----------------------I've seen many decent posts and blogs dedicated to re-purposing free forklift pallet wood, and even a few half-decent posts dedicated to instructing you on what pallets to use, and which to avoid (the one's sprayed with fungicides). I've also noticed that every one of these articles I've come across has neglected to include any visual aids as to what, branding-wise, you should look for.
So here it is, plain and simple....
A PALLET LIKE THIS IS OK TO USE....granted, if its been left outside for sometime and is developing mildew and mold from its exposure to moisture, you'd still want to pass on it, but "HT" is a good thing.
A stamped "HT" means that the pallet has been "Heat Treated" and not sprayed with, well, poison
One stamped "MT" signifies that the pallet has been sprayed with Methyl Bromide.....and lets just say you don't want to lick those type pallets or build a crib for infants from them....or make garden bins for your edibles out of them either (something I see ALL the time, and out of pressure-treated wood too- a no, no).
Also keep in mind that as pallets weather or age, their branding fades. In those cases, if you're worried, or hesitant, its better to play it safe and pass them up (esp. if the destined project is an INDOOR piece of furniture) .
Above: A nice clean pallet, in good shape, and marked "MT", that is ready to be re-purposed.
