Advanced spout design combined with child-resistant features and emission reducing technology. Features variable flow, automatic venting, automatic locking when lever is released, and an airtight seal when not in use to reduce spills.The California Air Resources Board (CARB) has approved new emission and spill-control regulations for portable fuel containers that came into effect in California on January 1, 2001. According to CARB, traditional gas cans account for about 87 tons of smog-forming pollution a day in California. This is equivalent to emissions generated by about 1 million cars.In response to the new legislation, Scepter Corporation has developed the ECO® Gas Can using patented DuPont Laminar Technology, resulting in permeation levels well below the CARB required rate of 0.40 grams per gallon per day.Scepter has also developed a self-venting spout that automatically shuts off when the gas tank reaches capacity. This spill-proof system prevents the escape of vapours or dripping from the gas can.This can is for gasoline only.
