Ammonia

CAS RN: 7664-41-7

Protective Equipment / Clothing

Eye/face protection: Tightly fitting safety goggles. Faceshield (8-inch minimum). Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protection: Handle with gloves.
Body Protection: Complete suit protecting against chemicals. Flame retardant antistatic protective clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.
Respiratory protection: Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multipurpose combination (US) or type AXBEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
Ammonia: Chemical protective clothing composed of butyl rubber, natural rubber, neoprene, nitrile rubber, and polyvinyl chloride may be used since data suggest that breakthrough times are approximately an hour or more. Vitron is not recommended for use since data (usually from immersion tests) suggest that breakthrough times are less than one hour.
Wear appropriate personal protective clothing to prevent skin contact.
Wear appropriate eye protection to prevent eye contact.
Eyewash fountains should be provided in areas where there is any possibility that workers could be exposed to the substance; this is irrespective of the recommendation involving the wearing of eye protection. />10%/
Facilities for quickly drenching the body should be provided within the immediate work area for emergency use where there is a possibility of exposure. [Note: It is intended that these facilities provide a sufficient quantity or flow of water to quickly remove the substance from any body areas likely to be exposed. The actual determination of what constitutes an adequate quick drench facility depends on the specific circumstances. In certain instances, a deluge shower should be readily available, whereas in others, the availability of water from a sink or hose could be considered adequate.] />10%/
First Responders should use a NIOSH-certified Chemical, Biological, Radiological, Nuclear (CBRN) Self Contained Breathing Apparatus (SCBA) with a Level A protective suit when entering an area with an unknown contaminant or when entering an area where the concentration of the contaminant is unknown. Level A protection should be used until monitoring results confirm the contaminant and the concentration of the contaminant.
Respirator Recommendations: Up to 250 ppm:
Assigned Protection Factor (APF) Respirator Recommendations
APF = 10 Any chemical cartridge respirator with cartridge(s) providing protection against the compound of concern. Substance reported to cause eye irritation or damage; may require eye protection.

APF = 50 Any supplied-air respirator with a full facepiece.
Respirator Recommendations: Emergency or planned entry into unknown concentrations or IDLH conditions:
Assigned Protection Factor (APF) Respirator Recommendations
APF = 10,000 Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode.
APF = 10,000 Any supplied-air respirator that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained positive-pressure breathing apparatus.
Respirator Recommendations: Escape:
Assigned Protection Factor (APF) Respirator Recommendations
APF = 50 Any air-purifying, full facepiece respirator (gas mask) with a chin-style, front- or back-mounted canister providing protection against the compound of concern. /Any appropriate escape-type, self-contained breathing apparatus.
Eye protection, respiratory apparatus, and cotton clothing. Be sure equipment is not aluminum, copper, lead, or tin. Protective clothing over a cotton layer is recommended.
