D.O.T. Emergency Response Guide

    WHEN APPROACHING A HAZARDOUS MATERIALS INCIDENT:

    APPROACH CAUTIOUSLY. Resist the urge to rush in; you cannot help others until you know what you are facing.

    IDENTIFY THE HAZARDS. Placards, container labels, shipping papers and/or knowledgeable persons on the scene are valuable information sources. Evaluate all of them, and then consult the recommended guide page before you place yourself or others at risk. Do not be alarmed if new information from a CHEMTREC expert changes some of the emphasis or details of the guide page warnings. You must remember that the guide page provides only the most important information for your initial response with a family or class of hazardous materials. It is intended that as more accurate, i.e. material specific information becomes available, your response will become more appropriate for the situation.

    SECURE THE SCENE. Without entering the immediate hazard area, do what you can to isolate the area and assure the safety of people and the environment. Move and keep people away from the scene and the perimeter. Allow room enough to move and remove your own equipment.

    OBTAIN HELP. Advise your headquarters to notify responsible agencies and call for assistance from trained experts through CHEMTREC and the National Response Center which can be reached through CHEMTREC or dialed directly.

    DECIDE ON SITE ENTRY. Any efforts you make to rescue persons, protect property or the environment must be weighed against the possibility that you could become part of the problem. Enter the area with the appropriate protective gear. Above all - Do not walk into or touch spilled material. Avoid inhalation of fumes, smoke and vapors, even if no hazardous materials are known to be involved. Do not assume that gases or vapors are harmless because of lack of a smell.

ACETYLENE, DISSOLVED -UN 1001




POTENTIAL HAZARDS

    FIRE OR EXPLOSION
    Extremely flammable.
    May be ignited by heat, sparks or flames.
    Vapors may travel to a source of ignition and flashback.
    Container may explode violently in heat of fire.
    Vapor explosion hazard indoors, outdoors or in sewers.

    HEALTH HAZARDS
    If inhaled, may be harmful; contact may cause burns to skin and eyes.
    Vapors may cause dizziness or suffocation.
    Contact with liquid may cause frostbite..
    Fire may produce irritating or poisonous gases.

EMERGENCY ACTION

    Keep unnecessary people away, isolate hazard area and deny entry.
    Stay upwind, out of low areas, and ventilate closed spaces before entering.
    Self-contained breathing apparatus (SCBA) and structural firefighter's protective clothing will provide limited protection.
    Isolate for 1/2 mile in all directions if tank car or truck is involved in fire.
    CALL CHEMTREC AT 1-800-424-9300 AS SOON AS POSSIBLE., especially if there is no local hazardous materials team available.

    FIRE
    Let tank car, tank truck or storage tank burn unless leak can be stopped; with smaller tanks or cylinders, extinguish/isolate from other flammables.
    Small Fires: Dry chemical, CO2 or Halon.
    Large Fires: Water spray, fog or standard foam is recommended.
    Move container from fire area if you can do it without risk.
    Stay away from ends of tanks.
    For massive fire in cargo area, use unmanned hose holder or monitor nozzles; if this is impossible, withdraw from area and let fire burn.
    Withdraw immediately in case of rising sound from venting safety device or any discoloration of tank due to fire.

    SPILL OR LEAK
    Shut off ignition sources, no flares, smoking or flames in hazard area.
    Stop leak if you can do it without risk.
    Water spray may reduce vapor, but it may not prevent ignition in closed spaces.

    FIRST AID
    Move victim to fresh air and call emergency medical care; if not breathing, give artificial respiration., if breathing is difficult, give oxygen.
    In case of frostbite, thaw frosted parts with water.
    Keep victim quiet and maintain normal body temperature.
