Our supplier of gas cylinders is a leading supplier of precision calibration gases, which are packaged in portable cylinders for ease of use with no demurrage fees.
Because most cylinders are non-refillable, they must meet requirements set forth in the US Department of Transportation’s Part 39 Regulations. Part 39 prohibits filling these cylinders with toxic gases. In fact, all the mixtures we supply are considered non-poisonous. With few exceptions, all are also non flammable mixtures.
ProDetec Calibration Gas cylinders ship as hazardous material. This is due to the inherent danger of compressed gas and not from a chemical hazard. Once the cylinders are relieved of pressure they are NOT considered hazardous material or waste. Nearly all our gas mixtures contain only a very small amount of a hazardous chemical(s) as a minor component in the gas mixture requested. The fact that it is such a small amount (usually in the ppm range) always precludes the gas mixture from ever being classified as hazardous.
We recommend recycling cylinders. Scrapping cylinders involves some preparation before a metal dealer may accept them. This may include removing the valve and/or piercing the sidewall. Because harmful residue pressure may still be present in a cylinder assumed empty, we never advise a customer to do this preparation work. We perform this operation as a service to our valued customers who want to participate.
Conditions apply so please contact us if you want more in formation on recycling your ProDetec Calibration Gas Cylinders.
