Description of key information

The flammability limits of 1,1,1 -trichloroethane are reported to be 7.5 to 12.5 % in air (ATSDR 2006)

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

The flammability limits of 1,1,1 -trichloroethane are reported to be 7.5 to 12.5 % in air (ATSDR 2006).

As 1,1,1 -trichloroethane is liquid at room temperature no further testing is required as the key parameter for a liquid is the flash point.

Justification for classification or non-classification

As no flash point was observed (see section 4.11) 1,1,1 -trichloroethane should be regarded as "non flammable".
