  • Ultimate Guide to Vacuum System Maintenance Safety

    There are a number of physical hazards associated with vacuum systems, these include: the introduction of high-pressure gas into the system; the compression of gas by the system; the sudden increase in temperature of volatile gas(es) in the system; a phase change leading to the deposition of solid products; a reaction inside the vacuum system; and a blocked exhaust. Vacuum system safety is enhanced by knowing the system, the products employed and following strict procedures.
