1. What color does DIG SAFE use to flag Electric lines?

DIG SAFE uses the color red to flag electric lines. This is a widely recognized color code in the industry for indicating the presence of electric lines. Red is chosen because it is easily visible and stands out against most backgrounds, helping to prevent accidental digging or damage to the electric lines. It serves as a warning signal to anyone who may be working or digging in the area to exercise caution and avoid potential hazards.

2. Padlocks for lockouts must be assigned to two people for redundancy.

True

False

The statement suggests that padlocks for lockouts must be assigned to two people for redundancy. However, this is not true. In lockout situations, it is important to assign a padlock to only one person to ensure accountability and avoid confusion. Assigning the padlock to multiple people can lead to miscommunication and may compromise the safety of the lockout process. Therefore, the correct answer is False.

3. What are the three factors that affect the level of injury from an electric shock?

Current

Path

Time

Power

Voltage

Heat

The level of injury from an electric shock is determined by three factors: current, path, and time. Current refers to the amount of electric current flowing through the body, with higher currents causing more severe injuries. Path refers to the route the electric current takes through the body, as different paths can result in different levels of injury. Time refers to the duration of the electric shock, with longer durations increasing the likelihood and severity of injuries. Therefore, these three factors play a crucial role in determining the level of injury from an electric shock.

7. What PPE is recommended for work around energized circuits?

Tick-stick

Volt meter

Flash Suit

Grounding bar

Grounding cable

Gloves

The correct answer is Tick-stick, Volt meter, and Flash Suit. Tick-stick is recommended for detecting the presence of voltage in circuits without direct contact. Volt meter is used to measure the voltage level in circuits. Flash Suit is a type of personal protective equipment (PPE) that provides insulation and protection against electric arcs and flash fires. These PPEs are essential for ensuring safety while working around energized circuits.
