The Control of Substances Hazardous to Health (Amendment) Regulations 2004 (COSHH 2004) will prohibit the supply or use of cement which has a chromium VI concentration of more than 2 parts per million. As well as cement itself, the restriction will apply to a wide range of products that contain cement such as mortars, grouts, tile adhesives etc.
This legislation is being introduced to help prevent allergic contact dermatitis, a potentially serious condition that can lead to permanent disability, which can occur when wet cement containing chromium VI comes into contact with the skin. While construction workers such as bricklayers, tile layers, and workers laying concrete floors are likely to be at most risk, this condition can occur in members of the public who use cement or products containing cement without taking proper precautions.
From 17 January 2005 manufacturers will have to add a reducing agent to their products to bring chromium concentrations down to permitted levels (2 parts per million). In addition, they must provide information on safe shelf life, as the reducing agent is only effective for a limited period. Although virtually all uses of cement are covered by this ban, cement and cement products produced and used in controlled and closed systems are exempt from this restriction.
