STEPS TO REDUCE
EXPOSURE TO LEAD
High levels of lead in the
body have been associated with serious health problems. There is disagreement
within the scientific community about at what level exposure to lead is
hazardous, but there is no disagreement that high levels of lead absorbed into
the body is harmful.
Lead poisoning is an
accumulative effect caused by taking in more lead into the body than it can
expel. Most adult exposure to lead has been through airborne emissions from auto
fuel, through lead glazed china ware, and through drinking water carried in
Steps have been taken to
reduce exposure through these means. The tackle maker has minor exposure to lead
hazards, but care should be exercised when working with lead just the same.
- Melt lead in a well
ventilated area and exhaust fumes to the outside. Air movement that is
sufficient to carry away the wisp of smoke from an extinguished match is
generally considered sufficient ventilation. Lead melts at 621 degrees (F).
When lead is molten, it releases minute amounts of vapors at a progressive
rate as temperatures are increased. Harmful levels of lead vaporization is
believed to occur at elevated temperatures above 1800 degrees (F). Only
lower temperatures between 700-800 degrees are normally needed to cast lead
hobby parts. Most melting equipment sold to hobbyists will not raise
temperatures much above 900 degrees. Minimize vaporization by operating
melters at the lowest temperature that gives good results.
- Before eating or
smoking, always wash your hands after handling raw lead so that lead dust is
not transferred from your hands to food or tobacco products that could be
- Small children are the
most lead sensitive segment of the population. They are also inclined to put
small objects in their mouths. Keep small children away from your work area.
