117 Gases - Toxic - Flammable (Extreme
Hazard)
 |
| POTENTIAL HAZARDS |
HEALTH |
*
TOXIC; Extremely Hazardous. * May be fatal if inhaled or absorbed through skin. * Initial
odor may be irritating or foul and may deaden your sense of smell. * Contact with gas or
liquefied gas may cause burns, severe injury and/or frostbite. * Fire will produce
irritating, corrosive and/or toxic gases. * Runoff from fire control may cause pollution. |
FIRE
OR EXPLOSION |
*
These materials are extremely flammable. * May form explosive mixtures with air. * May be
ignited by heat, sparks or flames. * Vapors from liquefied gas are initially heavier than
air and spread along ground. * Vapors may travel to source of ignition and flash back. *
Runoff may create fire or explosion hazard. * Containers may explode when heated. *
Ruptured cylinders may rocket. |
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. * 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
entering. |
PROTECTIVE
CLOTHING |
*
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. |
EVACUATION |
Spill:
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 "PUBLIC SAFETY". |
Fire:
If tank, rail car or tank truck is involved in a fire, ISOLATE for 1600 meters (1
mile) in all directions; also, consider initial evacuation for 1600 meters (1 mile) in all
directions. |
EMERGENCY
RESPONSE |
FIRE |
*
DO NOT EXTINGUISH A LEAKING GAS FIRE UNLESS LEAK CAN BE STOPPED. |
Small
Fires: Dry chemical, CO2, water spray or regular foam. |
Large
Fires: * Water spray, fog or regular foam. * 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 nozzles. * Cool containers with flooding quantities of water until well after fire
is out. * 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. |
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. * Fully encapsulating,
vapor protective clothing should be worn for spills and leaks with no fire. * Do not touch
or walk through spilled material. * Stop leak if you can do it without risk. * 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. * Consider
igniting spill or leak to eliminate toxic gas concerns. |
FIRST
AID |
*
Move victim to fresh air. * Call 911 or emergency medical service. * 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 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 contact with liquefied gas, thaw
frosted parts with lukewarm water * 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. |
