163 Radioactive Materials (Low to High Level
Radiation)
 |
| POTENTIAL HAZARDS |
HEALTH |
*
Radiation presents minimal risk to transport workers, emergency response personnel, and
the public during transportation accidents. Packaging durability increases as potential
hazard of radioactive content increases.
*
Undamaged packages are safe. Contents of damaged packages may cause higher external
radiation exposure, or both external and internal radiation exposure if contents are
released. * Type A packages (cartons, boxes, drums, articles, etc.) identified as
"Type A" by marking on packages or by shipping papers contain non-life
endangering amounts. Partial releases might be expected if "Type A" packages are
damaged in moderately severe accidents. * Type B packages, and the rarely occurring Type C
packages, (large and small, usually metal) contain the most hazardous amounts. They can be
identified by package markings or by shipping papers. Life threatening conditions may
exist only if contents are released or package shielding fails. Because of design,
evaluation, and testing of packages, these conditions would be expected only for accidents
of utmost severity. * The rarely occurring "Special Arrangement" shipments may
be of Type A, Type B or Type C packages. Package type will be marked on packages, and
shipment details will be on shipping papers. * Radioactive White-I labels indicate
radiation levels outside single, isolated, undamaged packages are very low (less than
0.005 mSv/h (0.5 mrem/h)). * Radioactive Yellow-II and Yellow-III labeled packages have
higher radiation levels. The transport index (TI) on the label identifies the maximum
radiation level in mrem/h one meter from a single, isolated, undamaged package. * Some
radioactive materials cannot be detected by commonly available instruments. * Water from
cargo fire control may cause pollution. |
FIRE
OR EXPLOSION |
*
Some of these materials may burn, but most do not ignite readily. * Radioactivity does not
change flammability or other properties of materials. * Type B packages are designed and
evaluated to withstand total engulfment in flames at temperatures of 800 degrees C (1475
degrees F) for a period of 30 minutes. |
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, and control of fire 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. * Isolate spill or
leak area immediately for at least 25 to 50 meters (80 to 160 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 |
*
Positive pressure self-contained breathing apparatus (SCBA) and structural firefighters'
protective clothing will provide adequate protection against internal radiation exposure,
but not external radiation exposure. |
EVACUATION |
Large
Spill: Consider initial downwind evacuation for at least 100 meters (330 feet). |
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 |
*
Presence of radioactive material will not influence the fire control processes and should
not influence selection of techniques. * Move containers from fire area if you can do it
without risk. * Do not move damaged packages; move undamaged packages out of fire zone. |
Small
Fires: Dry chemical, CO2, water spray or regular foam. |
Large
Fires: * Water spray, fog (flooding amounts). * Dike fire-control water for later
disposal. |
SPILL
OR LEAK |
*
Do not touch damaged packages or spilled material. * Damp surfaces on undamaged or
slightly damaged packages are seldom an indication of packaging failure. Most packaging
for liquid content have inner containers and/or inner absorbent materials. * Cover liquid
spill with sand, earth or other noncombustible absorbent material. |
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. * Apply 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. * 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. |
