SPECIAL PROVISIONS
- IB2 Authorized Intermediate Bulk Containers: Metal (31A, 31B and 31N); Rigid plastics (31H1 and 31H2); Composite (31HZ1). Additional Requirement: Only liquids with a vapor pressure less than or equal to 110 kPa at 50 deg.C (1.1 bar at 122 deg.F), or 130kPa at 55 deg.C (1.3 bar at 131 deg.F) are authorized.

- T4 Portable tanks: Consult the regulations for specific requirements Sec. 172.102 Special Provision Table T Code T1-T22.
- TP1 Tank Provision: The maximum degree of filling must not exceed the degree of filling determined by the following equation: Degree of filling = 97 /(1 + alpha(Tr - Tf)) where Tr is the maximum mean bulk temperature during transport, Tf is the temperature in degrees celsius of the liquid during filling and alpha is the is the mean coefficient of cubical expansion of the liquid between the mean temperature of the liquid during filling Tf and the maximum mean bulk temperature during transportation Tr both in degrees celsius.

POTENTIAL HAZARDS
FIRE OR EXPLOSION
- HIGHLY FLAMMABLE: Will be easily 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.
HEALTH
- May cause toxic effects if inhaled or absorbed through skin.
- Inhalation or contact with material may irritate or burn 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
unavailable use phone numbers listed in the database help
or in Canada - CANUTEC 613-996-6666; USA - CHEMTREC 1-800-424-9300.
- Isolate spill or leak area immediately for at least 50 to 100 meters
(160 to 330 feet) in all directions.
- Keep unauthorized personnel away.
- Stay upwind.
- Keep out of low areas.
- Ventilate closed spaces before entering.
PROTECTIVE CLOTHING
- Wear positive pressure self-contained breathing apparatus (SCBA).
- Structural firefighters' protective clothing will only provide limited
protection.
EVACUATION
Large Spill
- Consider initial downwind evacuation for at least 300 meters
(1000 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.
EMERGENCY RESPONSE
FIRE
- CAUTION: All these products have a very low flash point: Use of water spray
when fighting fire may be inefficient.
Small Fires
- Dry chemical, CO2, water spray or regular foam.
Large Fires
- Water spray, fog or regular foam.
- Do not use straight streams.
- Move containers from fire area if you can do it without risk.
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.
SPILL OR LEAK
- 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 or cover with dry earth, sand or other non-combustible material
and transfer to containers.
- Use clean non-sparking tools to collect absorbed material.
Large Spills
- Dike far ahead of liquid spill for later disposal.
- Water spray may reduce vapor; but may not prevent ignition in closed
spaces.
FIRST AID
- Move victim to fresh air.
- Call 911 or emergency medical service.
- Apply 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.
- Wash skin with soap and water.
- 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.
