2004 ERG (Emergency Response Guidebook)

This is an online version of the 2004 ERG (Emergency Response Guidebook) 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 2004 ERG will give you your answer.

GUIDE 166
RADIOACTIVE MATERIALS - CORROSIVE (Uranium Hexafluoride / Water-Sensitive)

POTENTIAL HAZARDS

HEALTH

  • Radiation presents minimal risk to transport workers, emergency response personnel and the public during transportation accidents. Packaging durability increases as potential radiation and criticality hazards of the content increase.
  • Chemical hazard greatly exceeds radiation hazard.
  • Substance reacts with water and water vapor in air to form toxic and corrosive hydrogen fluoride gas and an extremely irritating and corrosive, white-colored, water-soluble residue.
  • If inhaled, may be fatal.
  • Direct contact causes burns to skin, eyes, and respiratory tract.
  • Low-level radioactive material; very low radiation hazard to people.
  • Runoff from control of cargo fire may cause low-level pollution.

FIRE OR EXPLOSION

  • Substance does not burn.
  • The material may react violently with fuels.
  • Containers in protective overpacks (horizontal cylindrical shape with short legs for tie-downs), are identified with "AF", "B(U)F" or "H(U)" on shipping papers or by markings on the overpacks. They are designed and
evaluated to withstand severe conditions including total engulfment in flames at temperatures of 800¦C (1475¦F).
  • Bare filled cylinders, identified with UN2978 as part of the marking (may also be marked H(U) or H(M)), may rupture in heat of engulfing fire; bare empty (except for residue) cylinders will not rupture in fires.
  • Radioactivity does not change flammability or other properties of materials.

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.
  • Priorities for rescue, life-saving, first aid, fire control and other hazards are higher than the priority for measuring radiation levels.
  • Radiation Authority must be notified of accident conditions. Radiation Authority is usually responsible for decisions about radiological consequences and closure of emergencies.
  • As an immediate precautionary measure, isolate spill or leak area for at least 25 meters (75 feet) in all directions.
  • Stay upwind.
  • Keep unauthorized personnel away.
  • Detain or isolate uninjured persons or equipment suspected to be contaminated; delay decontamination and cleanup until instructions are received from Radiation Authority.

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

Large Spill
  • See the Table of Initial Isolation and Protective Action Distances.
Fire
  • When a large quantity of this material is involved in a major fire, consider an initial evacuation distance of 300 meters (1000 feet) in all directions.

EMERGENCY RESPONSE

FIRE

  • DO NOT USE WATER OR FOAM ON MATERIAL ITSELF.
  • Move containers from fire area if you can do it without risk.
Small Fires
  • Dry chemical or CO2.
Large Fires
  • Water spray, fog or regular foam.
  • Cool containers with flooding quantities of water until well after fire is out.
  • If this is impossible, withdraw from area and let fire burn.
  • ALWAYS stay away from tanks engulfed in fire.

SPILL OR LEAK

  • Do not touch damaged packages or spilled material.
  • Without fire or smoke, leak will be evident by visible and irritating vapors and residue forming at the point of release.
  • Use fine water spray to reduce vapors; do not put water directly on point of material release from container.
  • Residue buildup may self-seal small leaks.
  • Dike far ahead of spill to collect runoff water.

FIRST AID

  • Medical problems take priority over radiological concerns.
  • Use first aid treatment according to the nature of the injury.
  • Do not delay care and transport of a seriously injured person.
  • Give artificial respiration if victim is not breathing.
  • Administer oxygen if breathing is difficult.
  • In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
  • Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed.
  • Injured persons contaminated by contact with released material are not a serious hazard to health care personnel, equipment or facilities.
  • Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and prevent spread of contamination.
