________
ENVIRONMENTAL RISK
ASSESSMENT

An environmental RISK assessment
(ERA) is a process for evaluating how
likely it is that the environment
(including human) may be impacted as
a result of EXPOSURE to one or more
environmental HAZARD, such as
chemicals, disease, invasive species,
and climate change.
(01) What is Environmental Risk
Assessment (ERA)?

An environmental RISK assessment
(ERA) is a process for evaluating how
likely it is that the environment
(including human) may be impacted as
a result of EXPOSURE to one or more
environmental HAZARD, such as
chemicals, disease, invasive species,
and climate change.
Assessment (ERA)?

EXPOSURE

*Potential for something to
cause harm.
*Includes substances,
machines, energy forms or
the way work is carried out.

cause harm.
• Air contaminants
• Toxic waste
• Radiation
• Disease-causing microorganisms and plants
• Pesticides
• Heavy metals
• Chemicals in consumer products
• Extreme temperatures
• Weather events
• The most common environmental health
hazards are air and water pollution.

*Refers to the time or
period and/or space or area
*Refers to the probability of
harm after exposure to
hazard during the work that
is being caried out or by the
way something is used

Source
Origin of the hazard
Pathway
Linkage that connects the
source of hazard and the
receptor
living organisms, habitat, or
natural resources which could be
adversely affected by
environmental contaminations

If there is no pathway, there is
no risk.
If the pathway exists, the
consequences must be
determined

(02) Elements/Steps of Environmental Risk Assessment

- the most critical step
- defining the scope of an
ERA by identifying what
needs to be protected from
harm
What are the problems?
➢ Too much solid waste
➢ Improper waste disposal
➢ Too much carbon dioxide emission
1 Problem Formulation
Elements/Steps of Environmental
Risk Assessment.

- examining the potential
environmental hazards
present in the workplace or
site
2
Risk Assessment.
What are the hazards?
➢ Too much solid waste that causes
pollution in water and soil
➢ Improper waste disposal leads to
other problems like flood that can
spread different kinds of diseases
➢ Too much carbon dioxide poses
threat to respiratory system and
causes acid rain.

- identifying what and who is
at risk
What type of exposure is present?
➢ long term exposure to carbon
dioxide is dangerous both human
and animals
➢ Garbage are spreading in the area
through clogged canals and people’s
lives are in danger
➢ Pollution affects the growth of
plants in the area.
3
Risk Assessment.

Is the situation risky?
➢ Is the situation low risk, medium risk
or high risk?
➢ Is the risk present acceptable, or
severe?
- combining hazard and
exposure characterization
results and then assessing
the risk
4
Risk Assessment.

What are the actions taken?
➢ What is the result of assessment?
➢ What are the precautions made
regarding the risk?
- recording the results of the
assessment and implementing
precautions
5
Risk Assessment.
Documentation

What’s the status of implementation?
➢ Is the precaution/solution being
maintained?
- reviewing the assessment at
regular intervals

Risk Assessment?
● Risk Assessment Table
● Job safety and Environment
Assessment (JSEA)
● Specific Risk Management Software
● Work Method Statement (WMS)
● Flowcharts, Checklists, Standards, etc.

In Risk Management process, the
results of the risk assessment are
integrated with other considerations,
such as economic or legal concerns, to
reach decisions regarding the need for
and practicability of implementing
various risk reduction activities.

RISK MANAGEMENT STRATEGIES
Terminate
Terminate the
source of risk
when possible
Mitigate
Mitigate the
effects by
improving
environmental
management
techniques or
engineering
systems
Transfer
Transfer the risk
through new
technology,
procedure or
investment
Exploit
Exploit the
potential benefit
of the risk by
embracing new
opportunities
Accept
Accept the risk
by not
intervening with
new or existing
situations

RISK MANAGER
An individual, a team, or an
organization with responsibility
for or authority to take action in
response to an identified risk.
RISK ASSESSOR
An individual or a team with the
training and expertise to conduct a
risk assessment.
ENVIRONMENTAL SCIENTIST
Scientists that generate data used in a
risk assessment – specialists in variety
of fields, including geology, hydrogeology,
chemistry, toxicology, and engineering
STAKEHOLDER
Any individual, team, or organization
interested in, responsible for, or
affected by the outcome of a risk
assessment.
(06) Environmental Risk Assessment &
Management – Key Players

What is the
Importance of
Environmental Risk
Assessment and
Management?

• Create awareness of hazards and risk.
• Identify who may be at risk (e.g., employees, cleaners,
visitors, contractors, the public, etc.).
• Determine whether a control program is required for a
particular hazard.
• Determine if existing control measures are adequate or if
more should be done.
• Prevent injuries or illnesses, especially when done at the
design or planning stage.
• Prioritize hazards and control measures.
• Meet legal requirements where applicable.
