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.
