Public health aims to improve health through healthy lifestyles, disease prevention, and controlling infectious illnesses. Biosecurity encompasses actions, systems, and policies that protect people from harmful biological agents using risk reduction methods like personal protective equipment, laboratory containment systems, and decontamination techniques. Containment has two types - primary protects personnel through good practices and safety equipment, while secondary protects the external environment through facility design and operational practices.

1. What is Public health ???

2. Public health is the science of improving and
protecting health through the promotion of
healthy lifestyles, researching disease and
injury prevention, and the detection and control
of infectious diseases.

3. Concept of Bio-safety
• Bio safety is a term that encompasses the
actions, systems and policies that protect
humans from exposure to harmful biological
agents

4.  There are various components that together
contribute to bio safety
Broadly speaking to be a form of risk
reduction and control.
A risk control is anything that reduces the
ability of a hazard to cause injury to a person

5. Personal protective equipment
Laboratory physical containment systems
Decontamination techniques are well known
some Bio safety systems.

6. Principles of Bio safety
The term "containment" is used in describing safe
methods for managing infectious materials in the
laboratory environment.
The purpose of containment is to reduce or
eliminate exposure of laboratory workers, other
persons, and the outside environment to
potentially hazardous agents.

7. There are two types of containment: primary and
secondary.
 Primary containment is the protection of personnel and
the immediate laboratory environment from exposure
to infectious agents; it is provided by both good
microbiological technique and the use of appropriate
safety equipment.
 The use of vaccines may provide an increased level of
personal protection.

8. • Secondary containment is the protection of the
environment external to the laboratory from exposure
to infectious materials provided by a combination of
good facility design and suitable operational
practices.
• Therefore, the three elements of containment include
laboratory practice and technique, safety
equipment, and facility design.
