My extraction system is not very old, do I need it tested?Yes. The frequency of testing will depend on the processes you have but most systems need testing at least once in every period of 14 months. When it is fitted you need to have an initial test and a manual. The data from this test is used as a benchmark for future tests.
Who can I get to test my Extraction System?Testing must be carried out by a “competent person” as shown by them having appropriate qualifications. The BOHS “P601 Initial Appraisal and thorough Examination and Testing” appears to be the most directly relevant but qualifications from BOHS, CIBSE1 and UKAS2, may be acceptable. Companies with a background in various industries may offer this service, but it is probably best to use somebody with experience within the dental industry.
I never received a manual with my system, where can I get one?Remember, your system may have been supplied before these requirements existed your original supplier is probably the best starting point or discuss with the person doing your testing.
I am self-employed and work alone; do I need to have my extraction tested?Yes, the responsibilities of the self-employed, with regard to LEV systems, are the same as for employers. Under the Health and Safety at Work etc Act 1974 (the HSW Act), every employer has health and safety duties to themselves, their employees, and other people who may be affected by the way they carry out their work (‘conduct their undertaking’).
I don’t have any extraction fitted; I don’t think I need it.Under the Health and Safety at Work etc Act 1974 (the HSW Act), every employer has health and safety duties to themselves, their employees, and other people who may be affected by the way they carry out their work (‘conduct their undertaking’). They must take measures to ensure that their workplace is safe and there are effective measures to exposure to airborne particles. LEV (extraction) is one option, and while other options are not specifically excluded, it may be difficult to justify them as adequate.
Can I test it myself?It must be tested by a competent person who is suitably qualified as shown by them having the appropriate qualifications.
How much will it cost?This will depend on the size of your laboratory, the type and age of the equipment. As an indication, for small to medium sized laboratories it may need 1 day of a engineers time to perform the testing and prepare the report. For a medium to large laboratory is may require 2 days. Producing the initial test and manual may take longer.
What happens if it fails?You will need to carry out remedial work in a reasonable timeframe to ensure that the workplace is safe. It will depend on the test result what action needs to be taken.
Do I need to keep records?The person carrying out the thorough examination and test should provide a record which needs to be kept for at least 5 years.
I fitted extraction but one of my employees doesn’t use it.Employers must assess the degree of exposure and the risks to their employees, devise and implement adequate control measures, and check and maintain them. Employees must use these control measures in the way they are intended to be used and as they have been instructed.
Where can I get further information?A guide to Local Exhaust ventilation (LEV) called Controlling airborne contaminants at work is available from the Health and Safety Executive. 1Chartered Institution of Building Services Engineers2United Kingdom Accreditation Service
