Course Details

The Control of Substances Hazardous to Health (COSHH) Regulations 2002 state that exposure to hazardous substances must be avoided completely, or adequately controlled where this is not practicable. The Regulations require control measures to follow a strict hierarchy and engineering solutions must be applied for the control of exposure before the use of personal protective equipment is considered. Local Exhaust Ventilation (LEV) systems can provide a very effective means of exposure control and systems of varying complexity may be found in workshops and laboratories.

However, many systems perform badly, often because of poor design, inappropriate modifications and lack of maintenance. Exposure control may be further compromised by lack of training and and misuse by operators.

Training is a legislative requirement and the Safety Office is offering a half day course on Local Exhaust Ventilation Systems. The course will focus on systems found typically in workshops, for activites such as rock grinding, metal cutting, welding, soldering, and woodworking. However the use of fume cupboards and microbiological safety cabinets (also forms of LEV) is covered elsewhere.
