Originally, Section 612 was limited by ozone-depleting chemicals. However, after passing regulations to phase-out R134a, an HFC refrigerant with no ozone-depleting potential, this phase-out was defended by a subsidiary of DuPont siding with the EPA as it was challenged by a major manufacturer of R134a, and was struck down in 2017.
Statewide smoking ban: On January 1, 2008, the Smoke Free Illinois Act went into effect, banning smoking in all enclosed workplaces, including bars, restaurants, and casinos, and within 15 feet (4.6 m) of such places; exempts certain retail tobacco stores, private and semiprivate rooms in nursing homes occupied exclusively by smokers, enclosed ...
1,1,1,2-Tetrafluoroethane (also known as norflurane (), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming ...
PEN America, a free speech advocacy group, found that book bans nearly tripled during the 2023-2024 academic year with over 10,000 books banned in public schools.
Illinois lawmakers in 1994 stopped the practice in public schools. Among states that have completely outlawed it, New Jersey took the unusual step of barring corporal punishment in all schools in ...
R-12 was used in most refrigeration and vehicle air conditioning applications prior to 1994 before being replaced by 1,1,1,2-tetrafluoroethane (R-134a), which has an insignificant ozone depletion potential. Automobile manufacturers began phasing in R-134a around 1993 [citation needed].
Dichlorodifluoromethane (R-12 or CFC-12), the most commonly used Freon brand refrigerant prior to its ban in many countries in 1996 and total ban in 2010. 1,1,1,2-Tetrafluoroethane (R-134a or HFC-134a), one of the main replacements for the formerly widespread R-12. Opteon halogenated olefins now replacing Freons in many applications.
