Lab Hazards, Electrical and Fire Safety
What could go wrong in a computer lab, and what should we do about it?
- Identify common lab hazards
- State electrical safety rules
- Describe fire response steps in a lab
Overview
Computer labs are safer than workshops, but hazards still exist: overloaded sockets, trailing cables, spilt drinks, and electrical fires. A short checklist of habits keeps everyone safe.
Common Hazards
Trailing cables (trip), overloaded power strips (fire), drinks near equipment (short-circuit), damaged plugs, blocked exits.
Electrical Safety
One appliance per socket where possible. Never touch equipment with wet hands. Report damaged cables. Do not open computer cases.
Fire Response
Raise the alarm. Do NOT throw water on an electrical fire — use a CO2 or dry-powder extinguisher. Evacuate calmly to the assembly point.
