First Aid Measures

Ingestion

Never give anything by mouth to an unconscious person. Get medical aid. If conscious drink water, then induce vomiting. If unconscious, immediately take victim to a physician and do NOT attempt to induce vomiting.

Inhalation

Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.

Skin

Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists.

Eyes

Exposure Controls/Personal Protection

Personal Protection

Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.

Respirators

Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.

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.

Exposure limit(s)

TLV (as TWA): ppm; 10 mg/m3 (ACGIH 1995-1996). OSHA PEL: TWA 15 mg/m3 NIOSH REL: TWA 10 mg/m3 NIOSH IDLH: 2000 mg/m3
