SMEs need better occupational health support
The work of occupational health physicians is highly rated by organisations, but small and medium-sized businesses have little or no access to their support, according to a new HSE report.
New initiative to improve safety in waste industry
The Environmental Services Association (ESA) is launching its Accident Reduction Charter as a major new initiative to improve the health and safety performance in the waste management industry.
Crystalline silica is a naturally occurring mineral found in almost all types of rock, sands, clays, etc and in building materials made from these materials such as bricks, tiles and concrete.
The HSE estimates that at least 100,000 workers are exposed to dust containing respirable crystalline silica on a regular basis in a diverse range of industries including mining, quarrying, brick/tile and ceramic manufacture, construction, foundries and stone-masonry.
Long-term exposure to dusts containing respirable crystalline silica can lead to the development of silicosis, a slowly developing irreversible lung disease.
Heavy and prolonged exposures under conditions that are sufficient to cause silicosis can also lead to an increased risk of lung cancer.
Evidence suggests that a WEL of 0.1mg.m-3 for crystalline silica would in the long-term, considerably reduce the risk of workers developing silicosis.
The consultation document can be found on the HSE's website.
Comments can be sent to the HSE by 13 March 2006.
The HSC's proposal recommends a reduction from the current WEL of 0.3mg.m-3 for respirable crystalline silica to a new WEL of 0.1mg.m-3 (measured as an eight-hour time weighted average).
If the proposal were to be agreed, the HSE would bring the new WEL into force in 2006.
A new WEL set at 0.1mg.m-3 would be accompanied by practical advice on how to control exposures to respirable crystalline silica in the workplace.
The consultation period will be 15 weeks from the day of publication of the consultation document.
