TASK 1
During the maintenance of the electrical machine, there are two machines which have both
mechanical and electrical hazard during the planned maintenance of the electrical. For the first
machine which is a conveyor belt employed in the transportation of products. This conveyor also
contains elevator which is driven at a voltage of 230V DC/AC. The below are some of the
electrical and mechanical hazards while a planned maintenance is undertaken (Bird, 2013).
Mechanical hazard
1. When the cleaners of the conveyor belts are doing the cleaning. The conveyor belt shall
not be cleaned manually while the belt is in operation ( fall of a person into the belt)
2. When mechanics are busy operating the conveyor the moving machine shall be guarded
to help protect an individual from contacting the sprocket, gears, flywheel, coupling
shafts and fan blades of the rotating parts.
Electrical Hazard
1. When the electrical technician are maintaining the conveyors, they should have to ensure
that the electrically powered conveyor belt should be de-energized or switched off before
any mechanical work is done on it.
2. If there is maintenance done in the machines for both the electrical and mechanical
repair suitable warning notice must be posted at the power switches and power switches
will be locked
The next set of the machine which was involved in the planned maintenance is a mixing tank
agitator driven by a 400v induction motor controlled by a variable speed drive (Bahalt, 2012).
