Occupational Health, Safety and Emergency Response
This domain tests whether you can audit safely and keep evidence intact through power cuts, fires, medical emergencies and long shifts.
Control room hazards
Prolonged sitting, glare, poor posture, eye strain, shift-work fatigue, noise, heat, trailing cables and overloaded sockets. Controls: an adjustable chair and desk, the top of the screen at or just below eye level and about an arm's length away, anti-glare treatment, moderate ambient light rather than a blacked-out room, task rotation, a short break roughly every 60–90 minutes, plus the 20-20-20 habit (every 20 minutes, look 20 feet away for 20 seconds).
Emergency response
RACE for fire: Rescue anyone in danger, Alarm, Contain by closing doors, Evacuate to the assembly point for roll call. PASS for extinguishers: Pull the pin, Aim at the base, Squeeze, Sweep. Indian emergency numbers: 112 all-in-one, 100 police, 101 fire, 108 ambulance. Know the assembly point, fire warden and evacuation route before your shift, not during one.
Protecting evidence during an emergency
Lock the control room if time allows, note the evacuation time, do not power down recorders unnecessarily, and rely on the UPS for short outages. Afterwards, record which cameras were offline and for how long, so no one later assumes 'no activity' from a blank period.
Worked example
A fire alarm sounds at 21:14. The operator logs it in the OB, evacuates, and returns at 21:52. Cameras 1–8 were offline from 21:30 to 22:05 after power was restored. The auditor documents the gap and its cause in the report.
Traps
Ignoring fatigue as a cause of missed events; no roll call; storing boxes in front of fire exits or extinguishers; assuming recorders survive long outages without UPS or generator backup.
