PPE protect the operators from being exposed to physical, electrical, mechanical, chemical, radiological and other workplace hazards like falls, trips, slips etc..  CLASSIFICATION OF PPE PPE are classified on the basis of the type of protection that they offer. o Head Protection – Hard hats, Safety helmets o Eye Protection – Safety glasses, Goggles, Face Shields, Visors o Hearing Protection – Ear plugs, Ear muffs Health Safety and Environment o Respiratory Protection – Masks, Respirators, Self-contained breathing apparatus o Hand Protection – Gloves, Barrier creams EGHS1140 o Foot Protection – Safety Shoes, Boots o Skin Protection – Coveralls, Full body suits, Heat resistance suits, Apron o While Working at Heights - Safety harness, Fall arresters o Other Specific PPE – Sleeve protector, Finger guard for Sewing, Disposable clothing while working with chemicals and radiations, cold protective clothing for working near furnaces, Trousers pats and leather jackets for welding etc.  3.2 SAFETY HELMETS OSHA mandates the requirement of head protection in workplaces and it is the employer’s responsibility to ensure that the workers head is protected by means of safety helmets and hard hats as per the regulations of the work environment. Health Safety and Environment Safety helmets used in industrial application must comply the EN397 standard and OSHA’s safety helmet requirements 29 CFR 1910.135: general industry workers and 29 CFR 1926.100: construction and demolition EGHS1140 workers. Both the standards make it compulsory to workers to wear the helmets when they are at the risk of falling objects, contact with electrical hazard, bumping their heads etc. Typical Construction safety Helmets are colour coded as well so as to easily identify helmet the person and his responsibility. Main properties of safety helmet are resistance to important penetration, shock absorption, heat, electrical and flammability.  SAFETY HELMET – COLOR CODING Health Safety and Environment Choosing The Right Safety Helmet EGHS1140  3.3 SAFETY SHOES OSHA standards make it mandatory for the workers to wear the safety toe footwear all the time he is working and the employers are duty bound to provide the safety shoes for their employees. Safety shoes must have a leather upper part and oil resistant non- skid soles complying to the OSHA standard 29 CFR 1910.136. Health Safety and Environment it has electrical resistance Safety shoes construction and parts EGHS1140 Safety shoes protects the feet, especially the toes against the drop or fall of heavy objects. It will also offer good grip on the floor and prevents slipping. Generally electrical insulation is also provided on safety shoes. Safety shoes or boots provides protection from penetrating or crushing, rolling equipment, electrical hazards, hazardous materials, venomous snakes etc. They are generally mandatory in most industries.  3.4 EAR PLUG Two main types of hearing protection that obstruct passage of sound to the ear drum, middle ear and inner ear. Ear plugs are generally made from polyurethane foam and are disposable. Earmuffs are more rigid which covers the outer ear with protective cups consisting of acoustic seals made up of polyurethane foam and filled with sound absorbing materials. Health Safety and Environment EGHS1140 Ear plug, earmuffs, and mandatory safety sign for hearing protection (Excessive noise entering the human system affects the nervous systems, hampers the functioning of cochlea which in turn causes balancing problems of atmospherics pressure and inside pressure of the body and tinnitus (ringing in the ears)).  3.5 SAFETY GLOVES COMPARISON CHART AND SELECTION GUIDE Safety gloves are essential to protect the hands from getting exposed to hazardous chemicals and dangerous materials and infection and contamination that might occur as a result of that. Protective gloves are selected on the basis of hazards involved, Health Safety and Environment comfort required, degree of dexterity, need or ability to grip, temperature protection required etc. Nitrile gloves offers protection against most of the hazardous EGHS1140 chemicals and infectious agents. Other different types of gloves available are Fabric gloves, Coated fabric gloves, leather gloves, plastic gloves, latex gloves, Kevlar gloves, butyl rubber gloves, impact resistant gloves, puncture resistant gloves, aluminized gloves for working with heat etc. OSHA standard CFR 1910.138 is the standard governing the protection of hands of employees when they are exposed to hazards. The below provide a comparison of different types of gloves  3.5 NITRILE GLOVES, COTTON GLOVES, LATHER/ WELDING GLOVES what's the difference Health Safety and Environment between them EGHS1140  3.5 NITRILE GLOVES, COTTON GLOVES, LATHER/ WELDING GLOVES Health Safety and Environment EGHS1140  3.6 SAFETY HARNESS Safety harness is a PPE that is provided to safeguard persons working at higher altitudes for the injury or other fatality that might result from falling from heights. It is made from rope and braided wire cables. OSHA standard 1910.140 is Health Safety and Environment covering the regulations for safety harness and fall protection. Safety harness are generally grouped into four classes: vid in yt: Fall Protection: Fall Arrest (4 of 6) EGHS1140 Class Description Class 1 Body belts that is designed to restrict a person in falling from work positions and stops within 3 feet. This is generally attached to ladders, escape ropes etc. Class 2 Seat harness used generally for retrieving persons from deep holes, tanks etc most one used Class 3 Full body harness that is capable of arresting the most dangerous and severe fall Class 4 Suspension belts used to suspend a worker for raising and lowering as in the case of a boatswain’s chair (normally used in glass pane cleaning of high-rise buildings) Class 1: a research found out that the BODY BELTS aren't that safe  3.5 SAFETY HARNESS Health Safety and Environment EGHS1140 4 1 2 3 Figure Class I, Class II, Class II and Class IV Harnesses  3.7 SAFETY SPECTACLES, GOGGLES AND FACE SHIELDS Based on the risk assessment different types of eye protection equipment are selected and is available in different styles. Street safety glasses, prescription glasses are very much different from industrial safety glasses and can never be considered equivalent. Mainly they are falling in three categories: Safety spectacles, safety goggles and face shields. Safety spectacles provide protection against low Health Safety and Environment low heat, small particles which is in a low speed energy projectiles like metals chips, scraps etc. Safety goggles offers protection against high energy projectiles and dusts. EGHS1140 Face shields offer protection against high energy projectiles and also different type of radiations. Visors are alternative equipment for equipment which are comparatively cost effective and also having wire screen and heat reflecting protections. OSHA standard 29 CFR 1910.132 and 1910.133 governs the regulations for eye protection and sets the standards for safety spectacles, goggles and face shields. Safety spectacles, safety goggles, Face shield and welding face shield  3.7 SAFETY SPECTACLES PROTECTION before wearing anything, you have to check the equipment Standard quality of a safety glass can be identified by running the fingers along the edges as tempered glass would be completely smooth without any scuffs or ridges. Also printed kitemark would be found in the corners of the Health Safety and Environment glasses: BS EN14449 for laminated glass and BS EN12150 for toughened glass. Yet another safety precaution regarding eye protection is to be EGHS1140 taken by those wearing contact lenses, that they should not go 3dsat near high temperature sources. This would lead to melting of contact lenses and causing permanent blindness. Also, those wearing prescription glasses should wear safety glasses over the same.  3.8 COVERALLS There are a lot of protective clothing that provides protection against a wide range of hazards that include heat, cold, radiation, chemical attack abrasions etc. Health Safety and Environment Protective outer garments are generally made of PVC material and indoor garments like coveralls and coats are made up of EGHS1140 cotton and polycotton. Persons working in petroleum industries are allowed to wear only fabric made up of pure cotton due to static electric discharge of other materials. OSHA standard 1910.132 covers the quality standards of skin protection PPE.  3.8 COVERALLS Health Safety and Environment EGHS1140 Different coveralls, aprons and coats for body and skin protection  3.9 HEAT / FLAME RESISTANCE SUIT The main purpose of heat resistant or flame-resistant clothing (FRC) offers protection Health Safety and Environment against exposure to hydrocarbon flash fires. So, it is mandatory in refineries, EGHS1140 petrochemical industries etc. OSHA standard 29 CFR 1910.269 makes it mandatory for employees exposed to flames, electric arcs, employees operating over 600 volts etc.  3.10 Self-Contained Breathing Apparatus (SCBA) SCBA delivers air to the person wearing it from a cylinder which can be controlled by a valve into the full-face mask. It is used by persons working in heavy presence dust, gases, vapour, during fire, smoke and tunnels Health Safety and Environment EGHS1140  Conclusion Health Safety and Environment EGHS1140 When it comes to the industrial safety employers have few rights and many responsibilities, while employees have few responsibilities and many rights Employers are responsible for providing appropriate PPE of suitable quality and complying OSHA standards On the contrary employees have many rights in demanding the availability of all the PPE, safety precautions, and safety procedures required for the operation he is engaged  Laboratory Experiments Analyzing the conditions and selecting suitable PPE for a Health Safety and Environment specific application and writing reports EGHS1140  Class Assignments 1.
