Workplace atmospheres. Electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours - Performance requirements for apparatus used for general gas detectionWhat is BS EN 45544 3 Workplace air about? BS EN 45544 3 is the third part of the multi series standard that specifies the performance requirements for electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours in workplace atmospheres. BS EN 45544 3 is applicable to apparatus used for general gas detection. EXAMPLE Safety warning and leak detection are examples of general gas detection. Who is
