Fixed benzene detector

11 May 2022

A CLASSIFIED carcinogenic, benzene is present in the production of asphalt, and managing exposure and minimising risk is critical for worker safety. ION Science has developed what is reported to be the only fixed detector on the market to specifically detect benzene, reducing the risk of exposure to workers, the public, and the environment.

Asphalt makes up a great deal of the built environment – roads, pavements, and buildings all use asphalt in some form when it comes to construction. As such a prominent building material, the production of asphalt (also known as bitumen) is a global business. Benzene is present throughout the manufacturing process of asphalt, as it is derived from crude oil, a product with naturally occurring benzene.

High numbers of personnel are involved in the manufacture and handling of asphalt all over the world, and protecting workers against benzene exposure risks is imperative for businesses. While some recommendations and laws exist, such as DEFRA Process Guidance Note 6/42 (13), which sets out annual extractive testing for bitumen related processing. OSHA does not currently have any legal requirements around asphalt fumes and preventative measures, beyond general respiratory and PPE safety. Laws exist around general emissions, VOCs, and carcinogens associated with asphalt production, however there is very little currently in place specific to benzene exposure.

With schemes such as the Road Improvement Scheme 2 (RIS2) in the UK, and Norway’s ambitious Route E39 coastal highway scheme (including an underwater floating tunnel), asphalt will continue to be a critical ingredient of developing infrastructure. Businesses are looking to get ahead of the law changes now by using a ‘safety first’ approach, and bringing in additional or updated benzene monitoring systems to factories and production sites.

Even at low levels, benzene exposure can result in headaches, dizziness, breathing difficulties, and eye, skin, and respiratory irritation. Long term exposure, even as little as five years, can result in more serious conditions, including blood disorders, cancers, and pregnancy risks. Regardless of whether there are legal requirements in place, businesses must protect their staff appropriately against benzene exposure.

The Titan is a specific fixed gas detector designed only for the monitoring of benzene. The company says this makes it the perfect choice for use in asphalt manufacturing plants, where benzene is likely to be the most prominent VOC (volatile organic compound) that requires management and monitoring.

As a fixed unit, the Titan can be installed at regular distances around sites, and with its ‘plug and play’ installation approach, the Titan can be left monitoring without the need for intervention. Two alarm systems can be set at the user’s convenience, and another two are pre-set relays for immediate warnings, so no exposure incident is ever missed.

The Titan offers continuous real-time data feedback of VOC concentrations in the air, taking samples every minute to an accuracy of 0.1ppm or +10%, whichever is greater. Using ION Science’s industry leading PID technology, the Titan is equipped with a 10.6 eV lamp that comes with a minimum one-year guarantee for performance. Servicing is only required every 6-12 months for the entire unit, making it an ideal choice for larger plants who need multiple units for wider-range monitoring.

Any manufacturing plant that handles asphalt production should look to install a Titan unit as part of efforts to protect workers from exposure.
