Most manufacturers and safety standards recommend calibrating 4-gas monitors at least every 6 months, with bump testing performed before each use or shift. However, calibration frequency may increase if the monitor has been exposed to high gas concentrations, extreme environmental conditions, physical impact, or if a bump test fails to produce the expected response.
