4. Hazard
A situation that poses a level of threat to life,
health ,property, and environment. (Nebel &
Wright,1993)
Most hazards are dormant, armed, active.
(Wikipedia 2010)
Risk= hazard x vulnerability (– )capacity
The likelihood or probability of an adverse
outcome or event.

7. Chemical Hazards
Harmful chemicals in the air water,food ,or soil
‘ Toxic’: causes temporary or permanent harm or
death
‘ Hazardous’: causes harm because it is
flammable,explosive, or irritates
skin,lungs,causes allergies.
Mutagens: causes a mutation in DNA ; increases
change for mistakes in the DNA to occur
Teratogens: harms,causes birth defects in fetus
or embryo
Carcinogens- promotes cancer

8. Biological Hazards
Pathogens, bacteria, viruses, parasites, etc.
Non-transmissible disease: does not spread from
person to person .Ex. Ashma, cardiovascular
problems, and malnutrition
Transmissible disease: also known as
“infectious” a disease that can spread from
person to person

9. Physical Hazards
Fire, earthquakes, tsunami,
volcanic eruptions, floods,
typhoons, etc.

10. Physical Hazards

11. GEOHAZARDS
• are geological phenomena that pose
danger to people’s lives, properties,
infrastructure and communities. These
include landslides, flooding and land
subsidence. However, in some cases,
geohazards can also be induced by
human activities.
• Geohazards cannot be totally prevented
but their impact on people and the
environment may be lessened or
mitigated. (www.denr.gov.ph)

12. GEOHAZARD MAPPING AND
ASSESSMENT

13. Causes of Hazards
• Natural Hazards
• Man-made Hazards
• Deadly force or retribution

14. Risk Assessment
Scientific process of
estimating the harm or danger
a particular hazard can have
on human health or
environment
Identify it!
Probability?
Consequence?

15. Development of Plans
• How to assess
unknown
hazards
• What do you
already know
about these
drums?

16. Possible Scenarios
• As an
emergency
responder,
unique
exposures are
possible

17. Risk Management
Making decisions to
reduce the risk of a
potential hazard.
Analyze: Is it worth it?
How much reduction?

18. Flammable Hazards
• Watch for
Flammable
Hazards

19. Let’s ponder on this…
