Using PIDs in confined spaces.

The industrial environment has changed substantially since OSHA first defined confined space entry (CSE) regulation in the late '70s, and gas detection regulation has not kept pace. The standard four-gas monitor is simply insufficient protection from the many--now common--toxic gases and vapors that are major constituents or byproducts of modern industrial processes. Monitors that measure only O2, LEL, CO, and H2S are letting common, devastating toxins slip through the safety net, making them insufficient to the task and exposing workers, families, and communities to unnecessary illnesses and deaths.
