National security supervision bureau issued 'aluminium magnesium products machining dust explosion-proof safety technical specifications'
recently, state the supervision and administration of production safety administration issued about & other; Aluminum magnesium products machining dust explosion-proof safety technical specification & throughout; The industry standard. This standard is mainly for aluminum magnesium products mechanical processing enterprises, build environment of dust explosion danger area ( Structure) Structures of the layout and structure, fire protection and fire control facilities and electrical explosion protection safety, dust removal system, mechanical processing equipment, operation safety, dust cleaning, security management and planning and requirements. This standard applies to aluminum magnesium products mechanical processing workshop, venues and equipment and facilities ( Aluminum magnesium powder production and processing enterprises not included), 。 File, according to the standard will be implemented on 1 March 2017. Standard requirements, the aluminum magnesium products mechanical processing enterprises should be dust explosion hazard identification and risk assessment, the production safety accidents, and in accordance with the GB 15577 dust explosion-proof safety measures as well as the standard requirements. Dust explosion danger area of building fire protection design should comply with the requirements of GB 50016, explosion-proof pressure workshop building design should conform to the requirements of GB/T 15605, at the same time, the factory building lightning protection design should comply with the requirements of GB 50057. Danger to the environment of the dust explosion area ventilation, heating and air conditioning system, should comply with the requirements of GB 50019, send, exhaust system, fire safety should comply with the requirements of GB 50016, focus, aluminum warms and ventilation pipeline before pipeline into dust explosion danger zone should be set fire damper, refrigeration and air conditioning system ( Hot) Device shall not be used in dust explosion danger area. Dust explosions produce danger zone shall not adopt any flame and high temperature environment and release of flammable gas produce dust explosion danger way of production and process, and shall not be set up and use produce explosion danger of air compressor, pressure vessel, cylinders, heating, steam system equipment and devices, etc. Dust explosion danger zone because of special need temporary arrangements for hot work, should stop to, including aluminum magnesium products mechanical processing, production operation, equipment maintenance and field cleaning work, hot work should obtain approval approval and dangerous operations according to the requirements of GB 15577 fire safety measures. Standard also provides, homework personnel should be tested and approved by the training of qualified, the party must mount guard. Dust explosion danger area operations personnel should wear anti-static equipment, dust mask, should check work post, 'before the dust hood or vacuuming ark without dust, dust removal equipment of ash hopper, dust collection containers ( Barrels a day). Have clear grey. Environment and dust explosion dangerous areas should be set up security warning signs. In terms of safety management, should ensure that dust removal system and dust explosion dangerous area electrical wiring, electrical equipment monitoring alarm device and control device in accordance with the explosion-proof safety requirements, and at least once every half a year to maintenance. Shall be cleared away before maintenance work areas, machinery processing equipment, dust removal system, and the surrounding area of dust, hot work should be fire safety measures according to the requirements of the file ( See the standard the original) 。 Should be done at the same time, the aluminum magnesium products mechanical processing production process hidden perils in production safety accidents, and establish the hidden perils in accident management files, eliminate the production safety accidents.
