Guidance on hazardous dust for employers and companies
- The employer has legal duties under the ATEX 137 Directive to conduct a risk analysis on his processes (which include cleaning!) and to then select ATEX approved equipment intended for use in high risk areas.
- The employer also has duties under the Dangerous Substances and Explosive Atmospheres Regulations 2002 that specifically include implementing control measures and providing equipment which reduce the quantity of dangerous dusts and prevent explosive atmospheres.
- If the Ocupational Exposure Llimit (OEL) is exceeded then the health of the worker is threatened and the employer may well be in breach of the law if not complying with the current EH40 requirement. Employers are advised to keep up to date copies of EH40 plus any EH40 supplements.
- ATEX Certified vacuums must be maintained in a regular cycle as defined by the ATEX Directive. The maintenance is mandatory in order to preserve the declaration of conformity of the machine.
- R&S Industrial Cleaning Equipment can provide full servicing and calibrations on all ATEX Type 22 vacuums to ensure that you remain
