SUBSTANCES - WATER-REACTIVE (Emitting Flammable Gases)
POTENTIAL HAZARDS
FIRE OR EXPLOSION
· Produce flammable gases on contact with water.
· May ignite on contact with water or moist air.
· Some react vigorously or explosively on contact with water.
· May be ignited by heat, sparks or flames.
· May re-ignite after fire is extinguished.
· Some are transported in highly flammable liquids.
· Runoff may create fire or explosion hazard.
HEALTH
· Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death.
· May produce corrosive solutions on contact with water.
· Fire will produce irritating, corrosive and/or toxic gases.
· Runoff from fire control may cause pollution.
PUBLIC SAFETY
· CALL EMERGENCY RESPONSE Telephone Number on Shipping Paper first. If Shipping Paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.
· As an 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.
· Keep unauthorized personnel away.
· Stay upwind, uphill and/or upstream.
· Ventilate the area before entry.
PROTECTIVE CLOTHING
· Wear positive pressure self-contained breathing apparatus (SCBA).
· Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection.
· Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible.
EVACUATION
Spill
· See the Initial Isolation and Protective Action Distances for highlighted materials. For non-highlighted materials, increase, in the downwind direction, as necessary, the isolation distance shown under "PUBLIC SAFETY".
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.
In Canada, an Emergency Response Assistance Plan (ERAP) may be required for this product. Please consult the shipping document and/or the Canada and United States National Response Centers reference document.

Also, see GUIDE 170.
Fire involving Tanks or Car/Trailer Loads
· Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
· Do not get water inside containers.
· Cool containers with flooding quantities of water until well after fire is out.
· Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
· ALWAYS stay away from tanks engulfed in fire.
SPILL OR LEAK
· ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area).
· Do not touch or walk through spilled material.
· Stop leak if you can do it without risk.
· Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material.
· DO NOT GET WATER on spilled substance or inside containers.
Small Spill
· Cover with DRY earth, DRY sand or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain.
· Dike for later disposal; do not apply water unless directed to do so.
Powder Spill
· Cover powder spill with plastic sheet or tarp to minimize spreading and keep powder dry.
· DO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST.
