Hazardous Area Access Point Enclosures for Safety, Reliability, Convenience and Cost Savings

Hazardous Area Access Point Enclosures

Industrial wireless networks are a much-needed solution for hazardous areas where wired connections are impossible. Wireless networks are also an ideal choice for temporary or mobile applications.

Industrial Wireless Networking is a newer technology quickly becoming the standard for companies that need to transmit data wirelessly in hazardous areas. Industrial wireless networks are gaining traction in hazardous areas with distinct advantages over hard wiring. However, some disadvantages make it less desirable than hard wiring.

Industrial wireless networks are a cost-effective solution to provide reliable, secure, and fast internet access in hazardous areas. In recent years, the demand for industrial networks increased with the increasing popularity of IoT (Internet of Things). This industrial network segment is seeing a surge in demand as more instruments and supervisory control systems connect their devices to the Internet.

Wireless has been a solution to many challenges faced in industrial networking, from remote locations to temporary installations, with the convenience of mobility and reduced installation costs.  

An access point is a device that establishes a wireless local area network, often known as a WLAN. An access point uses Ethernet to connect to a wired router, switch, or hub and broadcasts a WiFi signal to a specific region of a building or plant. However, a significant challenge remains: how to prevent access points from causing ignition and protect the access point against harsh environmental conditions? 

Hazardous Access Point Enclosures
 are enclosures used to protect wireless access points in hazardous areas. They provide safety to the wireless network equipment and the people who work in the area.

Some of the hazards that might be present in a hazardous area include combustible gases, oxygen-rich atmospheres, and flammable dusts. These hazards can cause a fire or explosion if they come into contact with an open flame, spark, or heat source.

To ensure that access point devices can operate reliably in hazardous environments such as oil rigs or chemical plants, they need protection from combustible gases, dust particles, and corrosive chemicals.

The need for Hazardous Access Point Enclosures is increasing daily due to new wireless network technology and are a requirement for all access points operating in hazardous industrial areas. These enclosures protect the access points from dangerous areas and environments. They have various features to ensure the environment is protected and secure for the personnel working in the area.

Some of these features include:

  • Compliance with international standards
  • Resistance to extreme temperatures
  • Permits installation in any location within a hazardous area
  • Protection against dust and water ingress

Industrial wireless networks have a lot of benefits over hard wiring. The lack of wires makes installing and moving around in hazardous areas easy. In addition, you can eliminate the cost and hassle of having to replace or repair wires if they break or get cut. Access points are critical components of industrial networks, and Hazardous Area Enclosures are an essential safety measure for access point manufacturers when applying their products in these settings.

An Excellent White Paper for Understanding Wireless Networking in Hazardous Areas

Wireless in Hazardous Areas

A potentially explosive atmosphere exists when a gas, vapor, mist, or dust, alone or in combination, occurs in situations where it may ignite under specific conditions. A "hazardous" or "classified" area are places with highly combustible atmospheres that are potentially explosive.

Local and international regulations exist to minimize the risk posed in explosive atmospheres by the energy contained in and required by operating networks and IoT products. A gradual harmonization of these regulations continues to be structured and defined by the IEC and European and US standards.

Industry associations and standards bodies continue to work together to resolve classifying explosive materials and establish standards for the safe operation of networking equipment and IIoT (Industrial Things Internet) products in hazardous areas. Because different organizations perform the work in other areas, understanding which criteria are applicable under different conditions can be difficult.

Aruba Networks has been at the forefront of wireless networking in industrial environments. Their white paper entitled "BUILT TO BLAST: Industrial Internet of Things Hazardous Environment Infrastructure" discusses the various types of dangers, criteria, and conditions that need to be considered before deploying wireless network infrastructure in explosive environments. You can download the white paper here.

The growth of connected industrial IoT devices moves in unison with initiatives to improve operations, maximize efficiency, allow better inventory management, and enhance plant safety. Understanding the unique requirements of wireless networking and communications in hazardous areas is critical.

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

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.
