16.2 Respiratory Protection, PPE, and Hygiene Facilities

Respirators supplement controls; they do not retire the 1910.134 program

Quick Answer: When 1926.62 requires a respirator, the employer provides a NIOSH-approved respirator under a 29 CFR 1910.134 program — medical evaluation, fit test, training, and the other incorporated 1910.134 paragraphs. Use HEPA filters (N100 / R100 / P100 on non-powered air-purifying respirators; HEPA on PAPRs). A half-mask air-purifying respirator has a typical assigned protection factor (APF) of 10, which matches Group 1's assumed band of >PEL but ≤10× PEL (500 µg/m³). Group 2 assumed >500 µg/m³ needs a higher APF (full facepiece APF 50 or a PAPR, not a half-mask). Provide a PAPR when an employee chooses one and it will provide adequate protection. Protective clothing, change areas, handwashing, showers where feasible, and no food, beverage, tobacco, or cosmetics apply where exposure is above the PEL without regard to respirators. Do not take lead home on clothes. Chapter 10's three-stage decon is how you build that hygiene; 745.227 does not name the three rooms.

Section 16.1 set the air numbers and the trigger-task bands. This section is what the employee actually wears and where the employee actually eats. The exam bait is a dust mask from the hardware aisle, a half-mask on a needle gun without collection, lunch on the drop cloth “because we have respirators,” and sending the crew home in dirty coveralls.

When a respirator is required — and what program it rides on

1926.62(f)(1) requires an appropriate respirator during: periods when exposure exceeds the PEL; operations where engineering and work-practice controls are not sufficient to reach the PEL; periods when an employee requests a respirator; and interim protection on (d)(2) trigger tasks.

The program is not “the box says NIOSH.” (f)(2) incorporates 1910.134(b) through (d) (except (d)(1)(iii)) and (f) through (m). In field language that means: written program, medical evaluation before fit testing, annual fit test for tight-fitting facepieces, training, inspection, storage, and a change-out plan. If an employee has breathing difficulty during fit testing or use, (f)(2)(ii) sends that employee to the medical-exam track in (j)(3)(i)(B).

(f)(3) selection rules that show up on this exam:

• Select respirators using 1910.134 Table 1 APFs.
• Provide a full facepiece instead of a half-mask when lead aerosols may cause eye or skin irritation at the use concentrations.
• Provide HEPA filters for powered and non-powered air-purifying respirators.
• Provide a PAPR when the employee chooses one and it will provide adequate protection.

Surgical masks, one-strap nuisance dust masks, and “the N95 we use for drywall” are not a lead respirator. Lead needs a 100-series / HEPA filter on an air-purifying respirator, on a facepiece that was fit-tested, on a person who was medically evaluated.

APF table — match the assumed band to the facepiece

Maximum use concentration for a respirator = PEL × APF, provided the device is NIOSH-approved, the program is real, and the assumed or measured concentration is in that band.

Group 1 assumed ≤500 µg/m³ is why accredited courses still say “half-mask HEPA” for heat guns, manual scrape, and shrouded power tools until the cassette says otherwise. Group 2 assumed >500 µg/m³ is why a half-mask is the wrong answer for unshrouded power-tool cleaning, rivet busting, lead burning, and moving a blast enclosure: APF 10 cannot cover a number above 500. Select a respirator whose APF covers that assumed exposure — typically APF 50 (full facepiece or PAPR) or better. Group 3 assumed >2,500 µg/m³ is above the MUC of an APF-50 device; blasting, welding, cutting, and torch burning need a higher-APF system (and torch burning is separately prohibited by EPA on LBP abatement).

Worked example — employee asks for a PAPR on Group 1 wet scrape. Unprotected monitoring later comes back at 90 µg/m³. A half-mask APF 10 would be adequate on that number (MUC 500). The employee still gets the PAPR if it is adequate, because (f)(3)(ii) is a choice rule, not a “only if the half-mask failed” rule. Comfort, facial hair that prevents a tight seal (which is a disqualification for a tight-fitting facepiece, not a reason to skip protection), heat, and medical restrictions are why the PAPR sentence exists.

Clothing: weekly, daily above 200, never shaken out at home

1926.62(g) — provide at no cost and assure use of clothing that keeps lead off the employee and the employee's garments when exposure is above the PEL without regard to respirators, when lead compounds may irritate skin or eyes, and as interim protection on trigger tasks. Typical issue: coveralls or similar full-body clothing; gloves, hats, and shoes or disposable shoe covers; face shields or vented goggles as needed.

Employees shall not leave the workplace wearing the protective clothing or equipment required during the shift. That is the take-home rule in one sentence. Chapter 4 already told you a toddler at home is an ingestion pathway. This section is the OSHA citation that makes that pathway an employer failure.

Hygiene: the respirator does not make the sandwich legal

1926.62(i)(1) — in areas where employees are exposed above the PEL without regard to the use of respirators, food or beverage is not present or consumed, tobacco products are not present or used, and cosmetics are not applied. The half-mask on the chin during lunch is not a loophole. Unprotected exposure above 50 µg/m³ is the trigger, not “whether anyone is hungry.”

Showers are where feasible, not “never on residential work.” A 40-unit gut with a trailer on the lot can have showers. A one-bathroom occupied unit may not; then hand-and-face washing at shift end is not optional. Do not tell the exam that residential abatement has no hygiene duties because a three-stage shower trailer would not fit in the hallway.

Overlap with Chapter 10 — three rooms that implement (i), not a 745.227 sentence

Chapter 10.3 taught the accredited dirty / shower / clean layout: enter through the clean room, work dirty, HEPA-vacuum and remove PPE in the equipment room, shower when that stage exists, dress in street clothes in the clean room, waste on a separate load-out path. 745.227 does not name those three rooms. 1926.62(i) and (g) are why the rooms exist when exposures warrant: change areas, no take-home clothing, no lunch in the over-PEL space, handwashing, showers where feasible.

The exam will offer two wrong exits from that overlap. One: “EPA requires a three-stage decon in 745.227, so OSHA hygiene is redundant.” False — EPA never wrote the three rooms. Two: “EPA is silent, so we eat in the contained bedroom and drive home in Tyveks.” Also false — OSHA still cites the sandwich and the take-home clothes. Build the Chapter 10 flow so that (i) and (g) are physically true.

1926.62(m) warning signs in each work area where employee exposure is above the PEL: DANGER / LEAD / MAY DAMAGE FERTILITY OR THE UNBORN CHILD / CAUSES DAMAGE TO THE CENTRAL NERVOUS SYSTEM / DO NOT EAT, DRINK OR SMOKE IN THIS AREA. HUD Chapter 8 entry signs for occupants (Chapter 10.1) are a second layer. Neither is a substitute for a change area.

Worked example — occupied unit, Group 1 windows. Containment from Chapter 10 is up. Crew in half-mask P100s, coveralls, shoe covers. Unprotected assessment is still pending, so treat as over the PEL. Hygiene that matches (i): no coffee on the sill; change area at the dirty end of the decon with separate street-clothes storage; HEPA off the coveralls before they come off; hands and face washed before anyone cracks a lunch box on the clean side; coveralls bagged, not worn to the truck. Skipping the change area because “it is only windows” is how take-home dust starts.

Supervisor decision test. (1) Is there a 1910.134 program, or just a box of half-masks? (2) Does the APF cover the assumed or measured unprotected concentration? (3) Did the employee who asked for a PAPR get one if it is adequate? (4) Are clothing, change areas, and no-eating rules keyed off exposure without the respirator? (5) Would a child at the worker's house meet that worker's dirty sleeves at 4 p.m.?
