Planning DIY Projects Safely

DIY projects save money and can be very rewarding. Most DIY injuries happen when people rush, skip protective gear, or take on work that really needs a professional.

Before you start

• Permits: check with your city or county. Electrical, plumbing, structural, roofing, decks, fences, water heaters and HVAC often need permits and inspections.
• Call 811 a few days before digging anything, including fence posts, trees and garden beds. See Call 811.
• Old house? Homes built before 1978 may have lead paint; before about 1980, asbestos. See Lead & Asbestos.
• Read the instructions for every tool and product.
• Gather PPE: safety glasses, gloves, hearing protection, dust mask or respirator, sturdy shoes.
• Plan for kids and pets: keep them out of the work area and lock up tools.

Know when to hire a pro

Consider a licensed professional for:

• Electrical panel work, new circuits, or anything you’re unsure about
• Gas lines and gas appliances
• Structural changes: removing walls, cutting beams or joists
• Steep or high roofs, and tree removal near houses or power lines
• Asbestos removal and large lead paint jobs

See Hiring a Contractor Safely.

While you work

• Turn off power at the breaker and confirm it’s off with a tester before electrical work.
• Ventilate when using paints, adhesives and solvents.
• Take breaks. Fatigue causes mistakes.
• Clean up as you go. Nails and scraps cause injuries.
• Have a phone and a first aid kit nearby, and let someone know when you’re on a ladder or roof.
