Toxic Gas And Voc Measurements (Figure 3-7); Warning - MSA Sirius Operating Manual

• Alarms can be set to trigger on two different conditions:
• Deficiency/too little oxygen (setpoints less than 20.8)
• Enriched/too much oxygen (setpoints greater than 20.8).
• When the alarm setpoint is reached for either of the above:
• Alarm sounds
• Alarm lights flash
• % O 2 flag next to the concentration flashes.
If the Oxygen alarm condition is reached while using the
instrument as a personal or area monitor, leave the area imme-
diately; the ambient condition has reached a preset alarm
level. If using the instrument as an inspection device, do not
enter the area without proper protection. Failure to follow this
warning will cause exposure to a hazardous environment
which can result in serious personal injury or death.
