Hand Tool Safety and Maintenance

Hand tools look simple, so people stop paying attention to them. A loose hammer head or a slipping wrench still sends people to the doctor.

Why do hand tool injuries keep happening?

Hand tools are used constantly and rarely examined. Handles dry out, heads loosen, edges chip and teeth wear down, yet the tool stays in the bucket because it still mostly works. When one finally fails, it usually does so under force, with a hand or face nearby.

Maintenance is a small habit that pays for itself. A regular look at your tools, done a few times a year and after heavy jobs, finds problems before they hurt someone.

Farm work adds its own stress to tools: dirt, moisture, cold and irregular use. A wrench left in a truck bed all winter may be rusted and brittle by spring, and a hammer lent to a neighbor may come back loose. Treat every tool that has been out of your sight as unchecked until you look at it.

What should you check on each type of hand tool?

Different tools fail in different ways. A short checklist keeps you honest.

• Hammers and mallets: head tight on the handle, handle free of cracks, striking face not chipped.
• Chisels and punches: no mushroomed heads, which can shed pieces when struck.
• Wrenches and sockets: jaws not spread, no cracks, no rounded corners.
• Screwdrivers: tips shaped properly and handles intact.
• Pliers and cutters: pivot tight, cutting edges aligned, grips undamaged.
• Saws, files and knives: clean, sharp, with secure handles.

How should you use common hand tools safely?

Pull a wrench toward you instead of pushing when you can, and make sure your footing is solid in case it slips. Keep your body out of the line of any tool that could glance off the work. Cut away from yourself and away from anyone nearby.

Use eye protection when striking, chiseling or cutting. Match the tool size to the fastener. A worn or wrong-size tool rounds off bolts and slips, and slipping hands are a leading cause of cuts and bruises.

Keep your free hand out of the path of the tool, and do not hold small work in your palm while you drive a screw or cut. Use a vise or clamp instead. If a fastener is stuck, use penetrating oil as its label directs and the correct size tool, rather than a pipe extension on the handle that can break the tool or your grip.

How do you sharpen and clean tools properly?

Sharp tools are generally safer than dull ones because they need less force. Sharpen edges according to the tool maker's guidance and wear eye protection when you grind. Clean grease and oil off handles so they do not slip.

Wipe metal tools after use and store them dry to limit rust. Remove rust and burrs before they cause scratches or cuts.

When should a hand tool be repaired or thrown out?

Replace cracked handles and do not wrap them with tape as a permanent fix. Do not use a tool with a chipped or mushroomed striking face. Spread or cracked wrenches should be discarded, not reused.

If you are unsure, retire the tool. A replacement costs far less than an injury. Dispose of damaged tools so they do not drift back into use.

How should hand tools be stored and carried?

Keep tools in racks, boxes or on pegboards where edges are covered and heads are visible. Do not leave tools on equipment, ladders or the ground where they can trip someone or fall onto a person below.

Carry sharp tools with edges protected and pointed down. Use a tool belt or bucket to haul tools up a ladder instead of climbing with full hands. Take stock of what you have after big projects so nothing is lost in the field or in the machinery.

How can you build a simple hand tool maintenance routine?

Pick a regular time, such as the start of each season, to go through every tool. Lay them out on a bench, look them over under good light, and sort them into keep, repair and discard. It takes an hour or two and pays back in fewer injuries and fewer frustrations.

Assign a place for each tool and mark the spot with an outline or label. When a tool is missing, you notice at once, and that matters when the missing tool is a hammer left inside a machine or a wrench left on an engine.

Teach young workers the routine as part of learning the trade. Let them sort a pile of tools and explain why each one goes where it does. Confirm youth work rules with the U.S. Department of Labor and your state agency, and keep supervision close when tools are sharp or heavy. Keep a few spare handles and replacement parts for the tools you use most. When repair is easy, people repair; when it is hard, they keep using the damaged tool.
