Why is it important to thoroughly test any confined space?

RegSense Confined Spaces Safety & Health Confined Space Hazards Construction Safety General Industry Safety Permit-Required Confined Spaces Best Results FAQ English Focus Area USA

Testing must be done at all depths because some gases are heavier than others and gases are not uniformly mixed within a confined space. Air sampling should be done in four-foot increments vertically and horizontally, including corners and low spots, to ensure that all potential hazards are identified. Make sure that you allow time to accommodate sampling speed and detector response.
