W6 A1 Reflection Paper
1.
Key Points:
A)
Repetition of single movement is a major cause of CTD’s [ CITATION
Occ00 \l 1033 ]
Repetition of single movements combined with awkward or poor body
positions and high forces can cause damage to nerves and tendons over
prolonged periods of time.
B)
Hand Arm Vibration Syndrome (HAVS)[ CITATION Tho03 \l 1033 ]
HAVS is caused by the exposure of vibration to one’s hands and arms
in the workplace. Depending on the duration and intensity of the
exposure goes hand in hand with how severe the HAVS can be. CTS
(carpel tunnel syndrome) can also be the result of hand vibration
exposure.
C)
Hand tools and other methods that can help reduce the risks of vibration
exposure.
ISO 10819 involves the use of antivibration gloves in hopes to reduce
vibration exposure to the hand and arms. [ CITATION Tho03 \l 1033 ]
Work at a safe pace.
Take breaks.
Change your body movements so they are not repetitive.
Take time to adjust
Train workers! [ CITATION Pro12 \l 1033 ]

Reflection:
HAVS is a very real syndrome that is caused by the exposure of vibration to the
worker’s hand/ or arms. The “good” news is that HAVS can be partially or totally
reversable when it comes to the neurologic side as well as the vascular side of the
syndrome. Unfortunately, there has not been a vibration threshold that has been
determined to be deemed safe or unsafe by a safety agency[ CITATION Tho03 \l
1033 ]. So, in my opinion it is better to be safe than sorry when it comes to vibration
exposure in the workplace. It is important to train new hires as well as annual training
about HAVS and how to reduce exposure. Symptoms of HAVS include pins and
needles, numbness, loss of finger sensations and dexterity, and “white finger”. This is
why it is important to treat vibration exposure just like any other safety hazard within
the workplace.

Application/Problem Solving:
It is important to train new hires as well as annual training about HAVS
and how to reduce exposure. When referencing the Intervention to Minimize
Hand–Arm Vibration Hazards article, it reflected on an awesome case study that
used medical surveillance on a group of workers that were exposed to and/or had
HAVS. These workers were given antivibration gloves during the study to see if
they played a part in reducing the exposure of vibrations. After two to three years
the results of the case study seemed to draw a positive correlation between the use
of antivibration gloves, ergonomic changes (replacing older tools with newer
tools),and the reduction of HAVS cases amongst workers[ CITATION Tho03 \l
1033 ].
