One of the areas where IoT can offer substantial benefits is in ATEX or hazardous areas, where traditional electronic devices pose safety risks due to the presence of explosive atmospheres. This article explores the application, benefits, and challenges of using IoT in ATEX and hazardous areas, focusing on safety, regulatory compliance, and technological advancements.

Understanding ATEX and Hazardous Areas

What is ATEX?

ATEX (ATmosphères EXplosibles) refers to two European Union directives that outline the minimum safety requirements for workplaces and equipment used in explosive atmospheres. The directives are:

• ATEX 2014/34/EU: Equipment and protective systems intended for use in potentially explosive atmospheres.
• ATEX 1999/92/EC: Minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres.

Hazardous Areas

Hazardous areas are environments where there is a risk of fire or explosion due to the presence of flammable gases, vapours, dust, or fibres. These areas are classified based on the frequency and duration of the presence of explosive substances:

• Zone 0: Explosive atmosphere is present continuously or for long periods.
• Zone 1: Explosive atmosphere is likely to occur in normal operation.
• Zone 2: Explosive atmosphere is not likely to occur in normal operation but may occur for short periods.

The Role of IoT in Hazardous Areas

Enhancing Safety

Safety is paramount in hazardous areas, and IoT can significantly enhance it by enabling real-time monitoring and data analysis. IoT devices can continuously monitor environmental conditions such as temperature, humidity, gas concentration, pressure and even asset tracking. By integrating these devices into a centralized system, it is possible to detect anomalies and potential hazards early, triggering automatic safety responses such as alarms or equipment shutdowns. It is also easier to increase safety by knowing exactly where valuable or dangerous assets are at all times.  

Predictive Maintenance

IoT enables predictive maintenance, which is particularly beneficial in hazardous environments. Traditional maintenance schedules are often based on fixed intervals, which may not accurately reflect the actual condition of the equipment. IoT devices can monitor the health and performance of machinery in real-time, allowing maintenance to be performed based on actual needs. This approach reduces the risk of unexpected failures and minimizes the time personnel spend in hazardous areas.

Asset Tracking and Management
