Current-
Direct Current (DC) in which charge moves in only one direction and Alternative Current (AC) in which charge moves one direction and then moves in opposite direction. Both DC and AC can cause an accident and destroy property and equipment in workplaces and also can cause injury to the living tissues. Injury occurred by the shock of electricity depends on the magnitude of current.
Electrical Concerns-
Resistive heat and electrical shock are not only the hazard associated with the electrical power related equipment and devices. Charge moves as a current spontaneously. The sparks and arcs typically creates current and exists for short period of duration. These charges can still be considered as hazardous (Holt Science 2015).
Dangers of Electricity to living tissues-
The hazards associated with the electricity can cause a fire in workplace. This type of hazard can also cause a serious injury to the human body, significantly cause problem to living tissue and organs. If the human body passed by the current may introduce the following symptoms-
· Shock
· Muscle paralysis
· Involuntary muscle reaction
· Burning of organs and tissues
· Death by electrocutions

Static Electricity-
This type of electricity causes by an imbalance of electrons between two surfaces. The accumulation of charges on the surface as result of rubbing of two surfaces can cause a static electrical shock which is not life-threatening but painful. Static electricity can cause fire and explosion if there is a presence of flammable substances (Comcare 2015).
