(a) Permissible practice.
(1) In the control of those occupational
						diseases caused by breathing air contaminated with harmful dusts, fogs, fumes,
						mists, gases, smokes, sprays, or vapors, the primary objective shall be to
						prevent atmospheric contamination. This shall be accomplished as far as
						feasible by accepted engineering control measures (for example, enclosure or
						confinement of the operation, general and local ventilation, and substitution
						of less toxic materials). When effective engineering controls are not feasible,
						or while they are being instituted, appropriate respirators shall be used
						pursuant to this section.
(2)
						Respirators shall be provided by the employer when such equipment is necessary
						to protect the health of the employee. The employer shall provide the
						respirators which are applicable and suitable for the purpose intended. The
						employer shall be responsible for the establishment and maintenance of a
						respiratory protection program which shall include the requirements outlined in
						subsection (c).

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
The individual who uses a tight-fitting respirator is
						  to perform a user seal check to ensure that an adequate seal is achieved each
						  time the respirator is put on. Either the positive and negative pressure checks
						  listed in this appendix, or the respirator manufacturer's recommended user seal
						  check method shall be used. User seal checks are not substitutes for
						  qualitative or quantitative fit tests.
I. Facepiece Positive and/or Negative Pressure
						  Checks.
A. Positive pressure check. Close off the exhalation
						  valve and exhale gently into the facepiece. The face fit is considered
						  satisfactory if a slight positive pressure can be built up inside the facepiece
						  without any evidence of outward leakage of air at the seal. For most
						  respirators this method of leak testing requires the wearer to first remove the
						  exhalation valve cover before closing off the exhalation valve and then
						  carefully replacing it after the test.
B. Negative pressure check. Close off the inlet opening
						  of the canister or cartridge(s) by covering with the palm of the hand(s) or by
						  replacing the filter seal(s), inhale gently so that the facepiece collapses
						  slightly, and hold the breath for ten seconds. The design of the inlet opening
						  of some cartridges cannot be effectively covered with the palm of the hand. The
						  test can be performed by covering the inlet opening of the cartridge with a
						  thin latex or nitrile glove. If the facepiece remains in its slightly collapsed
						  condition and no inward leakage of air is detected, the tightness of the
						  respirator is considered satisfactory.
II. Manufacturer's Recommended User Seal Check
						  Procedures. The respirator manufacturer's recommended procedures for performing
						  a user seal check may be used instead of the positive and/or negative pressure
						  check procedures provided that the employer demonstrates that the
						  manufacturer's procedures are equally effective.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Respirators are an effective method of protection
						  against designated hazards when properly selected and worn. Respirator use is
						  encouraged even when exposures are below the exposure limit, to provide an
						  additional level of comfort and protection for workers. However, if a
						  respirator is used improperly or not kept clean, the respirator itself can
						  become a hazard to the worker. Sometimes, workers may wear respirators to avoid
						  exposures to hazards, even if the amount of hazardous substance does not exceed
						  the limits set by OSHA standards. If your employer provides respirators for
						  your voluntary use, or if you provide your own respirator, you need to take
						  certain precautions to be sure that the respirator itself does not present a
						  hazard.
You should do the following:
1. Read and heed all instructions provided by the
						  manufacturer on use, maintenance, cleaning and care, and warnings regarding the
						  respirators limitations.
2. Choose respirators certified for use to protect
						  against the contaminant of concern. NIOSH, the National Institute for
						  Occupational Safety and Health of the U.S. Department of Health and Human
						  Services, certifies respirators. A label or statement of certification should
						  appear on the respirator or respirator packaging. It will tell you what the
						  respirator is designed for and how much it will protect you.
3. Do not wear your respirator into atmospheres
						  containing contaminants for which your respirator is not designated to protect
						  against. For example, a respirator designed to filter dust particles will not
						  protect you against gases, vapors or very small solid particles of fumes or
						  smoke.
4. Keep track of your respirator so that you do not
						  mistakenly use someone else's respirator.

						  adverse effect. Because of some variation in individual susceptibility, an
						  occasional worker may suffer discomfort, aggravation of a pre-existing
						  condition, or occupational disease upon exposure to concentrations even below
						  the values specified in these tables. The exposure limits established by this
						  section reflect current medical opinion and industrial hygiene practice, doubts
						  being resolved on the side of safety, and are intended to be used in accordance
						  with good industrial hygiene practice by qualified persons. The division
						  recognizes the need for almost continuous review of these concentration limits

						distance, or by partitions, dikes, berms, secondary containment or otherwise,
						so as to preclude accidental contact between them.
NOTE: Some typical examples of such incompatible
						  substances are: Mineral acids and oxidizing agents; mineral acids and cyanides;
						  oxidizing agents and combustible materials; acids and alkalis.
(b) Hazardous substances shall be stored in
						containers, such as those approved by the U.S. Department of Transportation
						(DOT), which are chemically inert to and appropriate for the type and quantity
						of the hazardous substance.
(c)
						Containers of hazardous substances shall not be stored in such locations or
						manner as to result in physical damage to, or deterioration of, the container.
						Containers shall not be stored where they are exposed to heat sufficient to
						rupture the containers or to cause leakage.
(d) Containers used to package a substance
						which gives off toxic, poisonous, corrosive, asphyxiant, suffocant, or
						anesthetic fumes, gases, or vapors in hazardous amounts (e.g., fuming sulfuric
						acid, hydrofluoric acid, nitrous oxide, chlorine, or other compressed or
						liquefied toxic gases) shall not be stored locations where it could be
						reasonably anticipated that employees would be exposed. This requirement shall
						not apply to small quantities of such materials kept in closed containers, or
						to tank cars or trucks.
