With today’s portable gas meters becoming more advanced, confined space entry personnel are becoming more relaxed – assuming that monitor advancements will provide better protection. Although this may be true to an extent, the meter is only as good as the user’s ability to understand what it’s telling them. Never underestimate the “unknown.” During this session, we’ll emphasize a risk-based approach to evaluating and understanding the chemical hazards you’re working near. We’ll determine what unknown hazards may be present, what it means from an atmospheric testing standpoint and how to properly decide whether it’s safe to enter a confined space.
