Crowcon’s Gas-Pro PID protects workers from VOCs and H2S
07 May 2014
Photo-ionisation detection finds toxic compounds at very low concentrations
Crowcon’s new Gas-Pro PID portable gas detector, part of the popular Gas-Pro range, detects a wide range of volatile organic compounds (VOCs) found in many industrial applications.
VOCs are not only highly flammable, they also pose a significant toxic hazard at very low concentrations – well below the lower explosive limit (LEL) of the VOCs. H2S, also detected by PID, is likewise extremely toxic at very low concentrations.
Materials containing VOCs include acetone, benzene, paints, solvents, degreasers, plastics, resins and certain fuels – these occur in industries ranging from petrochemicals, oil refining, pulp and paper and aviation. H2S often occurs in oil refineries in a toxic mix with VOCs.
The Gas-Pro PID is specifically designed to detect and warn of these dangerous compounds well below the concentrations that they become toxic.
Key benefits include:
- Top-mount, easy-to-read display for quick decision making
- Ergonomic design
- Monitors up to five gases
- PID correction factor - set to target VOCs
- Broad range PID which detects hundreds of gases
- +ve Safety™; tri-colour status indication
- Water and dust resistant to IP65
There are many industries in which the use of PID sensors in multigas detectors could help protect the people that work there, examples of which include: Petrochemical and Chemical
There are many VOCs derived from the oil refining and petrochemical industries. These are essential to the production of a lot of important materials, such as dyes, plastics, detergents, solvents, paints, synthetic rubber and pharmaceuticals. Exposure to these compounds can occur during their transportation, storage or use, or as a result of a spillage or leak. Cargo Container Terminals
When containers are brought into port they could have been sealed for weeks or months. These containers carry goods made using glues, solvents and paints. When the containers are opened, anyone present can be hit by high concentrations. Hazardous Material (HazMat) teams
HazMat teams, like fire fighters or quick response teams, arrive at the scene of an incident with limited information about any hazard. It could be a truck that has overturned on the motorway or some sort of chemical spill at a production facility. Aviation
Aviation fuel poses a significant VOC hazard. Most of the work involved in inspecting and modifying airplane fuel tanks and their associated systems must be done from inside the tanks. Despite being emptied, the tank will contain jet fuel residue. Paints
Paint solvents are VOCs. They pose a VOC hazard not just to the paint industry but also the many industries that use significant quantities of paint in their operations.
