The noise attenuation properties of aviation helmets
and headsets play a key role in reducing permanent
hearing loss. Research on hearing loss as it
relates to flight hours, exposure and types of protection
has been published by Fitzpatrick (1998) and by Gordon,
Ahroon and Hill (2005). Those studies suggest there was
known hearing loss over many hours of flight time with
hearing protection. The purpose of this study is to evaluate the utility
of these devices among aeromedical crewmembers and identify any
improvements in hearing protection.
Over the past decade, occupational
injury rate reductions have primarily
affected low-severity incidents,
while serious injury and fatality rates
decline more slowly.

What is better, online training or in-person training? This is a question I receive often from
managers, supervisors and staff. The answer is simple: It depends. When considering all of the factors presented
here, the authors agree with Wayne, and where possible,
recommend a hands-on approach to training in which
learning is accomplished by doing.
The March 2016 issue of HealthBeat discusses how
workplace safety programs require diligence in
the full circle of hazard identification, assessment
and control. However, controlling a hazard requires
more than the implementation of a physical hazard control
or process. For example, purchasing equipment to
handle patients does not actually control the hazard; it
simply provides the tool to do so. In
the same regard, developing a procedure
for highly infectious disease
exposure prevention does not control
the hazard, it simply provides
the process by which to do so.

•Humanistic behaviorism is explained as a way to enhance the beneficial effect
of behavior-based safety and nurture an injury-free workplace.
•The article illustrates the history and progress of Actively Caring for People,
a process that aims to cultivate a compassionate culture in which people
routinely surpass the norm to benefit the safety, health and well-being of others.
Printing in three dimensions (3-D printing) constitutes an emergent technology for producing
objects made of metals, biologicals and polymers. Already used in several industries,
the process holds promise for larger-scale commercialization and, thereby, elevated worker
exposures to process hazards. This article examines some of those hazards
specifically. •This article frames the present state of 3-D printing
and examines the literature
about related hazards.

original findings from a
preliminary hazard assessment

The Body of Knowledge project is dedicated to creating a living reference that represents the collective knowledge of the Safety, Health and Environmental profession. While the preliminary work has begun, there is still more to do. The purpose of this website is to introduce subject areas that will eventually be part of the Body of Knowledge, and to gather feedback on the future direction, and ongoing assessment of what needs to be completed.
