Safe gas monitoring with Bieler+Lang

Hazardous gases in the laboratory

Many gases pose chemical hazards. For example, chlorine (Cl₂) and nitrogen oxides (NOₓ) are highly corrosive and toxic. To ensure compliance with COSHH guidelines, the occupational exposure limits should be checked in accordance with HSE document EH40 or the safety data sheets (SDS). Even supposedly harmless gases such as nitrogen (N₂) or argon (Ar) can cause asphyxiation in poorly ventilated areas.

There is also a high risk of explosion and fire with certain gases. Gases such as hydrogen (H₂) or methane (CH₄) are stored in pressurized containers and can cause dangerous explosions if handled improperly. Even small sparks from electrical appliances or hot surfaces can cause fires. Oxygen leaks significantly increase the risk of fire as they drastically increase the local oxygen concentration and therefore flammability.

Another example of hazardous gases are carbon monoxide (CO) and nitrous oxide (N₂O), which are toxic and have strict limit values for short-term (STEL) and long-term exposure (LTEL). These limit values can be found in HSE document EH40 or on the respective SDSs.

Because of these risks, it is crucial to detect gas leaks at an early stage. Modern gas detectors provide both audible and visual alarms to alert different user groups, including hearing impaired people. Networked systems (known as addressable systems) allow multiple detectors and alarms to be installed on a common wiring. This not only reduces installation costs, but also provides continuous monitoring and fault reporting.

One example is the monitoring of oxygen and carbon dioxide (CO₂). CO₂ has been classified as a harmful substance since 2002 and has clear limit values for workplace exposure. A dedicated CO₂ sensor is required as oxygen monitors do not cover CO₂ risks. Compliance with these standards is mandatory in accordance with BS EN 60079-29-2.

Advantages of Bieler+Lang gas detection technologies

Bieler+Lang has been offering innovative gas detection solutions for over 50 years. Thanks to our partners in the smg (safe monitopring group), we offer innovative digital gas detection systems in addition to our own numerous devices for gas detection systems. Our 2-wire technology enables simple installation with minimal cabling. Detectors can interact with additional devices such as visual indicators, call points or relays.

Particularly noteworthy are our long-life oxygen sensors, which last more than 5 years – significantly longer than the industry average of 2 years. This reduces maintenance costs and minimizes false alarms.

Our addressable systems offer numerous advantages:

• Flexibility: Easy integration of additional detectors.
• Safety: Pre-alarms and main alarms for early warning.
• Connectivity: Remote monitoring and data logging via the Internet.
