Laboratory waste management in medical and health universities must follow regulations and guidelines to properly handle and dispose of waste. Regulations in Malaysia are set by the Department of Environment and classify waste as clinical, radioactive, chemical, or general. Waste must be segregated by color-coded containers and properly labeled. Proper procedures include contracting licensed services for disposal. Students should be trained on guidelines to mitigate health and environmental risks. While Malaysia has regulations, its management system could be improved compared to international standards by more strictly enforcing rules.

2. Who is the Authority that
generally regulate “Laboratory
Waste” ?
Malaysia
• Department of
Environment
INTERNATIONAL
The California
department of toxic
substance

3. State the specific names of the
Act/Regulation for “Laboratory Waste” ?
• Management of
Clinical Waste in
Malaysia
• Environmental Quality
(Scheduled Wastes)
Regulations 2005
• California Medical
Waste Management
Act of 1990

4. General Definition of “Laboratory
Waste” based from the
Act/Regulations?
• MALAYSIA
• Healthcare wastes
Solid and liquid waste arising from
healthcare (including
collected gaseous waste).
• Hazardous healthcare wastes
Biological (recognisable
anatomical waste) and
pathological waste, chemical,
toxic or pharmaceutical waste
including cytotoxic drug; (anti-neoplastics),
sharps (e.g.
needles, scalpels) and radioactive
waste.
INTERNATIONAL
Laboratory Waste includes
biohazardous waste, sharps
waste, and waste which is
generated or produced as a
result of diagnosis,
treatment, or immunization
of human beings or animals,
in research pertaining
thereto, or in the production
or testing of biologicals.

5. • CONT MALAYSIA
• Iv. Infectious healthcare wastes
All healthcare waste known or clinic ally assessed by a
medical practitioner or veterinary/surgeon to have the
potential transmitting infectious agents to humans or
animals: -
a. discarded materials or equipments contaminated
with blood and its derivatives, other body fluids or excreta
from isolated infected patients.
b. laboratory waste (cultures and stocks with any
viable biological agents artificially cultivated to significantly
elevated numbers and infected animals from laboratories).

6. The Categories/Group of
laboratory wastes?
MALAYSIA
• Wastes from hospitals
and healthcare
establishments can be
categorized into the
following types:-
i. Clinical waste;
ii. Radioactive waste;
iii. Chemical waste;
iv. Pressurized
containers; and
v. General waste.
INTERNATIONAL
• Specimen cultures from medical
and pathological laboratories
• Stocks of biohazardous materials
from research
• Clinical and teaching laboratories
• Human blood
• Surgical specimens
• Other waste materials that are
found by the administering agency
or the local Health Officer to pose
• A threat to human health or the
environment.

7. List a few
Association/Societies/Boards/Counci
ls that also responsible to overview
“Laboratory Wastes”
• Ministry of Health • California Biomedical
Research institution

8. List several of the
Procedure/Guidelines/Standards
for “Laboratory Wastes”?

9. MALAYSIA
WASTE SEGREGATION
• It is the responsibility of nursing and clinical staff to ensure that segregation of
clinical waste is carried out at sourc e and that all clinical wastes are deposited
only in yellow bags and sharps in sharp bins only.
• All healthcare establishments in Malaysia shall adopt the following standard colour
coding which is widely accepted:-
Black : General wastes
Yellow : Clinical wastes for incineration only
Light blue : Wastes for autoclaving or equivalent treatment16 before ultimate
disposal
• Clinical waste requiring autoclaving , or other equivalent treatment, before
disposal shall be stored in light blue autoclave bags before such treatment but
should be placed in yellow plastics bags after treatment.
• Containers/bags in these colours shall only be used for the disposal of clinical
waste and not for the transportation of other items, such as heavily contaminated
linen to the laundry. Care should be taken to avoid confusion with other sorting
systems which may use colour coding or identification, such as a laundry system.

10. LABELLING AND MARKING
• All bags and drum containers must be identified at the point
of production and should be indelibly and clearly marked with
biohazard symbol
• For storing of waste in container, appropriate label should be
pasted onto the container. The date when the scheduled
wastes are first generated, name, address and telephone
number of the waste generator shall be included in the label.
• Labelling can be done in a number of ways: -
• writing the information on the bag or container;
• using pre-printed tape;
• using pre-printed self-adhesive address labels supplied on a
peel-off roll;
• Tie-on tag label, with information written on them;
• Self-locking plastic tags, pre-printed with all the required
information.

11. INTERNATIONAL
• Medical waste is segregated at the point of generation by depositing it
into solid,containers lined with autoclavable bags and marked on the
outside with a biohazard label.
• The containers must have a close fitting lid.
• Biohazardous waste must be contained in bags which are red and
labeled with "Biohazard" or "Infectious waste", the international
biohazard symbol, and are certified to meet strength requirements.
• Storage for untreated, bagged biohazardous waste shall be secured to
deny access to unauthorized personnel.
• Exterior doors will be marked with the international biohazard symbol
• Maximum storage time:
7 days or less when stored above the temperature 0°C
OR
90 days or less when stored below 0°C

12. Identify the
Contractors/Service Providers
that manage the disposal of
laboratory waste for university
o Radicare Sdn Bhd o Stericycle
California licensed
medical waste hauler
and treatment facility

13. Provide a few specific examples of
laboratory wastes in Medical/Health
University
MALAYSIA
Clinical wastes are wastes containing:-
• Human or animal tissue;
• Blood or body fluids;
• Excretions;
• Drugs;
• Pharmaceutical products;
• Soiled swabs or dressings;
• Syringes, needles, sharps;
• Any waste that has come into contact
or been mixed with any of the above
types of wastes;
• Waste unless rendered safe may prove
hazardous to any person coming into
contact with it.
• INTERNATIONAL
• Surgical specimens
human or primate animal
parts or tissues removed
surgically or by autopsy
• Components of blood or
body fluids
such as cerebrospinal
fluid, synovial fluids, pleural
fluid, peritoneal fluid,
pericardial fluid, and
amniotic fluid

19. As a student,what is the MOST important
aspect in dealing with potential laboratory
waste in a University?
• As a student, the most important aspect in
dealing with potential laboratory waste is by
following the guidelines and rules that have
been provided, because appropriate handling
and disposal of laboratory wastes is essential
in order to mitigate against adverse health
and environmental consequences.

20. From your findings , does Malaysia
Laboratory waste management system is
properly in place compared to the
international or other developing
countries ? Please comment
• No,Because compared to international,
Malaysia has poor laboratory waste
management system as example In
malaysia we not strictly following the
regulations on handling laboratory waste
management.

21. In your Opinion , How to sustain a
continuous and the most cost effective
management of laboratory wastes in
Malaysia university
• Train new students
• Give them more information about
dangerous of hazardous waste
• Campaign on laboratory waste
management
• Put a hazard sign at the place where the
chemical placed

22. Do you think this is topic is essential in
your future career ( EH/OSH )? and
Why?
• Essential in future career (EH/OSH)
because we will be working on those area
where we will be handling chemicals too.
• We will learn how to take precaution
measures in handling laboratory waste in
future.
