SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION

RESPIRATORY PROTECTION:

Respiratory protection approved by NIOSH/MSHA for ammonia must be used when

exposure limits are exceeded. Whether a chemical cartridge respirator or a self-contained breathing apparatus is sufficient for effective

respiratory protection depends on the type and magnitude of exposure.

EYE PROTECTION:

Chemical splash goggles, approved for use with ammonia, must be worn to prevent eye contact with liquid or vapor.

A face shield should be used for increased protection from contact with liquid.

VENTILATION:

Local positive pressure and/or exhaust ventilation should be used to reduce vapor concentrations in confined spaces.

Ammonia vapor, being lighter than air, can be expected to dissipate to the upper atmosphere. Ammonia concentrations may also be

reduced by the use of an appropriate absorbent or reactant material.

OTHER EQUIPMENT:

Emergency eye wash stations and deluge safety showers must be available in the work area. Post a list of

emergency response contacts and telephone numbers.

SECTION 10: STABILITY AND REACTIVITY

STABILITY:

Material generally considered stable. However, heating above ambient temperatures causes the vapor pressure of ammonia

to increase rapidly.

INCOMPATIBILITY (Materials to Avoid):

Ammonia can react violently with strong acids. Under certain conditions, ammonia reacts

with bromine, chlorine, fluorine or iodine to form compounds which explode spontaneously. Reactions of ammonia with gold, silver or
mercury to form explosive fulminate-like compounds have been reported.

HAZARDOUS DECOMPOSITION PRODUCTS:

Hydrogen on heating to over 850



F. The decomposition temperature may be lowered

to 575



F by contact with certain metals such as nickel.

HAZARDOUS POLYMERIZATION:

Will not occur.

CONDITIONS TO AVOID:

Not applicable.

SECTION 11: TOXICOLOGICAL INFORMATION

Ammonia is a strong alkali and readily damages all body tissues. Ammonia is not a cumulative metabolic poison.

Waterfowl Toxicity:

120 ppm

Biochemical Oxygen Demand:

Not pertinent

Food Chain Concentration Potential: None

SECTION 13: DISPOSAL CONSIDERATIONS

Recover ammonia if feasible. Otherwise, let ammonia evaporate if appropriate. Only personnel experienced in ammonia spills should add

water to liquid ammonia. Dispose of diluted ammonia as a fertilizer or in an industrial process. For Hazardous Waste Regulations call

1-800-424-9346, the RCRA Hotline.
