Monona,

You are right-on with this answer, but I think it needs expanded upon.  Yes, administrators and teachers need to enforce the rules.  ACS should NOT lead in the defense of enforcing the lack of a written risk assessment with training.  What ACS should do is provide examples of the accidents/injuries that have routinely occurred over the past years with those that continue to occur, with a solid example of what is expected of BOTH administrators and teachers.  If this was done, administrators would know what to look for in the assessment, teachers would know what is expected and could be held accountable if not following the "Lesson Plan incorporating the assessment".  Regardless of OSHA, this would allow a sound legal footing for teachers to be held liable and negligent.  Note:  I am not a J.D., just a safety person.  But I do agree with a previous post that minimizing the reactive ingredients would lesson the risk, but that has to be recognized up front - in the lesson plan.  This demonstration has caused and continues to cause to much harm to youth, maybe a different approach may provide different results.  Great example of needing a high level root cause analysis.  If proven well enough, administrators and teachers would have to take note.

I'm running into a brain block, but wasn't that called the limiting reactant in basic chemistry?  It's been a long day-
