Dusttight equipment is defined in the national electrical code as so constructed that dust will not enter.

Class ii division 2 group g. Our dust ignition protected vacuum systems are osha nrtl certified for use in class ii, division 2, groups f &g hazardous locations (zone 22 for dust group iiic conductive dusts). Class ii, division 1, groups e, f, g: As you can see by the breakdown, groups a, b, c and d are for class i (gases) only.

Division system, class ii (dusts) type of : Groups e, f, and g are for dusts and flyings (class ii or iii). Division ii because flammable vapor would only leak from the tanks if there was an accident.

In this area the gas, vapor or liquids would only be present under abnormal conditions (most often leaks under abnormal conditions). The national electrical code, or nec, classifies hazardous areas into three different categories; These portable single phase electric models are ideal for general cleaning.

Nec class ii divisions 1, 2 groups e, f, g. E combustible metal dusts, f combustible carbonaceous dusts or g other combustible dusts. Division i because dust is present during normal operation.

Nec zone 1 groups iib, iia. How to apply the rules of article 502 when there’s risk of fire or explosion due to the presence of combustible dust. Groups a, b, c, and d are for gases (class i only).

Class ii combustible dusts are grouped into one of three (3) groups: Nec class ii division 2 groups f, g. The ip rating and explosionproof rating are different.

Source of ignition — a spark or high heat must be present. Class ii location groups are determined by: Class ii locations are divided into three groups e,f,g.

All ip67 rating equipments can not be used in classified area. Nec zone 1 groups iic, iib, iia. Class i, class ii, and class iii.

They are class i (gases & vapors), class ii (flammable dusts) & class iii (fibers), the focus of today’s blog is on class ii locations. Most common is air (o2). Nec class ii divisions 1, 2 groups f, g.

Class ii hazardous areas, groups e, f and g explained. Class ii division 2 groups f & g; For most equipment in class ii, division 2 locations, the national electrical code indicates that dusttight equipment can be used.

Division 1 groups e, f, g: Per the national electrical code (nec) there are (3) classifications for areas that are defined as hazardous. Nec zone 2 groups iib, iia.

Group (class i) group a atmospheres containing acetylene. Nec zone 1 group iia. Class i, division 2 or zone 2 classified locations an area where ignitable concentrations of flammable gases, vapors or liquids are not likely to exist under normal operating conditions.

Class i because of flammable vapor. [nec] group g refers to an area that contains combustible dusts that are not included in groups e and f, such as flour, grain, sugar, wood, starch, chemicals and plastics. Coal dusts class ii, group f:

To use equipment in or around these types of areas, caution has to be taken to not cause an explosion or fire. 1, groups e, f and g. 2, groups a, b, c and d:

The specific hazardous materials within each group and their automatic ignition temperatures can be found in article 500 of the national. Groups e, f and g are for classes ii and iii (dusts and fibers or flyings) only. Where ignitable dust or vapors may be present.

Class ii group f & g locations are atmospheres containing dust such as (f) carbon black, coal or coke dust, (g) flour, starch or grain dusts. Division ii locations in which hazardous concentrations are handled, processed, or used but are normally within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown. The presence of these three elements make up the sides of the ignition triangle.

Oxidizer — must be present in sufficient quantity in combination with the flammable substance to produce an explosive mixture. Grain dusts class ii, group g: Group d because propane is in the atmosphere.

Class ii because of combustible dust. For outdoor application in class ii, div.2 group g, you can very well use combination of nema 4 (very approximate equivalent to ip 66) & nema 9 ( for hazardous locations) enclosure. Class i flammable gases and vapors are grouped into one of four groups (groups a, b, c or d) based on their physical properties and the ease in which they can be ignited.

Ruwac recognizes the seriousness of the potential deadly hazard found in combustible dust, and offers a complete line of electric powered explosion proof vacuum systems for class ii, division 2 environments.
