|CAS Number||UN/NA Number||DOT Hazard Label||USCG CHRIS Code|
|NIOSH Pocket Guide||International Chem Safety Card|
|Health||4||Can be lethal.|
|Flammability||4||Burns readily. Rapidly or completely vaporizes at atmospheric pressure and normal ambient temperature.|
|Instability||4||Readily capable of detonation or explosive decomposition or explosive reaction at normal temperatures and pressures.|
- Strong Oxidizing Agent
Behavior in Fire: Vapors are heavier than air and may travel a considerable distance to a source of ignition and flash back; can decompose violently above 194°F; containers may explode in a fire. (USCG, 1999)
Use caution: Liquids with this reactive group classification have been known to react with the absorbents listed below. More info about absorbents, including situations to watch out for...
- Cellulose-Based Absorbents
- Expanded Polymeric Absorbents
As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions.
SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above.
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. (ERG, 2016)
CAUTION: All these products have a very low flash point: Use of water spray when fighting fire may be inefficient.
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. Use water spray or fog; do not use straight streams.
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. (ERG, 2016)
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.
SMALL SPILL: Absorb with earth, sand or other non-combustible material and transfer to containers for later disposal. 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. (ERG, 2016)
EYES: flush with water for at least 15 min.; get medical attention if irritation persists.
SKIN: flush with water, wash with soap and water.
INGESTION: do NOT induce vomiting; call physician. (USCG, 1999)
