Toxic and/or Corrosive
- TOXIC; may be fatal if inhaled
or absorbed through skin.
- Fire will produce irritating,
corrosive and/or toxic gases.
- Contact with gas or liquefied
gas may cause burns, severe injury and/or
- Runoff from fire control may
FIRE OR EXPLOSION
- Substance does not burn but will
- Vapors from liquefied gas are initially
heavier than air and spread along
- These are strong oxidizers and will
react vigorously or explosively with
many materials including fuels.
- May ignite combustibles (wood, paper,
oil, clothing, etc.).
- Some will react violently with air,
moist air and/or water.
- Containers may explode when heated.
- Ruptured cylinders may rocket.
- 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.
- Isolate spill or leak area immediately
for at least 100 to 200 meters (330
to 660 feet) in all directions.
- Keep unauthorized personnel away.
- Stay upwind.
- Many gases are heavier than air
and will spread along ground and collect
in low or confined areas (sewers, basements, tanks).
- Keep out of low areas.
- Ventilate closed spaces before
- Wear positive pressure self-contained
breathing apparatus (SCBA).
- Wear chemical protective clothing
which 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.
- See the Table of Initial Isolation
and Protective Action Distances for highlighted
substances. For non-highlighted substances, increase, in the
downwind direction, as necessary, the isolation distance shown under
- 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.
- Small Fires: Water only; no
dry chemical, CO2 or Halon.
- Contain fire and let burn. If
fire must be fought, water spray or fog is
- Do not get water inside containers.
- Move containers from fire area
if you can do it without risk.
- Damaged cylinders should be handled
only by specialists.
Fire involving Tanks
- Fight fire from maximum distance
or use unmanned hose holders or monitor
- Cool containers with flooding
quantities of water until well after fire
- Do not direct water at source
of leak or safety devices; icing may occur.
- 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
- Fully encapsulating, vapor protective
clothing should be worn for spills
and leaks with no fire.
- Do not touch or walk through
- Keep combustibles (wood, paper,
oil, etc.) away from spilled material.
- Stop leak if you can do it without
- Use water spray to reduce vapors
or divert vapor cloud drift. Avoid allowing
water runoff to contact spilled material.
- Do not direct water at spill
or source of leak.
- If possible, turn leaking containers
so that gas escapes rather than liquid.
- Prevent entry into waterways,
sewers, basements or confined areas.
- Isolate area until gas has dispersed.
- Ventilate the area.
- Move victim to fresh air.
- Call 911 or emergency medical
- Apply artificial respiration
if victim is not breathing.
- Do not use mouth-to-mouth method
if victim ingested or inhaled the substance;
induce 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
- Clothing frozen to the skin should
be thawed before being removed.
- 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 warm and quiet.
- Keep victim under observation.
- Effects of contact or inhalation
may be delayed.
- Ensure that medical personnel
are aware of the material(s) involved, and
take precautions to protect themselves.
