Electrical Hazards Flashcards
Sources of electrical
from small batteries in electronic systems, through to power distribution systems at Extra Low Voltage, High Voltage, static electricity and lighting
Danger
risk of electrical burns, electrical
shock and even electrocution.
Electric shocks
shock is increased if a person is in good
electrical contact with earth.
Where are electric shocks an increased risk
in damp/wet conditions
I’m conducting location (metal tank)
When do most accidents occur
A. That is thought to be dead, but which is still live
b. That is known to be live, but those involved do not have adequate training.
experience, or there is a lack of supervision
C. When using equipment for the task that is not appropriate and knowingly taking
unnecessary risks (e.g. not following a safe system of work).
Fires may be started
- Overheating equipment due to overloading
- failure of electrical equipment
- leak faulty insulation
- Overheating of materials close to electrical equipment
- ignition of materials caused by arcing or sparking
Electrical safety personal responsibility
- Perform pre-use checks
- any suspected faults reported to supervisor
Key tips for portable electrical equipment
- The nearest suitable socket
- avoid over stretching = so it’s easy to disconnect
Sockets
- Should not be overloaded
- scheduled inspection
Electrical safety devices
- personel should not modify or bypass devices
What should portable equipment outdoors have
Residual current device protected socket
Inspections = two types
- User visual checks = pre use examination
- formal visual checks
Carried out at specific times and intervals
