Emergency Response Guidebook (ERG)

This is an online version of the 2008 Emergency Response Guidebook (ERG) which is produced by the USDOT for first responders during the initial phase of a Dangerous goods/Hazardous Materials incident. Have you ever wondered what those four digit numbers on the placards on the side of trucks and rail cars mean? Our online ERG will give you your answer.

OXIDIZERS (Unstable)

POTENTIAL HAZARDS

FIRE OR EXPLOSION

  • May explode from friction, heat or contamination.
  • These substances will accelerate burning when involved in a fire.
  • May ignite combustibles (wood, paper, oil, clothing, etc.).
  • Some will react explosively with hydrocarbons (fuels).
  • Containers may explode when heated.
  • Runoff may create fire or explosion hazard.

HEALTH

  • TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death.
  • Fire may produce irritating and/or toxic gases.
  • Toxic fumes or dust may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.).
  • Runoff from fire control or dilution water may cause pollution.

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 in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.
  • Keep unauthorized personnel away.
  • Stay upwind.
  • Keep out of low areas.
  • Ventilate closed spaces before entering.

PROTECTIVE CLOTHING

  • Wear positive pressure self-contained breathing apparatus (SCBA).
  • Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection.
  • Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible.

EVACUATION

Spill
  • See Table 1 - Initial Isolation and Protective Action Distances for highlighted materials. For non-highlighted materials, increase, in the downwind direction, as necessary, the isolation distance shown under PUBLIC SAFETY.
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

Small Fire
  • Use water. Do not use dry chemicals or foams. CO2 or Halon® may provide limited control.
Large Fire
  • Flood fire area with water from a distance.
  • Do not move cargo or vehicle if cargo has been exposed to heat.
  • Move containers from fire area if you can do it without risk.
  • Do not get water inside containers: a violent reaction may occur.
Fire involving Tanks or Car/Trailer Loads
  • Cool containers with flooding quantities of water until well after fire is out.
  • Dike fire-control water for later disposal.
  • ALWAYS stay away from tanks engulfed in fire.
  • For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn.

SPILL OR LEAK

  • Keep combustibles (wood, paper, oil, etc.) away from spilled material.
  • Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.
  • Use water spray to reduce vapors or divert vapor cloud drift.
  • Prevent entry into waterways, sewers, basements or confined areas.
Small Spill
  • Flush area with flooding quantities of water.
Large Spill
  • DO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST.

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.
  • Remove and isolate contaminated clothing and shoes.
  • Contaminated clothing may be a fire risk when dry.
  • In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
  • Keep victim warm and quiet.
  • Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.
