The broom is blind to a flat nail
Construction debris, pallet wood, and tack strips shed fasteners that lie flat in the grain. A broom skates over them. A tire does not. A magnet on a handle, the kind you can buy as a simple shop tool, pulls them out of the cracks without you kneeling on glass. Sweep the ordinary dirt first so the magnet is not coated in dust. Then run it in overlapping lines, including the threshold and the ramp edge. When the magnet is fuzzy with metal, hold a can under it and release the fasteners into the can. Do not wipe them onto the ground. Do not fill your pocket. A pocket empties itself into the cab seat and then into the next driver's hand. The can goes to the scrap or trash pile the attendant names. Ask which one. Do not assume every site wants nails in the metal pile.
Your own screws and the debris screws are the same hazard
If you were tempted to screw a cleat into the floor, do not. Those holes are damage. The magnet is for fasteners the debris left, not a reason to add more. A board you own can protect the floor only if it leaves with you and is not nailed down. After the magnet pass, look at the tires before you roll. A screw in the tread is easier to deal with in the stall than on the highway. Walk the tires again at the rental lot. If you find a fastener in the rubber, deal with it before a long drive. Do not leave it as a slow leak you plan to explain later. Tell the counter if the tire is the rental's and it is injured. Do not guess a repair price.
Empty the magnet before it becomes cargo
A magnet covered in nails is a hazard on the seat and a mystery in the box. Empty it at the site. If the release fails, pull the fasteners off with a glove into the can, not into the bushes. Look in the E-track too. Grit and glass sit in those horizontal slots. A putty knife you own, used gently, gets crumbs out. Vacuum them. Do not bend the track. The magnet will not fit inside a narrow slot, so the knife and the vac finish what the magnet cannot. Photograph the floor after the pass if you are building a return record. Then put the magnet in the cab. A magnet left on the plywood looks like scrap, and the next sweep can throw it in the bay.
Before you go
- Sweep loose dirt, then run a magnet over the floor, threshold, and ramp.
- Release the nails into a can, not onto the ground or into a pocket.
- Ask whether that can goes to scrap or to trash at this site.
- Walk the tires, then put the magnet in the cab before you leave.

Questions people ask
Will a fridge magnet work?
A tiny souvenir magnet will miss most nails. Use a magnet meant for picking up fasteners, on a handle so you are not kneeling in debris. Empty it into a can at the site. The tool goes home in the cab, not into the disposal bay.
The magnet picked up a razor blade. Where does that go?
Do not put it in a loose bag. A sharp belongs in a rigid container. If it is a household razor and the site has a sharps rule, follow that rule. Needles and lancets are a separate stream and stay in an approved sharps container, not in the nail can.
