hot work permit in french

A hot work permit is a written authorization from the employer to perform operations capable of providing a source of ignition [1]. This includes activities like riveting, welding, cutting, burning, and heating [1].

Here's what you need to know about hot work permits, based on Canadian regulations:

1. When Required: A hot work permit is required when hot work is conducted on or near a covered process [2] or in a hazardous location, or an area where an explosive atmosphere may exist [3].
2. Conditions: Before hot work begins, a qualified person must determine that the work can be performed safely [4]. Hot work should not be performed in a hazardous confined space that contains an explosive or flammable hazardous substance in a concentration in excess of 10 % of its lower explosive limit, or oxygen in a concentration in excess of 23 % [4].
3. Safety Measures: Implement procedures to ensure continuous safe performance of the hot work [3]. Clear the hot work location of combustible materials or suitably isolate them [3].
4. Atmospheric Testing: Testing should show that the atmosphere does not contain a flammable substance in a mixture with air, in an amount exceeding 20 percent of that substance's lower explosive limit for gas or vapours, or the minimum ignitable concentration for dust [3]. These tests should be repeated at regular intervals appropriate to the hazard associated with the work being performed [5].
5. Fire Protection: A qualified person must patrol the area surrounding the hazardous confined space and maintain a fire-protection watch in that area until the fire hazard has passed [4]. Emergency equipment must be provided in the area [4].
