FLAMMABLE LIQUIDS - CORROSIVE |
|
POTENTIAL HAZARDS
|
|
- Flammable/combustible material.
|
- May be ignited by heat, sparks or flames. |
- Vapors may form explosive mixtures with air. |
- Vapors may travel to source of ignition and flash back. |
- Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). |
- Vapor explosion hazard indoors, outdoors or in sewers. |
- Those substances designated with a "P" may polymerize explosively when heated or involved in a fire.
|
- Runoff to sewer may create fire or explosion hazard. |
- Containers may explode when heated. |
- Many liquids are lighter than water. |
|
|
- May cause toxic effects if inhaled or ingested/swallowed. |
- Contact with substance may cause severe burns to skin and eyes. |
- Fire will produce irritating, corrosive and/or toxic gases. |
- Vapors may cause dizziness or suffocation. |
- 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 for at least 50 meters (150 feet) in all directions. |
- 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. |
|
|
Large 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
|
|
- Some of these materials may react violently with water.
|
Small Fire
|
- Dry chemical, CO2, water spray or alcohol-resistant foam. |
Large Fire
|
- Water spray, fog or alcohol-resistant foam. |
- Move containers from fire area if you can do it without risk. |
- Dike fire-control water for later disposal; do not scatter the material. |
- Do not get water inside containers. |
Fire involving Tanks or Car/Trailer Loads
|
- Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. |
- 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. |
- For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. |
|
|
- Fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. |
- ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). |
- All equipment used when handling the product must be grounded. |
- 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. |
- A vapor suppressing foam may be used to reduce vapors. |
- Absorb with earth, sand or other non-combustible material and transfer to containers (except for Hydrazine). |
- Use clean non-sparking tools to collect absorbed material. |
Large Spill
|
- Dike far ahead of liquid spill for later disposal. |
- Water spray may reduce vapor; but may not prevent ignition in closed spaces. |
|
|
- Move victim to fresh air. |
- Call 911 or emergency medical service. |
- Give artificial respiration if victim is not breathing. |
- Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. |
- 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. |
- In case of burns, immediately cool affected skin for as long as possible with cold water. Do not remove clothing if adhering to skin. |
- Keep victim warm and quiet. |
- Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. |
- Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. |
