Activated carbon is widely used in industrial air pollution control systems, odour abatement plant, VOC treatment systems, biogas upgrading facilities and LEV filtration systems. Under normal operating conditions it is generally considered a safe and effective filtration medium. However, under …
Fletcher’s Equations for Captor Hoods – Free Excel Spreadsheet and Mobile App Fletcher’s Equations are the methodology recommended by HSE for calculating captor hood performance and effective captor distances. They are widely used by LEV designers, commissioning engineers and TExT …
The IACS Non-Sparking Fan Standard (UR F29) provides guidance on fan construction and material selection where explosive atmospheres may be present. It is frequently referenced when specifying LEV systems for DSEAR-regulated environments. The document outlines acceptable arrangements for preventing frictional …
This Institution of Mechanical Engineers (IMechE) guide provides practical engineering guidance on applying the principle of reducing risks to As Low As Reasonably Practicable (ALARP). The report explains how engineers and duty holders can demonstrate that safety risks have been …
This HSE training video demonstrates how Local Exhaust Ventilation (LEV) can be used to control worker exposure to Metal Working Fluid (MWF) mist generated during CNC machining operations. MWF mist can cause occupational asthma, hypersensitivity pneumonitis, dermatitis and other respiratory …
This HSE guidance provides ten practical noise control techniques that can be applied across a wide range of industries to reduce workplace noise exposure and minimise the risk of Noise-Induced Hearing Loss (NIHL). The guidance focuses on simple engineering and …
CIBSE have published (in 2016) a series of Guides in their “B” Series of which “B2” is of direct interest to those dealing in Industrial Ventilation/LEV. Section 2.2 sets out the criteria for the design of ventilation systems, covering the …
HSE Guide (looks like published Sept 2009) dealing with the foundations and “Technical Basis for the CoSHH Essentials: Easy Steps to Control Chemicals”. If you are familiar with Benchmarking (as per HSG258) then this document will provide you with so …
OXYL8 have recently produced a paper which considers whether there is a need in law for hood indicators/gauges. We know that HSE asks for these to be fitted but they also indicate in their LEV FAQ pages that there is …
This HSE Guide/Information sheet will help employers, the selfemployed and franchisees to comply with the Control of Substances Hazardous to Health Regulations 2002 (CoSHH), as amended, to control exposure to Isocyanates and protect workers’ health. This sheet describes good practice …
