NIOSH-approved self-contained

In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode... 

Caution Contact with arsine vapor can be fatal. Do not breathe the fumes If inhalation is a possibility, hold breath until respiratory mask is donned. Firefighters should wear full protective clothing and respiratory protection during both fire-fighting and rescue (positive pressure, full face, NIOSH-approved self-contained breathing apparatus/SCBA shall be worn). 

Respiratory protection is required. Positive pressure, full facepiece, NIOSH-approved self-contained breathing apparatus (SCBA) will be worn where there is danger of oxygen deficiency and when directed by the fire chief or chemical accident/incident (CAI) operations officer. In cases where firefighters are responding to a chemical accident/incident for rescue/reconnaissance purposes vice firefighting, they will wear appropriate levels of protective clothing (see Section 8). 

CFR1910.134 4.2.14 Where toxic gases are stored, a minimimi of two NIOSH approved self-contained breathing apparatus (SCBAs) shall be kept available at all times for use in upset conditions. They shall be cleaned and disinfected after each use, properly maintained and stored, inspected at least monthly, and checked for proper function before and after each use. 

The material is not considered a fire hazard, although flammable ammonia gas may be released in a fire. The chemical may explode if mixed with oxidizers, such as potassium nitrate, potassium nitrite, and potassium chlorate. Use any means suitable for extinguishing surrounding fire. Water spray may be used to keep fire-exposed containers cool. In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode. 

CFR1910.120(q)(3)(x) 4.3.10 When deemed necessary by the safety officer for meeting the tasks at hand, approved self-contained compressed air breathing apparatus may be used with approved cylinders from other approved self-contained compressed air breathing apparatus provided that such cylinders are of the same capacity and pressure rating. All compressed air cylinders used with self-contained breathing apparatus shall meet U.S. Department of Transportation (USDOT) and National Institute for Occupational Safety and Health (NIOSH) criteria. 

A NIOSH/MSHA-approved self-contained breathing apparatus or combination air-supplied/SCBA respirator should be provided for use in the event of an accidental leak or when atmospheric concentration is greater than 5 ppm (20 mg/m ). 

Personal Protective Equipment Respiratory protection is required (positive pressure, full face piece, NIOSH-approved SCBA will be worn). When response personnel respond to handle rescue or reconnaissance, they will wear Level A protection that should be worn when the highest level of respiratory, skin, eye, and mucous membrane protection is needed. This level consists of a fully-encapsulated, vapor-tight, chemical-resistant suit, chemical-resistant boots with steel toe and shank, chemical-resistant inner/outer gloves (butyl rubber glove M3 and M4 Norton, chemical protective glove set), coveralls, hard hat, and self-contained (positive pressure) breathing apparatus (SCBA). 

Positive pressure, fuU face-piece self-contained breathing apparatus (SCBA), or positive pressure supplied air respirator with escape SCBA, approved by the National Institute for Occupational Safety and Health (NIOSH)... 

PERSONAL PROTECTION Wear solvent-resistant gloves and clothing Teflon is recommended as a protective material wear splash resistant goggles enclose operations and use local exhaust ventilation at site of chemical release use a NIOSH approved full facepiece respirator with an organic cartridge where the potential exists for exposure over 10 ppm where the potential for high exposure exists, use self-contained breathing apparatus.
