Hazard
DISASTER READINESS AND RISK REDUCTION MANAGEMENT
Hazards are potentially
damaging physical events,
phenomena or human activities
that may cause injury or loss of
life, damage to property, social
and economic disruption, or
environmental degradation
(UNISDR 2007).

Biological Hazard
3
Also known as biohazards, refer to biological substances that
pose a threat to the health of living organisms, primarily that
of humans. This can include samples of a microorganism,
virus or toxin (from a biological source) that can affect human
health.

Astronomical Hazard
4
A potentially hazardous object (PHO) is a near-Earth object –
either an asteroid or a comet – with an orbit that can make
exceptionally close approaches to the Earth and large
enough to cause significant regional damage in the event of
impact.

carelessness, or inability to
implement protective measures.

High-risk recreation hazards
3
Outdoor recreation, such as hiking, camping,
canoeing, cycling, or skiing, entails risks, even if
participants do not recklessly place themselves in
harm's way. In some circumstances, such as being in
remote locations or in extreme weather conditions, even
a minor accident may create a dangerous situation that
requires survival skills.

Hazard Analysis
It is the identification,
study, and monitoring of
any hazard to determine
its potential, origin,
characteristics, and
behavior. – UNISDR 2007.
