Keeping them working
Five habits, adapted for a household
OSHA sets out five basic safety rules for preventing hazards with hand and power tools.1 They were written for workplaces and they translate cleanly to a garage.
Keep tools in good condition with regular maintenance
Wipe metal dry before it goes back in the case, especially after outdoor work. Rust on a ratchet mechanism is the most common way a good tool becomes a stiff one.
Use the right tool for the job
This is the single highest-value habit on the list, and it is free. When the correct tool is not in the house, the honest options are to borrow one or to wait, not to improvise with the nearest piece of steel.
Examine each tool for damage before use
Do not use damaged tools. Handle tight, jaws true, face clean, tip square. Four checks, a few seconds, done before the job rather than after something goes wrong.
Operate tools according to the instructions
Most hand tools need no manual, but torque wrenches, ratcheting drivers, and anything with a locking mechanism do have correct procedures worth two minutes of reading.
Use the right protective equipment
Safety goggles and gloves are called for to protect against the hazards that come up while using hand tools.1 Eye protection is the one to build a habit around, because the four failure modes in this handbook all end with something small moving quickly at eye height. A pair of safety glasses kept in the tool case costs less than any tool in it.
One addition of our own, which is not a safety rule but is the difference between owning tools and having them. Give the kit a single known location and return every tool to it the same day. A household that can find its adjustable wrench in the dark is better equipped than one that owns three and knows where none of them are.
