Study Notes

Personal Protective Equipment (PPE) Overview

Employers are responsible for procuring PPE for their workers.
Safety shoes are exempt from employer obligations regarding PPE procurement.

Job Hazard Assessment

A job hazard assessment (JHA, SRA, etc.) must be conducted to identify necessary PPE.
The employer is required to maintain a copy of the JHA for reference.

Hard Hat Classifications

Class E: Electrical helmets tested for protection up to 20,000 volts.
Class G: General helmets tested for low voltage protection at 2,200 volts.
Class C: Conductive helmets that lack any electrical protective testing.

Hard Hat Safety Zone

The safety zone is the gap between the hard hat's suspension and outer shell, which absorbs impacts.
A minimum distance of 1 inch is mandated for the safety zone.

Hard Hat Training Requirements

Employees must learn the necessity of head protection, limitations, and proper usage of hard hats.
Training includes instruction on checking and inspecting hard hats.

Eye Protection Requirements

Eye protection must adequately shield against specific hazards and be comfortable to wear.
Fit should be snug without obstructing vision, and it must be durable and easy to clean.

Hearing Protection and Noise Reduction Rating (NRR)

To assess hearing protection: subtract the C-weighted Time-Weighted Average from the NRR or adjust an A-weighted dose by subtracting 7 dB from the NRR.

Training on Hearing Protection

Training must cover effects of noise, use of hearing protectors, and their advantages and disadvantages, along with care instructions.

Situations Requiring Respirators

Respirators are required when exposure exceeds permissible limits or when engineering controls are unfeasible.
They are essential in regulated areas and emergencies.

Types of Respirators

Air-purifying respirators filter contaminated air through media.
Powered air-purifying respirators enhance filtration with a blower.
Self-contained breathing apparatuses supply air from a closed system.
Supplied-air respirators provide fresh air through an air line.

Fit Testing for Respirators

Qualitative fit tests determine respirator adequacy based on user response to irritants or odors.
Quantitative fit tests measure the actual leakage into the respirator.

Respiratory Protection Program Components

A comprehensive program includes selection procedures, medical evaluations, fit testing, usage instructions, maintenance schedules, and training requirements.

Respirator Training Requirements

Training covers the necessity and limitations of respirators, inspection, maintenance, cleaning, and proper usage.
Annual training sessions are mandated for employees using respirators.
