138 Substances - Water-Reactive (Emitting Flammable Gases)              hpbutton.gif (1641 bytes)

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. * Isolate spill or leak area immediately for at least 50 to 100 meters (160 to 330 feet) in all directions. * Keep unauthorized personnel away. * Stay upwind. * Keep out of low areas. * Ventilate the area before entry.

PROTECTIVE CLOTHING

* Wear positive pressure self-contained breathing apparatus (SCBA). * Structural firefighters' protective clothing will only provide limited protection.

EVACUATION

Large Spill:  Consider initial downwind evacuation for at least 250 meters (800 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.

EMERGENCY RESPONSE

FIRE

* DO NOT USE WATER OR FOAM.

Small Fires:  Dry chemical, soda ash, lime or sand.

Large Fires:  * DRY sand, dry chemical, soda ash or lime or withdraw from area and let fire burn. * Move containers from fire area if you can do it without risk.

Magnesium Fires:  DRY sand, sodium chloride powder, graphite powder or Met-L-X powder.

Lithium Fires:  DRY sand, sodium chloride powder, graphite powder, copper powder or Lith-X powder.

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 Spills:  * 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 Spills:  * 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.

FIRST AID

* Move victim to fresh air. * Call 911 or emergency medical service. * Apply artificial respiration if victim is not breathing. * Administer oxygen if breathing is difficult. * Remove and isolate contaminated clothing and shoes. * In case of contact with substance, wipe from skin immediately; flush skin or eyes with running water for at least 20 minutes. * Keep victim warm and quiet. * Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves.
