Answer 42

1081.04

Question 43

When must I provide PPE?

Answer 43

* Their work environment presents a hazard or is likely to present a hazard to any part of their bodies; * Their work processes present a hazard or are likely to present a hazard to any part of their body; * During their work, they might come into contact with hazardous chemicals, radiation, or mechanical irritants; * You are unable to eliminate their exposure or potential exposure to the hazard by engineering, work practice, or administrative control.

Question 44

: If employees wear eyeglasses with prescription lenses,may I consider these as eye protection?

Answer 44

: No. Eye glasses designed for ordinary wear do not provide the level of protection necessary to protect against workplace hazards.

Question 45

Could employees wearing hard hats and working at elevations create a potential hazard for the employees working below?

Answer 45

To protect employees working below, you must provide chin straps for the protective helmets worn by employees working at higher elevations such as aerial lifts or at the edge of a pit. The chin straps should be designed to prevent the hard hats from being bumped off the employee’s heads.

Question 46

: Is there one kind of glove that will protect against all workplace hazards?

Answer 46

No. The nature of the hazard(s) and the operation to be performed will determine your selection of gloves. The variety of potential occupational hand injuries may make selecting the appropriate pair of gloves more difficult than choosing other protective equipment. Exercise care in choosing gloves designed for the particular circumstances of your workplace

Question 47

Why should workers be outfitted with the more expensive industrial respirators when look alike “nuisance masks” are available?

Answer 47

Respirators filter toxic dusts and mists commonly found in industrial and manufacturing settings, such as welding, grinding, sanding, and maintenance or repair applications. Respirators meet minimum performance standards and the government approved agencies certify them. A “nuisance dust mask” on the other hand, has no approved government certification and meets no government performance standards. Nuisance dust masks should not be used when exposures to hazardous conditions may exist. The filtration efficiency of nuisance dust mask is lower and the face seal around the nose and mouth is less effective than that of approved respirators

Question 48

: Is cotton sufficient as earplugs?

Answer 48

: Plain cotton does not effectively protect against occupational noise. You may, however, choose from several products that are effective at protecting your employees’ hearing. Appropriate hearing protectors include: single-use earplugs, pre-formed or molded earplugs, canal caps, and earmuffs.

Question 49

Once I have selected the specific PPE for my workers, how do I make sure they use it properly?

Answer 49

Train your workersto use the protective equipment. Teach them to know… * Why the PPE is necessary as well as the specific hazards in their work area. * How the equipment will provide protection to them. * The limitations of the PPE * How to properly put on the protective equipment * How to identify signs of wear such as scuffed, cracked, holes, etc. * How to clean and maintain the PPE * The company PPE policy, rules and regulations
