TLVs for heat stress

This week we’re running the BOHS module M201 Thermal environment and non-ionising radiation (including lighting). This is one of the optional modules and most hygienists will only come across problems related to these topics on rare occasions. Consequently, after the course, it can be difficult to keep up to date with new research and developments.Continue reading “TLVs for heat stress”

Heat stress indices

Assessing the risk from the thermal environment is not easy. One of the main reasons for this is that there are a large number of factors which affect our physiological response to heat. The main ones are Four environmental parameters Air temperature Mean radiant temperature Relative humidity Air velocity And three “human” factors Work rateContinue reading “Heat stress indices”
