Define the simple electrical hazards properly?
Electrical hazards are part of electricity. This is used in every walk of life even, though it can not be seen, tasted, or smelled only it can feel. Basically, there are two sorts of electricity: static and dynamic. Dynamic electricity is characterized by the flow of electrons through a conductor.

Rules of fire in step-by-step?
Fire is rapid self-sustaining oxidation amid the evolution of varying intensities of warmth and lightweight. This definition indicates that there is a chemical process of decomposition in which the rapid oxidation of fuel produces heat and light. This process makes it the reaction based on the speed at which the two other mid-range common forms of oxidation occur. Corrosion is the example of the slower form, an explosion is an example of the more rapid form.
Exactly Heat Transfer: Conduction, Convection, Radiation?
Heat transfer is what allows a fire to spread. It plays a major role in our loss control efforts because understanding how a fire spreads increases our ability to prevent that spread.
Fire travels through four methods of heat transfer: direct flame contact, convection, radiation, and conduction.
