From traditional industrial environments to today\u2019s increasingly complex hazardous processes, the risk of explosion and\/or fire remains a critical concern. However, basic process controls typically do not warn of conditions outside normal system limits. Since industry vapours and gases (hydrocarbons) burn with very high flame temperatures, an external fire detection system that can rapidly sound an alarm in the event of a fire is essential to protect human lives and valuable equipment.<\/p>\n

As a safety professional, you want to purchase flame detectors that best meet your facility\u2019s particular needs. Here are a few things to consider when researching a flame and gas detection system.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

The most popular systems use optical methods to detect flames; that is, they detect the absorption of light at specific wavelengths. Two common optical flame detector types are (1) combination ultraviolet\/infrared (UV\/IR) and (2) multi-spectrum infrared (MSIR). Unlike simple UV or IR detectors, UV\/IR and MSIR devices are sensitive to more than one band on the energy spectrum and therefore are less likely to produce a false alarm. Both technologies function well either indoors or outdoors and provide a reasonably fast response time.<\/p>\n

Should you choose UV\/IR or MSIR detectors? That depends on several factors.<\/strong><\/p>\n
