From kitchens to steel work production it is vital to ensure that your LEV is working properly and effectively. Even if you have a LEV in your establishment, do you know that it is working properly? Would you know what to look for if it isn't? This course will aid you through the manufacturing process and on to the up keep and maintenance of the LEV system.

Legal Aspects:

This is looking at all legislation in place for Local Exhaust Ventilation. The Health and Safety at Work Act 1974 (HASAWA) is the Act under which all health and safety regulations are made today and which includes the Control of Substances Hazardous to Health Regulations 2002. They were amended in 2005 and 2014 to give us the "COSHH regulations" that we use today.

Components of the LEV System:

The typical local exhaust ventilation system comprises of a hood, duct, filter, fan and exhaust. The hood is the key design feature and the course looks in great detail at each section of an LEV system.

When it goes wrong:

Very often designs are based upon experience rather than on calculated flow and pressure requirements. Sometimes the designer has not fully appreciated the extent of the emissions and so the hood is inappropriate and will never work. Know what to do in the event of your LEV going wrong.

Management and use of LEV:

The local exhaust ventilation system must be well managed or this could be taken as a failure to comply with the law. The employer has duties explained in HSG 258 for the design, use and maintenance of the system. The process and emissions must be risk assessed and the degree of control by LEV required must be established.
