Introduction
Having a safe work place is one of the most
important aspects that the employees should
consider about it.
However, some people take hard jobs such as
cleaners and housekeepers.
Description of the case
study
In the shower cleaning
using a hose that is attached to an industrial sink,
in the custodial closet .
A very long, heavy hose, presents a risk of
tripping and falling the custodian
requires extra pressure and effort to Bend down,
pull or lift the hose to coil up It.
Injury causes
According to various it has been mentioned that
a neutral spine under compressive load results in
bony failure.
Disc herniation is a very uncommon occurrence
whenever the motion unit compressed in a
neutral posture
It could be linked to the bending down with the
intension of pulling the hose into specified
positions or to lift and pull it to coil up
Recommendation for
improvement of the working
condition
A recoil hose
It is handy
1. Small
2. Lightweight
It is ergonomic
1. Do not need extra effort to bend, unwind and rewind.( stretches by pulling, shrinks by leaving)
2. It stores easily
A recoil hose
it is not long or heavy
That reduces the risk of falling or tripping.
It is spring loaded
That eases the task of cleaning
By eliminate the need of lifting, bending and rewinding.
It has a handle
That makes it easier to transport the hose from place to another
A recoil hose

Conclusion
At the end,
using this new designed hose will improve the
efficiency of the custodian performances and will greatly minimize the probability of having injury in
the work environment.
