FIRE AND EXPLOSION HAZARD DATA

Fire: Not combustible, but substance is an oxidizer and it’s heat of reaction with reducing agents or combustibles may cause ignition.

Explosion: Strong oxidants may explode when shocked, or if exposed to heat, flame, or friction.

Fire Extinguishing Media: Use any means suitable for surrounding fire.

Special Information: In case of fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode.

HEALTH HAZARD DATA

Inhalation: Moderately hazardous. Coughing, sneezing and breathing difficulty may be expected, and damage to kidneys and liver may occur after continued exposure.

Ingestion: Toxicity rating is not high due to low absorption rate of soluble uranium compounds. However, GI discomfort with vomiting and diarrhea may follow sizeable ingestions. Kidneys and liver may be damaged as well.

Skin: Mildly irritating. Reddening and possible soreness may be experienced.

Eye: Absorption of U salts has been reported. Irritation with reddening of the eye surfaces, pain and partly impaired vision are symptomatic.
