Exposure Assessment & Control


Roof tile silica exposure

Reducing exposures to silica in construction

HSL has undertaken research and showed that just cutting two valley roof tiles in each daily shift (about fifteen minutes of work in eight hours) resulted in the operator being exposed to levels above the occupational exposure limit for respiratory crystalline silica (RCS). Colleagues working close by were also placed at risk.

Novel research better characterises risk from chromium exposures

Urine testing is currently used to assess uptake of chromium in workers by all routes, including ingestion by hand to mouth contact.  However the current test can only measure total chromium and this does not reflect the toxicities of different forms of chromium. 

 

A new technique looking at exhaled breath condensate allows us to measure the carcinogenic form, hexavalent chromium, specifically.  This should result in better insights into exposure scenarios and how best to control them.

Better assessing chromium exposure

Isocyanate skin absorption

Isocyanates can be absorbed through the skin

HSL will be attending Occupational and Environmental Exposure of Skin to Chemicals (OEESC) Conference in Manchester (19-21 September 2016)Kate Jones will be talking about dermal uptake of isocyanates – examples of where significant skin absorption have been observed include laying of floor screeds and the use of isocyanate-based adhesive.  


See how a change in glove regime can make a difference.
