S
ince the National Institute
for Occupational Safety
and Health (NIOSH) and
Unimin Corp. developed
the Helmet-CAM assessment technol-
ogy, which integrates video and dust
data into an exposure assessment
tool, it has proven to be so effective
for assessing respirable dust expo-
sure that it is now being expanded
and applied to other health contami-
nants, including noise exposure. Re-
cently, NIOSH partnered with Vulcan
Materials Co. to be the first to test
and evaluate the Helmet-CAM system
for noise assessment at its Havre De
Grace mining operation near Bal-
timore, Md. Kelly Bailey, Vulcan's
corporate director of Safety, Health,
and Environment, along with a team
of individuals from his Industrial
Hygiene staff, traveled to the Havre
De Grace Operation to learn about the
Helmet-CAM assessment system and
to participate in this testing. Nine
different Vulcan Material Co. miners
wore the Helmet-CAM system for
approximately a 2-hour time period.
The system included a video cam-
era attached to the worker's hardhat,
NIOSH and Vulcan Materials Co. team up to test how well
Helmet-CAM technology measures miner exposure levels.
