Month List

Over the next few weeks, we will be focusing on electrical safety and what to look for when inspecting tools, cords, and other sources that carry electrical current. We start our series by focusing on the basics: electrical terminology.


Voltage - electrical pressure (water pressure)

Resistance - restriction to electrical flow (pipe friction)

Amperes - electrical flow rate (gallons/min)

Watts – amount of electricity used.



There are four main hazards associated with electricity:

  1. Shock
  2. Arcing/Sparking
  3. Explosions
  4. Fires

Shock: A shock can be defined as an electrical current travels in closed circuits; occurs when a part of your body becomes part of an electric circuit; or when an electric current enters the body at one point and exits the body at another

Arcing or Sparking: Arcing or sparking occurs when high-amperage currents jump from one conductor to another

Explosions: Occur when electricity provides a source of ignition for an explosive mixture in the atmosphere

Fires: Electricity is one of the most common causes of fire
