Approved tarpaulins for methyl bromide field funigations
Title 3, California Code of Regulations, Section 6447(e) requires that tarpaulins used for methyl bromide soil fumigations in California shall have a permeability factor between 5 and 8 milliliters per hour per square meter per 1000 ppm of methyl bromide at 30 degrees Celsius …
Methyl Bromide - an overview | ScienceDirect …
All types of commercial and residential structures may be fumigated with methyl bromide to control or eradicate pests, such as termites. The structure is covered by a “tent” or tarpaulin, and methyl bromide gas is released inside the structure. After a specified period, the tarpaulin is removed and the structure is aerated until concentration of methyl bromide inside the structure reaches safe levels.

Methyl Bromide: Acute Exposure Guideline Levels …
Worker exposure may result from leaks in the stone sheets or tarpaulin or from failure to allow adequate time for the methyl bromide to dissipate following fumigation . The data from these accidental exposures are generally old, and concentration measurements were either not made or conducted using outdated analytic techniques. Regardless, estimates of concentrations leading to …
An Unusual Exposure to Methyl Bromide Leading to Fatality
Methyl bromide used in this fashion is usually safe, but it is a potent biocide, capable of killing insects, nematodes, fungi, and humans. Previous cases of fatalities from unauthorized entrance into the tented home have been reported. However, methyl bromide is capable of seeping through underground conduits from the fumigated area to adjacent struc- tures. In one unfortunate case in Norway ...
Bromomethane - Wikipedia
Bromomethane, commonly known as methyl bromide, is an organobromine compound with formula CH3Br. This colorless, odorless, nonflammable gas is produced both industrially and biologically. It has a tetrahedral shape and it is a recognized ozone-depleting chemical. It was used extensively as a pesticide until being phased out by most countries in the early 2000s.

Methyl bromide fumigation
Tent or tarpaulin fumigation can be performed by using cloth coated with ethyl cellulose, vinyl resin, or other similar coating materials. Ordinary canvas duck tarpaulins apparently do not retain methyl bromide sufficiently well to insure satisfac-tory fumigation. Refrigerated freight cars and trucks make good-7-fumigation chambers. Other enclosures that would normally be too leaky, such as ...
