Personal Exposure Monitoring for Welding Fume and Airborne Particles BS EN ISO 10882-1:2024 provides a recognised methodology for measuring personal exposure to airborne particles generated during welding and allied processes. The standard describes how samples should be collected within the …
HSE Research Report RR1146 investigates airborne emissions generated during the operation of polymer filament desktop 3D printers and evaluates practical control measures for reducing exposure. The research was undertaken following concerns about the increasing use of affordable desktop 3D printers …
This HSE guidance explains the role employees play in ensuring Local Exhaust Ventilation (LEV) systems continue to protect health in the workplace. Whilst employers have legal responsibilities for providing, maintaining and testing LEV systems, workers are often the first people …
The Wake Effect is well known and indeed it is covered at some length in HSE’s Guidance Note HSG258 (Controlling Airborne Contaminants in the Workplace. Have just come across this published research paper from 1994 which considers the Wake Effect …
One of the most common faults discovered during LEV commissioning and Thorough Examination and Test (TExT) is a centrifugal fan that has been wired incorrectly and is rotating in the wrong direction. Surprisingly, when a centrifugal fan runs in reverse, …
EH40 is the Health and Safety Executive’s official publication containing Workplace Exposure Limits (WELs) for hazardous substances used in Great Britain. The document provides occupational exposure limits for hundreds of airborne contaminants including dusts, fumes, fibres, gases, vapours and mists. …
Using Tyndall Lighting to Visualise Airborne Contaminants This HSE presentation explains how special lighting arrangements, commonly known as Tyndall lighting, can be used to make otherwise invisible airborne contaminants visible during LEV assessments and occupational hygiene investigations. The technique uses …
Engineering Controls for UV Ink Printing Operations HSE COSHH Essentials Guidance Sheet P40 provides practical advice for controlling exposure to hazardous substances during wide-format printing processes that use UV-curable inks. The guidance forms part of the COSHH Essentials series and …
This concise but highly informative document, produced by internationally respected industrial ventilation specialist Dr Jeff Burton, provides an overview of the principal United States regulations, standards, consensus documents and recommended practices relating to ventilation systems used for controlling airborne contaminants …
Change in Enforcement Expectations for Mild Steel Welding Fume In February 2019, HSE issued one of the most significant occupational hygiene and LEV-related safety alerts of the last decade. Following new scientific evidence from the International Agency for Research on …
