Potential Health Effects
----------------------------------
Inhalation:
Inhalation can cause severe irritation of mucous membranes and upper respiratory tract. Symptoms may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.
Ingestion:
Causes irritation to the gastrointestinal tract. Symptoms may include nausea, vomiting and diarrhea. May cause abdominal pain, reduced urinary output, low blood pressure, methemoglobinemia, blurred vision, dizziness. Both concentrated potassium bromate and potassium hydroxide can be fatal. Estimated lethal dose of potassium bromate is 4 grams; potassium hydroxide is 5 grams.
Skin Contact:
Causes irritation with redness and pain. Prolonged skin contact may cause burns. May be absorbed through skin.
Eye Contact:
Causes irritation with redness, pain. May cause eye damage.
Chronic Exposure:
For Potassium Bromate: Overexposure may cause kidney damage.
For Potassium Bromide: Repeated or prolonged exposure by any route may cause skin rashes (bromaderma). Repeated ingestion of small amounts may cause central nervous system depression, including depression, ataxia, psychoses, memory loss, irritability, and headache.
For Potassium Hydroxide: Prolonged contact with dilute solutions or dust has a destructive effect on tissue.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems, or impaired liver, kidney or respiratory function, or suffering from debilitation, depression, alcoholism, neurological or psychological disorders may be more susceptible to the effects of this compound.
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person. Get medical attention immediately.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.
Fire:
Not combustible, but substance is a strong oxidizer and its heat of reaction with reducing agents or combustibles may cause ignition. Forms very flammable mixtures with combustible materials and may be explosive if the combustible material is very finely divided. Can be ignited by friction.
Explosion:
May explode when exposed to mechanical shock or friction or can cause explosions with combustible materials. Sealed containers may rupture when heated. Sensitive to mechanical impact.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire. Do not allow water runoff to enter sewers or waterways.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.
Ventilate area of leak or spill. Remove all sources of ignition. Wear appropriate personal protective equipment as specified in Section 8. Isolate hazard area. Keep unnecessary and unprotected personnel from entering. Contain and recover liquid when possible. Use non-sparking tools and equipment. Collect liquid in an appropriate container or absorb with an inert material (e. g., vermiculite, dry sand, earth), and place in a chemical waste container. Do not use combustible materials, such as saw dust. Do not flush to sewer! US Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities. The toll free number for the US Coast Guard National Response Center is (800) 424-8802.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage and moisture. Isolate from any source of heat or ignition. Avoid storage on wood floors. Separate from incompatibles, combustibles, organic or other readily oxidizable materials. Containers of this material may be hazardous when empty since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the product.
Airborne Exposure Limits:
Potassium Bromate:
- AIHA Workplace Environmental Exposure Level (WEEL) -
0.1 mg/m3 (TWA)
Potassium Hydroxide:
- OSHA Permisible Exposure Limit (PEL) -
2 mg/m3 (Ceiling)
- ACGIH Threshold Limit Value (TLV) -
2 mg/m3 (STEL/Ceiling)
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded, a half-face dust/mist respirator may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece dust/mist respirator may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency, or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area.

Hazardous Decomposition Products:
Emits fumes of bromine, potassium oxide, and hyrdrogen bromide when heated to decomposition.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
For Potassium Bromate: Acids, reducing agents, organic material, aluminum, arsenic, calcium hydride, carbon, copper, powder metals, metal sulfides, phosphonium iodine, phosphorus, lead acetate, selenium, and sulfur.
For Potassium Bromide: Strong oxidizers, acids, and bromine trifluoride.
For Potassium Hydroxide: Contact with water, acids, flammable liquids, and organic halogen compounds, especially trichloroethylene, may cause fire or explosion. Contact with nitromethane and other similar nitro compounds causes formation of shock-sensitive salts. Contact with metals such as aluminum, tin, and zinc causes formation of flammable hydrogen gas.
Conditions to Avoid:
Heat, flame, moisture, dusting, sources of ignition and shock, and incompatibles.
