When the p>ertincnt factors have been considered and a decision has been reached to proceed with a rescue, all reasonable protective measures should be taken by rescuers. Response personnel should use positive pressure. Self Contained Breathing Apparatus (SCBA) and aveiilable protective clothing while working as quickly as possible to minimize their exposure to the toxic materials. 

Health Hazards Information - Recommended Personal Protective Equipment Chemical safety goggles and full face shield, self-contained breathing apparatus (SCBA), positive pressure hose mask, airline mask rubber safety shoes, chemical protective clothing Symptoms Following Exposure Inhalation causes irritation of nose and throat, a feeling of pressure in the chest, and shortness of breath. Nausea... 

Use a self-contained breathing apparatus (SCBA). Air purifying respirators (APRs) are not recommended for use in an arsine atmosphere because of poor warning properties and the unknown effectiveness of sorbents used in the filters.

Personal Protection Protective clothing must be used as well as protection for the respiratory tract by using a mask with biological filters or self-contained breathing apparatus (SCBA) with positive pressure, at least until you know the specific threat(s). Also, Time/Distance/Shielding. 

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).

Level A protection 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, coveralls, hard hat, and self-contained (positive pressure) and self-contained breathing apparatus (SCBA). 

Personal Protective Equipment Phosgene is a severe respiratory tract and skin irritant, and contact with the liquid will cause frostbite. Respiratory protection requires positive-pressure-demand, self-contained breathing apparatus (SCBA), while skin protection requires chemical-protective clothing since phosgene gas can cause skin irritation and burns. NIOSH recommends protective suits from Responder (Kappler Co.), Tychem 10000 TM (DuPont Co.) or Teflon (DuPont Co.).
