Ultimate Guide to Vacuum System Maintenance Safety

Vacuum quality is sub-divided into ranges according to the technology required to achieve or measure it. Low Vacuum (also called “rough vacuum”), can be achieved by basic equipment such as a vacuum cleaner. Medium Vacuum is typically achieved by a single pump, but the pressure is too low to measure with a mechanical manometer.Get price

Prevention of dust explosions in the food industry

IntroductionDust Explosion HazardsPrecautions Against Dust Explosion HazardsSolids ProcessingSources of Further Information1.1 Explosions and fires within the food industry from combustible materials are a known hazard and they can have devastating and irreversible effects. This information sheet concentrates solely on the fire and explosion hazards encountered in the food industries from dusty and powdered substances. 1.2 General guidance on the prevention of fires and explosions from dusts is contained in HSE publication HSG103 'Safe handling of combustible dusts – precautions against explosions'. This note should be read in conjunction with that guidance. 1.3 There are other hazards that may also need to be controlled, such as those from flammable gas (fuels for ovens), flammable liquids and vapours (spirit based flavourings and cooking/coating oils). The risks from these hazards will need to be assessed by a competent person and appropriate measures applied if you are to comply with the law. The control of these risks is beyond the scope of this document. 1.4 Legislation introduced in 2002 - the Dan...Get price
