GB/T 46692.2-2025 Gas detectors for workplace atmospheres—Part 2:Selection,installation,use and maintenance of detectors for toxic gases
Abstract
This document provides guidance on the selection, installation, use, and maintenance of electrical equipment for measuring toxic gases and vapors in workplace environments.
The primary purpose of these devices is to ensure the safety of people and property by displaying the concentration of toxic gases or vapors and warning of their presence.
This document applies to continuous sensing detectors with indication, alarm, and/or other output functions, which indicate the presence of toxic gases or vapors in the environment (their sensors generate electrical signals when gases are present) and, in some cases, automatically or manually trigger protective measures.
The devices covered in this document include fixed, mobile, and portable detectors.
This document covers the equipment defined in GB/T 46692.1, and also provides useful information for equipment not covered in GB/T 46692.1.
