JPM75 Posted May 1, 2009 Author Report Share Posted May 1, 2009 nice facts. i didn't realize 150 dbs was so harmful. why did u take this class? Well, I work for OWENS CORNING, I'm the lead guy under our teams supervisor, and we had to take it as a part of the annual safety audit. It sucked balls!!!

savageracer Posted May 1, 2009 Report Share Posted May 1, 2009 I think all companies are doing it at the same time. I have to take a 10hr class once a week for the next 8 weeks for osha. The only good thing is it is all overtime. Quote Link to comment Share on other sites More sharing options...

uhoh_45 Posted May 1, 2009 Report Share Posted May 1, 2009 all must remember this is high pitch noises nothing there is low so 150 db at 30hz makes your tummy feel weird where 150 db at 1000 hz would make your ears bleed Quote R.I.P!

Melissa Posted May 2, 2009 Report Share Posted May 2, 2009 Were you able to stay awake for the class? Sometimes those training classes are great cures for insomnia! Quote Link to comment Share on other sites More sharing options...
