The whipping un-locked zip-screw hex adapter

High-vibration impact drivers can instantly spit out unsecured bits. Whenever you drop an extension rail or magnetic chuck adapter into an impact driver's chuck collar, tug on the bit firmly with your fingers to verify the spring-loaded ball-detent.

Stop if

• That long driver bit dropped off the gun because you didn't check the chuck collar lock. Tug on your extension bit every single time you snap it into the driver before you lean over the guardrail.

Watch out

• Do not force the tool through the problem or substitute the wrong tool just to keep moving.

Check

• Stop the task if the tool can fall, whip, bind, or kick back.
• Check the bit, chuck, tether, and hand position before starting.
• Use two hands or a tool lanyard when the task creates drop or kickback risk.
• Clear people from the drop zone below.
• Tell the foreman if the setup is not safe to continue.
