4. Introduction
Hazards from Health care facilities:
Biological hazards, such as TB, Hepatitis, HIV/AIDS, SARS;
Chemical hazards, such as, glutaraldehyde, ethylene oxide;
Physical hazards, such as noise, radiation, slips trips and falls;
Ergonomic hazards, such as heavy lifting;
Psychosocial hazards, such as shiftwork, violence and stress;
Fire And explosion hazards, such as using oxygen, alcohol
sanitizing gels; and
Electrical hazards, such as frayed electrical cords
5. Biomedical waste
Any solid, fluid and liquid or liquid waste, including its
container and any intermediate product, which is
generated during the diagnosis, treatment or
immunisation of human being or animals, in research
pertaining thereto, or in the production or testing of
biological and the animal waste from slaughter houses
or any other similar establishment.
6. Background
The safe disposal of Medical waste has been ignored in
Bangladesh. Medical waste is a source of contamination
and pollution to both humans and the environment.
Previous study showed that few hospital staff received
special training on hospital born waste management.
Among the rest almost all even doctors and directors of
many hospitals and clinics, diagnostic centers judged
medical waste as general waste ! ! ! ! !
7. Justification
Hospital is a place to serve the patient but hospital waste is
a potential health hazard to the health care workers and
surrounding environment as well as patients.
In my study I will try to find out the socio-demographic
criteria of hospital staffs handling bio-medical waste. It is
obvious that they are the most vulnerable group regarding
the problem. As a public health worker it is our duty to
protect this huge population and environment from the
hazards of bio-medical waste.
8. Research question
How many hospital staffs are aware of bio
hazards and consequences of bio-medical
waste in a tertiary level hospital in Dhaka
city?
9. General objective
To assess the awareness about the bio
hazards among the hospital staff in a
tertiary level hospital in Dhaka city.
10. Specific objective
To find out how many staff take precaution to protect
them.
To assess the awareness about bio hazards among
hospital staff.
To find out what precautions the staffs are taking to
protect them.
To assess the socio-demographic characteristics of
the hospital staff.
13. Methods and materials
Study design
Descriptive, cross sectional study
Study population
4th class staff of a tertiary level hospital who
are directly related to bio-medical waste
handling.
15. Methods and materials
(contd)
Sample size
The following formula (Daniel, 1999) will be used
n=Z2pq/d2
Here,
Z= Z statistic for a level of confidence (1.96 at 95% of
confidence interval)
P= Expected prevalence or proportion. As there is no
reasonable estimate of any prevalence rate.
q= 1-p
and
d = Degree of error, 5%.
n= Number of sample.

Signature of Interviewer…………………………..
Health care facilities around the world employ over 59 million workers who are exposed to a complex variety of health and safety hazards everyday including:
Only 15% "Biomedical waste" is hazardous, not the complete. But when hazardous waste is not segregated at the source of generation and mixed with nonhazardous waste, then 100% waste becomes hazardous.
