NUCON International Inc., Columbus, OH, a worldwide leader in providing
gas, vapor and liquid phase adsorption solutions to the Nuclear Power
and other industries, has announced the results of recent tests to
determine the levels of mercury vapor that accumulate in mercury lamp
storage and shipping containers when lamps inside the containers are
broken. The study concluded that mercury vapor levels within containers
containing broken fluorescent lamps exceed health and safety exposure
limits and guidelines. NUCON also ran parallel tests using a new
adsorbent technology and achieved more than 95 percent mercury vapor
reduction within the same containers.
Tests were conducted by breaking fluorescent lamps inside a sealed
vapor-containing bag and box in a specially designed test chamber and
continuously measuring vapor levels inside the bag. The results
indicated that opening a package containing broken fluorescent lamps
and/or CFLs presents a significant risk of mercury vapor exposure,
potentially rising well above both the OSHA 8-hour permissible exposure
limit of 100 ug/m3 and the NIOSH (National Institute for Occupational
Safety and Health) IDLH (immediately dangerous to life and health) level
of 10,000 ug/m3.
NUCON ran multiple parallel tests using a new, patent-pending adsorbent
substrate they developed in conjunction with VaporLok Products, LLC,
Mankato, MN, www.vaporlokproducts.com.
The new substrate was impregnated with carbon and treated with a
variety of inert chemicals, effectively adsorbing and capturing the
mercury vapor. This new, carbon-based adsorbent technology, called
VaporLokCapture™, is designed to adsorb mercury vapor from any
device or product containing mercury. You can view a short animated
