Special Protective Equipment and Precautions for Fire-Fighters: Move container from fire area if you can do it without risk. Wear self-contained breathing apparatus if necessary. Apply cooling water to sides of containers exposed to flames until well after fire is out. Do not move damaged containers; move undamaged containers out of fire zone. For massive fire in cargo area, use unmanned hose holder or monitor nozzles. Contact the local, State, or Department of Energy radiological response team. Use suitable agent for surrounding fire. Cool containers with flooding  amounts of water, apply from as far a distance as possible. Avoid breathing dusts or vapors, keep upwind. Keep unnecessary people out of area until declared safe by radiological response team.

 

SECTION 6: ACCIDENTAL RELEASE MEASURES

Personal Precautions and Protective Equipment: Avoid contact with eyes, skin and clothing. Avoid breathing dust. Wear respiratory protection, gloves, over garment and goggles. Evacuate personnel to safe areas.

Emergency Procedures/Methods and Materials for Containment and Clean-up: Do not touch damaged containers or spilled material. Damage to outer container may not affect primary inner container. For small liquid spills, take up with sand, earth or other absorbent material. For large spills, dike far ahead of spill for later disposal. Keep unnecessary people at least 150 feet upwind; greater distances may be necessary if advised by qualified radiation authority. Isolate hazard area and deny entry. Enter spill area only to save life; limit entry to shortest possible time. Detain uninjured persons and equipment exposed to radioactive material until arrival or instruction of qualified radiation authority. Delay cleanup until arrival or instruction of qualified radiation authority.

SECTION 7: HANDLING AND STORAGE

Precautions for Safe Handling: Avoid contact with skin and eyes. wash hands thoroughly after handling.

Conditions for Safe Storage: Store in radioactive materials area. Keep container tightly closed. Store separately from incompatible materials. Observe all Federal, State and local regulations when storing this substance.

SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION

Exposure Limits:

URANIUM DiCARBIDE, INSOLUBLE COMPOUNDS (As U):

0.2 mg/m3 OSHA TWA; 0.6 mg/m3 OSHA STEL

0.2 mg/m3 ACGIH TWA; 0.6 mg/m3 ACGIH STEL

0.2 mg/m3 NIOSH Recommended TWA; 0.6 mg/m3 NIOSH Recommended

STEL

Occupational exposure to radioactive substances must adhere to standards established by the Occupational Safety and Health Administration., 29 CFR 1910.96, and/or the Nuclear Regulatory Commission, 10 CFR Part 20. IF purchased by DOE or DOE governed facilities subject to 10 CFR 835. Subject to foreign entity radiation protection regulations.

VENTILATION: At a minimum, provide local exhaust or process enclosure ventilation.

One method of controlling external radiation exposure is to provide adequate shielding. The absorbing material used and the thickness required to attenuate the radiation to acceptable levels depends on the type of radiation, its energy, the flux and the dimensions of the source.

ALPHA PARTICLES: For the energy range of alpha particles usually encountered, a fraction of a millimeter of any ordinary material or a few inches of air is sufficient for absorbency. Rubber, cardboard or any such material will suffice.

BETA PARTICLES: Beta particles are more penetrating than alpha, and require more shielding. Materials composed mostly of elements of low atomic number such as acrylic, aluminum and thick rubber are most appropriate for the absorption of beta particles. With high-energy beta radiation from large sources, Bremsstrahlung (X-ray production) contribution may become significant and it may be necessary to provide additional shielding of high atomic weight material, such as lead, to attenuate the Bremsstrahlung radiation. In the quantities shipped, Certified Reference Materials will not emit significant amounts of beta particles.

GAMMA RAYS: The most suitable materials shielding gamma radiation are lead and iron. Normal and depleted uranium is not normally considered gamma emitters. In the quantity shipped, enriched Certified Reference Materials will pose only a negligible gamma hazard.

EYE PROTECTION: Employee must wear appropriate eye protection that will not allow the introduction of particles into the eyes. Contact lenses should not be worn.

Clothing, glove and eye protection equipment will provide protection against alpha particles.

CLOTHING: Disposable over-garments, including head coverings and foot covering, should be worn by any employee engaged in handling any radioactive substance. These garments are also recommended even if the employee is working with a “glove box” containment system.

In the event of an accident, full protective clothing will be necessary.

GLOVES: Employee must wear appropriate protective gloves to prevent contact with this substance. Used gloves may be contaminated and should be disposed of as radioactive waste.

RESPIRATOR: The following respirators and maximum use concentrations are recommendations by the U.S. Department of Health and Human Services, NIOSH pocket guide to chemical hazards; NIOSH criteria documents or by the U.S. Department of Labor, 29 CFR 1910 Subpart Z.

The specific respirator selected must be based on contamination levels found in the work place, must not exceed the working limits of the respirator and be jointly approved by the National Institute for Occupational Safety and Health and the Mine Safety and Health Administration (NIOSH-MSHA).

URANIUM, Insoluble compounds (As U):

SECTION 11: TOXICOLOGY INFORMATION

URANIUM

Carcinogenicity

Contains a radioactive isotope which may produce cancer and genetic mutation.

IARC: No chemical component of this product present at levels greater than or equal to 0.1% is identified as probable, possible or confirmed human carcinogen by IARC.

NTP: No chemical component of this product present at levels greater than or equal to 0.1% is identified as a known or anticipated carcinogen by NTP.

OSHA: No chemical component of this product present at levels greater than or equal to 0.1% is identified as a carcinogen or potential carcinogen by OSHA.

CARCINOGEN STATUS: Not carcinogenic as a chemical. Ionizing radiation is carcinogenic.

The toxicity of uranium metal has not been quantified. Uranium may be a skin, eye, and mucous membrane irritant, as well as a nephrotoxin. Uranium metal usually does not constitute an external radiation exposure hazard since it emits mainly alpha-radiation at a low energy level. It may constitute an internal radiation hazard if it is absorbed into the body, thus delivering alpha emission onto tissues in which it is stored.

HEALTH EFFECTS

INHALATION

URANIUM

RADIOACTIVE/NEPHROTOXIN. 30 mg/m3 immediately dangerous to life and health.

ACUTE EXPOSURE – Uranium may enter the body through inhalation of fine particles that are approximately 1 micron in diameter. Uranium poisoning is characterized by generalized health impairment. It may cause changes in the kidneys, liver, lungs, and cardiovascular, nervous, and hemopoietic systems, and disorders of protein and carbohydrate metabolism. Symptoms may include oliguria, hematuria, albuminuria, and jaundice.

CHRONIC EXPOSURE – Workers exposed to high average levels of uranium dust in a plant at Oak Ridge have not had increased mortality rates from lung cancer, leukemia, bone cancer, or diseases of the

respiratory and genitourinary systems. Lung cancer in uranium miners is probably the result of inhalation of radon daughters found in these mines. Chronic poisoning gives chest findings of pneumoconiosis, pronounced blood changes and generalized injury. Cancer or lymphatic and blood forming tissues may result. See the following sections regarding the effects of inhalation of an alpha emitter.

ALPHA RADIATION:

ACUTE EXPOSURE – Alpha radiation is densely ionizing with very high energy and will kill cells immediately adjacent to the source of contact. Damaged cells may not recover or be repaired. Alpha emitters may or may not be absorbed, depending on the solubility and particle size. Insoluble compounds may remain at or near the site of deposition, and soluble compounds may rapidly enter the bloodstream. Heavier particles will be brought up to the throat by ciliary action, and may then be swallowed. The lighter particles may be lodged deep in the alveolar air sacs and remain. The damage depends on how quickly they are eliminated, and the susceptibility of the tissue in which they are stored. A single large dose of radiation may lead to increases cancer risk.

CHRONIC EXPOSURE – The effects of chronic exposure by internally deposited alpha radiation is dependent upon the dose and target organ(a). Possible disorders include lung cancer, sterility, anemia, leukemia, or bone cancer.

The delayed effects of radiation may be due either to a single large overexposure or continuing low-level overexposure and may include cancer, genetic effects, shortening of life span and cataracts. Cancer is observed most frequently in the hematopoietic system, thyroid, bone and skin. Leukemia is among the most likely forms of malignancy. Lung cancer may also occur due to radioactive materials residing in the lungs. Genetic effects may range from point mutations to severe chromosome damage such as strand breakage, translocations, and deletions. If the germ cells have been affected, the effects of the mutation may not become apparent until the next generation, or even later.

SKIN CONTACT:

URANIUM

RADIOACTIVE:

ACUTE EXPOSURE – There is no evidence that insoluble uranium compounds can be absorbed through the skin; insoluble salts produced no signs of poisoning after skin contact. Uranium may irritate the skin.

CHRONIC EXPOSURE – Prolonged skin contact with insoluble uranium compounds should be avoided because of potential radiation damage to basal cells. Dermatitis has occurred as a result of handling some insoluble uranium compounds.

ALPHA RADIATION:

ACUTE EXPOSURE – Alpha radiation is not usually an external hazard. However, local damage may occur at the site of a wound. Absorption or penetration through damaged skin may result in increased cancer risk.

CHRONIC EXPOSURE – Prolonged or repeated contact my result in increased cancer risk.

EYE CONTACT:

URANIUM

RADIOACTIVE:

ACUTE EXPOSURE – Dust may be irritating to the eyes. A variety of soluble and insoluble compounds or uranium were tested on the eyes of rabbits. The insoluble compounds caused the mildest degree of injury. The effects of eye contact with any uranium compound tend to be necrosis of the conjunctivae and eyelids, and ulceration of the cornea.

CHRONIC EXPOSURE – Prolonged exposure to uranium may produce conjunctivitis, or the symptoms of radiation injury, such as cataracts. See the following sections regarding the effects of alpha radiation on the eyes.

ALPHA RADIATION:

ACUTE EXPOSURE – Radiation affects the eye by inducing acute inflammation of the conjunctiva and the cornea. The most sensitive part of the eye is the crystalline lens. A late effect of eye irradiation is cataract formation. It may begin anywhere from 6 months to several years after a single exposure. Cataract formation begins at the posterior pole of the lens, and continues until the entire lens has been affected. Growth of the opacity may stop at any point. The rate of growth and the degree of opacity are dependent upon the dose of radiation.

CHRONIC EXPOSURE – Repeated or prolonged exposure to alpha radiation may result in cataract formation, as described above. Of the well-documented late effects of radiation on man, leukemia and cataracts have been observed at doses lower than those producing skin scarring and cancer or bone tumors. The lens of the eye should be considered to be a critical organ.

INGESTION:

URANIUM:

RADIOACTIVE/NEPHROTOXIN

ACUTE EXPOSURE – Feeding studies on animals indicate that insoluble uranium is much less toxic than soluble uranium compounds. Uranium entering the bloodstream will become stored in the bone marrow, but the majority will become lodged in the kidney, which is the major site of toxicity. More than a year and a half are required to rid the body of an accidental high dose of uranium, after which time measurable uranium is present in the bone and kidney.

CHRONIC EXPOSURE – The toxic action of uranium resides more in its chemical action on the renal tubules, rather than radiation effects. Rats injected with uranium metal in the femoral marrow developed sarcomas, whether this was due to metallocarcinogenic or radiocarcinogenic ingestion of alpha emitters. Also see the first aid section for uranium compounds.

ALPHA RADIATION:

ACUTE EXPOSURE – The fate of ingested alpha emitters depends on their solubility and valence.

CHRONIC EXPOSURE – Repeated ingestion of alpha emitters may increase cancer risks.

FIRST AID FOR URANIUM COMPOUNDS: Although chelating agents act on uranium, they should not be used because the increased migrant fraction leads through renal precipitation to a greater kidney burden than would be received if there were no treatment at all; there is thus the risk of serious toxic nephritis. The basic treatment should be administration of a bicarbonated solution given locally and in intravenous perfusion (one bottle of 250 ML at 1.4%).
