PPE Selection & Proper Use — Toolbox Talk Guide

The Hazard Assessment: Foundation of Correct PPE Selection

OSHA 1910.132(d) and 1926.95(a) require employers to assess the workplace to determine if hazards are present, or likely to be present, that necessitate the use of PPE. This assessment must be performed by a knowledgeable person and documented in a written certification that identifies the workplace evaluated, the person certifying the assessment, the date of the assessment, and the document as a certification of hazard assessment. A generic PPE policy that lists 'hard hat, safety glasses, and steel-toed boots required at all times' without a task-specific hazard analysis does not constitute a compliant written assessment.

The hazard assessment must consider each body area at risk for each task: the head (impact, penetration, electrical contact, chemical splash), eyes and face (flying particles, chemical splash, UV radiation, arc flash), ears (noise exposure above 85 dBA TWA), respiratory system (airborne contaminants above PELs), hands (cuts, abrasion, chemical permeation, electrical, heat), feet (impact, compression, puncture, electrical, chemical), and the body as a whole (fall, chemical immersion, arc flash, heat). Different tasks at the same work location may require entirely different PPE configurations — a worker who cuts concrete in the morning and pours epoxy coatings in the afternoon faces different hazards requiring different gloves, respiratory protection, and eye protection for each task.

The hazard assessment must be repeated whenever work processes, materials, or equipment change. A PPE assessment performed during the design phase of a project or at the beginning of a contract may not remain valid as work progresses and new hazards are introduced. Supervisors must have the authority and the expectation to update PPE requirements in the field when new tasks or hazards arise, without waiting for a formal written revision — but the written assessment must be updated to reflect current conditions.

Head, Eye, Face, and Hearing Protection

Hard hats must comply with ANSI/ISEA Z89.1 and be selected for the appropriate class. Type I hard hats protect the top of the head only; Type II hard hats protect the top and sides. Class E (Electrical) hard hats are tested to 20,000 volts; Class G (General) to 2,200 volts; Class C (Conductive) provides no electrical protection. The class and type must match the hazard — a Class G hard hat worn by a worker near unguarded 15kV power lines does not provide adequate protection. Hard hats must be inspected before each use for cracks, dents, and suspension damage; a hard hat that has sustained an impact must be replaced even if no visible damage is apparent, because the shell absorbs energy by deforming internally.

Eye and face protection must be selected for the specific hazard per ANSI/ISEA Z87.1. Safety glasses with side shields protect against flying particles and light splash; they do not protect against chemical splash or heavy spray. Chemical splash goggles — fully sealed against the face — are required when liquid chemicals or large particle streams can reach the eye from any angle. Face shields provide protection for the full face but do not replace primary eye protection — safety glasses or goggles must be worn under a face shield. Welding filters must be selected by shade number appropriate to the welding process: shade 10 for SMAW up to 400A, shade 12–13 for heavier amperages. Arc flash face shields must carry an arc rating in cal/cm² matched to the arc flash hazard analysis.

Hearing protection is required by OSHA 1910.95 when noise exposures reach or exceed 85 dBA as an 8-hour TWA — the action level that triggers the hearing conservation program — and is mandatory at or above 90 dBA (the PEL). The Noise Reduction Rating (NRR) on hearing protection packaging is a laboratory value that overestimates real-world protection; NIOSH recommends derating NRR values by 50% for earplugs and 25% for earmuffs to estimate field performance. A properly inserted foam earplug with NRR 33 provides approximately 16 dB of real-world attenuation (33 − 7, divided by 2). Workers must be trained on proper earplug insertion — a rolled earplug inserted only partway into the ear canal provides a fraction of its rated protection.

Hand and Foot Protection Selection

Glove selection is one of the most task-specific PPE decisions on any job site. The correct glove for cutting silicone tubing (cut-resistant, ANSI/ISEA 105 cut level A4 or higher) is very different from the correct glove for handling acetone (chemical-resistant nitrile or neoprene) or for electrical work (rubber insulating gloves, voltage-rated, with leather protectors). A single 'work glove' worn for every task on a job site is rarely the correct selection for any of them. OSHA 1910.138 requires that protective equipment for hands shall be selected on the basis of the performance characteristics of the glove relative to the task to be performed.

Cut-resistant gloves under ANSI/ISEA 105 are rated from A1 (lightest protection) through A9 (heaviest protection) based on grams of cutting force required to cut through the material. For tasks involving glass handling, metal edge work, or blade use, cut levels A4–A6 are commonly specified on construction sites. Chemical-resistant gloves must be matched to the specific chemical by permeation testing data from the manufacturer — a glove that is resistant to one solvent may not be resistant to a structurally different solvent. Glove breakthrough time — the time from initial chemical contact to measurable permeation through the glove — must exceed the expected contact duration for the task.

Foot protection under ASTM F2413 encompasses several protection ratings that must match the hazard: impact protection (I/75 or I/50, indicating the joule rating of the drop weight test), compression protection (C/75 or C/50, for rolling load resistance), metatarsal protection (Mt, for impact protection over the metatarsal bones above the toe cap), puncture resistance (PR, for nail penetration through the sole), and electrical hazard (EH, for secondary protection against open electrical circuits). Most construction safety boots carry I/75, C/75, and EH ratings as a baseline. Workers whose tasks involve molten metal splash, chainsaw use, or specific chemical exposure need footwear with additional protection ratings beyond the construction baseline.

Proper Fit, Donning, and Doffing Procedures

PPE that does not fit correctly does not protect correctly. An oversized hard hat that rocks forward over the eyes during a forward lean does not protect the back of the head from a falling object behind the worker. Safety glasses that gap at the temples provide an unimpeded path for flying particles. Gloves two sizes too large allow chemical-soaked material to contact the wrist and lower arm when the glove deflects. OSHA requires under 1910.132(d)(1)(ii) that PPE be selected in appropriate sizes to fit employees properly. Employers must stock multiple sizes and must not issue PPE that does not fit and expect the worker to 'make it work.'

Donning and doffing procedures are particularly critical for PPE used with chemical hazards. Chemical-resistant PPE that becomes contaminated on its outer surface must be doffed without contaminating the worker's skin or clothing — doffing an improperly donned chemical suit or contaminated gloves is one of the leading causes of chemical skin exposure in operations where the suit was otherwise functioning correctly. The correct doffing sequence for chemical gloves: remove the first glove by peeling it off from the outside, holding it in the gloved hand; then slide two fingers of the bare hand inside the cuff of the second glove and peel it off from the inside, enclosing the first glove inside the second. This technique ensures the contaminated outer surfaces never contact bare skin.

Disposable PPE — nitrile exam gloves, N95 respirators, chemical splash goggles, and Tyvek coveralls — must not be reused between tasks or between workers. Contamination on the outer surface of disposable PPE represents a direct exposure pathway when the worker removes and reuses the item. Workers must understand that 'single use' means single use, and that the cost of disposable PPE replacement is far less than the cost of a chemical exposure incident. A stockpile of disposable PPE at each work area eliminates the temptation to reuse items that have become contaminated.

Inspection, Maintenance, and Employer Responsibilities

OSHA 1910.132(a) and 1926.95(a) require that PPE be maintained in a sanitary and reliable condition. Inspection before each use is required for PPE that could fail in a way that exposes the worker to the hazard it was meant to prevent — a torn chemical-resistant glove, a cracked hard hat shell, fogged or scratched safety glasses that impair vision, or an arc-rated garment with a burn hole that reduces its effective insulation value. Workers must be trained to inspect their PPE and must have a clear path to remove defective PPE from service and obtain a replacement without administrative barriers.

Storage of PPE significantly affects its service life and continued effectiveness. Hard hats must be stored away from UV exposure (sunlight degrades polycarbonate and high-density polyethylene shells), extreme heat, and chemical solvents. Rubber insulating gloves must be stored rolled and away from ozone sources (electric motors, UV lights, and fluorescent lights generate ozone that degrades rubber). Arc-rated garments must not be laundered with chlorine bleach, fabric softener, or starching agents — these treatments can reduce the arc rating of the fabric. Chemical-resistant gloves and suits must be rinsed with water after use, inspected for degradation, and stored away from UV and ozone.

OSHA 1910.132(h) and 1926.95 require that employers provide PPE at no cost to employees with specific exceptions for everyday clothing, non-specialty safety-toe footwear, and logging boots. The employer must also pay for replacement PPE — a worker whose gloves have been destroyed by chemical exposure or whose hard hat shell was cracked by a falling object must receive replacement PPE at no charge and must not be expected to work without it or to purchase their own. Charging workers for PPE through payroll deduction, requiring deposits, or penalizing workers financially for lost or damaged PPE violates OSHA's no-cost provision and creates a disincentive for workers to report and replace defective equipment.

✅ Key Takeaways

• →The hazard assessment must be written and task-specific — a generic 'hard hat and boots at all times' policy does not constitute a compliant PPE assessment under OSHA 1910.132(d).
• →Type II Class E hard hats protect top and sides and are rated to 20,000V; Class G protects only to 2,200V — match the class to the electrical exposure level.
• →Glove selection must be based on the specific chemical or mechanical hazard; a glove resistant to one solvent may have no resistance to a chemically different solvent.
• →Doff contaminated chemical gloves using the peel-and-tuck technique — the contaminated outer surfaces must never contact bare skin during removal.
• →Hard hats must be replaced after any impact even with no visible damage; arc-rated garments must never be laundered with bleach or fabric softener, which degrade arc protection.
• →Employers must provide PPE at no cost and must provide replacements at no cost — financial penalties or payroll deductions for lost PPE are prohibited and discourage workers from replacing defective equipment.
