LEV Testing

Why should I bother with LEV?

The law says you must control the risks from these

substances (the Control of Substances Hazardous to

Health (COSHH) Regulations). Installing LEV may help

you to do this.

For more information about other ways of eliminating or

reducing airborne contamination at work look, at HSE’s

COSHH website, hse.gov.uk/coshh.

A guide to local exhaust ventilation (LEV)

Ref Code: HSG258

The book above provides guidance on the supply of local

exhaust ventilation (LEV) equipment. It describes the

principles and good practice of deciding on, designing,

commissioning and testing cost-effective LEV.

The guidance is written for the suppliers of LEV goods

and

services, but will also be helpful for employers and

managers in medium-sized businesses, and 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 inhalation of

hazardous substances.

The book contains information about the roles and

legal responsibilities of suppliers and of their clients as

employers; 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; the

supplier’s quotation; commissioning; zone marking; the

user manual and logbook; testing and hood labels.
