Combustion products
Fire may produce irritating, corrosive and/or toxic gases.

Health.
Exposure effects
Significant ingestions or dermal exposures can be associated with weak, rapid pulse, cyanosis and abnormally low blood pressure. The patient may present with reduced body temperature, elevated body temperature or normal body temperature. Headache, lethargy, restlessness, weakness, CNS irritation, and/or seizures may occur with long term or repeated exposures. There is insufficient information concerning the reproductive effects of borates in humans. Adverse testicular effects and infertility have been reported in animals. <br>There have been limited animal studies which suggest decreased ovulation, fetotoxicity and developmental defects may occur with very high exposure levels. Maternal toxicity was present in some studies.
   Ingestion
Nausea, vomiting, and diarrhea are common. The vomitus and feces may be blue-green in color. Hemorrhagic gastroenteritis can occur.
   Inhalation
Inhalation of material may be harmful.
   Skin
The oral mucosa, lips and throat may be red. Erythematous rash with desquamation (cooked lobster syndrome) may develop on the palms, soles, and buttocks. A generalized rash has also been reported.
   Eyes
See Skin.

First aid
 
   Ingestion
Seek medical assistance.
   Inhalation
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
   Skin
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. Observe for systemic effects which chiefly occur from chronic skin exposure, or application of borates to denuded skin. Treatment should include recommendations listed in the oral exposure section when appropriate.
   Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
