What 29 CFR 1926.28 requires (plain English)
29 CFR 1926.28 is the general personal protective equipment requirement in construction, part of Subpart E (Personal Protective and Life Saving Equipment). It establishes the employer's overarching duty regarding PPE, complementing the equipment-specific standards that follow.
The rule makes the employer responsible for requiring the wearing of appropriate personal protective equipment in all operations where there is an exposure to hazardous conditions, or where Part 1926 indicates the need for using such equipment to reduce the hazards to the employees. The key word is REQUIRING: the duty is not merely to provide PPE but to require and enforce its use wherever a hazardous exposure exists.
1926.28 works as the general umbrella over the specific construction PPE standards: head protection (1926.100), eye and face protection (1926.102), hearing, respiratory, and the criteria in 1926.95. Because it is written broadly ("all operations where there is an exposure to hazardous conditions"), OSHA can cite it where a real hazard exists and appropriate PPE was not required, even if no more specific provision names that exact situation. It is the construction counterpart to the general PPE duty and the enforcement backstop for PPE use on site.
