# Construction Safety Basics
Construction is one of the most dangerous industries — and almost every serious injury is preventable. Safety is **skill #1**.
## OSHA's "Focus Four"
The four hazards that cause the most construction deaths — learn to spot and avoid them:
1. **Falls** — from roofs, ladders, scaffolds, openings (the #1 killer).
2. **Struck-by** — vehicles, falling objects, swinging loads.
3. **Caught-in / between** — trenches, machinery, materials.
4. **Electrocution** — contact with power lines or live circuits.
## Protect yourself
- **PPE** — hard hat, safety glasses, gloves, boots, hi-vis, plus hearing and respiratory protection when needed.
- **Fall protection** at height; inspect ladders and scaffolds.
- **Look out for each other** — report hazards, follow lockout/tagout, keep the site clean.
**Takeaway:** Know OSHA's Focus Four — falls, struck-by, caught-in, electrocution — and wear your PPE. Going home safe is the job.
