This and more at my blog: Pallet Craft!

Hello Readers!

Today I am going to share with you the other treatment method used on pallet wood; fumigation using Methyl Bromide. First, I would like to state that using these pallets that have been fumigated using methyl bromide could be extremely dangerous to your health!

What is Methyl Bromide?

Methyl Bromide is manufactured from naturally occurring bromide salts. The Environmental Protection Agency (EPA) considers this gas to be an ozone depleting substance (ODS) that can thin the atmosphere. Most commonly used on strawberries in California, Brominated Vegetable Oil (BVO) used in citrus drinks as a preservative of flavors and in other post harvest applications (that’s right folks, you eat this stuff).

Regulatory Groups

The IPPC (International Plant Protection Convention) in 2002 set methyl bromide as the only fumigant allowed to be used in pallet pest control. The USDA (United States Department of Agriculture) also adopted these regulations in 2005. The National Wood Pallet and Container Association (NWPCA) manages the regulation of this treatment method in the United States.

Treatment

The lumber which will become pallet wood is locked into an air sealed chamber where it is gassed for 24 hours while maintaining a temperature of at least 52 degrees Fahrenheit. The wood pallets are then marked similarly to the following stamp.

My Recommendation

I do not recommend using fumigated pallets for wood working. I do not endorse the use of methyl bromide in any application either. Use heat treated wood instead and save the environment and don’t take any risks!

Its nice that you have your fellow woodworker’s concern in mind, but I did some research, you may be surprised to learn that pallets fumigated using methyl bromide are in no way harmful to your health, aside from possible dust inhalation from already toxic wood species used in constructing the pallet.

Methyl bromide fumigation is only done by professionals in cases where the IPPC stamp is applied, and in such a process the pallets are gassed for 24 – 36 hours in a controlled environment, monitored by gas chromatography equipment. It is not commonly known that these pallets do not even leave the gas chamber until the methyl bromide has dissipated to t remain on the pallets in any measurable quantity.

You may also be surprised to learn that an acceptable ratio of methyl bromide present in FOOD for human consumption was higher than 50ppm as recently as 1970s, when methyl bromide was used as a pesticide in cereals and grains used in food production.

You still may not want to take the chance but if you really like the wood, I dont see an issue re-using it as long as proper safety measures are taken like would be used in the sanding of any wood, ie dust mask.

Just my opinion, but based on scientific evidence. As for funky odors, DONT re-use a pallet if some unknown substance has been visibly spilled on it – that could be a REALLY nasty chemical.
