# Electrical Safety
Electricity is one of the Focus Four — and contact can be instantly fatal. Treat every circuit as live until proven otherwise.
## Core protections
- **Lockout/Tagout (LOTO)** — de-energize, lock, tag, and **verify zero energy** before working on equipment.
- **GFCI protection** — Ground-Fault Circuit Interrupters on construction-site power protect against shock; or use an **assured equipment grounding** program.
- **Overhead power lines** — keep yourself, ladders, scaffolds, and equipment a safe distance away; assume lines are energized.
- **Inspect cords and tools** — no damaged insulation, missing ground pins, or wet connections.
## If you're not qualified
Only **qualified** workers should work on or near exposed energized parts. When in doubt, stop and get a qualified person.
**Takeaway:** Treat every circuit as live: use LOTO and GFCI, keep clear of overhead lines, and leave energized work to qualified people.
> ⚠️ *Educational overview — this is **not** official OSHA certification. Get OSHA 10/30 training from an OSHA-authorized trainer, and always follow your employer's safety program and current OSHA standards (29 CFR 1926 for construction).*
