Abstract
In the specification and drawings, an isolation enclosure and method for conducting hot work is described and shown with an enclosure; a negative pressure atmosphere within the interior of the enclosure; a hot work apparatus operable outside of and adjacent to the enclosure; and a detector located so as to be capable of detecting the presence of combustible gas within said enclosure. A method of conducting hot work is also described and shown.
Claims4
A method of conducting hot work comprising:
- a. producing a negative pressure atmosphere within an interior of an enclosure;
- b. monitoring for the presence of combustible gas within the interior of the enclosure;
- c. conducting hot work outside of and adjacent to the enclosure;
- d. shutting down the hot work in the event that the presence of combustible gas is detected within the interior of the enclosure;
- and
- e. shutting down the hot work in the event of a loss of the negative pressure atmosphere within the interior of the enclosure.
A method of conducting hot work comprising:
- a. producing a negative pressure atmosphere within an interior of an enclosure, wherein said producing a negative pressure atmosphere within the interior of the enclosure further comprises transferring air from the interior of the enclosure to the exterior of the enclosure;
- b. monitoring for the presence of combustible gas within the interior of the enclosure;
- c. conducting hot work outside of and adjacent to the enclosure;
- d. shutting down the hot work in the event that the presence of combustible gas is detected within the interior of the enclosure;
- e. stopping said transferring air from the interior of the enclosure to the exterior of the enclosure in the event that the presence of combustible gas is detected within the interior of the enclosure;
- f. continuing said monitoring for the presence of combustible gas within the interior of the enclosure;
- and
- g. restarting said transferring air from the interior of the enclosure to the exterior of the enclosure in the event that a level of combustible gas within the interior of the enclosure reaches a predetermined level.
A method of conducting hot work comprising:
- a. producing a negative pressure atmosphere within an interior of an enclosure, wherein said producing a negative pressure atmosphere within the interior of the enclosure further comprises transferring air from the interior of the enclosure to the exterior of the enclosure;
- and wherein said transferring air from the interior of the enclosure to the exterior of the enclosure further comprises storing the air transferred from the interior of the enclosure to the exterior of the enclosure in a container;
- b. monitoring for the presence of combustible gas within the interior of the enclosure;
- c. conducting hot work outside of and adjacent to the enclosure;
- and
- d. shutting down the hot work in the event that the presence of combustible gas is detected within the interior of the enclosure.

- c. conducting hot work outside of and adjacent to the enclosure;
- d. shutting down the hot work in the event that the presence of combustible gas is detected within the interior of the enclosure;
- and
- e. forming the enclosure around a combustible gas releasing structure.
