Abstract

In the specification and drawings, an apparatus for conducting hot work is described and shown with an enclosure; a hot work apparatus operable within the enclosure; and a detector located exterior of the enclosure, the detector being in detecting communication with the interior of the enclosure, such that the detector detects the presence of a condition within the enclosure. A method of conducting hot work is also described and shown.

Claims

1. An apparatus for conducting hot work comprising:

a. an enclosure;

b. a hot work apparatus operable within said enclosure;

c. a blower assembly in fluid communication with an interior of said enclosure; and

d. a detector located so as to detect the presence of a condition in or near to an air intake of said blower assembly, said detector being in communication with said blower assembly, said detector being isolated from said hot work apparatus.

2. The apparatus of claim 1 further comprising a first controller, said first controller being in communication with said hot work apparatus, said first controller being isolated from said blower assembly.

3. The apparatus of claim 1 further comprising a pressure detector fluidly connected to the interior of said enclosure, said pressure detector being in communication with said hot work apparatus.

4. The apparatus of claim 3 wherein said pressure detector is isolated from said blower assembly.

5. The apparatus of claim 1 further comprising a second controller, said second controller being in communication with said blower assembly, said second controller being in communication with said detector.

6. The apparatus of claim 5 further comprising:

a. a first controller, said first controller being in communication with said hot work apparatus, said first controller being isolated from said blower assembly; and

b. a pressure detector fluidly connected to the interior of said enclosure, said pressure detector being in communication with said first controller.

7. The apparatus of claim 1 wherein said detector comprises a combustible gas detector located so as to detect the presence of a level of combustible gas in or near to an air intake of said blower assembly.

8. The apparatus of claim 7 further comprising:

a. an oxygen detector located so as to detect the presence of a level of oxygen in or near to an air intake of said blower assembly, said oxygen detector being in communication with said blower assembly, said oxygen detector being isolated from said hot work apparatus; and

b. a carbon monoxide detector located so as to detect the presence of a level of carbon monoxide in or near to an air intake of said blower assembly, said carbon monoxide detector being in communication with said blower assembly, said carbon monoxide detector being isolated from said hot work apparatus.
