BS EN 45544-4:2016
However, two basic measurement tasks can be identified and they form the framework of the new standards: Procedures for workplace exposure measurements, are an important part of the process of exposure assessment, which itself is required to be carried out under national laws and regulations3.
Over the last 4 years in GB, there were between deaths p. Factors affecting the choice of VOC sensor. Detectors for general gas detection are subject to performance requirements for the various tests comparable with those for flammable gas detectors c.
It should be noted that the same detector may be used for general gas detection applications EN and exposure measurements EN The measuring range is defined by the manufacturer. For undated references, the latest edition of the reference document including any amendments applies.
Latest version of Dust Detective Enclosure improves It is applicable to apparatus in which the sensor automatically generates eh electrical signal when gas is present.

The alarm set points of the detector should be set specifically for its application. Outstanding export success recognised with UK trade Oct 10 Read Worldwide Standards We can source any standard from anywhere in the world. For occupational exposure measurement, the performance requirements are focused on uncertainty of measurement of gas concentrations in the region of Occupational Exposure Limit Values Enn. It should be noted, however, that for gases that sorb strongly on the sensor and sampling lines eh.
These are currently the main workhorses for general gas detection in the workplace, especially for use in confined spaces together with flammable gas and oxygen sensors in multigas instruments.
General requirements and test methods EN They have now recently been comprehensively revised: However, for some critical applications e. Air quality networks – simplifying source appor Occupational Safety and Health: Specific requirements relating to the use of various types of measuring procedures and measuring devices for all types of chemical agent including direct-reading instruments for gases ENthe subject of sn article, are referenced in EN ENi.
Confined Spaces Regulations Frequent false alarms can lead to alarms being ignored, leading to complacency and possibly a potentially dangerous escalation of a toxic gas release. You may find similar items within these categories by selecting from the choices below:. Performance requirements for apparatus enn for exposure measurement. BS EN Workplace exposure.

I have annotated in Table 2 below some brief information regarding the detectable gases and usage of the 11 detector types. Toxic gas detectors can reduce risk in various ways depending on the type of detector and how it is used.

New nitrate monitor lowers costs Dec 17 Read However, for most chemical agents the limit values have not been harmonized, therefore a reference value standard test gas concentration is used instead of the limit value for the performance tests in EN Electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours Performance requirements for apparatus used for exposure measurement.
If detectors for gases other than those listed in the table in EN are required to be tested, then values for the standard test gas concentration and lower limit of measurement, can be agreed between the manufacturer and the test laboratory, bearing in mind any limit values, should they exist.
Nov 06 Read Guide for selection, installation, use and maintenance. The procedures used for such measurements should give reliable and valid results, so that when compared with occupational exposure limits5, a correct decision can be made, for instance, as to whether the exposure level is acceptable or control measures e.
