Energy isolation is an example of mobile equipment maintenance

purpose

Prevent accidental startup or electric shock

Prevent mechanical crush injury, crush injury

To prevent burns

Fire and explosion prevention

Be familiar with equipment hydraulic diagram and know the isolation point of stored energy

How to isolate? To prevent accidental

Shock proof (electrical)

Turn off the engine and collect the keys

Pressure proof (mechanical)

Secure the wheels with triangular wood, and place warning signs before and after the car.

If the wheel is jacked up with a jack, it should be firmly supported. When releasing the jack, observe whether there are people or obstacles around.

The bucket or carriage is placed on the ground or where it is firmly supported.

When checking the hydraulic tubing, do not proceed until the tilting trunk or bucket is firmly supported (e.g., securing pins).

Scald prevention (thermal energy)

When the engine is running, it is not allowed to repair. If you want to repair after flaring up, you should prevent the body from being scalded by the exhaust pipe.

When the temperature of the engine is high, it is not allowed to open the cover of the water tank to prevent the scalding.

Explosion proof (chemistry)

Oil drums or mailboxes should be thoroughly cleaned before welding repair, battery room should be free of Mars, in case of explosion.

Fire prevention

Open flames are not allowed on gasoline cars

purpose

Prevent accidental startup or electric shock

Prevent mechanical squeeze, pressure

Other damage

All energy sources must be Lockout tagout before the maintenance operation is implemented

All energy sources must be Lockout tagout before clearing or plugging operations
