Hazards identification

Important hazards Strong oxidizing agent
Adverse human health effects May cause cancer
Toxic if swallowed
Irritant to eyes, skin and mucous membranes

First-aid measures

Eye contact Holding the eyelids apart, flush eyes promptly with copious flowing water for at least 20 minutes.
Get medical attention immediately.
Skin contact Remove contaminated clothing. Wash skin thoroughly with mild soap and plenty of water for at least 15 minutes. Wash clothing before re-use.
Get medical attention immediately.
Inhalation In case of dust inhalation or breathing fumes released from heated material, remove person to fresh air.
Keep him quiet and warm. Apply artificial respiration if necessary and get medical attention immediately.
Ingestion If swallowed, wash mouth thoroughly with plenty of water and give water to drink. Get medical attention immediately.
Notes to the physician Irritant
In case of ingestion induce vomiting in alert patient.
No specific antidote. Treat symptomatically and supportively.

Fire - fighting measures

Flash point None
Flammable/Explosion limits Not applicable
Auto-ignition temperature None
Suitable extinguishing media Water is the most effective extinguishing agent. It should be sprayed on because a jet may throw the powder about.
Fire fighting procedure Move containers from fire area if possible to do so without risk. Cool containers with water spray. Fire fighters should wear full protective clothing and self-contained breathing apparatus (SCBA) in positive pressure mode.
Unusual fire and explosion
hazards Strong oxidizing agent.
Non-combustible but when involved in a fire it liberates oxygen which increases the rate of burning of the combustible materials involved and can cause explosion. Intimate mixtures with powdered materials such as metal powders, sulphur, or carbon may ignite spontaneously or when subjected to friction and burn with explosive violence.
Containers may explode when involved in a fire. Will decompose from ca. 370 Deg.C. releasing poisonous and corrosive fumes of bromine.

Accidental release measures

Personal precautions Wear self-contained breathing apparatus, rubber boots and heavy rubber gloves.
Methods for cleaning up Keep combustibles away from spilled material. With clean shovel place material into clean, dry container and cover. Move containers from spill area and keep for waste disposal. After material pickup is complete, flush remainder with sodium bisulfite solution followed by large amounts of water and ventilate area.

Handling and storage

Handling Keep containers tightly closed.
Avoid producing or diffusing dust into the air.
Avoid bodily contact.
Storage Store in a dry, cool, well-ventilated area away from incompatible materials,Separated from combustible and reducing substances, and powdered metals.

Conditions to avoid Keep away from heat, sparks and open flame Avoid contact with combustibles.
Hazardous decomposition
Hazardous polymerization Will not occur

Toxicological information

Acute toxicity:
- Rat oral LD50 321 mg/kg
Effects of overexposure :
- Ocular Irritant
- Dermal Irritant
- Inhalation Irritant to upper respiratory tract
Difficulty Iin breathing may occur.
Absorption from the lungs may cause symptoms similar to those of ingestion.
- Ingestion The main symptoms of the acute phase of KBrO3 poisoning are vomiting, diarrhea and abdominal pain. Subsequently, headache, dizziness, shock symptoms, deafness, unconsciousness and convulsions are possible.
KBrO3 is a nephrotoxin and an ototoxin. Cardiotoxicity and hepatotoxicity have also been reported.
Methemoglobinemia may also occur.
Chronic toxicity No information available
Mutagenicity Mutagenic by the Ames Test Was found clastogenic in chromosome aberration in vitro test with Chinese hamster cells.
In vivo test with rats demonstrated a dose-response relationship in the increase of incidence of chromosome aberrations in bone marrow cells in both intraperitoneal and oral administrations.
Carcinogenicity IARC Group 2B (animal sufficient evidence, human limited evidence). Potassium bromate induced kidney tumours in rats following administration of relatively high concentraions (250 or 500 ppm) in drinking water. In other laboratory animal species (mice and hamsters), the same significant, typical carcinogenic activity could not be demonstrated.
Not classified as a carcinogen by USA OSHA.
Not included in NTP 9th Report on Carcinogens.

Ecological information

Information on ecological effects
No information available

Disposal considerations

Waste disposal Add material to a large amount of water. Slowly add sodium bisulfite. Acidify if reaction does not proceed spontaneously. Bromine will be liberated during the reaction, which is complete when no bromine remains.
Neutralize and dispose of by flushing down the drain with large quantities of water. Observe all federal, state and local environmental regulations when disposing of this material.
