Which rule is this illegal based on? Looks like <R8>?
What is the definition of hazardous?
Is there a list of hazardous materials? Mercury isn't mentioned in the blue box next to this rule.
If there is no list, does that mean it is up to the individual inspector to judge the hazardous nature of the material?
As such... isn't the legality of this sort of component determined by the lead-inspector at an event?
