OXIDIZERS (Unstable) |
|
POTENTIAL HAZARDS
|
|
| - May explode from friction, heat or contamination. |
| - These substances will accelerate burning when involved in a fire. |
| - May ignite combustibles (wood, paper, oil, clothing, etc.). |
| - Some will react explosively with hydrocarbons (fuels). |
| - Containers may explode when heated. |
| - Runoff may create fire or explosion hazard. |
|
|
| - TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. |
| - Fire may produce irritating and/or toxic gases. |
| - Toxic fumes or dust may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). |
| - Runoff from fire control or dilution water 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. |
| - Keep out of low areas. |
| - Ventilate closed spaces before entering. |
|
|
| - 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. |
|
|
|
Spill
|
| - See Table 1 - 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. |
|
|
EMERGENCY RESPONSE
|
|
|
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.
|
| - Move containers from fire area if you can do it without risk. |
| - Do not get water inside containers: a violent reaction may occur. |
|
Fire involving Tanks or Car/Trailer Loads
|
| - Cool containers with flooding quantities of water until well after fire is out. |
| - Dike fire-control water for later disposal. |
| - ALWAYS stay away from tanks engulfed in fire. |
| - For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. |
|
|
| - Keep combustibles (wood, paper, oil, etc.) away from spilled material. |
| - Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. |
| - Use water spray to reduce vapors or divert vapor cloud drift. |
| - Prevent entry into waterways, sewers, basements or confined areas. |
|
Small Spill
|
| - Flush area with flooding quantities of water. |
|
Large Spill
|
|
- DO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST.
|
|
|
| - Move victim to fresh air. |
| - Call 911 or emergency medical service. |
| - 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 warm and quiet. |
| - Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. |
