POTENTIAL HAZARDS
FIRE OR EXPLOSION
· These substances will accelerate burning when involved in a fire.
· Some may decompose explosively when heated or involved in a fire.
· May explode from heat or contamination.
· Some will react explosively with hydrocarbons (fuels).
· May ignite combustibles (wood, paper, oil, clothing, etc.).
· Containers may explode when heated.
· Runoff may create fire or explosion hazard.
HEALTH
· Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death.
· Fire may produce irritating, corrosive and/or toxic gases.
· Runoff from fire control or dilution water may cause environmental contamination.
PUBLIC SAFETY
· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.
· Keep unauthorized personnel away.
· Stay upwind, uphill and/or upstream.
· Ventilate closed spaces before entering, but only if properly trained and equipped.
PROTECTIVE CLOTHING
· Wear positive pressure self-contained breathing apparatus (SCBA).
· Wear chemical protective clothing that is specifically recommended by the manufacturer when there is NO RISK OF FIRE.
· Structural firefighters' protective clothing provides thermal protection but only limited chemical protection.
EVACUATION
Immediate precautionary measure
· Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.
Large Spill
· Consider initial downwind evacuation for at least 100 meters (330 feet).
Fire
· If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.
· If ammonium nitrate is in a tank, rail car or tank truck and involved in a fire, ISOLATE for 1600 meters (1 mile) in all directions; also, initiate evacuation including emergency responders for 1600 meters (1 mile) in all directions.
In Canada, an Emergency Response Assistance Plan (ERAP) may be required for this product. Please consult the shipping paper and/or the ERAP Program Section (page 390).
EMERGENCY RESPONSE
FIRE
Small Fire
· Use water. Do not use dry chemicals or foams. CO2 or Halon® may provide limited control.
Large Fire
· Flood fire area with water from a distance.
· Do not move cargo or vehicle if cargo has been exposed to heat.
· If it can be done safely, move undamaged containers away from the area around the fire.
Fire Involving Tanks or Car/Trailer Loads
· Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles.
· Cool containers with flooding quantities of water until well after fire is out.
· ALWAYS stay away from tanks engulfed in fire.
· For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn.
SPILL OR LEAK
· Keep combustibles (wood, paper, oil, etc.) away from spilled material.
· Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.
· Stop leak if you can do it without risk.
· Do not get water inside containers.
Small Dry Spill
· With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area.
Small Liquid Spill
· Use a non-combustible material like vermiculite or sand to soak up the product and place into a container for later disposal.
Large Spill
· Dike far ahead of liquid spill for later disposal.
FIRST AID
· Call 911 or emergency medical service.
· Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.
· Move victim to fresh air if it can be done safely.
· Give artificial respiration if victim is not breathing.
· Administer oxygen if breathing is difficult.
· Remove and isolate contaminated clothing and shoes.
· Contaminated clothing may be a fire risk when dry.
· In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
· Keep victim calm and warm.
