Here's another problem that involving the BTHL tournaments this year:

Good thing nobody was seriously hurt.

It is a very good thing no one was seriously hurt. One thing to keep in mind is that this is not the first time something like this has happened at a tournament. Many rinks have had this problem.

It is not a good thing that happened but hands off to the rink and BTHL for making the right calls and keeping everyone safe.

We had two games in Louisville this weekend (Columbus Stars Bantam AA). About 3-4 parents
and 4-5 kids were complaining of headaches after the morning game, but everyone was feeling better after a few hours outside on the lawn at the hotel, so we didn't think anything of it. Our second game (6pm) was on the rink that had the problem, and after that game almost all of our kids were complaining about feeling funny, headaches, etc. But we really didn't make the connection. Cincinnati AA1 and
Northern Kentucky had the game after us on that rink, and it was in that game that the referee figured out there was a problem in
the middle of the second period. They called
the fire department, and immediately cleared the rink. Apparently several Cincy players were taken to the hospital, with one staying overnight.

After examining the rink, it was cleared to play on Sunday. But apparently the problem
persisted, and they had to clear the rink again.
I've not heard what the cause was determined to
be.

I'm glad someone figured it out -- we probably
never would have realized it ourselves.

According to the article, it was the zamboni.

"...It appears the problem was caused by excessive emissions from the rink's Zamboni ice-resurfacing machine, which is powered by propane gas. The Zamboni machine was used much more frequently than normal during the tournament, Richardson said.

Saturday night, management suspected something different "” a malfunctioning heater. But that was ruled out because the heater was turned off yesterday, Richardson said."

My son was in net that game & I was assisting with the scorekeping. It was the parents of one of the Louisville players - both MDs - who were alerted to symptons the Louisville players had after their game (just before the one that was stopped). Fortunately they went home, came back with a portable in-home detector and found the high readings. They (or the rink manager) called the Fire department and the father came to benches to inform the coaches to be alert if any of their players were complaining about headaches. Fortunately it was right at the end of the 2nd period and the officials were at the scoring table. Once the officials were notified they immediately sent the boys to the locker rooms. The FD then evacuated the building.

All of this prompted me to do some research about CM problems and rinks and I found that only 2 states (MA and IL) have state health regulations which require CM monitors in rinks and require rinks to register info about their zams, etc.

Should the BTHL look into requiring facilities to have such monitors as a provision to being allowed to host BTHL games?
