Smoke testing of asbestos enclosures

As people are aware it is important to undertake smoke testing of your enclosures. People who have not done this before may not be aware of the amount of smoke/fog that is generated inside the enclosure, the visibility can reduce to zero. In one enclosure I tested the other day, the people inside the enclosure could not see their hands (there were no leaks observed so it passed).

It is therefore important that in planning your smoke test you consider:

1. How will you communicate between those on the inside and outside the enclosure?
2. How will those inside know where they are and where an exit is?
3. Can the neg air be turned on to remove the smoke/fog? If so how?

Anything undertaken in the enclosure, while the smoke test is being undertaken, will be undertaken with the assumption that there is absolutely no visibility. Now think of the safety implications of that and plan for it.
