- Class I and Class II Controls – Gas Detection |
| A
continuous gas detection system shall be provided to detect the presence of a
gas at or below the permissible exposure limit in occupiable areas and at or below
1/2 IDLH (or 0.05 LC50 if no established IDLH) in unoccupiable areas.
The detection system shall initiate a local alarm and transmit a signal to a continually
staffed remote location (to provide an immediate response to an alarm). The alarm
shall be both visual and audible and shall be designed to provide warning both
inside and outside of the interior storage, use or handling area. The audible
alarm shall be distinct from all other on-site alarms. |
