138 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. * 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

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
