A process of evaluating the probability and consequences of injury or illness arising from exposure to an identified hazard, and determining the appropriate measures for risk control is known as
Risk Control.
Risk Evaluation.
Risk Assessment.
Risk Management
An electric shock is caused by
the loss of fluid in the human body.
the loss of blood in the human body.
a voltage passing through the human body.
an electric current passing through the human body.
When a person received an electric shock and he felt ventricular fibrillation and death, he is likely received an electric shock current of
5mA – 10 mA
10mA – 15mA
20mA – 30 mA
50mA and above
Electrical accident will cause electrical injury, which of the followings is not the result from electrical accident?
Burn
Bleeding
Electric shock
Muscular contraction
The best way to reduce the risk of electric shock when servicing electrical equipment is to
stand on metal mat.
use uninsulated tools.
ensure equipment is not earth.
isolate the equipment from the supply.
Before an electrical appliance is connected to the supply, we must first check the
power rating.
current rating.
voltage rating.
class of insulation.
When rescuing an electric shock victim who is still in contact with the live equipment, one must first ensure that the
supply is isolated.
victim is still conscious.
first aid box is available.
ambulance has been called.
The severity of an electric shock is determined by
The voltage.
The power supply.
The circuit resistance.
The amount of current flow.
One of the possible situations a person will receive a much lesser degree of electric shock is when he is
walking barefoot on a carpet.
in a bathroom after a shower.
sitting on a field and having his lunch.
leaning on a metallic lamp post waiting for his bus to arrive.
A textile worker was electrocuted when he touched a sewing machine frame while performing his maintenance duties. This form of electrical shock is known as
direct contact.
human contact.
indirect contact.
accidental contact.
When a flexible cord or cable is cut and a contact is made with a mains supply conductor and earth. Under electrical safety, this is known as
direct contact.
human contact.
indirect contact.
accidental contact.
In Risk Assessment, the severity of the hazard is classified into 3 categories namely, minor, moderate and
major
highest.
serious.
Maximum.
