Cranes

I got a request to start a new thread on the Crane standard, but since I'm an IH and don't have much crane experience (and no experience yet with the new standard) I'm posting the request here in the hopes that others can bring about a discussion:

I have a suggestion for a new blog thread. Why has OSHA adopted new technology for insulated links for use with cranes without doing sufficient research and testing. Look what happened when NIOSH tested proximity warning devices, they failed miserably. Now even though they are still mandated in subpart CC, OSHA admits they are flawed and does not require their use. OSHA should do the same for Links and ask NIOSH to study and test their performance, use, maintenance, and the reliance issues that may occur with thier use.

Also, OSHA should look at how UL went about writing a standard, and how one provider is now marketing that his product meets Subpart CC, even though OSHA stated in the preamble that there are no NTRL's approved by OSHA to certify links.
