The Usage andmaintenancemethods of Portable Gas Detectors
In petrochemical enterprises,entering confined spaces for operations is frequent,withmany hazardous factors and the risk of personal injury and death accidents.Therefore,petrochemical enterprises require obtaining a work permit before entering confined spaces.One of the important criteria for determining whether entry is allowed is to detect the content of combustible gases,toxic gases,and oxygen in limited spaces,and the completion of this detection ismostly achieved using portable gas detection alarm devices.This article introduces the common faults andmaintenancemethods of portable gas detection and alarm devices.
