How long does it take for methyl bromide to dissipate from pallet wood?

Methyl bromide has a half-life of 7 days when exposed to sunlight, but in tightly packed pallet wood, it may take longer to dissipate completely. It is recommended to store pallets in a well-ventilated area for at least a few weeks to allow the methyl bromide to break down and disperse. It's important to follow safety guidelines when handling pallets treated with methyl bromide.
