Other horizontal surfaces like girders, beams and ledges should be bevelled to prevent settlement. All inspection doors, slide valves etc. Such modification to hazardous area zoning should zoneing be undertaken by a competent person.

Qtex flammability is established, zoning is determined following the grade of release: Equipment in use before July is allowed to be used indefinitely provided a risk assessment shows it is safe to do so. Because the level of hazard can vary from one location to another within zpnering same group classification, and not all locations ates the same variables, location groups are broken into zones based on how likely the threat or hazard is.

Window sills, door frames and projecting fittings should be made flush with the wall. Areas classified into zones 0, 1, 2 for gas-vapor-mist and 20, 21, 22 for dust must oznering protected from effective sources of ignition.

Vacuum cleaning is recommended for dust zonreing. Please help improve it or discuss these issues on the talk page.

Zone 1 — A place in which an explosive atmosphere consisting of a mixture with air of dangerous substances in the form of gas, vapour or mist is likely to occur in normal operation occasionally.

This page was last edited on 5 Novemberat Zone 20 — A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is present continuously, or for long periods or frequently. Zone 20 Continuous release inside a dust containment enclosure gives rise to Zone 20 – a place in which an explosive atmosphere, in the form of a cloud of combustible dust in air, is present continuously, or for long periods or frequently for short periods.
