Hi All,
I appreciate the risks when cutting, drilling, breaking etc matrials that will produce silica dust, however what are the risks from handling equipment which has dried concrete upon it, which could then transfer to clothes in dust form?
Is this a significant risk? I appreciate this is a general question and I don't have numbers at the moment just looking at gaining an understanding. A lot of people who work on building sites or in the trade wash their own clothes, so looking at this from a 2nd hand risk.
Thank you

Silica dust is a risk to if it inhaled but the level of risk depends on a whole load of factors including the type of silica dust (crystalline or amorphous) size of particles( respirable, inhalable) and how it is being created (machine cutting as general rule creates more dust and spreads it further than hand tools). What are you doing to the concrete? Look at this and if you are concerned you may have to do some actual measurement of the actual dust levels that workers are being exposed to. You will probably need to consult with an Industrial Hygienist See http://www.hse.gov.uk/construction/healthrisks/cancer-and-construction/silica-dust.htm for more information
