I found the above image in the TX year end video, thought it was funny/concerning, added the graphic comment, reposted it there, and received the following comments:
I keep mine pinned there as well. I know lots of folks who do this.
I only consider it a major issue if it is pinned at the bottle.
Having the pin in at the Handle is a good idea. It doesn't take any effort to pull it out and it's a disaster when it goes off accidentally not to mention a huge mess and pain to clean up haha.
Rather than contaminate that thread, I am following up on it here.
I'm interested in hearing opinions from others.
I do not believe it is a good practice to leave the safety pin in the fire system during a race.
I had to go back and review the CMC Rules and CCR. Both comments are right in that there is no specific requirement in either the CCR or CMC Rules stating the safety pin designed to keep the system from being accidentally discharged must be removed for a race. There is also no specific requirement that the extinguisher/discharge handle be easily accessible to anyone but the driver, even though it must be clearly labeled both inside the car and outside the car at the closest access point. I see the labeling requirement as an assumption that it would be beneficial for safety crews to know where it is, which would also make the assumption that they shouldn't have to go through an extra step other than just pulling the handle to make it work.
Unless I've stumbled upon my first RCR for 2014, I believe the various manufacturers installation instructions are clear enough about this that it shouldn't have to be specifically included in either the CCR or CMC rules.
A quick Internet search of instructions on three different systems yielded the following:
Important: The safety pins must be
removed before the vehicle enters
the track. Failure to do so will
prevent the pull cable from
� SAFETY WARNING Failure to remove
safety pin will render the system
inoperable when required.
Please make sure all safety pins are in place and only removed at the
track to avoid accidental discharge during maintenance or moving. Please remember that the safety pins need to be removed while the
car is on the track in order for the system to operate.
