# What are unintentional release measures for hydrogen sulfide? (cont.) ## What Personal Protective Equipment (PPE) is needed when working with hydrogen sulfide? (cont.) Up to 100 ppm: (APF = 10) Any supplied-air respirator*. (APF = 25) Any powered, air-purifying respirator with cartridge(s) providing protection against hydrogen sulfide. (APF = 50) Any air-purifying, full-facepiece respirator (gas mask) with a chin-style, front- or back-mounted canister providing protection against hydrogen sulfide or any self-contained breathing apparatus with a full facepiece. *Reported to cause eye irritation or damage; may require eye protection. APF = Assigned Protection Factor Recommendations apply only to National Institute for Occupational Safety and Health (NIOSH) approved respirators. Refer to the NIOSH Pocket Guide to Chemical Hazards for more information.

# OSHA QUICK CARD™ # Protect Yourself Respirators Respiratory protection must be worn whenever you are working in a hazardous atmosphere. The appropriate respi- rator will depend on the contaminant(s) to which you are exposed and the protection factor (PF) required. Required res- pirators must be NIOSH-approved and medical evaluation and training must be provided before use. Single-strap dust masks are usually not NIOSH-approved. They must not be used to protect from hazardous atmospheres. However, they may be useful in providing comfort from pollen or other allergens. Approved filtering facepieces (dust masks) can be used for dust, mists, welding fumes, etc. They do not provide protection from gases or vapors. DO NOT USE FOR ASBESTOS OR LEAD; instead, select from the respirators below. Half-face respirators can be used for protec- tion against most vapors, acid gases, dust or welding fumes. Cartridges/filters must match contaminant(s) and be changed periodically. Full-face respirators are more protective than half-face respirators. They can also be used for protection against most vapors, acid gases, dust or welding fumes. The face-shield pro- tects face and eyes from irritants and con- taminants. Cartridges/filters must match con- taminant(s) and be changed periodically. Loose-fitting powered-air-purifying respirators (PAPR) offer breathing comfort from a bat- tery-powered fan which pulls air through fil- ters and circulates air throughout helmet/ hood. They can be worn by most workers who have beards. Cartridges/filters must match contaminant(s) and be changed periodically. A Self-Contained Breathing Apparatus (SCBA) is used for entry and escape from atmospheres that are considered immediate- ly dangerous to life and health (IDLH) or oxy- gen deficient. They use their own air tank. For more complete information: Occupational OSHA Safety and Health Administration U.S. Department of Labor www.osha.gov (800) 321-OSHA OSHA 3280-10N-05
