Study Notes
Occupational Safety and Health (OSH) Overview
- Understanding OSH concepts is crucial for effective implementation in workplaces.
- Costs associated with accidents can be categorized into direct (injuries, damages, legal infractions) and indirect (productivity loss, reputation damage).
Cost of Accidents
- Direct costs include injury, sickness, property damage, legal fines, and lost time.
- Indirect costs encompass productivity delays and loss of business reputation.
- Iceberg Theory illustrates that 98% of accidents are preventable; only 2% are due to unavoidable factors.
Accident Risks
- Occupation-related risks emerge from acts of omission (failure to act) and acts of commission (faulty action).
- Unsafe conditions and unsafe acts are common precursors to incidents.
Industrial Hygiene Concepts
- Involves identifying workplace hazards, evaluating risks, and controlling hazards.
- Hazards fall into two categories:
- Safety hazards (mechanical, ergonomic risks).
- Health hazards (conditions leading to illness).
Risk Classification
- Risk evaluation identifies low-risk (monitor), medium-risk (develop control plans), and high-risk (stop and investigate) scenarios.
Hierarchy of Controls
- Control measures should follow the hierarchy: elimination, substitution, engineering controls, administrative actions, and personal protective equipment (PPE).
Boiler Safety (Rule 1160)
- Steam boilers are closed vessels designed to generate steam above atmospheric pressure.
- Various types include power boilers, miniature boilers, low pressure heating boilers, and hot water boilers, each with specific size and pressure definitions.
- Operational and safety standards include regular inspections, pressure tests, and the implementation of safety valves.
Unfired Pressure Vessels (Rule 1170)
- Unfired pressure vessels hold steam, hot water, gas, or air, excluding portable gas cylinders.
- Safety valves must be set within ±10% of designed pressure, with adequate drainage systems.
Internal Combustion Engines (Rule 1180)
- Defined as engines that generate energy through a burning fuel mixture.
- Horsepower measures performance and equates to 33,000 pounds of force or 746 watts.
Machine Guarding (Rule 1200)
- Machine guarding is essential for protecting workers from mechanical hazards through both physical barriers and active safety measures.
- Employers must ensure that all machinery includes necessary protective devices.
Additional Safety Considerations
- Guidelines exist for various components of safety frameworks, including guard requirements, structural specifications, and safety protocols within engine rooms and boiler operations.
- Comprehensive planning for boiler and pressure vessel installations includes room layouts and detailed construction drawings.
Summary of Key Regulatory Rules
- Rule 1160 outlines the definitions and operational standards specific to steam boilers and related equipment.
- Rule 1170 covers health and safety regulations for unfired pressure vessels.
- Rule 1180 establishes safety measures for internal combustion engines.
- Rule 1200 emphasizes the necessity of machine guarding to ensure worker safety against mechanical mishaps.
These notes provide a fundamental understanding of the principles and regulations governing occupational safety and health, highlighting crucial areas and specific requirements for maintaining workplace safety.### Machinery Safety
- Distance from the floor to machinery parts must be at least 7 ft.
- Pulleys must be spaced wider than the belt width for safety.
- Hood guards are essential on swing saws; a hinged design is preferable.
- Limit chains and latches prevent saws from moving beyond designated areas or rebounding.
- Counterweights ensure the automatic return of saws.
- Hood or guard for every circular and fed table saw should extend a minimum of 50mm.
- Anti-kickback devices are critical for preventing back-throwing of stock.
- Fixed guards protect operators' fingers on both sides of machinery.
- Interlocking gate guards disable machinery until operators' hands are clear.
- Limited ram travel in machines should not exceed 10mm.
- Swept guards force operator's hands away from danger zones.
- Two-handed trip devices maximize safety by requiring both hands to operate machines.
Electrical Safety (Rule 1210)
- Electrical equipment installation must comply with Bureau approval.
- Temporary installation certificates are issued for construction and amusement projects.
- Temporary electrical outlets are limited to 20, providing 4 kilowatts.
- Validity of temporary certificates is up to 120 days for ongoing constructions and 60 days for amusements.
Elevators and Related Equipment (Rule 1220)
- Elevators are defined as mechanisms for hoisting and lowering materials using a car or platform.
- The hoistway is crucial for elevator operation, encompassing the vertical travel path.
- Safety devices like buffers and counterweights ensure safe functioning.
- Elevator pits are designed for the lowest landing door while landing areas facilitate passenger discharge.
- Emergency stop switches cut power during urgent situations, protecting user safety.
Identification of Piping Systems (Rule 1230)
- Piping systems must have clear identification through stenciled legends or color-coded markings.
- Different fluid types are represented by specific colors: e.g., water (green), air (light blue), cryogenic gases (yellow ochre), and more.
- Tags are utilized for smaller pipes, while overhead lettering should be below their horizontal center line.
Fire Safety Standards (Rule 1940)
- Fire ratings specify how long materials can withstand fire exposure.
- Exits must be accessible within 5 minutes and comply with distance regulations based on occupancy type.
- Facilities need fire alarm systems, and exits should not rely on doors that present obstacles like sliding or revolving mechanisms.
Occupational Health Services (Rule 1960)
- Occupational health services provide essential support for workers and employers.
- First-aid personnel must be certified to act in emergencies.
- Health professionals organize preventative care through examinations and treatments.
- Emergency clinics should be close to workplaces to manage health issues efficiently.
Construction Safety (Rule 1410)
- Scaffold designs must ensure structural integrity; standards must be securely fastened.
- Provisions must be made to protect against falling materials, requiring safety gear for workers.
- Excavations over 1 meter must have shoring to prevent collapses, with specific requirements for deeper excavations.
- Worker lift limits are defined (50kg for males, 25kg for females) to ensure safety during manual handling.
Pesticides and Fertilizers (Rule 1950)
- Pesticides control pests comprehensively, while fertilizers promote plant growth.
- Different classes of pesticides aimed at various environments impose specific handling protocols.
- Safety measures mandate clear labeling for products, including usage instructions and hazard warnings.
Quiz Practice (Quiz 2)
- Familiarize with key terms like working pressure in kg/cm² (psig).
- Understand the significance of personal protective equipment for job safety.
- Recognize age limits for boilers based on pressure ratings.### Definitions and Equipment
- Water pressure tank: A pressure vessel used for heating water via live steam or steam coil, or for storing cold water dispensed by pressure.

- Installation: Refers to the assembly or connection of power piping designed for safety operations.
Identification and Emergency Protocols
- Piping identification: Water piping is marked green; air piping is marked light blue.

Fire Safety and Health Personnel
- Fire drills: Must be conducted at least twice a year unless higher frequency is mandated by local authorities.
- Occupational Health Personnel: Includes qualified first-aiders, nurses, dentists, or physicians engaged for health services at a workplace.
