|
POTENTIAL HAZARDS |
|
| - May react violently or explosively on contact with water. |
| - Some are transported in flammable liquids. |
| - May be ignited by friction, heat, sparks or flames. |
| - Some of these materials will burn with intense heat. |
| - Dusts or fumes may form explosive mixtures in air. |
| - Containers may explode when heated. |
| - May re-ignite after fire is extinguished. |
|
|
| - Oxides from metallic fires are a severe health hazard. |
| - Inhalation or contact with substance or decomposition products may cause severe injury 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. |
| - Stay upwind, uphill and/or upstream. |
| - Keep unauthorized personnel away. |
|
|
| - Wear positive pressure self-contained breathing apparatus (SCBA). |
| - Structural firefighters' protective clothing provides thermal protection but only limited chemical protection. |
|
|
| 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 50 meters (160 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. |
| - 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 |
|
| - DO NOT USE WATER, FOAM OR CO2. |
| - Dousing metallic fires with water will generate hydrogen gas, an extremely dangerous explosion hazard, particularly if fire is in a confined environment (i.e., building, cargo hold, etc.). |
| - Use DRY sand, graphite powder, dry sodium chloride-based extinguishers, or class D extinguishers. |
| - Confining and smothering metal fires is preferable rather than applying water. |
| - If it can be done safely, move undamaged containers away from the area around the fire. |
| Fire Involving Tanks or Car/Trailer Loads |
| - If impossible to extinguish, protect surroundings and allow fire to burn itself out. |
|
|
| - ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. |
| - Do not touch or walk through spilled material. |
| - Stop leak if you can do it without risk. |
| - Prevent entry into waterways, sewers, basements or confined areas. |
|
|
| - 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. |
| - In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. |
| - Keep victim calm and warm. |
