- 3. 10/19/2024 3 Introduction Personal protective equipment or PPE is protective equipment used for work related occupational health and safety purposes. Devices used to protect workers from injury or illness resulting from contact with chemical , radiological, physical, electrical, mechanical, or other workplace hazards.
- 4. 10/19/2024 4 Why PPE is needed? PPE is designed to protect the worker’s body from hazards and injuries such as blunt impacts, electrical hazards, heat, chemicals, and infection, etc. All employees, depending on their jobs, are required to cooperate in the strictest observance of safety legislation, regulations, guideline policies and procedures at all time.
- 5. 10/19/2024 5 This includes wearing safety shoes, hearing protection, goggles, gloves, helmets, safety vests, etc. Depending on their jobs, employees are required to wear all PPE while they are in the manufacturing plant
- 6. 10/19/2024 6 Standard For Personal Protective Equipments OCCUPATIONAL HEALTH and SAFETY ADMINISTRATION OHSA standards requires employer to: 1. Conduct documented assessment of workplace hazards 2. Provide appropriate PPE when required 3. Provide training
- 7. 10/19/2024 8 Type of PPes Head protection Eye and Face protection Hearing protection Respiratory protection Arm and Hand protection Foot and Leg protection Protective clothing
- 8. 10/19/2024 9 Eye and face protection Approved eye and face protection shall be worn when there is reasonable probability that an injury can be prevented or reduced by wearing such equipment.
- 9. 10/19/2024 10 When must Eye Protection be Provided? When any of these hazards are present: 1. Dust and other flying particles, such as metal shavings or sawdust 2. Corrosive gases, vapors, and liquids 3. Molten metal that may splash 4. Potentially infectious materials such as blood or hazardous liquid chemicals that may splash 5. Intense light from welding and lasers
- 10. 10/19/2024 11 Eye and face protection Eye and face protection is used to Protect eyes from hazards from: 1. Airborne particles 2. Liquid chemicals 3. Molten metals 4. Light radiation 5. Dust
- 11. Hazard Hazard Type Related tasks Impact Flying objects such as large chips, fragments, particles, sand, and dirt. Chipping, grinding, machining, masonry work, wood working, sawing, drilling, riveting, sanding, etc. Heat Anything emitting extreme heat. Furnace operations, pouring, casting, hot dipping, welding, etc. Chemicals Splash, fumes, vapors, and irritating mists. Acid and chemical handling, degreasing, plating, and working with blood. Dust Harmful dust. Woodworking, buffing, and general dusty conditions. Optical Radiation Radiant energy, glare, and intense light Welding, torch-cutting, brazing, soldering, and laser work.
- 12. 10/19/2024 13 Ideal Criteria of Eye PPEs 1. Protects against specific hazard(s) 2. Comfortable to wear 3. Does not restrict vision or movement 4. Durable and easy to clean and disinfect 5. Does not interfere with the function of other required PPE 6. Non inflammable and non allergic 7. Cosmetically acceptable 8. Non costly and easy to replace
- 13. 10/19/2024 14 Common materials Glass Plastic 1. Polycarbonate 2. Cellulose Acetate 3. PMMA 4. CR-39
- 14. 10/19/2024 15 TYPES 1. Safety Glasses 2. Goggles 3. Face Shields 4. Welding Helmets 5. Laser Safety Goggles
- 15. 10/19/2024 16 SAFETY Goggles In many working environments it is possible to simply provide over – goggles , particularly to spectacle wearers But these should not be seen as a long term solution as physical and visual comfort will be limited. Safety goggles are most useful to protect from splashes and / or provide high impact resistance.
- 16. 10/19/2024 17 Needed to be used when protection is required against chemicals or particles Only provide protection to the eyes Goggles are not considered a sources of protection for the whole face, and cannot be used for this purpose.
- 17. 10/19/2024 18 The Canadian Standards Association (CSA)- certifies that safety glasses have plastic polycarbonate lenses. The manufacturer or supplier logo must be marked or etched on all approved safety lenses, frames (front and temple), removable side shields, and other parts of the glasses, goggles, or helmets. Safety frames are stronger than street-wear frames and are mostly heat resistant.
- 18. 10/19/2024 19 Safety goggles are heavier and less convenient to use than spectacles or eyeshields. They are made with a flexible plastic frame and one-piece lens and have an elastic headband. They afford the eyes total protection from all angles as the whole periphery of the goggle is in contact with the face.
- 19. 10/19/2024 20 Goggles may have toughened glass lenses or have wide vision plastic lenses. The lenses are usually replaceable. Safety goggles are more prone to misting than spectacles. Double glazed goggles or those treated with an anti-mist coating may be more effective where misting is a problem. Where strenuous work is done in hot conditions, 'direct ventilation' goggles may be more suitable.
- 20. 10/19/2024 21 However these are unsuitable for protection against chemicals, gases and dust. 'Indirect ventilation' goggles are not Perforated, but are fitted with baffled ventilators to prevent liquids and dust from entering. Indirect ventilation goggles will not protect against gas or vapour.
- 22. 10/19/2024 23 Indirect vented goggles Goggles with indirect ventilation have a venting system that does not allow for direct contact of particles to the interior of the goggles. This is achieved by adding angled vents which face away from the front lens. Indirectly vented safety goggles are the ideal choice for dealing with chemicals where chance of splash is possible. These goggles are not as well ventilated as direct vent goggles.
- 23. 10/19/2024 24
- 24. 10/19/2024 25 Direct vented goggles Safety goggles with direct ventilation are goggles that have ventilation holes directly through the frame of the goggles to the inside environment. These ventilation holes are generally very small and placed around the top and/or sides of the goggles. Direct vented goggles are great when there is a large amount of fine debris floating around in the air of the work area. Direct vent safety goggles are a great choice unless working with chemicals, liquids or extremely fine particle materials.

- 27. 10/19/2024 28 Cup type safety goggles The elastic headband provides a tight fit to the face and can provide protection against molten metal , flying particles , dust , etc. The housing is generally made of polyvinyl chloride. They sometimes have adjustable nasal fitting and , if the rims have screws , the lenses can be replaced or exchanged for another type of lens , e.g. tinted or impact resistance
- 28. 10/19/2024 29
- 29. 10/19/2024 30 Box type safety goggles One piece lens made of cellulose acetate , polycarbonate or possibly toughened glass and the housing is made of PVC , which gives a good fit around the brows and cheeks. They are often lightweight with good ventilation with no obstruction of vision. It is possible to wear prescription spectacles underneath but comfort can Vary

- 31. 10/19/2024 32 Safety glasses/ spectacles Protects eyes and area around the eyes from impact, dust, and splashes
- 32. 10/19/2024 33 Safety Spectacles Safety Spectacles are similar in appearance to prescription spectacles May incorporate optional side shields to give lateral protection to the eyes. To protect against impact, the lenses are made from tough optical quality plastic such as polycarbonate. Safety spectacles are generally light in weight and are available in several styles with either plastic or metal frames.
- 33. 10/19/2024 34 Most manufacturers offer a range of prescription safety spectacles which are individually matched to the wearer. Tinted or shaded lenses may be needed for protection against glare Tinted or shaded lenses may limit your vision when moving from bright to dim areas
- 34. 10/19/2024 35 Prescription lenses present specific hazards such as: 1. Dust caught under the lens 2. Chemical reaction with contacts If prescription glasses are worn you must wear: 1. Goggles and/or other protective devices Designed to fit over glasses or 1. Protective eyewear ground to your prescription
- 35. 10/19/2024 36 Eye shields EYESHIELDS are like safety spectacles but are heavier and designed with a frameless one-piece moulded lens. Vision correction is not possible as the lenses cannot be interchanged. Some eye shields may be worn over prescription spectacles.
- 36. 10/19/2024 37 Face Shields These are headband – supported visors that cover the face and neck , and are used to provide protection from flying particles , molten metal , and chemical splashes. One major advantage is that can easily be worn over prescription spectacles or other types of eye protection if required .
- 37. 10/19/2024 38 Face Shields Provide excellent field of view. Made from either polycarbonate or cellulose acetate. Provide protection in occupation such as motorcycling , cricket and security industry Faceshields are heavier and bulkier than other types of eye protector but are comfortable if fitted with an adjustable head harness.
- 38. 10/19/2024 39 Face Shields They do not protect against dusts, mist or gases. Visors on brow guards or helmets are replaceable. They are generally not prone to misting. Face shields with reflective metal screens permit good visibility while effectively deflecting heat and are useful in blast and open-hearth furnaces and other work involving radiant heat
- 39. 10/19/2024 40 STANDARD : ANSI : Z87 = BASIC IMPACT Z87+ = HIGH IMPACT
- 40. 10/19/2024 41 Welding Helmets Constructed of vulcanized fiber or fiberglass and fitted with a filtered lens, welding shields protect eyes from burns caused by infrared or intense radiant light They also protect both the eyes and face from flying sparks, metal spatter and slag chips produced during welding, brazing, soldering and cutting operations. OSHA requires filter lenses to have a shade number appropriate to protect against the specific hazards of the work being performed in order to protect against harmful light radiation.

- 42. 10/19/2024 43 Laser safety goggles These specialty goggles protect against intense concentrations of light produced by lasers. The type of laser safety goggles an employer chooses will depend upon the equipment and operating conditions in the workplace.
- 43. 10/19/2024 44 Laser light radiation can be extremely dangerous to the unprotected eye and direct or reflected beams can cause permanent eye damage. Laser retinal burns can be painless, so it is essential that all personnel in or around laser operations wear appropriate eye protection.
- 44. 10/19/2024 45 Laser safety goggles should protect for the specific wavelength of the laser and must be of sufficient optical density for the energy involved. Safety goggles intended for use with laser beams must be labeled with the laser wavelengths for which they are intended to be used, the optical density of those wavelengths and the visible light transmission.

- 46. 10/19/2024 47 Caring of eye protectors The lenses of eye protectors must be kept clean as dirty lenses restrict vision, which can cause eye fatigue and lead to accidents. There are two methods for cleaning eye protectors. Glass, polycarbonate and other plastic lenses can be cleaned by thoroughly wetting both sides of the lenses and drying them with a wet strength absorbent paper. Anti-static and anti-fog lens cleaning fluids may be used, daily if necessary, if static or misting is a problem.
- 47. 10/19/2024 48 Alternatively lenses can be 'dry' cleaned by removing grit with a brush and using a silicone treated non-woven cloth. However plastic or polycarbonate lenses should not be 'dry' cleaned as the cloth used in this method can scratch them. Eye protectors should be issued on a personal basis and used only by the person they are issued to. If eye protectors are re-issued they should be thoroughly cleaned and disinfected
- 48. 10/19/2024 49 Eye protectors should be protected by being placed in suitable cases when not in use. Eye protector headbands should be replaced when worn out or damaged. Lenses that are scratched or pitted must be replaced as they may impair vision and their resistance to impact may be impaired. Transparent face shields must be replaced when warped, scratched or have become brittle with age.
