Ignition sources for dust fires and explosions can take many forms. When powders are heated, however, new subtle sources of ignition hazards are revealed: Those associated with the inherent thermal instability properties of the powder being heated or dried, and the nature of the drying process.

A fire that severely burned four workers at the ExxonMobil refinery in Baton Rouge, La., occurred when operators inadvertently removed bolts that secured a piece of pressure-containing equipment to a plug valve.

Screw-clamp terminal blocks include pluggable fuse and knife disconnect terminal blocks for potentially explosive areas (Class I, Zone 2).

Automation systems in chemical and petrochemical plants must meet high and constantly increasing demands.

The ELS-1150XP Series electro-optic liquid level sensors are designed and approved for flammable and explosive atmospheres.

IECEx ― the IEC system for certification to standards relating to equipment for use in explosive atmospheres ― has launched a mobile application to show international certificates.

The gas piping running into and through a facility is another overlooked hazard. Natural gas leaks can create an explosive and flammable atmosphere inside a building.
