What is explosion-proof and intrinsically safe ?
Intrinsically safe and explosion-proof equipment limits heat and electrical energy to prevent the possibility of ignition. This may mean limiting the generation and build-up of heat to prevent the ignition temperature of a hazardous substance from being reached. In the case of electrical energy, this means preventing the possibility of sparking by keeping the voltage and current low. Preventing malfunctioning of electrical process equipment.
(Electrical equipment must sometimes be installed in hazardous locations – areas containing flammable gases, combustible gases, dust or fibres)
How are hazardous locations classified?
The North American zoning system is based on the National Electrical Code and has the following classifications.
Rating represents the general nature of the hazardous substance in the area.
Zoning indicates the degree of hazard present in the area.
Groups represent the types of hazardous substances present in the area.
In determining its classification, each room, section or area should be considered individually.
Hazardous Location Classes
Class I: Flammable gases, vapours from flammable liquids and vapours from combustible liquids.
Class II: Combustible dusts
Class III: Combustible fibres or splashes
Classification of hazardous locations
Class 1: Gases or vapours present or likely to be present at any time in concentrations sufficient to present an explosion hazard under normal operating conditions.
Division 2 Gases or vapours are not normally present and are only present in the event of a leak from some type of containment or pipework, again in potentially hazardous concentrations.
Hazardous Location Groups for Class I, Zones 1 and 2
Group A contains acetylene atmosphere.
Group B Atmospheres containing flammable gases (e.g. hydrogen) or fuels/gases containing more than 30% hydrogen by volume or gases with an equivalent hazard to hydrogen.
Group C atmosphere containing ether vapour, ethylene or cyclopropane.
Group D atmosphere containing gasoline, hexane, naphtha, benzene, butane, propane, alcohol, acetone, benzene, lacquer solvent vapour or natural gas (methane).
Class II, Hazardous Location Group for Zones 1 and 2
Group E Atmospheres containing combustible metal dusts, including aluminium, titanium, zinc and other metal dusts.
Group F Atmospheres containing carbonaceous dusts.
Group G Atmospheres containing combustible dusts not belonging to Groups E and F.
Zone System In Europe
The European zone system is based on the NEC, which follows the international zone classification developed by the International Electrotechnical Commission (IEC). The zone system defines hazardous locations by
Zones represent the general nature of the hazardous material and its likelihood of being present in combustible concentrations.
The group represents the type of hazard and the location of the surrounding atmosphere.
Hazardous Areas | Gases and Vapours
Zone 0: Combustible gases or vapours are present continuously or for extended periods of time.
Zone 1: Flammable gases or vapours that may be present under normal conditions.
Zone 2: Flammable gases or vapours that are unlikely to occur under normal conditions or within a short period of time.
Hazardous Area | Dust
Zone 20: Dust, fibres or flecks present continuously or for a long period of time.
Zone 21: Dust, fibres or droplets which may be present under normal conditions.
Zone 22: Dust, fibres or droplets that are unlikely to be present under normal conditions or for a short period of time.
Group I: Reserved for mines
Group II: Explosive gases (Zones 0-2)
Group IIA: Atmospheres containing propane, acetone, benzene and equivalent hazardous gases.
Group IIB: Atmospheres containing ethylene, propylene oxide, cyclopropane and equivalent dangerous gases
Group IIC: Atmospheres containing acetylene, hydrogen, carbon disulphide and equivalent dangerous gases.
Group III: Explosive dust (Zones 20-22)
Group IIIA: Atmospheres containing combustible flying materials.
Group IIIB: Atmospheres containing non-conductive dusts.
Group IIIC: Atmospheres containing conductive dusts.
Explosion-proof equipment in detail.
Explosion-proofing is the more common method of fixing the detector/sensor assembly of a gas detection system. It is designed for permanent installations where higher voltages/power are required.
The explosion-proof classification of a sensor/transmitter means that the design and construction of the housing can contain flash or explosion. These housings are usually made of cast aluminium or stainless steel. They have sufficient mass and strength to safely contain an explosion if a flammable gas or vapour penetrates the housing and the internal electronics or wiring causes an ignition.
The design must prevent any surface temperatures that may exceed the ignition temperature of the gas or vapour. If the sensing element is a high temperature device (such as a catalytic bead or “pellistor”) it may be protected by a flame arrestor to prevent the propagation of hot gases into the ambient atmosphere.
The intrinsically safe classification and design means that the electronic circuit and its wiring will not cause any sparks or arcs. It cannot store enough energy to ignite a flammable gas or vapour, nor can it generate a high enough surface temperature to cause ignition.
Intrinsically safe methods are also available for permanent installations where the detector/sensor is a relatively low power device. Almost all portable instruments are certified as intrinsically safe.
Permanent installations may include intrinsically safe barriers located outside the hazardous location. These barriers limit the amount of energy available to the equipment located in the hazardous area.

What Is An Explosive Hazardous Area?
Explosives hazardous areas occur where flammable liquids, vapors, gases or combustible dusts are likely to occur in quantities sufficient to cause a fire or explosion. Often, these atmospheres are created where gas, vapors, dusts and liquids are in contact with oxygen. Hazardous areas are divided into zones, where the probability of a hazardous atmosphere being present governs the explosion risk. Some areas are more hazardous than others, since it is more likely that there are gasses present. There are explosive gas atmospheres, explosive dust atmospheres, and the explosive atmospheres which may exist in coal mines.
