explosive atmosphere

a mixture with air under atmospheric conditions of flammable substances in the form of gas, vapour or mist, in such proportions that it can be exploded by excessive temperature, arcs or sparks (the danger is a real one). In some contexts, a distinction has to be made between explosive and potentially explosive atmospheres, an atmosphere which could be explosive (the danger is a potential one).

Good to know

Kui on tarvis eristada 'explosive atmosphere' ja 'potentially explosive atmosphere', siis võiks esimese vasteks kasutada nt "reaalselt plahvatusohtlik keskkond"; kui mõlemad terminid ei esine koos, siis on tihti mõlemad tõlgitud "plahvatusohtlik keskkond". Vrd kirje 'potentially explosive atmosphere'. {30.05.2000}

plahvatusohtlik keskkond

Usage examples

Seade kasutamiseks plahvatusohtlikus keskkonnas ja mürgiste kemikaalide käitlemiseks.
Elektridetonaatorite jagunemine kasutamiskeskkonna järgi: 1) elektridetonaatorid, mida võib kasutada plahvatusohtlikus keskkonnas (gaas ja tolm) peavad olema vaskjuhtmetega ja hülssidega, mis on kaetud plahvatustemperatuuri alandava seguga;

explosive atmosphere

Usage examples

PPE intended for use in explosive atmospheres must be so designed and manufactured that it cannot be the source of an electric, electrostatic or impact-induced arc or spark likely to cause an explosive mixture to ignite.

an atmosphere which could be explosive (the danger is a potential one). In some contexts, a distinction has to be made between explosive and potentially explosive atmospheres (cf. "explosive atmosphere")

potentially explosive atmosphere

Usage examples

Machinery must be designed and constructed to avoid any risk of explosion posed by the machinery itself or by gases, liquids, dust, vapours or other substances produced or used by the machinery. To that end the manufacturer must take steps to: - avoid a dangerous concentration of products, - prevent combustion of the potentially explosive atmosphere, - minimise any explosion which may occur so that it does not endanger the surroundings.
