When do I need eye or face protection?

Whenever workers are exposed to flying particles, molten metal, liquid chemicals, acids, gases, vapors, or injurious light. Protection must meet ANSI/ISEA Z87.1, and side protection is required where flying objects are a hazard. Regular prescription glasses do not qualify unless they are rated safety eyewear or worn under approved goggles or a face shield.

Do respirators require a fit test?

Yes. Tight-fitting respirators require a fit test before first use, at least annually, and whenever facial changes could affect the seal. Respirator use also requires a medical evaluation and a written respiratory protection program. Voluntary use of filtering facepieces still triggers certain program requirements.

How do I know if my gloves are right for the task?

Match the glove to the specific hazard — cut-resistant for sharp materials, chemical-resistant for solvents and acids, and heat-resistant for hot work — and choose the correct size for each worker. Loose or oversized gloves are themselves a hazard near rotating machinery, where they can be caught and pull the hand in.

How often must PPE training be repeated?

OSHA requires initial training before a worker is assigned to a task that needs PPE, and retraining whenever the workplace changes in a way that makes the previous training obsolete, when the type of PPE changes, or when a worker demonstrates a lack of understanding or is observed misusing equipment. Respirator users specifically must be retrained at least annually and re-fit-tested on the same schedule. In practice, most contractors run annual PPE refreshers because the knowledge is perishable and hazards evolve as the work progresses. Every training event should be documented with the date, the topics covered, the trainer, and the worker's demonstrated competency, so qualification can be proven during an inspection or after an incident. New hires should never work in a PPE-required area until a competent person has verified they can inspect and correctly wear the equipment.

How often should PPE be inspected?

PPE should be inspected before each use and removed from service the moment damage appears. Hard hats need a look for cracks, dents, gouges, and UV degradation, along with a check that the suspension has not exceeded its service life; safety glasses and face shields for scratches and cracks that impair vision or integrity; gloves for tears, chemical breakthrough, and wear; and respirators for a valid fit and intact valves and straps before every use. Beyond the daily check, employers should run documented periodic inspections — weekly reviews of the crew's gear and monthly audits of inventory, expiration dates, and issuance records — to catch equipment nearing the end of its life. A written inspection log turns these checks into evidence of a functioning program, which matters for OSHA compliance and for defending against liability after an incident. Photo-based tools such as OSHA Scan make it practical to capture and timestamp these inspections consistently across every crew and site.

When should work be stopped over a PPE gap?

Stop work immediately whenever a worker faces a recognized hazard without the correct, undamaged PPE — no hard hat in a struck-by zone, no rated eye protection during grinding or cutting, no respirator or fit test where airborne contaminants are present, or hearing protection missing in high-noise operations. Work should also stop when PPE is found damaged, expired, or wrong for the exposure, or when a written hazard assessment for the task has never been completed. Every worker has the right and the responsibility to stop a job that feels unsafe without fear of reprisal, and supervisors should treat a PPE gap as a hard stop rather than a warning. The cost of pausing to retrieve or replace equipment is trivial compared with a permanent eye injury, hearing loss, or head trauma, and a documented stop-work culture is one of the clearest signals to general contractors and insurers that a company manages risk seriously.

PPE gaps: the last line of defense, and the one most often missing

Head, eye, hearing, respiratory, hand, and foot protection done right

Personal protective equipment is the final barrier between a worker and an injury, yet missing, wrong, or ill-fitting PPE remains one of the most common findings on any job site. PPE sits at the bottom of the hierarchy of controls for a reason — it does nothing to remove the hazard, it only reduces the harm if everything else fails. OSHA Scan reads a single photo and flags the workers who are unprotected before the moment they need protection arrives.

A PPE gap is any situation where a worker faces a recognized hazard without the correct protective equipment, or with equipment that is damaged, expired, wrong for the exposure, or simply not worn. This spans the full range of PPE: head protection (hard hats) against falling and struck-by objects, eye and face protection (safety glasses, goggles, face shields) against flying particles and splashes, hearing protection against damaging noise, respiratory protection against dusts, fumes, and vapors, high-visibility clothing around traffic and equipment, hand protection (gloves) matched to cuts, chemicals, or heat, and foot protection against crushing, punctures, and slips.
PPE is deliberately the last line of defense in the hierarchy of controls — after elimination, substitution, engineering controls, and administrative controls. It does not remove the hazard; it only lowers the severity of an injury if every other control fails. That is why relying on PPE alone is fragile: a moment of forgetfulness, a poor fit, or a worn-out strap can be the difference between going home and going to the hospital.
OSHA places the burden squarely on the employer. Under the general PPE rule the employer must assess the workplace for hazards, document that assessment in writing, select equipment that fits each affected worker, provide it (at no cost for most required PPE), train workers on how to use and maintain it, and enforce its use. A missing written hazard assessment is itself a citable violation, even when the right gear happens to be on the shelf.

Where does PPE fall in the hierarchy of controls?

PPE is the last line of defense, sitting below elimination, substitution, engineering controls, and administrative controls. It does not remove the hazard — it only reduces the severity of an injury if the other controls fail. That is why OSHA expects employers to control hazards at the source first and treat PPE as a supplement, not a substitute.

Does the employer have to pay for PPE?

In most cases, yes. OSHA requires employers to provide required PPE at no cost to the worker, including hard hats, safety glasses, hearing protection, respirators, and most gloves and footwear. Narrow exceptions exist — such as ordinary non-specialty prescription safety eyewear allowed off-site and certain everyday footwear — but the general rule is employer-paid.

What is a written hazard assessment?

It is the employer's documented evaluation of each work area and task to identify hazards that require PPE. Under 29 CFR 1910.132 the assessment must be certified in writing, identifying the workplace evaluated, the person certifying it, and the date. Skipping the written certification is itself a citable violation even when the correct PPE is present.

When are hard hats required?

Hard hats are required wherever there is a danger of head injury from impact, falling or flying objects, or electrical shock and burns. They must meet the applicable ANSI/ISEA Z89.1 standard. On active construction sites with overhead work or struck-by hazards, that generally means hard hats are worn at all times in the work area.
