Safety on Workshop

Core Idea: Tools in general are widely used to make a work more effectively and efficient. It is
vital to familiarize and fully understand the uses of hand and machine tools and other instrument
to have accurate result on maintenance and other works onboard.

There are a lot of works and repairs that need to be done onboard ship and each has specific tools
to be used as well as the dangers that may arise.

Common Terms to be Familiarized

Machine Shop are simply the location or place where machining or cutting of raw materials that
are subject for conversion into desired size and shape. This is commonly done on metallic parts,
but this also involves plastic, ceramic, and other materials.




Bench Work technically makes a machinist to carried out a work by hand in a bench, where the
assembling of parts via filing, chipping, sawing, etc. are done; and that are usually involving
small tools. This part of the process is essential to successfully complete a job with great
accuracy and precision.

Machine Tool Operation involves the process of distortion of usually metals and other hard
materials by the process of cutting, grinding, or shearing. This includes different tools for each
process.

Inside the Machine Shop

Machine operation is a such a intricate work that also impose some challenges and dangers if
precautions and safety measures are not observed. Therefore, when working inside a machine
shop, there are several terminologies that need not only to be remembered but also embody.

Safety entails a state of a person being secured and away from danger, risk, or injury. Sure, an
explicit and flawless work is the aim, but safety should be the top priority in any circumstances
that may arise inside the workshop. In connection, untoward incidents and accident may be
avoided when risk assessment is practice.

Risk assessment allows the person to evaluate the potential risk that may arise in a projected
undertaking, in this case inside the workshop. This critical process involves the following
components;

, 1. Hazard identification allows to identify the existing and potential hazards. For example,
an exposed electrical cord may cause electrical shock when a person accidentally step on
it or touch it.
2. Risk Analysis is where the existing and potential risk are being comprehended to
determine the level of risk it can contribute on the workshop. This provides a vital
information for the next two components of risk assessment.
3. Risk Evaluation attempts to compare the risk against the criteria to determine its
severeness if ever it happens.
4. Risk Control and Hazard Elimination - upon identifying and determining the
significance of a risk, this will be addressed to minimize the level of its risk or eliminate
it at all.

Risk Assessment helps to develop control and precautionary measures for workers that
will create a safer and more productive workshop.


Risk can be easily avoided when workers in the machine shop has unified safety culture.
Safety Culture is the collective values, perception, competencies, and behavioral patterns of
every individual that contributes on how risks are being handled inside the workplace. This plays
a big influence on the safety of everyone. Failure to have a healthy and communicated safety
culture may result to widespread and often dangers.

As mentioned above, machine shop works can really be dangerous and can result from
minor to major injury, from a small bruise to serious death and life scenarios - these are
commonly caused unintentionally and unexpectedly known as accident while incident is any
occurrence in the machine shop, for improvement or not, essential or not that happens each day.

Near miss is an unintentional sequence of event that could have caused massive damage
or injury but was fortunately avoided. In a workshop, this can be caused by human error or the
system itself.
