The law is that the employer must maintain LEV system performance and should also arrange a thorough examination and test at least every 14 months. The employer needs to know whether or not an examination has been done or when it’s due, and so do supervisors and operators. Critically, they also need to know when a hood (or LEV system) has failed.

Why did Lev agree to go with CYFI?

Lev had agreed to go with him because he knew the two filled a need in each other. CyFi was like a preacher with no flock. He couldn’t exist without an audience, and Lev needed someone who could fill his head with ideas, to replace the lifetime of ideas that had been taken from him.

Why does my LEV system not work properly?

But as an employer you do by law have to make sure your LEV system keeps working properly. One of main reasons why LEV doesn’t do what it should is because the airflow falls for some reason (eg build-up of material, damage to ducting etc), becomes inadequate and effective control is lost.

When do you remove the failed Lev Hood label?

Once the employer has had the LEV hood or system repaired, a competent person needs to check that it is effective and adequately controls exposure. The ‘Failed’ label can then be removed. Is there an alternative to labels?

What kind of indicator should be fitted for LEV system?

For instance, a manometer, measuring static pressure across the filter unit, can provide sufficient indication, for a simple LEV system consisting of a fan, an air-cleaner (eg filter), a duct and a hood. What sort of airflow indicator should be fitted? It depends on the level of potential health risks.

Do you have a legal responsibility to check your Lev?

You have a legal responsibility to ensure that employee exposure to dust/fumes etc. is minimised and well controlled. LEV is an excellent way of doing this. People who supply, examine and maintain LEV need to be competent otherwise your LEV may not work properly, putting people’s health at risk.

Where do you put the Test record on a Lev Hood?

HSE guidance recommends examiners label each hood with a test record. Alternatively, the test record label could alternatively be placed nearby, for instance, close to the system on-off switch. It should be clearly visible to the supervisor and operators. Do examiners have to put red labels on all LEV hoods that have failed?

How can I tell if my Lev is still working?

To assess if the LEV is still working properly, the examiner ideally needs to know what it was originally intended to do. When you obtained the LEV equipment, the supplier should have tested it on installation (or ‘commissioned’ it) to check it was working effectively and providing the necessary protection, as specified.

What should be included in a Lev Hood report?

With the label should come a short ’emergency’ written report containing a clear description of what’s wrong and a list of practical remedial actions. Once the employer has had the LEV hood or system repaired, a competent person needs to check that it is effective and adequately controls exposure.

Do you have to have airflow indicators for LEV system?

There isn’t a specific legal requirement to have airflow indicators or similar fitted to an extraction. But as an employer you do by law have to make sure your LEV system keeps working properly.
