Regulations and Standards for Equipment Operating in Explosive Atmospheres

Reprinted from "Built to Blast: Industrial Internet of Things Infrastructure for Hazardous Environmentsby Aruba Networks.  Full text white paper can be downloaded here.

A potentially explosive atmosphere exists when air gas, vapor, mist, or dust – alone or in combination – are present under circumstances in which it or they can ignite under specified operating conditions. Places with potentially explosive atmospheres are called “hazardous” or “classified” areas or locations.

Multiple local and international regulations are in place to mitigate the risk posted by operating networks and IoT devices in potentially explosive atmospheres. Increasingly these regulations are becoming harmonized under a framework developed by the International Electrotechnical Commission (IEC) and European and US standards.

ATEX Directives

ATEX, derived from the French phrase “Atmosphères Explosibles,” is a European regulatory framework for the manufacture, installation, and use of equipment in explosive atmospheres. It consists of two European Union (EU) directives:

  • 1999/92/EC which defines the minimum safety requirements for workers in hazardous areas; and
  • 2014/34/EU which covers equipment and protective systems intended for use in potentially explosive atmospheres.

These two directives define the essential health and safety requirements, as well as the conformity assessment procedures, that need to be applied before products can be used in the EU market.

IEC Ex System (IECEx)

IECEx is a voluntary certification program that validates compliance with IEC standards related to safety in explosive atmospheres. Details about IECEx, its coverage areas, and conformity mark system can be found at www.iecex.com.

European Committee for Electrotechnical Standardization (CENELEC)

CENELEC was formed to facilitate a consensus-building process between European and international electrical standards activities. In 1996 CENELEC and the IEC formalized a framework of cooperation through an agreement on common standards planning and parallel voting that is known as the Dresden Agreement. As a result of this initiative both CENELEC and IEC have similar standards for explosive environments.

National Electrical Code (NEC)

NEC defines the standards for the safe installation of electrical wiring and equipment in the United States, and its standards are coordinated with those of the National Fire Protection Association (NFPA). NFPA 70 Articles 500 thru 510 address safe practices for the location and operation of electrical equipment in hazardous locations installations.
Additional national standards relating to hazardous environments may be in effect in different countries, however, there has been a concerted effort in recent years to harmonize local standards with the standards referenced above.

IIoT (Industrial Internet of Things) Wireless Networking Considerations in Hazardous Environments

Industrial Internet of Things Wireless Networking
BUILT TO BLAST
Industrial Internet of Things Infrastructure for
Hazardous Environments
Industry groups and standards bodies have collaborated to address these issues by classifying explosive materials and defining standards under which networking equipment and Internet of Things (IoT) devices can be safely operated in their presence. The work has been conducted by different organizations, in different regions, and it can be challenging to understand which standards are applicable under different scenarios.

This white paper examines the different categories of explosive risks, which standards to apply under different scenarios, how network infrastructure can be deployed in explosive environments, and how sensor systems can be integrated with this infrastructure. The goal is to enable end customers and resellers to select the network infrastructure, enclosures, and associated systems that are best suited to each scenario.

Safely Locate Your Aruba AP 318 in Hazardous Areas with this New Enclosure

Wi-Fi coverage is increasingly required in all areas of the modern industrial manufacturing plant. Adding wireless access points in non-hazardous areas, in an environmentally protected structure, is relatively simple. Many times the access point's own enclosure is all the protection required for that service.

On the other hand, creating a reliable wireless data transmission network in locations with dangerous concentrations of flammable gases or ignitable dust present unique network challenges. Industries such as off-shore drilling, petrochemical refining and mining require wireless networking components rated for use in hazardous areas.

Hardened access points, such as the Aruba Networks AP 318, are built for rugged environments. The AP 318 is capable of operating from -40 F. up to +140 F., and the unit's enclosure provides water and dust protection. However, if the access point is being located in a hazardous area (an area where flammable vapor, gas or dust exist) it will have to be mounted inside a hazardous area access point enclosure.

The Analynk AE902 Hazardous Area Access Point Enclosure provides the approvals and features required for hazardous area applications. Designed specifically to house the Aruba AP 318 access point, the AE902 enclosure allows facilitates the deployment of wireless networks in Class I, Division 2, groups A, B, C, & D areas, and combines protection for harsh, wet and corrosive environments. It includes a NEMA 4X rating to withstand driving rain, blowing sand, dust, splashing, and an occasional hose down. Finally, the AE902 comes complete with a PoE (Power over Ethernet) injector and AC to DC power supply for simplified wiring.
