Atmospheric Testing & Monitoring
Available for MP4 video download by purchasing a corporate or single-site license.
Atmospheric testing and monitoring are used to detect the presence of atmospheric hazards prior to and during confined space entry operations. Testing the atmosphere of a confined space must be done with a calibrated, direct-reading instrument. Any employee who enters the space, or that employee's authorized representative, shall be provided an opportunity to observe the pre-entry atmospheric testing. If a hazardous atmosphere is detected at any time during the entry process, all employees must exit the space immediately.
Topics include what to test confined space atmosphere for, when to test the atmosphere and what to do when a hazardous atmosphere is detected.
