POTENTIAL HAZARDS |
|
- Flammable/combustible material. |
- May ignite on contact with moist air or moisture. |
- May burn rapidly with flare-burning effect. |
- Some react vigorously or explosively on contact with water. |
- Some may decompose explosively when heated or involved in a fire. |
- May re-ignite after fire is extinguished. |
- Runoff may create fire or explosion hazard. |
- Containers may explode when heated. |
|
|
- Fire will produce irritating, corrosive and/or toxic gases. |
- Inhalation of decomposition products may cause severe injury or death. |
- Contact with substance may cause severe burns to skin and eyes. |
- Runoff from fire control or dilution water may cause environmental contamination. |
CAUTION: Pentaborane (UN1380) is highly toxic and may be fatal if inhaled, ingested or absorbed through skin. |
|
|
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). |
- Wear chemical protective clothing that is specifically recommended by the manufacturer when there is NO RISK OF FIRE. |
- 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. |
Spill |
- For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances. |
- For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind direction, as necessary. |
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, CO2 OR FOAM ON MATERIAL ITSELF. |
- Some of these materials may react violently with water. |
CAUTION: For Xanthates, UN3342 and for Dithionite (Hydrosulfite/Hydrosulphite) UN1384, UN1923 and UN1929, USE FLOODING AMOUNTS OF WATER for SMALL AND LARGE fires to stop the reaction. Smothering will not work for these materials, they do not need air to b |
Small Fire |
- Dry chemical, soda ash, lime or DRY sand, EXCEPT for UN1384, UN1923, UN1929 and UN3342. |
Large Fire |
- DRY sand, dry chemical, soda ash or lime EXCEPT for UN1384, UN1923, UN1929 and UN3342, or withdraw from area and let fire burn. |
CAUTION: UN3342 when flooded with water will continue to evolve flammable Carbon disulfide/Carbon disulphide vapors. |
- If it can be done safely, move undamaged containers away from the area around the fire. |
Fire Involving Tanks or Car/Trailer Loads |
- Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. |
- Do not get water inside containers or in contact with substance. |
- 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. |
|
|
- 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. |
Small Spill |
CAUTION: For spills of Xanthates, UN3342 and for Dithionite (Hydrosulfite/Hydrosulphite), UN1384, UN1923 and UN1929, dissolve in 5 parts water and collect for proper disposal. |
CAUTION: UN3342 when flooded with water will continue to evolve flammable Carbon disulfide/Carbon disulphide vapors. |
- Cover with DRY earth, DRY sand or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. |
- Use clean, non-sparking tools to collect material and place it into loosely covered plastic containers for later disposal. |
- 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. |
