Good for Foundries. Good for the Environment.
Today's lead-free alloys make it possible.
Federalloy castings pass leachate standards for copper, lead
and bismuth as defined by current NSF Regulations, Standard 61, Sections 8
Reduced paperwork requirements for OSHA and EPA lead
programs, which may be eventually eliminated for U.S. foundries.
Low airborne lead levels over eight hour periods are less
than 10 micrograms per cubic meter of air.
Once air levels fall below 30 micrograms per cubic meter of
air, blood lead programs can be discontinued.
No respirators are required of employees working in
environments below 50 micrograms per cubic meter of air with a time weighted
average of eight hours.
When melting Federalloy, the toxicity in molding sand from
lead is less than one part per million. (EPA limit is 5 parts per million.)
That means sand is no longer classified as hazardous due to lead and you can
save money on sand disposal.
