricity The table above provides classifications and illustrations for the given two categories of hazards. 15 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Examples of Hazards and corresponding Harm: Source Hazard Harm Object Knife Cut Substance Benzene Leukemia Material Asbestos Mesothelioma Source of energy Electricity Shock, electrocution Condition Wet floor Slips, falls Process Welding Metal fume fever Practice/task Hard rock mining silicosis Above is a table that categorizes hazards into “sources” and details the corresponding harm that a certain hazard might inflict. 16 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Exposure to Hazards When worker is within the “danger zone”, or in a position of “imminent” danger. exposure can be physical- e.g. closed proximity with danger, like a live wire exposure can be environmental- worker is in an unhealthy atmosphere Causes of Accidents 1. Unsafe acts- “any human action that violates a commonly accepted work procedure” (ANSI). removing safety devices Operating equipment without authority Using defective equipment Disregard of SOP or instructions Horseplay Willful intent to injure Working under the influence of alcohol or drugs Exposure to hazards is defined as a condition in which a worker in within the danger zone or in a position of imminent danger. An illustration of which is a worker performing a task less than a few feet away from a live wire. Exposure can be classified as coming from either a physical source or an environmental source. Exposure to a physical hazard could mean , as an illustration, a worker’s hand being too near an unguarded rotating machine. As for environmental source, it could be a worker in an extremely hot working area. Causes of Accidents W.H. Heinrich, an industrialist and pioneer in theories about safety and health in the workplace, claimed that Fatalism, the belief that accidents are bound to happen, is not the real cause of accidents. According to him, the real and immediate causes are 1) unsafe acts which accounts for 88 percent, and 2) unsafe conditions which accounts for 10 percent (W.H. Heinrich). He acknowledges that 2% is unavoidable. To revisit the definition of Unsafe Acts, according to ANSI, they are ‘any human action that violates a commonly accepted work procedure’ (American National Standards Institute). Examples of unsafe acts include: operating equipment without authority; disregard of SOP or instructions; removing safety devices ; using defective equipment; using PPEs improperly; horseplay; willful intent to injure; and, working while under the influence of alcohol or drugs. 17 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Causes of Accidents 2. Unsafe Conditions- “physical or chemical property of a material, machine or the environment which could result in injury to a person, damage or destruction to property or other forms of losses”(ANSI) Therefore, considering the ultimate question in OSH is : “Can accidents be prevented?” Bottomline- o We can control Hazards and manage Exposure. On the other hand, ANSI defines unsafe conditions as “a physical or chemical property of a material, machine or the environment which could result in injury to a person, damage or destruction to property or other forms of losses” Several illustrations for this condition include a slippery and wet floor; dusty work area; congested plant lay- out; octopus wiring; unguarded rotation machines; protruding nails, sharp objects; and, scattered objects in the work area. Now, to deal with the ultimate question in OSH: ‘Can accidents be prevented?’ The resounding answer is ‘Yes!’. This answer is supported by the longstanding study of H.W. Heinrich and the relevant discussion of ANSI on OSH. 18 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Legal bases of OSH A. PD 422-1974 “ The Labor Code of the Philippines” B. OSH Standards, 1979, as amended 1989 C. RA 11058- “An act strengthening compliance with Occupational Safety and Health Standards and providing penalties for violations” enacted January 25, 2019 Its Implementing Rules and Regulation (DO 198-18) D. Department Order No. 13: Guidelines Governing Occupational Safety and Health in the Construction Industry Occupational Safety and Health Standards- OSHS by DOLE comparable to US OSHA In the Philippines, occupational safety and health standards are managed by the Department of Labor and Employment-(DOLE) and by its Occupational Safety and Health Center. The Labor Code of the Philippines, enacted in 1974, is the law governing employment practices and labor relations in the country. It contains books, sections and articles regarding occupational health and safety, and this law primarily grants DOLE its administrative and enforcement jurisdiction. Through the authority from PD 422, DOLE developed the Occupational Safety and Health Standards for guidance and compliance in workplaces. The OSH standards was initially released in 1979, and this document contains rules and regulation regarding OSH, it is further amended in 1989. The version used in this module was released in 2019. This slide illustrates the four relevant legal frameworks for the existence and exercise of OSH in a construction site and the construction industry. RA 11053 and DO 13 will be discussed in the succeeding slides. 19 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Department Order 198-18 (IRR of RA 11058) Main provisions: o Affirms labor as a primary social and economic force and that a safe and healthy workforce is an integral aspect of nation building o Ensures that the laws and standards are fully enforced and complied with by the employers o Ensures a safe and healthful workplace for all working people by affording them full protection against all hazards in their work environment Coverage- all establishments, including special economic zones; utilities; industries such as mining, fishing, OSHS by DOLE Manila cover page construction , agriculture and maritime; contractors & subcontractors. (except public sector) Under the Department Order 198-18 (DO 198-18), serving as the implementing rules and regulations of RA 11058, the following main provisions & principles are given: labor as a primary social and economic force and that a safe and healthy workforce is an integral aspect of nation building ensures that the laws and standards are fully enforced and complied with by the employers ensures a safe and healthful workplace for all working people by affording them full protection against all hazards in their work environment. DO 198-18 outlines the scope and coverage of the law, encompassing all establishments where work is undertaken. It further specifies the inclusions of : Establishments located inside special economic zones and other investment promotion agencies Utilities engaged in air, sea, and land transportation – Industries such as mining, fishing, construction, agriculture, and maritime Contractors and subcontractors including those engaged in the projects of the public sector It should be noted that this DO does not apply to or cover the public sector. 20 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Department Order No. 13: Guidelines Governing Occupational Safety and Health in the Construction Industry Scope: All Construction Activities, whether owned by Government or private sector Highlights: a. accredited safety practitioners (officers ) in all projects b. submittal of construction health & safety programs c. guidelines for evaluation of safety programs d. practitioner’s duties and responsibilities OSHS by DOLE Manila cover page For the construction sector, a more specific compilation of health and safety requirements is outlined in DO 13. DOLE Department Order 13 was released by the Department of Labor and Employment (DOLE) in 1998 in response to increasing concerns regarding safety in construction sites. It is intended to provide support to existing occupational safety and health standards and regulations. Section 4 of DO 13 outlines the coverage of the regulation: “The guidelines shall apply to all construction activities, including demolition, whether owned by the private or the government sector” Highlights and Key features of DO 13 o Requirements on the deployment of accredited safety practitioners for all construction projects o Requirements on the submittal of safety programs for all tenders/bids submitted for all government construction projects o Guidelines for the evaluation of construction safety and health programs for construction sites (revised 03 July 2001) o Safety and Health (OSH) Standards which has to do with the training and accreditation of personnel on occupational safety and health o Defined duties and responsibilities of various safety and health personnel for construction projects. General Elements of site safety plan management leadership assignment of responsibility maintenance of safe working conditions establishment of safety training preparation of an accident record system medical and first-aid system acceptance of personal responsibility of employees 21 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Department Order 198-18 (IRR of RA 11058) Classification of establishments Classification Description High risk establishment Hazards affect the safety and/or health of the workers and the public Medium risk establishment There is moderate exposure to safety and health hazards and with probability of an accident, injury or illness Low risk establishment There is a low level of danger or exposure to safety and health hazards or with low probability to result in accident, harm or illness Department Order 198-18 provides classifications and descriptions of establishments, and shortened descriptions are provided in the table above. 22 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Department Order 198-18 (IRR of RA 11058) Duties of Employers and Workers Duties of Employers Duties of workers Keep workers away from hazards Join in OSH capacity building Provide job safety instructions Use safeguards and safety devices Ensure forms or sources of hazards are under control Comply with all instructions Use only approved equipment and devices Follow all instructions in cases of emergency Comply with OSHS and provide PPE Report hazards Allow workers participation in OSH matters Provide measures to deal with emergencies (training & drills) Comply with reportorial requirement In OSH, knowing the roles of the two main players in a work environment is important. The table above summarizes the responsibilities of both employers and workers regarding OSH. 23 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Department Order 198-18 (IRR of RA 11058) RIGHTS OF WORKERS 1. Right to know all hazards… 2. Right to refuse unsafe work..(without threat or reprisal from owner) 3. Right to report accidents.. 4. Right to Personal Protective equipment (PPE) Free of charge Appropriate type (based on standards) Appropriate size, weight and type to specific workers Besides defining the duties and responsibilities of workers, their rights are also explicitly written. These rights are further reinforced by the other standards related to OSH, and they are presented in the succeeding slides. 24 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Department Order 198-18 (IRR of RA 11058) OSH Reports In prescribed forms A.

The main headings for Table 47 are medicines, medical supplies & equipment, and, medical facilities. Note that the required items on this table depend on the number of workers for an establishment. 29 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Department Order 198-18 (IRR of RA 11058) Health Facilities Medical supplies , at table 47 OSH standard Treatment room or clinic Emergency Hospital/Infirmary and dental clinic The last portion of Table 47 shows four (4) medical facilities which are required for establishments with a worker count of at least 51. A dental clinic or emergency hospital is needed for establishments with more than 2,000 workers. However, an exemption to this rule would mean that a more capable health facility (emergency hospital or dental clinic) within 5-km away or in an urban setup should be within 25-minutes away from the workplace. 30 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Department Order 198-18 (IRR of RA 11058) Workers Welfare Facilities Items o Adequate supply of safe drinking water o Adequate sanitary and washing facilities o Suitable living accommodation such as in construction, shipping, fishing and night workers o Separate sanitary, washing and sleeping facilities for all gender o Lactation station except those establishments as provided for under (DOLE Department Order No.143-15) o Ramps, railings as required o Others as prescribed by the OSH Standard (Section 19 of DO 198-18 at pp 435 of the 2019 updated OSH Standards) As defined in the IRR of RA 11058, the list above outlines the worker’s welfare facilities that should be provided by employers. 31 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Department Order 198-18 (IRR of RA 11058) Safety and Health Training for All workers All workers shall undergo OSH orientation No cost on workers and compensable working time Specialized training for : operation , erection and dismantling of equipment and scaffolds, structural erections, excavations, welding and flame cutting Other Requirements o Safety signages and devices, posted in prominent positions o Safety in use of equipment, requires certification from TESDA or PRC o OSH information available to workers o Construction safety and health programs- with detailed policies DO 198-18 also contains provisions on trainings and orientation of workers on OSH. DO 198-18 specifies that “All workers shall undergo the mandatory workers’ OSH orientation conducted by the safety officer of the contractor or any certified OSH practitioner or consultant”. There are other attributes and stipulations regarding this orientation or training, and they are as follows: No cost on the worker and considered as compensable working time. Personnel engaged in the operation, erection and dismantling of equipment and scaffolds, structural erections, excavations, blasting operations, demolition, confined spaces, hazardous chemicals, welding, and flame cutting shall undergo specialized instruction and training conducted by DOLE or DOLE- accredited Safety Training Organization or PPE manufacturers. Additionally DO 198-18 specifies the following: o Safety signage and devices shall be posted in prominent positions to warn the workers and the public of the hazards in accordance with the OSH Standards in terms of colors and sizes. o Safety in the use of equipment complying the requirements of DOLE including the requirement on training and certification of the operators by the Technical Education and Skills Development Authority (TESDA) and the Professional Regulation Commission (PRC). o OSH information shall be made available to workers including hazards and risks in the workplace, control mechanisms to reduce the risk of exposure to the hazards and emergency and disaster management protocols. 32 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Department Order 198-18 (IRR of RA 11058) Penalties Section 29 OSH, on prohibited acts administrative fines Failure of compliance or violations of OSH rules results in the administrative fines shown above, these are detailed in Section 29 of OSH standards. 33 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Department Order 198-18 (IRR of RA 11058) Penalties Section 29 OSH, on prohibited acts o Failure or refusal to comply- deemed willful when done voluntarily, deliberately and intentionally o Repeated violations= fine + 50%* (repeat violations) o “When the violation exposes the worker to death, serious injury or serious illness, the imposable penalty shall be one hundred thousand pesos (₱100,000.00)” o For two or more non-compliances, all penalties but should not exceed 100,000 daily Section 29 of OSH standards contains the following definitions and provisions regarding “prohibited acts and its corresponding penalties.” Failure or refusal to comply with OSH standards or compliance order shall be deemed willful when done voluntarily, deliberately and intentionally. Repeated violation shall be penalized of the corresponding fine plus an additional fine equivalent to fifty percent (50%) for every instance of repeat violation. When the violation exposes the worker to death, serious injury or serious illness, the imposable penalty shall be one hundred thousand pesos (₱100,000.00) Should there be 2 or more be non-compliances, all penalties shall be imposed; provided that the total daily penalty shall not exceed one hundred thousand pesos (₱ 100,000.00). 34 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Department Order No. 13: Guidelines Governing Occupational Safety and Health in the Construction Industry Salient Features Construction safety & health program- Project manager shall submit to DOLE a comprehensive CHSP prior to start of a construction project. A simplified CHSP for residential buildings 2-storey and below with < 10 workers Safety on Construction Heavy equipment- OSHS by DOLE Manila cover page All operators certified by TESDA All equipment tested by third party testing Org. Now let us pay close attention to DO 13, particularly the preliminary minimum requirements regarding OSH for a construction establishment or a construction project. A Construction Safety and Health Program (CHSP) is essentially needed. A specific construction safety and health program shall be submitted before the start of a construction project. The assigned construction Project Manager shall prepare and submit a comprehensive CHSP to the respective DOLE Regional Office where a project is located. However, only a simplified CHSP is required for construction of residential buildings 2-storey and below with less than 10 workers. DO 13 specifies provisions on Construction Heavy Equipment, and the key provisions are : All operators of heavy equipment shall be certified by TESDA All heavy equipment tested by third party testing organization accredited by DOLE. 35 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Department Order No. 13: Guidelines Governing Number of Construction Site (High-risk workers establishment) Occupational Safety and Health in the Construction 1-9 One SO2 Industry 10-50 One SO3 51-99 One SO2 & One SO3 Salient Features 100-199 One SO2 & One SO3 Safety Officer Assign full time safety officer (for CHSP) 200-250 Two SO3 Number of SOs dependent on workers 251-500 One SO2 & Two SO3 501-750 One SO2 & Two SO3 Safety Officer for heavy equipment 751-1000 One SO2 & Two SO3 One SO for every 10 units of heavy equipment (in a Every Additional S03 or S04 project site) additional 250 Safety Officer of subcontractors Must provide a representative (SO qualifications) DO 13 and related OSHS rules (rule 1047 & rule 1033) specify the obligation of a general contractor to assign a full time and qualified safety officer to oversee the management of the CHSP. The number of safety officers- SOs shall be according to the number of workers as shown in the table above. Additionally, for heavy equipment, a General Constructor shall provide one (1) Safety Officer for every 10 units of heavy equipment assigned to the project site. Also, each subcontractor must provide for a representative, who shall have the same qualifications as a Safety Officer, to oversee the management of the CHSP for the subcontractor’s workforce and specific area of work operations in accordance with the requirements of Rule 1033 of the OSH standards. 36 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Site Safety Standard Elements General government regulations: DO 198-18, DO 13, OSHS (from previous section) 1.

Review and Description of Scaffolds One or more platforms supported by outrigger beams, brackets, poles, legs, uprights, posts, frames or similar rigid support Material is usually steel (tubes and couplers) Supported Scaffolds are the most common type Intended to be temporary Types of supported scaffolds includes; ladder jack, pump jack, tube & coupler, mobile, frame and system. To discuss safety requirements for scaffold setup logically, we will go through the stages of scaffold assembly in the following order: base construction , support structure, access, fall protection, and platform. 1. Base Construction Construction of a firm foundation (sound footing), it must be set on base plates and mud sills, or other adequate foundation. Must be plumbed and braced to avoid swaying and displacement. 2. Support structure Must be able to support its own weight and 4x its intended load. Scaffolds can only be altered under the supervision and direction of a competent person. Regarding bracing, frames and panels must be connected by cross, horizontal or diagonal braces, or a combination. Frames and panels must be joined together by coupling & stacking pins or equivalent. Do not mix scaffold components of different materials, or by different manufacturers….unless otherwise allowed. 50 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Scaffold Safety Types of supported scaffolds a. Ladder jack b. Pump jack c. Tube & coupler d. Mobile e. Frame f. System Excerpt from UP-NEC-ICPS Above are the illustrations of common or traditional scaffold systems used in a construction project. 51 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Scaffold Safety Common Hazards a.

Fuel b. Energy (heat source) c. Oxidizer (air) Prevention is, therefore, based on eliminating or minimizing one of the components of the fire triangle. Fire Prevention measures in a job site o Regular upkeep of job site o Avoid unnecessary stockpiling of combustible materials o Adopt safety precautions o Avoid burning waste materials o Adopt site rules on smoking The Fire Triangle identifies three main components of any fire: fuel, energy(heat source), oxidizer (air). If any of these is missing a fire cannot continue. Prevention, therefore involves eliminating or minimizing the interaction of these components. Fire Prevention measures in a job site o Keep tidy site and make sure rubbish is cleared away promptly and regularly. o Avoid unnecessary stockpiling of combustible materials. o Consider the need for special precautions in areas where flammable atmospheres may develop. o Avoid burning waste materials on site wherever possible. o Make sure everyone abides by site rules on smoking. 57 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Fire Safety Common causes of fire a. Short-circuiting, overloading or poor joints in electrical cables. b. Defective electrical equipment and wiring. c. Improper use or storage of flammable liquid such as thinner and paint. d.

Knowledge & review of materials ad conductors and insulators are needed General indicators of Human resistance to Electric Current 8 – 15mA Pain 15-20mA Pain, loss of muscular control 20-100mA Intense pain & paralysis of breathing muscles; possible suffocation Excerpt from UP-NEC-ICPS 100-200mA Ventricular fibrillation which will cause death > 200mA is possible to come from a 220V convenience outlet In electrical safety, the guiding principles are: (1) rendering the source as electrically dead and (2) providing barriers to prevent contact. Knowing electrical conductors to be the following: A material having many free electrons that can move easily. Metals (especially copper) are good conductors. Copper wires will allow billions of electrons to flow in the same direction to create a great source of electrical current. On the other hand, electrical insulators are material with few free electrons that cannot move easily. Rubber, dry wood, porcelain, and clay are considered good insulators. Insulators prevent electricity from flowing where it should not flow and control the flow of electricity in order to prevent accidents. 60 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Electrical Safety When working with Electrical equipment: NEVER ALWAYS Make repairs unless the power is off and Remove all conductors such as metal jewelry and unplugged from the circuit watches. Use equipment/ tools with frayed cords. Remove portable phones or other electronic devices. Operate, repair, submerge or work with Use required PPE such as insulated tools, gloves, and equipment in or around water floor mats. Keep your skin dry. Table above summarizes the different precautions and safety measures for activities involving electrical equipment. 61 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Electrical Safety From: “29 safety failure that would give OSHA nightmares-fail blog ” From: “29 safety failure that would give (cheezburger.com) From: “20 reasons why women live longer OSHA nightmares-fail blog ” than man” by-skirmante retrieved from Bored Panda (cheezburger.com) Above are some images showing unsafe practices on electrical systems and components. 62 UP DILIMAN| INSTITUTE OF CIVIL ENGINEERING Personal Protective Equipment-PPE -any Physical Material or Equipment that is placed between the Employee and Workplace Hazards o To be selected and provided to employees, where hazards cannot be sufficiently abated or removed.
