WORKPLACE TOXIC GAS DETECTORS - MAJOR REVISION OF STANDARDS

摘要

Toxic gas detectors perform a valuable role in the workplace by helping to reduce the risk of ill-health and death which can arise from exposure to toxic gases and vapours. An important consideration in their use is the availability of gas detector standards. These help to reassure and guide the user by setting a minimum standard so that practitioners can choose a suitable and reliable detector that is fit for purpose, and use it effectively throughout its working life. A series of European standards for gas detectors (EN 45544 Parts 1-4) were originally published over 15 years ago to address this need. They have now recently been comprehensively revised: 1. EN 45544-1 Workplace atmospheres. Electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours. 1.1 Part 1: General requirements and test methods. (to evaluate the performance of personal, portable, transportable and fixed detectors) Part 2: Performance requirements for apparatus used for exposure measurement. Part 3: Performance requirements for apparatus used for general gas detection.
