COSHH Regulations 2002 & HSG258
COSHH applies to a wide range of substances which have the potential to cause harm to health if they are ingested, inhaled, or are absorbed by, or come into contact with, the skin, or other body membranes. Hazardous substances can occur in many forms, including solids, liquids, vapours, gases and fumes. A substance hazardous to health need not be just a chemical compound, it can also include mixtures of compounds, micro-organisms or natural materials, such as flour, stone or wood dust.
Dust of any kind can also become a substance hazardous to health under COSHH when it is present at certain concentrations in the air.
In simple terms, employers must assess the risks and put measures in place to prevent or control exposure.
Impact can help to control exposure at source with the design and installation of local exhaust ventilation systems.
Once installed we can then provide regular thorough examination and testing as required by the Regulations to ensure that the controls remains effective.
This guidance focuses on the design of new local exhaust ventilation (LEV) equipment. It also describes the principles of deciding on, designing, commissioning and testing effective LEV. This guidance is written for employers who use or intend to use LEV. The guidance will also help suppliers of LEV, managers, trade union and employee safety representatives.
All of these groups need to work together to provide, maintain and use effective LEV and to reduce exposure from the inhalation of hazardous substances. The guidance contains information about the roles and legal responsibilities of employers and suppliers; competence; principles of good design practice for effective LEV hoods and their classification; ducts, air movers; air cleaners; and system documentation – with checking and maintenance schedules and the marking of defective equipment. It also includes guidance on the specification of LEV; commissioning; zone marking; the user manual and logbook; testing and hood labels.
Impact have years of experience in both designing and installing and testing LEV systems. Our engineers are also trained to BOHS P601 or P602 (the training standard approved by the British Occupational Hygiene Society).
