Gas Detectors (Portable)
When using portable gas detectors:
Use portable gas detectors for dangerous and confined spaces.
- Use and maintenance on portable gas detectors should be performed only by competent persons.
- Use manufacturer's recommendations, approved calibration kit, and daily bump test when calibrating gas detectors.
- When used in confined space atmospheric testing, portable gas detectors should have appropriate auxiliary pumps and wands.
- Before issuing confined space permits or safe welding/burning permits, atmospheric testing or sampling should be performed in a confined space.
- When working in confined spaces or hot work areas, continuous monitoring of the atmosphere is required. Documentation is required at 15 minute intervals.
- Portable gas detectors should be calibrated using an external service provider at least every 90 days. Ensure a current inspection sticker (with date) is attached.
