Safety information
The updated Control of Substances Hazardous to Health
Regulations 1st October 2012 now also targets to reduce
the risks associated with silica, wood and gypsum dusts.
Construction workers are one of the at- risk groups within
this because of the dust that they breathe: silica dust is
not just a nuisance; it is a real risk to your lungs!
Silica is a natural mineral present in large amounts
in things like sand, sandstone and granite. It is also
commonly found in many construction materials such as
dust (also known as Respirable Crystalline Silica or RCS)
during many common tasks such as cutting, drilling and
silica can lead to the development of:
• Lung cancer
• Silicosis
• Chronic Obstructive Pulmonary Disorder / Chronic
obstructive pulmonary disease (COPD)
the development of Asthma. The risk of lung disease is
linked to people who regularly breathe construction dust
over a period of time, not on the odd occasion.
To protect the lung, the COSHH Regulations sets a limit
on the amount of these dusts that you can breathe (called
a Workplace Exposure Limit or WEL) when averaged
over a normal working day. These limits are not a large
amount of dust: when compared to a penny it is tiny – like
a small pinch of salt:
This limit is the legal maximum; the most you can breathe
after the right controls have been used.
HOW TO REDUCE THE AMOUNT OF DUST?
a) Reduce the amount of cutting by using the best sizes
of building products.
