Re: Powerhouse II - Hazardous Material Storage and Handling of Flammable Materials
Dear Marsha,
This letter states the quantities of hazardous materials to be used at the proposed
Powerhouse II facility. The quantities listed below and the removal of hydrogen storage
from the site, will remove the designation of a “Critical Facility’, as per defined by the City
of Fort Collins, from the project.
The following outlines the handling and storage processes of hydrogen for research
procedures anticipated at the proposed Powerhouse II facility:
• Hydrogen produced by hydrolysis or similar method will be disposed of as produced via
venting outdoors (as per any code requirements), burned in outdoors in a non-visible
flare, consumed by fuel cell or similar device.
• Onsite storage of hydrogen will remain at or below quantities regulated by
international fire safety code or “household levels”
• Hydrogen fueled vehicles, such as automobiles, light and medium duty trucks, and
transit buses will be tested onsite and adhere to all fire safety codes and DOT
regulations regarding hydrogen fueled vehicles.
• H2 storage tanks will remain at Powerhouse I until approval of the LOMR.
Flammable Materials:
• Acetylene 1 commercial cylinder at 300 or less std. cu. Ft. volume
• Oxygen 1 commercial cylinder at 300 or less std. cu. Ft. volume
Non-Reactive Gases:
• Compressed Air 500 gal. tank
• Compressed Nitrogen 2000 L. Cryogenic Tank, Liquid
• Compressed Argon 2000 L. Cryogenic Tank, Liquid
• Compressed Helium <20 - 300 std. cu ft, steel cylinders
• Compressed Argon <20 - 300 std. cu ft, steel cylinders
• Compressed CO2 <20 - 300 std. cu ft, steel cylinders
All listed non-reactive gases listed above have been evaluated and are found to be
completely non-flammable, non-toxic, and inert gases. The only hazards posed by
compressed nitrogen, argon, and CO2 are that they can be a simple asphyxiant if they
displace enough air in a confined space and the mechanical energy stored by compression
as with any compressed gas. The only hazards posed by the liquid nitrogen and argon is
frostbite by direct contact and also a simple asphyxiant as they gasify in a confined space
displacing the air.
Please reach out with any questions or concerns.
