Study Notes
Electrical Hazards
- Even low voltages can cause harm, especially if they pass through vital organs or disrupt the body's normal electrical functions.
Danger Signs of Electrical Hazards
- High voltage warning signs
- Signs indicating the presence of electrical arcs
- Signs warning of electric shock hazards
Risks of AC Electricity
- False: AC electricity poses hazards, including electric shock, burns, fires, and explosions, depending on factors such as voltage, current, and exposure duration.
Differentiating AC and DC Electricity Hazards
- AC electricity poses a higher risk of causing muscle contractions and involuntary movements
- DC electricity tends to cause continuous muscle contraction, making it harder to release from the source
