For anyone still interested in what was the solution to this problem, the attached pictures is what I proposed. Its essentially a piston that will push on the door while the personnel are engaging the Push Bar. Other concepts were proposed but due to NFPA-101 codes, majority of them were...
Yes, the tricky part of this task is that they are indeed fire doors, not only that is this is a Nuke II processing facility, so the doors are also barriers to contain radioactive contamination. If there wasn't enough reduction in options already...
Your analysis is spot on. The plant will be going through an HVAC rebalancing in the not so near future to be the permanent fix for this. In the interim, I've been tasked with developing a stop gap device that provides assistance to getting these doors open (we had a small female worker get...
Hello all,
I have a unique situation where I work at a plant that is equipped with air handling units that are so strong that it makes egress from some doors up to 100 lbs to open. Long story short, I've been tasked with providing assistance to drop this force down to NFPA-101 requirements of...
Sorry for the lack of information, I know it makes helping more difficult. It's government work so there's only so much I can share. I appreciate the feedback from everyone.
A full circular shape profile is definitely plausible, thank you for those suggestions.
Also Compositepro, I checked...
Hey Sal,
To my current knowledge, it'll be more of a dust rather than a gas that will be escaping from the drum. I don't currently have material density parameters at the moment.
Unfortunately, I cannot put holes in the drums in any way since they will be reused to seal other materials in the...
The drum contains highly radioactive material, beyond that I can't share. Workers are in their own breathing apparatus while working around the drums as an intake of this material could be detrimental to their health.
The operators are reaching into the Drum, so I need to keep it as open as...
Hello,
I am working on designing a ventilation system for a 55-gallon drum. The goal is to remove as much contaminated airborne material from this drum as possible. My question is how to determine the point of diminishing returns on the throat opening to the vent device. I currently opened it...
