POTENTIAL HAZARDS HEALTH · TOXIC; may be fatal if inhaled, ingested or absorbed through skin. · Vapors are extremely irritating and corrosive. · 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 or dilution water may cause environmental contamination. FIRE OR EXPLOSION · Some may burn but none ignite readily. · Vapors from liquefied gas are initially heavier than air and spread along ground. · Some of these materials may react violently with 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. . For UN1005: Anhydrous ammonia, at high concentrations in confined spaces, presents a flammability risk if a source of ignition is introduced. · 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 · For highlighted materials: see Table 1 - . · For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind direction, as necessary. 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.  | 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. |
EMERGENCY RESPONSE FIRE Small Fire · Dry chemical or CO2. Large Fire · Water spray, fog or regular foam. · If it can be done safely, move undamaged containers away from the area around the fire. · Do not get water inside containers. · 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. SPILL OR LEAK · Do not touch or walk through spilled material. · Stop leak if you can do it without risk. · If possible, turn leaking containers so that gas escapes rather than liquid. · Prevent entry into waterways, sewers, basements or confined areas. · 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. · Isolate area until gas has dispersed. 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. · Remove and isolate contaminated clothing and shoes. · In case of contact with liquefied gas, thaw frosted parts with lukewarm water. · In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. · In case of skin contact with hydrogen fluoride, anhydrous (UN1052), if calcium gluconate gel is available, rinse 5 minutes, then apply gel. Otherwise, continue rinsing until medical treatment is available. · Keep victim calm and warm. · Keep victim under observation. · Effects of contact or inhalation may be delayed. |
