Design of Combustible and Toxic Gas Detection Systems
standard by Process Industry Practices, 12/01/2004
This Practice provides the criteria for engineers for the design of detection and monitoring systems that are installed in plant areas to alert personnel of the presence of combustible or toxic gas. The systems addressed in these criteria are for permanently installed, fixed combustible and toxic gas monitors.

Fixed Gas Detection Design Criteria
standard by Process Industry Practices, 01/01/2016
This Practice addresses combustible, oxygen, and toxic gas detectors permanently installed for ambient air monitoring (e.g., leak detection, oxygen depletion). The technologies included are catalytic bead, infrared, and electrochemical. This Practice does not cover portable gas monitoring equipment, analyzers, or sampling systems.
The systems used to perform data acquisition, alarming, and control action are not covered by this Practice because the solutions are diverse and can include stand-alone to advanced multisystem configurations.
