- Solkane 141b has no flash point. For this reason, as in this respect comparable liquids such as for example trichloroethane and methylene chloride, it is not subject to the Flammable Liquid's Regulation .
- Air-vapour mixtures comprised of between 5.6 and 17.7% by volume (the explosion limits) are flammable. However the minimum energy necessary to initiate ignition is 20 Joules (in comparison to 0.001 Joule for acetone).
- Solkane 141b is not categorized as toxic according to the Dangerous Substances Regulations (Gefahrstoffverordnung). Solvay provisionally recommends a maximum exposure limit of 500 vol-ppm (8 h/d, 40 h/w).
Storage and handling
Solkane 141b must be stored in a cool and well ventilated area; direct exposure of the containers to sunlight must be avoided. Due to the low boiling point of Solkane 141b, there may be a slight, normal over-pressure in the packagings; care must, therefore, be exercised when opening them. Solkane 141b must be kept in a tightly closed container. Humidity and rust must be avoided to ensure optimum stability of the product.
Solkane 141b is not subject to any transport regulation.
It can be handled without risk with the normal precautions. Solkane 141b is slightly irritating to the skin, the eyes and the digestive mucous membranes.
