When is a Flammable Liquid Not Flammable?

 In Laboratory Services

When it does not sustain combustion.

Imagine not having to ship your product as a Hazardous Material or even as a Limited Quantity.

Often overlooked in the Hazardous Materials Regulations 173.120(3) and the Transportation of Dangerous Goods Regulations 2.18(2)(a) is that a liquid with a flash point greater than 35°C is not included in Class 3 Flammable Liquid if it does not sustain combustion as determined in accordance with the sustained combustibility test referred to in section of Chapter 2.3 of the UN Recommendations – the L.2 Sustained Combustibility test.

Similarly in the Consumer Chemicals & Containers Regulations (CCCR), a combustible liquid (flash point  > 37.8 °C but < 60 º C) may be exempt from the flammable classification if it is composed of 50% or more of water and 50% or less of water-miscible solvents and does not sustain combustion when tested in accordance with the L.2 Sustained Combustibility Test.
