What type of Gas Cylinder should I use?
Gas cylinders should be purchased in the smallest size required for your research project. Most RETURNABLE cylinders are acceptable to buy. If you are not sure if your container is returnable, then just check with the supplier, like Matheson Valley Gas. MATHESON TRI-GAS 903 THOMPSON RUN RD WEST MIFFLIN, PA 15122 Phone No. 412 (459) 1411
What potentially hazardous gasses are restricted to order?
Consult the EH&S Guideline for Health Hazard 3 and 4 gases (http://www.ehs.pitt.edu/
If you have any questions please check with Pitt EH&S (412) 624-9505.
Are the cylinders that I typically purchase — Nitrogen, Argon, Helium, Oxygen — okay? If so, then I just need to check in with EH&S regarding the mixes or non-standard tanks.
Yes, Argon, Helium, and Nitrogen are Inert gasses; Oxygen can be an Oxidizer.
An example of a problem is Propane; as you know grills use this flammable gas. Propane is limited to one pound cylinders and EH&S should be consulted prior to ordering propane.
Nitrogen dioxide is the toxic gas that a research group had problems receiving after ordering it, and so they just isolated as a reaction product for their needs.
Chlorine is probably a nice example of a poisonous gas, as with poisons they say it’s the dose. In low quantities it is safe; we smell Chlorine at the swimming pool and have it in tap water. If you plan to order any of hazardous gasses please check with Pitt EH&S (412) 624-9505.
