Hazardous Gas Detection
Hazardous gas and flame monitoring are an integral part of programs
designed to maintain personnel safety and protect the plant and the
environment. There are three major categories of hazardous gases:
Combustible gases - posing a risk to personnel and facilities through
Toxic gases -creating both immediate and long term risk to personnel
Oxygen displacing gases - depleting workers' oxygen supply in
The gas and flame monitoring system required for a specific application
depends upon the scope of the hazardous gas risk. Important factors in
determination of level of protection needed include:
Identify the hazards
Assess risk of hazardous event
Comply with laws and insurance requirements
Consider liability and financial risks
Develop and implement a strategy of comprehensive event
response and prudent risk management
For applications where the risk is minor, a simple gas monitor, such as the
Model 20X or 200X, interfacing with a panel that sounds an alarm when
the concentration reaches the setpoint may meet the need. Applications
involving a higher risk generally require continuous output of gas
concentration from gas sensor modules such as the analog gas sensor
modules, to a display, printer or other indicating/control device. Sierra
Monitor has the experience and the products to meet any level of gas
monitoring necessary to meet the user's safety requirements.
For more complex or larger applications, a comprehensive gas risk management system including
smart sensors provide a range of features necessary to meet this higher level of risk. The Sentry
system and the IT series sensors provide the user the intelligent data handling, ease of installation,
comprehensive alarm logic, low operating costs and reliable proven performance demanded by
today's instrumentation and safety professionals.
