Re: Elimination of Lead




in general, all uses of lead impose a demand for lead, either as a
primary or secondary product from mining through smelting.  These
processes are as yet poorly controlled.  This facility may have
admirable facilities for managing wastes and recycling, but no info
was given about worker protection.  Occupational lead poisoning
remains a serious and prevalent problem in the US.

    A manufacturer of gas meters makes some small parts out of a
    generic "white metal" containing about 30 percent lead.  All
    in-process metal wastes are recycled in-house.  All out-of-service
    meters are either repaired or recycled.  The manufacturer would
    like to eliminate the use of the high lead white metal for a
    tin-based replacement.  The problem is finding a pressing reason
    to change current operations and eliminate the lead.
    ******************************************************************
    Is anyone aware of any pressing regulatory demands for elimination
    of the lead?  (like by the year 2000? or similar stuff)

    Any pressing OSHA requirements which may make worker exposure
    levels more of a concern? (currently not an issue at the facility)

    Any regulations which may make the leaded metal hard to come by
    for production thereby forcing a change??

    Is anyone aware of any web sites that discuss lead and may address
    reasons to eliminate lead (other than from paints or in
    construction)?
