This is a glossary of basic LEV terms: ACoP – Approved code of practice. This carries greater legal weight in Great Britain courts than guidance. Aerodynamic diameter – The diameter of a unit-density sphere that has the same settling velocity in air as …
LEVCentral Expert Commentary Rotary valves are often overlooked because of their apparent simplicity. Yet they are among the most critical components in many pneumatic conveying, dust collection and bulk solids handling systems. A poorly selected rotary valve can restrict product …
LEVCentral Expert Commentary Construction dust is one of the largest causes of occupational ill health in the UK. Every day, thousands of workers are exposed to dust generated during cutting, drilling, grinding, chasing, sanding and demolition activities. While these dusts …
Understanding Buoyant Plumes from Hot Processes LEVCentral Expert Commentary Hot industrial processes create a particular challenge for ventilation engineers. Welding, furnace work, molten metal operations, heated tanks and other exothermic processes generate buoyant plumes that rise rapidly from the …
LEVCentral Expert Commentary One of the most common misconceptions surrounding combustible dusts is the assumption that if a material is not obviously dangerous, it cannot present an explosion risk. In reality, many everyday materials including food powders, wood dusts, pharmaceuticals, …
LEVCentral Expert Commentary Some of the most effective health and safety training resources are also the simplest. HSE’s Wood Dust Exposure (Sweeping!) video—also known as “Clean Your Act Up”—is an excellent example. Using a dust lamp (Tyndall lighting), the video …
Essential HSE Guidance on Preventing and Mitigating Combustible Dust Explosions LEVCentral Expert Commentary Many everyday materials become potentially explosive when converted into fine dust and dispersed in air. Flour, sugar, grain, wood dust, coal dust, plastics, pharmaceuticals and many …
Task-Specific Guidance for Controlling Exposure in Printing Processes LEVCentral Expert Commentary The printing industry uses a wide range of inks, coatings, solvents, cleaning agents, adhesives and curing systems. These materials can generate hazardous vapours, mists, aerosols and skin contact …
LEVCentral Expert Commentary Electrostatic Precipitators (ESPs) are among the most effective particulate collection technologies used in industry. Capable of achieving collection efficiencies approaching 99% in many applications, they are widely employed in power generation, cement manufacture, metal processing, waste incineration …
Task-Specific Guidance for the Safe Use of Dichloromethane in Paint Stripping and Adhesive Applications LEVCentral Expert Commentary Dichloromethane (DCM), also known as methylene chloride, is one of the most hazardous solvents still encountered in certain industrial applications. Although extremely …
