Installing the right flame and gas detection fire protection
system is essential for workplaces that contain toxic or combustible gas as a
part of their industrial process.
A flame detector senses fire and responds as programmed.
Different systems offer different levels of fire detection. A flame detector may
activate an alarm, shut down a fuel line, or trigger the area’s fire
suppression system. If you opt for a flame detection system in an industrial
furnace, it will monitor to ensure that the furnace is properly lit.
The ultraviolet/infrared flame detector is a popular choice
for many industrial plants. It activates when two different spectrums of
radiation are recognized. It’s important to choose a well-made sensor for flame
detection, preferably one that is explosion-proof. Consult with an expert in fire
protection to ensure that you’re investing in the right fire protection for
detector senses gas, able to flag gas leaks and shut down systems to help
prevent disaster. It can also alert nearby workers so the area can be cleared.
Gas detectors usually check for combustibles, such as methane, propane, or gas;
oxygen; or toxic gases, like carbon monoxide, hydrogen sulfide, and other toxic
There are many types of gas detectors, including ultrasonic
sensors, semiconductor sensors, and others. Some can detect multiple gases
while others are calibrated for just one gas.
Infrared combustible sensors work well when there is little
oxygen. This sensor reflects light off of a mirror and then measures the amount
of light absorbed during the refraction. It isn’t able to detect hydrogen but
works well when calibrated for methane or ethane.
Electrochemical toxic gas sensors are programmed for a
specific chemical so it’s important to ensure that the right one is on site.
There are about 30 different types of gases that can be detected. They provide
about one year of gas detection for most toxic gases and tend to be very
Choosing a Flame and
Gas Detection Fire Protection System
When you’re choosing a flame and gas detection system for
your workplace, it’s important to consider many aspects of the possible
sensors. Be sure to research the false alarm immunity. This is especially true
if your plant contains many hot objects so the flame detector doesn’t confuse
an actual fire with sunlight or welding.
The detection range is also important. You need full
coverage, including in areas you may not expect to be impacted. The greater the
range and the shorter the detection time, the more time you have to clear the
area and prevent further disaster.
Look for units that can perform self-diagnostics so they can
run regular checks. Such detectors should be able to detect that the sensing
paths are clear, the detector is working, and that all electric circuits within
the unit are functioning.
Any industrial plant, warehouse, or hangar that deals with
combustible or toxic gases needs to have a well-maintained fire protection
system. A major part of any fire protection system is the flame and gas
detection equipment, which can help save lives and prevent disaster.
