POTENTIAL HAZARDS |
|
| - 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. |
|
|
| - 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. |
|
|
PUBLIC SAFETY |
| - 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. |
|
|
| - 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 - Initial Isolation and Protective Action Distances. |
| - 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 (page 390). |

|
EMERGENCY RESPONSE |
|
| 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. |
|
|
| - 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. |
|
|
| - 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. |
