Fixed Gas Detection
The Fixed Gas Detection (FGD) Determination Process for Compressed Gases, Cryogenic Liquids, Other has been developed as a decision-making tool to assist in understanding when FGD is required versus when it is an operational decision.
The ²ÝÝ®ÎÛÊÓƵµ¼º½ , should also be referenced as it outlines controls that when implemented may mitigate the risk to an acceptable level and negate the need for FGD.
This Standard outlines what fixed gas detection (FGD) system components are required, and the performance requirements for the installation, maintenance, and operation of FGD systems at ²ÝÝ®ÎÛÊÓƵµ¼º½. FGD may be installed to accommodate use of compressed gases, cryogenic liquids, or specialized equipment/operations.
This Standard applies once it has been determined that a fixed gas detection (FGD) system will be installed. Reference to the ²ÝÝ®ÎÛÊÓƵµ¼º½ document can be made to assist in making this decision, and in understanding when FGD is required versus when it is an operational decision.
The ²ÝÝ®ÎÛÊÓƵµ¼º½ document, should also be referenced as it outlines controls that when implemented may mitigate the risk to an acceptable level and negate the need for FGD.
