SPECIAL PROCEDURES:
Ammonia requires a high energy source to ignite and has a limited
range of flammability. Ammonia is NOT considered or classified as a
flammable gas. Pockets of gas may form near the ceilings of
enclosed areas due to its low density.
Cool containers with water spray from maximum distance. Do not
aim at source: gas may reignite easily. Evacuate area. Shut off gas if
it can be done without risk. Containers may rupture when subject to
localized heating. Let escaping gas burn, while keeping the container
cool from distance, until the container is empty.

Evacuate areas where a leak or a spill is present. Fight surrounding
fires as the case may be. Use water spray to absorb any escaping
gas. Approach areas only with S.C.B.A. and full chemical resistant
clothes. Ammonia is very irritating and corrosive to the unprotected
skin. Keep upwind. Evacuate downwind as necessary.

All acute exposures to NH3 will result in corrosion damage to the
organ(s). Skin, Eye, Nose and Lungs may be damaged severely
depending on the duration of the exposure. Eye irritation starts @
20ppm, severe irritation with burns @ 50ppm. Blindness may occur
with exposure to 5,000 to 20,000ppm (30 to 5 minutes respectively).
Burning of the Nose mucous may start @ 130ppm. Exposures to
80ppm/2hrs (or 110ppm/30min) may cause lung irritation and
coughing. 1000ppm over 10 minutes may cause burns to the
respiratory tract leading to pulmonary edema. Over 4000ppm for 515 minutes may result in loss of coordination, unconsciousness,
convulsions, coma and death. Exposures to 3% may be fatal in 5
minutes. Ingestion of liquid may cause internal corrosion damage.
Frostbite may occur for short term skin contact with the liquid.

FIRST AID
EYE:
INGESTION:
INHALATION:
SKIN:
Gas may harm the unprotected eye. Wash with large amounts of water IMMEDIATELY
for at lease 15 minutes. Obtain medical attention as soon as practical and if damages are
suspected or present.
Give water (milk) to dilute. Allow for vomiting. Prevent suffocation from vomiting. Obtain
medical attention IMMEDIATELY.
Move victim to fresh air if possible. Administer C.P.R. if breathing has stopped. If
breathing is difficult give oxygen. OBTAIN MEDICAL ATTENTION AT ONCE (advice the
physician that symptoms may be delayed).
Remove contaminated clothing, wash affected areas for 15 minutes with water, use
sterile bandages on burns. OBTAIN MEDICAL ATTENTION IMMEDIATELY.
PREVENTIVE MEASURES
PERSONAL PROTECTION
EYE:
HAND:
FEET:
CLOTHING:
RESPIRATOR:
Full face mask to protect from liquid splashing.
Neoprene gloves
Safety footwear where applicable.
Long sleeves, trousers recommended. Clothes should be anti-static (i.e. 100% Cotton).
Chemical cartridges may be effective up to 300ppm. Supplied air may be necessary for
higher concentrations. THE CHOICE OF THE REQUIRED RESPIRATOR MUST BE
MADE BASED ON THE ACTUAL EXPOSURE LEVELS. ENGINEERING TO KEEP THE
EXPOSURE LEVELS THE LOWEST POSSIBLE MUST BE CONSIDERED THE FIRST
APPROACH.
ENGINEERING CONTROLS: Provide good ventilation. Keep away from all sources of ignition. Use only electrical
equipment designed for a CORROSIVE /Flammable (alkali) atmosphere. Specific design
considerations may be necessary for piping and vessels. Use of gas monitors may be
appropriate where gas accumulation may occur.
SPILL AND LEAK PROCEDURE:Remove all sources of ignition. Shutoff the source if without risk. Use SCBA to enter
confined spaces, if necessary after monitoring for the concentration of NH3 and oxygen
content. Try to stop any leak at source if without risk. Gas with dissipate depending on
the site/area ventilation. Escaping gas will rise rapidly. Verify oxygen concentration prior
to re-entry. NH3 may cause corrosion damages upon leaking especially if water is
present.
WASTE DISPOSAL:
Do not discard empty cylinders. Return the cylinder where applicable. Waste cylinders
may have to be disposed in accordance to Federal, Provincial and Municipal
requirements.
UYI 117-4
HANDLING PROCEDURES & EQUIPMENT:Keep away from ALL SOURCES OF IGNITION. Ensure food ventilation.
Use appropriate carts for moving containers. Secure container when in use. Close the
container valve when not in use or empty. Secure (restrain) during transportation or use.
Use backflow preventive devices (checkvalves) on piping and tubing (including hoses).
Use only with equipment designed for Methane use. Keep containers upright when in
use.
STORAGE REQUIREMENTS:Store in well ventilated areas. Keep away from sources of ignition. Store at
temperatures below 52 oC (125oF).
SPECIAL SHIPPING INFORMATION:Transport upright in well-ventilated vehicle. Do not transport in trunk of enclosed
vehicle. Commercial (cylinders) quantities may NOT be transported in passenger
compartments.
