[Fire Fighting]

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.

Administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.

If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention.

Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. Dermatitis - is usually controlled by removal of the offending agent, but may occasionally require a steroid cream.

No special requirements. Good housekeeping dictates that containers should be kept closed when not in use to minimize contamination. Keep away from acids.

Signs and symptoms of excessive exposure may be anaesthetic or narcotic effects.

Dermatitis has been reported by several authors due to garments containing rubber contaminated with mbt or contact with oil containing mbt. The compound itself is not highly irritating.

May cause slight transient eye irritation due to alkaline nature of material.

Amounts swallowed incidentally are not likely to cause injury apart from mild alkaline effects.
[Personal Protection]

Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
