POTENTIAL HAZARDS HEALTH · 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 frostbite. · Runoff from fire control or dilution water may cause environmental contamination. FIRE OR EXPLOSION · Substance does not burn but will support combustion. · Vapors from liquefied gas are initially heavier than air and spread along ground. · 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. · Cylinders exposed to fire may vent and release toxic and/or corrosive gas through pressure relief devices. · Containers may explode when heated. · Ruptured cylinders may rocket. · CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover. · Keep unauthorized personnel away. · Stay upwind, uphill and/or upstream. · Many gases are heavier than air and will spread along the ground and collect in low or confined areas (sewers, basements, tanks, etc.). · Ventilate closed spaces before entering, but only if properly trained and equipped. PROTECTIVE CLOTHING · Wear positive pressure self-contained breathing apparatus (SCBA). · Wear chemical protective clothing that is specifically recommended by the manufacturer when there is NO RISK OF FIRE. · Structural firefighters' protective clothing provides thermal protection but only limited chemical protection. Immediate precautionary measure · Isolate spill or leak area for at least 100 meters (330 feet) in all directions. Spill · See Table 1 - Initial Isolation and Protective Action Distances. 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.  | In Canada, an Emergency Response Assistance Plan (ERAP) may be required for this product. Please consult the shipping paper and/or the ERAP Program Section (page 390). |
EMERGENCY RESPONSE FIRE Small Fire CAUTION: These materials do not burn but will support combustion. Some will react violently with water. · Contain fire and let burn. If fire must be fought, water spray or fog is recommended. · Water only; no dry chemical, CO2 or Halon®. · Do not get water inside containers. · If it can be done safely, move undamaged containers away from the area around the fire. · Damaged cylinders should be handled only by specialists. Fire Involving Tanks · Fight fire from maximum distance or use unmanned master stream devices 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. · For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. SPILL OR LEAK · Do not touch or walk through spilled material. · Keep combustibles (wood, paper, oil, etc.) away from 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. · Ventilate the area. FIRST AID · Call 911 or emergency medical service. · Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. · Move victim to fresh air if it can be done safely. · Give artificial respiration if victim is not breathing. · Do not perform mouth-to-mouth resuscitation if victim ingested or inhaled the substance; wash face and mouth before giving artificial respiration. Use a pocket mask equipped with a one-way valve or other proper respiratory medical device. · Administer oxygen if breathing is difficult. · 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 calm and warm. · Keep victim under observation. · Effects of contact or inhalation may be delayed. |
