Methyl Bromide is highly toxic and responsible for ozone depletion and because of this was banned in 1992 as part of the Montreal Protocol, yet there is now contemplation of expanding its use. Disposal of the pesticide is far safer than simply using up what is left, with up to 95% of the chemical eventually being released into the atmosphere, even with the use of tarps covering the crops on which the chemical is used. This pesticide must be destroyed, because it seems that there is no safe way to handle it. It can be very difficult to properly handle methyl bromide. According to the Minnesota Department of Health, there have been numerous poisoning instances around the world with this chemical. These poisoning instances are quite common with the proper precautions. The reasons for these problems, is that, according Minnesota Department of Health methyl bromide, when used in fumigation can leak through pipes, ventilation shafts and windows, allowing it to enter other buildings. Plastic sheeting used to prevent leakage has been shown to be ineffective. Another part of the danger posed by this substance is the fact that it is odorless and colorless. The EPA has set up a list of procedures to limit exposure, but complete safety from this chemical is not possible unless its use ends. All pesticides are dangerous but methyl bromide is worse because of its toxicity and its ozone depletion, which is a major public health problem. While not suffering losses like it has in the past, the ozone layer is still thinning. There is no need to further increase exposure to UV. High UV levels also can damage anything living, including the plants the methyl bromide was originally supposed to protect.Therefore, It is very important that critical use exemptions are not expanded.
