Toxic Gas Monitoring Systems – Design & Integration One Approach ...

TGMS – Design & Integration Safety Goals
Flexibility:
• The ability to easily – and quickly – schedule periodic sensor maintenance,
sensor additions and sensor removals, without compromise to operational gas
safety monitoring or interruptions are very important.
• Scheduled periodic testing of the TGMS – similar to the facility Fire Alarm
System (FAS) are performed to eliminate the presence of any passive safety
system fault – to ensure TGMS availability.
• A TGMS in a research or manufacturing environment, requires the flexibility to
accommodate changes in target gas and the corresponding changes in alarm
settings, safety actions and alarm notification. Changes are typically required
“on-line” in the manufacturing environment.
• Management of Change (MOC) is critical to the integrity of the TGMS.
• Functional changes to the TGMS require “reacceptance testing” to verify
hardware/software changes are valid.
