HEALTH
* TOXIC; may be fatal if inhaled or absorbed through skin. * 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
* Flammable; may be ignited by heat, sparks or flames. * May form explosive mixtures with air. * Those substances designated with a "P" may polymerize explosively when heated or involved in a fire. * Vapors from liquefied gas are initially heavier than air and spread along ground. * Vapors may travel to source of ignition and flash back. * Some of these materials may react violently with water. * Containers may explode when heated. * Ruptured cylinders may rocket. * Runoff may create fire or explosion hazard.
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.
FIRE
* DO NOT EXTINGUISH A LEAKING GAS FIRE UNLESS LEAK CAN BE STOPPED.
Small Fires: Dry chemical, CO2, water spray or alcohol-resistant foam.
Large Fires: * Water spray, fog or alcohol-resistant foam. * FOR CHLOROSILANES, DO NOT USE WATER; use AFFF alcohol-resistant medium expansion 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. * Do not direct water at spill or source of leak. * Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material. * FOR CHLOROSILANES, use AFFF alcohol-resistant medium expansion foam to reduce vapors. * 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.
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.
