Section III - Hazard Identification
Inhalation of 500 PPM Ammonia considered immediately dangerous to life and health
Potential Acute Health Effects:
Eyes and Skin: EYES: Liquid: Intensely irritating; in extreme, corneal ulceration or blindness.
SKIN: Liquid: Corrosive burns or blister formation. Gas: Irritates moist skin.
Ammonia vapors are highly irritating to throat at approximately 400 PPM. Causes edema, dyspnoea,
bronchospasm, chest pain, pink frothy sputum. Inhalation of 500 PPM Ammonia considered immediately
dangerous to life and health (OSHA).
As with other corrosive alkalis: Severe burning of gullet, stomach, mouth, and throat. Possible death
from shock or asphyxia. Human lethal dose not established: Any amount can be dangerous.
No other potential chronic health effects known.
No No No

Section IV - First Aid Measures
Immediately flood with large amounts of water for at least 15 minutes. Seek prompt medical attention.
Quickly remove contaminated clothing Immediately wash area with large amounts of water for at least 15
minutes. Seek prompt medical attention. Wash clothing before re-use.
Ingestion: Do not induce vomiting. Encourage victim to drink large amounts of water, substituting as available, diluted
vinegar or citrus juices. Seek prompt medical attention.
Inhalation: Use respiratory protection as necessary and remove to fresh air at once. If breathing stops, give artificial
respiration. Seek prompt medical attention.

Flash Point: ____________________________ Autoignition Temperature: ____________________________
Lower: 16% Upper: 25%
(Based on Ammonia) (Based on Ammonia)
Lower Explosive Limit: ____________________________ Upper Explosive Limit: ____________________________
(Based on ammonia). Ammonia increases the fire hazard from other combustible materials, includ-
Unusual Fire and
ing oil. Flammable limits are broadened by increasing temperature. Ammonia vapor in the range of
16-25% in air can explode on contact with ignition sources.
Extinguishing Media: Fire extinguishing agents recommended: Water spray
Fire extinguishing agents to avoid: CO2 may react violently
Special Firefighting Wear full protective clothing. Stop flow of gas before extinguishing fire. Use water spray to keep
fire-exposed containers cool.

Section VI - Accidental Release Measures
Remain upwind of spill or leak. Evacuate immediate areas and wear appropriate protective equipment
depending on the concentration of ammonia in immediate area.
In unknown concentrations SCBA must be worn. Keep ignition sources away.
If spill could potentially enter any waterway, including intermittent dry creeks, contact the local authorities.
If in the U.S., contact the US COAST GUARD NATIONAL RESPONSE CENTER toll free number
800-424-8802. In case of accident or road spill notify: CHEMTREC IN USA at 800-424-9300; CANUTEC
in Canada at 613-996-6666 CHEMTREC in other countries at (International code)+1-703-527-3887.
See Section XIII for disposal information and Section XV for regulatory requirements. Large and
small spills may have a broad definition depending on the user's handling system. Therefore, the spill
category must be defined at the point of release by technically qualified personnel.
Section VII - Handling and Storage
Provide ventilation sufficient to maintain exposure below TWA/TLV/PEL (based on ammonia).
Handling: Avoid all contact of liquid with the body. Minimize gas contact. Good maintenance to prevent leaks. Keep
away from heat and open flames. Use good process control.
Storage: Preferably stored outside, otherwise in cool, dry well-ventilated non-combustible location, away from all
possible sources of ignition and oxidizers. Protect containers from heat, corrosion.
Storage and physical damage ?in locating storage areas, consideration should be given to health and fire
hazards, population density, and proximity of water supplies. Also, closed containers should be provided
with safety relief valves, as necessary.
Section VIII - Exposure Controls/ Personal Protection
Provide ventilation sufficient to maintain exposure below TWA/TLV/PEL (based on ammonia).
Wear hard hat, chemical safety goggles, full-face shield if eyes are not covered by respiratory
device. Do not wear contact lenses
Protective Clothing: Wear rubber apron, impervious protective clothing and rubber boots for routine product use.
Specialized handling ?alkali-resistant gloves. For leak or spill or other emergency, use full protective
Respiratory Use an approved NIOSH ammonia respirator. (Special: refers to a specific cartridge or canister for
Protection: NH3 gas.) Up to 100 PPM chemical cartridge respirator, special, supplied-air respirator, or self-con-
tained breathing apparatus. 100 to 300 PPM, chemical cartridge respirator, special with full-face
piece. Supplied air respirator (gas mask, special supplied-air respirator, or self-contained breathing
apparatus) required for exposure of 300 ppm or greater. Latter two types should have full-face
Other Protective Provide safety shower and eye wash facility at sites of handling and storage.
