Dear Prof. Dr. Hülya YAVUZ ERSAN,
This report gives detailed information about risk assessment which made for research
laboratory 5, held on 2nd January, 2019.
The aim of this risk assessment was to analyse and find possible hazards in the
laboratory. After determination of possible hazards, some advices and solutions were given
in order to reduce those possible risks for laboratory 5. All possible risks were defined by
using photos which were taken by permission.
This risk analysis study gave us an opportunity to observe possible risks and possible
accidents while working in a laboratory environment. Given recommendations in this report
may help to reduce the possible risks in the laboratory.
This study helped and informed us for gaining an ability to make risk assessment
which will help us for our working life in a real plant.
We would like to special thank to you and Res. Asst. Anıl KUBAN for your help

SUMMARY
The object of the risk analyses study is to observe the possible hazards in the
laboratory, to find prevention for these risks and to get a knowledge about sketching a risk
analysis table.
In the laboratory-5, some important documents such as emergency plan, laboratory
safety rule, emergency phone numbers, emergency evacuation plan are hanged on the
entrance of the laboratory. There is not any barriers which can hinder the way go out in an
emergency situation. In addition, there are user guides for each equipment and they are
labeled on the equipment to get an easy reachable information for each apparatus.
Even though these given advices and informations there are lot of risks which can
causes accidents like gas escape, chemical scattering, breaking of the glasses, laceration,
poisoning. For instance, some gloves which are used before are placed on the desk,
unchained tanks are on the floor, fume cupboards are useless because of their inner side,
breakable stuffs are placed above a glass case instead of the floor.
Considering all these situations which are positive and negative, risk assessment table
is sketched. In this risk assessment process, possible hazards are identified and danger class
for each risk is determinate by enumerating probability and occurrence of violence.
Eventually, according to all possible hazardous situations in this laboratory some
risks are obtained and after the risk assessment table is occurred, the preventable suggest for
each risk are given.

DISCUSSION
Figure 1. Gas cylinders which is chain to bench
Figure 2. Unused gas cylinder chain
Gas cylinders should always kept vertical as shown in figure 1. These gas cylinders
should chain to the bench or wall to prevent tilt over. Because these gas cylinder has very
high pressure and if its tilt over explosion may occur. These three gas cylinders fixed to the
bench as expected but one of these gas cylinder did not fixed and it might cause some damage
if it tilt over. Therefore this gas cylinder should be fixed on to the bench or wall. In figure 2
there is a unused gas cylinder chain. The chainless gas cylider might put into there if possible
or new chain may be used for the fixed this gas cylinder. Non-compatible gases should be
kept separate.
Figure 3. Emergency evacuation plan for
Figure 4. Emergency phone numbers
Laboratory 5
Some precautions are defined clearly in the research laboratory which are super
critical for safety. These precautions are emergency evacuation plan and emergency phone
number. These documents are hung up to the wall for everyone to see them easily and
directly.
4
The emergency evacuation plan diagram shows the shortest way to get out in an
urgent situation. The emergency phone numbers include most important urgent calls like
ambulance, fire department, poisoning etc..
Laboratory Safety Rule hung up on the
wall as it must be available for all laboratories.
Risk categories and their pictogram signs,
chemical storage matrix, precautions for
laboratory safety, likelihood accidents are given
in this sheet. But in the labeling system old
system pictograms are used. New system
pictogram include both hazard and warning.
Also
new
system
has
the
28
hazard
classification with subdivision. This sheet
include working safely with chemicals and this
table occurred considering with list of the
chemicals, MSDS, labeling and training.
Figure 5. Laboratory Safety Rule
Figure 6. View of a nonclosed fume cupboard
Fume cupboards are a type of local ventilation devices which are designed to
minimalize the exposures and should have a wide space in it to facilitate the handling of
chemicals.
5
As it is seen in the figure 6 the superimposed backers inside the 1st fume cupboard
narrowed the area and because of their unlabeled surface it is not possible to remove them
to enlarge the inside of the cabinet. Also, the tube stand is overturn able because of its
position.
Figure 7. View of a fume cupboard
Figure 7 shows us a more usable fume cupboard than the 1st cabinet. It contains more
available space to use. All the chemicals are labeled and are not imbricated.
Figure 8. Overturned emergency plan
This figure 8 shows that the overturned emergency plan which also includes all
possible emergencies, consequences, required actions, written procedures, emergency
numbers and the resources available. Detailed lists of personnel responsibilities in the
laboratory, but it is unreadable because it is not completely hanged on the wall. In addition,
a lot of waste paper is scattered on the table makes the laboratory impractical.
6
Figure 9. A view of the complexity on the desk
In this figure 9 there are a lot of unlabeled volumetric flask and also some cleaning
materials are placed beside the flasks. The cleaning materials should be removed from bench
after they are used. Since chemicals might be react when the cleaning materials are poured.
The napkin with its cartoon roll must also be removed from the desk and should throwed
into the waste paper box.
Waste collection container should be
used easily. As seen in this figure 10 some boxes
are present on to the waste collection container.
Therefore waste can not be throw away of easily
to the container. There must be nothing on the
lid of the container and reached easily. Also as
shown in figure 10 the boxes had stored
superimposed. The boxes may fall over if some
forces acted on it. Also the cleaning equipment
should be set their proper places. As shıwn in
Figure 10. Waste collection container
figure 10 there was a chemical waste storage
and cleaning equipments
and it provides separated of the chemical waste
easily.

Figure 11. The bench in the Laboratory 5
Figure 12. The used gloves on the bench
In these Figures 11 and 12, untidy bench in the laboratory is shown. There are
beakers, caps, used laboratory spoons and used gloves on the bench. These used gloves may
cause contamination and it may cause some errors in the experiment when they used again.
These used gloves should be rush in the contaminate waste container. Also for preventing
some accident laboratory bench need to be tidy.
Figure 13. The cables in the laboratory
In this Figure 13, messed up cables in the laboratory are shown. These messed up
cables may lead to some accident when people work in laboratory. Also, these cables may
cause fire. The complexity of cables makes the intervention difficult in an emergency. This
situation can make possible accidents more dangerous. The cables must be mounted on the
wall to avoid these accidents.

Figure 14. Desiccator and sink
In this Figure 14, Desiccator is found in the sink. Desiccator which is used for
capturing moisture but this desiccator is not usable in the sink. There is a chemical solution
in the desiccator we should put it suitable place.
Figure 15. A table in the laboratory
Figure 16. Beakers and tubes with thermos
In figure 15 a table is shown with kettle, thermos, charging phone and mask on it.
Thermos and kettle stuffs should be used in the kitchen if it is possible. If there is no kitchen,
they should be used with precaution away from chemicals, since electrical problems can
cause serious damages, especially in laboratory. The mask should not be left on table like
that because it can cause contamination, instead, it should be hung up proper place for it.
9
In figure 16 thermos should not be placed with beakers and tubes. This situation can
cause serious damages, like chemical contamination to human if that thermos is used by
somebody. Also, beakers and tubes should not be left as shown in figure 16. They should be
cleaned up and put proper benches which set for them after experiments are done.
Figure 17. Kettle with experimental instruments
Kettle in figure 17 should not be placed with instruments which are used for
experiments. Again this situation is very dangerous in terms of contamination and any
electrical leakage might cause explosion in the laboratory.
Figure 18. Paper collection box
Figure 19. Left spatula in sink
Waste papers are collected in a box which is a good behavior, however, waste box
should not be placed in the sink. This box should be removed from the sink. The sinks should
only be used for washing purposes.
10
The spatula as shown in figure 19 should not be left in the sink. The used spatulas
should be cleaned up after their specific usage and put a place where it should be belong.
Also, spatula might contain contaminated chemicals which are directly can go to domestic
wastewater.
Figure 20. A bottle of parfume in laboratory bench
Personal cosmetic materials should not be brought to laboratory, at least to working
bench. They should be used away from working place because chemicals in the perfume can
be flammable and could cause fire in laboratory. Also the equipment on the bench may
break down and experiments could go wrong. More importantly those equipments may
explode.
Figure 21. Chemical Samples in the refrigerator
This figure 21 shows that the chemical samples which have to present in the
refrigerator. There are expiration date or date of use on the some chemicals not the all
chemicals. Pre-dating chemicals might be available in the refrigerator and it causes the
confusion.
11
The date should define on the samples which were used before or will use for after.
Contaminants might be occurred on the samples which is not used, therefore chemicals
which is finished to work should send the waste collection container. In addition, the
properties of chemicals should be specified and be placed according to chemical property.
Figure 22. Chemicals without label on the bench
This figure 22 shows that there are some chemicals wtihout label on the bench. In all
laboratory, chemicals should label in order to prevent of occuring complexity. However,
there are not label on chemicals as shown in figure 22 In addition, chemicals should not be
available near the electronical gadgets such as keyboard, analyser, and recorder. Since it
causes damage when the chemicals are poured on these gadgets, also it might react with
another chemicals which is poured.
In figure 23, the box which has
possible to broke causes the damage. It
should not be placed above the floor due
to will be broke. When the box in which
is unknown falls down, chemicals might
be damaged and also broken pieces might
be
scattered
laboratory.

the
Figure 24. The unlocated and unlabeled wastes
In figure 24, a faulty placement of the wastes and a disorganization of the wastes has
been seen. According to the laboratory safety rules, the wastes should be strictly labeled and
placed to the related area for waiting to discharge.Because nonlabeled wastes could not
disposed and discharged; the wastes should be labeled by the standarts.In addition to that,
the labeled wastes should be located at an area where the separated waste area is, while
waiting for the waste discharge team coming to pick them up.
Figure 25. The unlabeled wastes and unsuitable containers
As seen in figure 25, the contaminants are contained in unsuitable containers.From
the quick interview with the assistant in charge of the laboratory, it has been told that the
bottle on the left contains an unknown waste, so they cant discharge this waste. This is
against of the laboratory safety rules and should be examined and the type of the waste
should examined, labeled and discharged to the discharge teams.
13
Figure 26. Disorganized needles and packages
The needles,packages and papers has been left disorganized on the counter of the
laboratory.It creates a potential hazard of getting injured. All of the equipment should be
organized and tidied after the experiments end.The counter should be left tidy and clean
.Packaging wastes should be discharged to the residential waste bin.
Figure 27. Counter of the laboratory
In the figure 27, it has been seen faulty placements of the equipment and some
additional faulty applications. the scissors should be kept in place to prevent any possible
injury.The flasks should be washed and stored at their own place. The solutions should have
been labeled to prevent any confusion about the material that has been worked on.

CONCLUSION
The risk assessment study was done for research laboratory 5 at Chemical
Engineering Department by the help of research assistant Anıl KUBAN.
Some parameters were noted and analyzed by answering the questions which were
written in check list. The degree of risk was analyzed according to the pre-determined
parameters.
According to the result of the Fine-Kinney method the risk anaylsis was done. In
general the laboratory was found as risky for working. The risks were defined and possible
solutions for reducing the risks were given in the discussion part.
In order to prevent possible risks, some recommendations can be given as below;

The working area should be cleaned up. For example, used gloves, waste
papers and christmass tree should be removed away.

Electrical devices should be kept away from working area and cables should
be set up onto wall.

Glass equipments can be stored below instead of above to prevent any
damage.

Pressurized tanks should be chained up.

Kettles or thermos should not be used near by the instruments.

Wastes from experiments should be stored in proper tanks.

All chemicals and waste boxes should be labeled.
By following above recommendations, the risks in the laboratory could be reduced.
As a result this assessment was very helpful to analyse the laboratory occupational health
and safety.
