This HSE approved method describes a procedure for the measurement of time-weighted (TWA) average concentrations of water-mix metalworking fluid originating from metalworking machine operations. The method is only suitable when the machine sump fluid (liquid circulating in the machine) contains an element which is unlikely to emanate from a source other than the water or…

This HSE Guidance leaflet aims to help employees who work with metalworking fluids understand the main risks to their health. It contains general advice on the precautions which they and their employers can take to avoid these risks. Full leaflet can be downloaded by clicking on the URL below:-
The full title of this HSE research Report is in fact “Visualisation & Control of Solder Fume Exposure – a Quantitative Assessment of LEV Effectiveness”. Published in 2011 by HSE, the document was prepared by HSL. From the introduction to the Research Report:- “Colophony or Rosin Based Solder Flux Fume is a known cause of…
Whilst not focused solely on the exposure aspects/LEV areas of welding etc, this HSE Guidance leaflet is still very useful for anyone who uses compressed gases for welding, hot cutting and similar processes. It describes the hazards associated with portable oxy/fuel gas equipment and the precautions for avoiding injury and damage to property.
Occasionally there may be a need to measure aerosol particulates in air and there are instruments to do this ….. but they work on two fundamentally different ways. This article by TSI guides you through the differences and might assist you to select the best option for your application. The article provides a basic understanding…
Building Bulletin 88 (Fume Cupboards in Schools) has been replaced by a new document G9 Fume Cupboards in schools, published by CLEAPSS. This updated version has new information regarding LEV testing and the replacement of filters. Regarding LEV testing it specifies: • carrying out additional face velocity tests with the sash at 200mm to ensure…
Excellent guide from CLEAPSS to assist (in particular) schools and colleges in the selection process for Fume Cupboards. Simple straight-forward information sheet. Interestingly advises minimum face velocity to be 0.3 m/s but then goes on to state “ideally 0.4 to 0.45 m/s”
Very useful guide, clearly set out and with simple but effective diagrams from the Filtration Group. This information sheet looks at ATEX compliant filters for removing dusts. Click on the URL link below to be able to download a pdf copy:-
So you’ve passed the P601 or P604 exam, congratulations! The next step is to submit two LEV Thorough Examination and Test Reports. It can be difficult to know where to begin when it comes to submitting two LEV Thorough Examination and Test. This template has been developed over the years with experience of mentoring Oxyl8…
