Re: Haunted House Coil Use
Hi Gary,
In my opinion, the Boston Museum is either unaware of the possible dangers or
has specifically chosen to shut up about them. There are a lot of legal reasons
why they would. However, warnings are designed to prevent accidents. If a
warning does prevent an accident, then I say display it.
