INTRODUCTION

Every type of work in this entire world may have the hazard. As
example, physical hazard ,chemical hazard ,ergonomic hazard.
psychological hazard and biological hazard . Also, every action
and place are hazardous. So, that’s why some hazard need to be
studied to avoid anything hazardous happen to us. Furthermore,
hazard things can occur and happen anywhere such as in the
lab, cafe, and lobby All this, depend on the attitude of the person
that can causes undesired incident. In this case study, lab c2
became a preferred place for our group to monitor the hazards
found in the lab. There are 4 hazard which is found including
physical hazard, chemical hazard, ergonomic hazard, and
psychological hazard. Physical hazard is because of things that
causes harm to us, chemical hazard can causes internal and
external health affected, ergonomic hazard that involve position
either stand or sit and psychological hazard that cause tiredness,
stress and depress of someone. The objective of this case
study is to identify the types of hazard that can be observed

anywhere such as laboratory.And also to identify the types
of risk control that can be carried out in order prevent hazard
from happening. Ultimately, is to guarantee the safety for all
PTSN citizens.

DISCUSSION AND THEIR RISK CONTROL:

Research to identify some hazards has been carried out in
the C2 laboratory. There are 4 types of hazards identified
including physical, chemical, ergonomic and psychological
hazard. Based on the HIRARC form, physical hazards that can
cause harmful to our self and others can be seen when there are
sharp tools such as a knife that is not arranged in the right place.
This often happens after students have finished their work and
leave the equipment just like that on the table. Therefore, the
likelihood value obtained is 4. This will cause injury to the hand,
which is a wound and the knife can fall and be hit on the feet.
This matter is very serious, so the severity value is also 4. If
multiplied, the risk value is 16, which is at a medium level. To
prevent this hazard from happening, administrative control plays
a role by pasting the steps before and after completing the work
on the laboratory wall and encouraging students to read and
understand the rules made.

The next hazard involves chemicals, which is chemical
hazard. This hazard often occurs when some students do not
wear gloves and face masks when taking chemicals. Therefore,
the likelihood gets a value of 4. For the severity value is 5
because this matter is very dangerous that can damage the inside
and outside of the body through the skin exposed to acid or

other chemicals. Then the risk value obtained is 20 which is at a
high level. To overcome this problem from happening
continuously, risk control that can be done is to instruct students
to use and wear personal protective equipment,PPE so that
everyone is safe from any incident.

Next is the ergonomic hazard that occurs when there are
students who do not stand up straight and sit by bending over.
This is very often done by students in the laboratory while doing
assignments. Therefore, the likelihood value is 5. If left
unchecked, this will cause the spine and the waist becomes sore
and limp. The severity value is also high which is 5. Then the
overall risk value is 25 which shows the highest level. Because
the risk value in terms of posture is high, the appropriate risk
control is done by the substitution method. Where the student
needs to change the posture stand up to an upright posture and
replace a high chair with a lower one so as not to bend over
when sitting.

The last one is the psychological hazard that occurs when

there are apparatus and materials that are left messy and dirty on

the table after used. This behavior is not done too often, but if it

is done often, it will cause a person to be tired to clean and wash

the equipment. And this may cause fights and disrespect for

each other. Therefore, the likelihood and severity value is low,
which is 3. The risk value is 9, which is at a low level. To
prevent this hazard from happening, isolation is suitable as a
risk control, where the apparatus and the materials used need to
be separated so that the materials are easy to throw away and the
apparatus is easy to wash.The help from others is also highly
encouraged.

CONCLUSION

In conclusion, we identified that many hazard at the Lab C2 will
cause the students injured or death. The hazard conclude are
physical hazard,chemical hazard, ergonomic hazard, and
physiological hazard. These hazard must being remove to
prevent anything happen to student and others.There are some
action that recommended to prevent this problem.For physical
hazard,risk control that must be carried out is administrative
control.For chemical hazard,wearing PPE can be used as an
appropriate measure for risk control such as wearing gloves. If
we not wearing a proper PPE,it can cause injury.Not only that
for ergonomic hazard,standing and sit position is important so
that any injury at the back bone not happen. Also,the broken
chair must being repair to make the students and lecturer sit
properly.This also can cause MSD symptom because of forceful
exertions. Therefore, substitution method can be used as risk
control which position must be change . Last but not least, for
physiological hazard, which is hazard that cause someone tired
and stress because of the things that messy and dirty.Then for its
risk control, isolation is suitable. So as a responsible students,
we must take action to all types of hazard that may happen and
causes incident and then injured. If we take it serious, the
lecturer, laboratory’s assistant and the students always safe
without any hazard.
