First Aid Measures

Ingestion
Administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
Inhalation
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.
Skin
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.
Eyes
If symptoms develop, immediately move individual away from exposure and into fresh air. Flush eyes gently with water for at least 15 minutes while holding eyelids apart; seek immediate medical attention.

Handling and Storage

Storage
Keep in a cool, dry location in a sealed container.
Handling
No special requirements. Good housekeeping dictates that containers should be kept closed when not in use to minimize contamination. Keep away from acids.

Hazards Identification

Inhalation
Signs and symptoms of excessive exposure may be anaesthetic or narcotic effects.
Skin
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.
Eyes
May cause slight transient eye irritation due to alkaline nature of material.
Ingestion
Amounts swallowed incidentally are not likely to cause injury apart from mild alkaline effects.

Exposure Controls/Personal Protection

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.
Respirators
Respiratory protection is not generally required.
Exposure Effects
Seizures have been reported in animals given 335 mg/kg.
Poison Class
4

Fire Fighting Measures

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.

Accidental Release Measures

Small spills/leaks
Clean up personnel should wear full protective clothing. Do not allow spill material to enter sewers, storn water drains, etc. Do not allow to mix with acids. Soak up spill with nonreactive absorbent material and place in a secure container pending disposal. Wash residue with copious amounts of water, sewer disposal acceptable.

Stability and Reactivity

Stability
No data.
Incompatibilities
Strong oxidizing agents.
Decomposition
Oxides of carbon and sulfur.
