12. LEV DATA
It is advised that anyone responsible for this equipment is aware of the risks associated with occupational dust exposure.
Make sure that this Booth is risk assessed and complies with COSHH regulations (Control Of Substances Hazardous to
Health), or alternatively the equivalent local regulations. This Booth product is LEV Compliant, so this may help your
organisation satisfy regulations.
For more information on reducing airborne dust or contamination consult your equivalent HSE website. For the UK this is;
For the US it is;
When this Booth unit arrives with you it will have been fully tested at the factory along with a standard extractor & a
length of ducting.
All individual items are LEV compliant, but correct assembly & installation must take place (by a LEV service provider) to make
a fully compliant system. It is recommended that a full commissioning report is obtained prior to system use.
LEV Test Procedure
Once the Booth has been installed it should be tested for LEV compliance (if applicable). The following test procedure will
guide the LEV service provider into making a full, true & correct commissioning report.
1)
Ensure that the Booth is installed as per section 7. Check all bags, filters & hoses are attached & that air is free to
move throughout.
2)
When entering the Booth, the extractor should start & the light should illuminate. These functions are operated by
the roof mounted PIR. The black cleaning nozzle will only work once the extractor & light are operational.
Check, with an anemometer, that the velocity through the front air inlet is at or near to 9m/s. This check should be
completed with all airways open & the door fully closed.
Visually check the interior pressure gauge, it should read close to 0.6kPa & be well in the green part of the gauge
legend.
3)
Press the touch switch to operate the Cleaning Station dust removal gun. This should run for 30 seconds & then switch
off automatically. The Cleaning Station should also be able to be switched on & off by pressing the touch switch
repeatedly. A total pressure measurement should be taken on the Cleaning Station gun, the pressure should read near
t
o 60”Wg (or 2 psi).
