Going the Extra Mile
Dr. Clint Chapple
was part of the team that presented their progress within C3Bio to the DOE
Technical Review panel in Baltimore, MD.
Dr. Barb Golden
gave a seminar entitled, “The HDV ribozyme has a hybrid engine” in the
Department of Biochemistry and Molecular Biology at the University of Chicago.
She also presented this seminar
in the Department of Chemistry and Biochemistry at the University of
Texas at Austin.
Compressed Gas Cylinder Safety
Compressed gases present both
mechanical and physical hazards. If a cylinder valve is accidentally broken, a
standard 330 cubic foot cylinder at approximately 2600 psi becomes a rocket
attaining speeds of several miles per hour.
The contents of the cylinder
may represent additional hazards due to flammability, reactivity, toxicity or
asphyxiation. Exposure to corrosive gases such as chlorine, ammonia, and
nitrogen dioxide can do irreparable damage to the lungs. Cryogenic gases such as
liquid nitrogen can cause tissue damage from extreme cold.
Make sure the cap is always on the
cylinder when it is not connected to a regulator.
Make sure the cylinder is secured at all
times, even during non-use, with a chain or strap.
It is recommended to close the valve when
the cylinder is not in use to avoid having air go into the tank.
A cylinder should also never be emptied
below 25psi because the residual contents can be contaminated with air (see #3).
Do not expose cylinders to
an open flame or to temperature above 125oF.
