First Aid Measures | Back to Contents | 【Ingestion】
Administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. | 【Inhalation】
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. | 【Skin】
Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush with running water for at least 20 minutes. | 【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. |
Handling and Storage | Back to Contents | 【Storage】
Keep well closed and in a cool place. | 【Handling】
Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data sheet must be observed. |
Hazards Identification | Back to Contents | 【Inhalation】
Vapors may cause injury, burns, death. | 【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. | 【Ingestion】
Nausea, vomiting, and diarrhea are common. The vomitus and feces may be blue-green in color. Hemorrhagic gastroenteritis can occur. | 【Hazards】
May explode from heat or contamination. May react explosively with hydrocarbons (fuels). May ignite combustibles. | 【UN (DOT)】

Exposure Controls/Personal Protection | Back to Contents | 【Personal Protection】
Wear appropriate protective gloves, clothing and goggles. | 【Respirators】
Wear positive pressure self-contained breathing apparatus (SCBA). | 【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. | 【Poison Class】

Fire Fighting Measures | Back to Contents | 【Fire Fighting】
Small Fires: Use water. Do not use dry chemicals or foams. carbon dioxide or Halon may provide limited control. Large Fires: Flood fire area with water from a distance. | 【Fire Potential】
These substances will accelerate burning when involved in a fire. |
Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Keep away from combustible materials. Avoid contact unless wearing appropriate protective clothing. Stop leak if you can do it without risk. With clean shovel place material into clean, dry container and cover loosely; move containers from spill area. |
Stability and Reactivity | Back to Contents | 【Incompatibilities】
Avoid contact with strong oxidizing agent, fire risk in contact with organic materials forms hydrogen peroxide in the presence of acids. | 【Stability】
Stable as powder stable when kept cool and dry, but decomposes with the liberation of oxygen in warm or moist air. | 【Decomposition】
When heated to decomposition, it emits toxic fumes of disodium oxide. Decomposes in water with the liberation of hydrogen peroxide and then oxygen. | 【Combustion Products】
Fire may produce irritating, corrosive and/or toxic gases. |
