* All products made on or after May 15 must contain highly visible warning labels with the words: "WARNING: Manufactured with (or contains) Methyl Chloroform
(or the name of the ODS), a substance which harms public health and environment by destroying ozone in the upper atmosphere."
As I mentioned earlier, Dow, along with other producers and users, are working to address this situation by eliminating CFCs and emissive uses of methyl chloroform
The shoe sprays linked recently to illness had been reformulated to eliminate 1,1,1 trichloroethane (i.e., methyl chloroform
), an ozone-depleting solvent, from the formula, in accordance with Title VI of the Clean Air Act amendments of 1990(*).
Until recently, silicone dispersions of this type were made by using solvents such as Freon or methyl chloroform
(1, 1, 1-trichloroethane) as carriers for the elastomer.
Causing ozone to be formed, VOCs include all organic compounds except methane, ethane, methylene chloride and methyl chloroform
According to rules proposed by the EPA to meet the accelerated schedule, production of chlorofluorocarbons (CFCs), carbon tetrachloride and methyl chloroform
will be halted in 1996, production of halons in 1994, and production of hydrochlorofluorocarbons (HCFCs) will be phased out by 2030.
The inclusion of 1,1,1 trichloroethane or methyl chloroform
on the list of substances to be regulated under the Montreal Protocol means that there will be a need in the engineering sector to seek an acceptable replacement for this widely used solvent in the next few years.
101-508), Congress added the following 12 chemicals to the list of chemicals subject to the ODC excise tax: carbon tetrachloride, methyl chloroform
, CFC-13 CFC-111, CFC-112, CFC-211, CFC-212, CFC-213, CFC-214, CFC-215, CFC-216, and CFC-217.
Besides, hydro chlorofluorocarbons, chlorofluorocarbons, carbon tetrachloride, and methyl chloroform
are important human-produced ozone-depleting gases that have been used in many applications including refrigeration, air conditioning, foam blowing, cleaning of electronics components and as solvents.
Although challenges remain, the Montreal Protocol has been recognized as a global success, demonstrated by the massive elimination of production and consumption of CFCs (chlorofluorocarbons), halons, carbon tetrachloride, methyl chloroform
, methyl bromide, and bromochloromethane worldwide since it came into force in 1987.
The effect of maternally inhaled trichloroethylene, perchloroethylene, methyl chloroform
, and methylene chloride on embryonal and fetal development in mice and rats.
The quest to replace the evil 1,1,1-trichloroethane (aka methyl chloroform
) solvent and other ozone depleting substances (ODS) with suitable substitutes for parts cleaning by the not-particularly imminent, though inexorably approaching, deadline of December 1995, seems just that--something that can wait.
