                                POTENTIAL HAZARDS

 HEALTH

 � Vapors may cause dizziness or asphyxiation without warning.

 � Vapors from liquefied gas are initially heavier than air and spread along ground.

 � Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite.

 FIRE OR EXPLOSION

 � Non-flammable gases.

 � 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.

 � As an immediate precautionary measure, isolate spill or leak area for at least 100 meters

   (330 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).

 � Structural firefighters� protective clothing will only provide limited protection.

 � Always wear thermal protective clothing when handling refrigerated/cryogenic liquids or

   solids.

 EVACUATION

 Large Spill

 � Consider initial downwind evacuation for at least 100 meters (330 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

   � Use extinguishing agent suitable for type of surrounding fire.

   � 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

   � 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.

   � Allow substance to evaporate.

   � Ventilate the area.

   CAUTION: When in contact with refrigerated/cryogenic liquids, many materials

     become brittle and are likely to break without warning.

  FIRST AID

   �   Move victim to fresh air. � Call 911 or emergency medical service.

   �   Give artificial respiration if victim is not breathing.

   �   Administer oxygen if breathing is difficult.

   �   Clothing frozen to the skin should be thawed before being removed.

   �   In case of contact with liquefied gas, thaw frosted parts with lukewarm water.

   �   Keep victim warm and quiet.

   �   Ensure that medical personnel are aware of the material(s) involved and take

       precautions to protect themselves.
