Low Volume High Velocity (LVHV) extraction systems have become increasingly important in controlling dust generated by portable power tools and hand-held processes. By capturing contaminants directly at the point of generation, LVHV systems can significantly reduce worker exposure to hazardous …
When a Demonstration Overwhelms a Fume Cupboard The “Screaming Jelly Baby” experiment is one of the most well-known chemistry demonstrations performed in schools and colleges throughout the UK. The demonstration involves dropping a jelly baby into molten potassium chlorate, resulting …
Understanding the Risks of Exposure to Hexavalent Chromium Chromium and You (INDG346) is an HSE guidance leaflet produced for workers and employers who may be exposed to chromium and chromium compounds during their work activities. While chromium exists in several …
BS EN 12021 is the key European standard specifying the quality requirements for compressed gases supplied for use in breathing apparatus and respiratory protective equipment. The standard establishes limits for contaminants and defines the quality criteria necessary to ensure that …
Measuring the Effectiveness of On-Gun Welding Fume Extraction HSE Research Report RR1010 investigates methods for measuring the capture efficiency of on-gun (on-torch) welding fume extraction systems and proposes a standardised approach for assessing their performance. On-gun extraction systems have become …
Understanding the Occupational Causes of Sinonasal Cancer HSE Research Report RR933 forms part of the Health and Safety Executive’s major research programme investigating the burden of occupational cancer in Great Britain. The report examines occupational exposures associated with sinonasal cancer, …
The Casella Air Sampling Solutions Handbook is one of the most practical introductory guides available for occupational hygienists, LEV professionals and anyone involved in workplace exposure monitoring. The handbook explains the principles of personal and area air sampling and provides …
This SHAPA technical paper provides practical guidance for organisations involved in the design, installation, operation and maintenance of equipment used in potentially explosive dust atmospheres. Originally developed with input from SHAPA members, the Health and Safety Executive (HSE) and the …
LVHV On-Tool Extraction Testing Toolkit This free resource pack has been developed to support LEV engineers undertaking COSHH Regulation 9 Thorough Examination and Test (TExT) assessments of LVHV (Low Volume High Velocity) and on-tool extraction systems. While HSG258 and other …
This short HSE video provides a powerful visual demonstration of how airborne contaminants behave inside a typical spray room. Using artificial smoke and accelerated playback, the video illustrates how contaminants can remain suspended within the workspace long after spraying activities …
