Respirable Crystalline Silica

Recent publication:
New analytical technique for
respirable crystalline silica

Peter Stacey (of our Analytical Chemistry team) has published on the potential for Raman spectroscopy to be a viable option for the quantification of the mass of respirable crystalline silica on filters, with a limit of detection approaching 1/10th of that obtained with other techniques. 


The improvement in sensitivity may enable the measurement of particulate in samples from low concentration environments (e.g. inside a mask) or from miniature samplers operating at low flow rates. Follow this link to read the full article. 

Isocyanate Survey

Recent publication:
Isocyanate Survey 

We have recently published a survey of seven workplaces using diisocyanates in different processes (casting, grouting, core making, spray painting, foam blowing, and floor screeding). 


Results showed that there was potential for substantial skin absorption of diisocyanates in certain processes such as floor screeding and foam production. 
Urine sampling is a practical way of monitoring the extent of skin absorption in these processes –
further details are available on our website.

Occupational Hygiene 2017

HSL is presenting at
Occupational Hygiene 2017 

(24-27 April)

HSL will once again be well represented at the BOHS annual conference.  Chris Keen, of HSL’s Occupational Hygiene team will be delivering a presentation on 'Dust exposure associated with industrial cleaning activities'.  

There will be other HSL talks covering Workplace Health Without Borders, wood dust exposure, metal dust exposures in additive manufacturing, a new miniature sampler and improving respirator fit testing.  

We also have an exhibition stand at the event so please come along and have a chat with us if you are attending.
