Electrical resistance

Hazards

• Opposition to electric current, measured in ohms for direct-current analysis.

Controls

• Do not rely on skin, dirt, or improvised materials as protection; use rated insulation, isolation, and grounding.

Personal protective equipment

• Select task-specific PPE only after hazards and higher-order controls have been evaluated.

Regional considerations

• Applicable law, permits, collective agreements, venue rules, and qualified-person decisions take precedence.

In practice

Do not rely on skin, dirt, or improvised materials as protection; use rated insulation, isolation, and grounding.
