3. Biological risks
In our surroundings a variety of microbes
like bacteria, viruses, fungi, protozoans, etc.
are present. These microbes cause various
diseases to human beings. Similarly, different
types of vectors like mosquito, sandfly,
honesty, etc. transmit various diseases to
human beings. Different types miorobes and
vectors increase the risk of diseases among
workers in work place. A variety of diseases
may occur to the farmers working in field, Fig: 17
poultry farms, etc. There is risk of getting infection with birdflu to the people working in
poultry farms. Similarly, there is risk of getting swine flue to the people working in pig
farms. Therefore, precautions and safety measures should be adopted to avoid biological
risks.

4. Mechanical risks
We should work with a variety of machines
in factories and industries. The workers may
get injures while working with machines.
There is risk of getting injury while operating
different types of machines. Many workers
lose their body parts or even life in factories
and industries while working with machines.
Therefore, the workers would be very careful
and sensitive while working with machines.
They should adopt safety measures to avoid Fig: 18
mechanical work in their work places.

Management of natural hazards
Various natural factors are responsible for occurring natural hazards. Thus, human beings
cannot stop natural disasters from occurring. But, there is the possibility of minimizing
the damage and loss that may occur by natural disaster. Therefore, it is necessary to
design plan for management of natural disasters by identifying their types of causes of
their occurrence. Adoption of the following activities may be helpful in the management
of natural hazards.
i. Generating public awareness to stay alert to natural disasters.

ii. Conducting immediate rescue activities for the disaster affected people.
iii. Managing physical and financial support for affected people.
iv. Mobilization of various welfare organizations to provide support to the affected
people.
