Description

Dibutyltin oxide (Bu2SnO, C8H18OSn, CAS registry No. 818-08-6) is a white fine powder. Its flash point is 81-83 °C. The solubility of HNQ is 4.0 mg/L in water at 20 °C. It is flammable when exposed to flame. It can react with oxidizing materials. To fight fire, use dry chemical, fog, CO2. When heated to decomposition, it emits acrid smoke and irritating fumes.

Use water spray, powder, carbon dioxide.

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

Cool. Separated from food and feedstuffs, oxidants and bases. Provision to contain effluent from fire extinguishing.

A harmful concentration of airborne particles can be reached quickly when dispersed.

The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the nervous system. This may result in impaired functions. Exposure could cause death.

NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Prevent build-up of electrostatic charges (e.g., by grounding).

AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!

Use local exhaust or breathing protection.

Protective gloves.

Wear face shield or eye protection in combination with breathing protection.
