Hazard and Effects Management Program

• The HEMP is at the heart of our HSE
Management Systems. It’s where the planning
turns into action.
• HSE Risk Management relies primarily on
HEMP and it’s associated tools.

4. What is a HEMP?
• All our activities have the potential to harm people and the environment or
cause damage to assets, financial loss, and to adversely impact on reputation.
• To manage these risks, we use a Hazard and Effects Management Process
(HEMP)
• A HEMP is a structured approach to identifying and managing the hazards and
potential effects of these activities.
• The overall objective is to reduce risks to As Low As Reasonably Practicable
(ALARP).
• A HEMP evaluation can be detailed e.g. an HSE Case for a high-risk activity such
as Road Transport
• ... or a relatively short e.g. For a single task in a mechanical workshop such as
changing a tyre.

HAZARD - An agent that has the potential to cause harm to People, damage to
Assets, business loss and Impact on the Environment or Reputation
Hazards are systematically identified using a standard hazard checklist

Chemicals
Step1
Hazard Identification

8. 1. The potential to harm people or the
environment, cause damage to or loss of
assets, or adversely impact reputation.
2. Consider the hazards arising during the
entire lifecycle of an asset or activity;
• Planning, mobilisation & set-up
• Routine conditions
• Abnormal conditions (e.g. weather
extremes & use of back-ups)
• Reasonably foreseeable incidents
and/or emergency situations
• Demobilisation
• Past activities
As a start, consider these hazards:
• Flammable and explosive
substances
• Chemicals and toxic substances
• Land Transport
• Working at heights above 2m
• Confined spaces
• Slips, trips and falls
• Machinery with moving parts
• Extreme temperatures
• Electricity
• Objects under induced stress
• Lifting and moving equipment
• Security

10. 2 – ASSESS the Risk
Use the Matrix to:
• Assess the risks of the
identified hazards by
assessing the
likelihood of the effect
occurring and its
consequence.
• Categorise each risk as
Low, Medium, or High.
10

11. 2 – ASSESS the
Risk

12. • Risk is the likelihood that a specific consequence
will occur within a specified period
• Risk is therefore a function of the severity of a
consequence and the likelihood of the consequence
• In using the PDO RAM, we consider the worst
credible consequence to People, Assets,
Environment and Reputation
• Likelihood is HISTORICAL (has it happened before in
The location? The organisation? The industry?)
• Risk rating (ranking) is the resulting position on the
RAM
RISK = Consequences X Likelihood

13. 3- CONTROL the risk
• Following assessment of risks,
HEMP requires that controls
be applied in order to reduce
risks to ALARP.
• Controls should focus on risk
elimination and reduction
before recovery measures.
• Controls should include
preventative and mitigation
measures involving active,
passive and/or operational
systems.
• Examples of operational
systems to be considered
include:
• Training programs
• Monitoring programs
• Procedures & work
instructions
• Management plans
• Emergency response plans
• Audit and inspection
programs.
13

14. 4 – Is the Risk ‘ALARP’?
“As low as reasonably practicable”.
Risks are ALARP when the time,
effort, difficulty and cost of further
risk reduction measures have been
assessed as being unreasonable in
regard to the additional risk
reduction.
ALARP has NOT been achieved if, a
small increase in cost and effort,
could greatly reduce a risk.

15. 5 – RECOVERING if the controls fail
Once the controls required to
reduce the risk to ALARP have
been identified, an additional
examination of the hazard
control measures should be made
This will to identify how
recovery from a hazard can be
accomplished if all of the controls
fail.
Note they will be recorded as
another control
• Physical equipment (e.g. roll-
bars, seat belts, airbags).
• Action plans for emergency
response (e.g. call-out duty
roster).
• Curative measures (e.g. medical
facilities, first aid training).
• Compensative measures (e.g.
financial payments).

Identification of Barriers (the Control and Recovery Measures)
• CONTROLS prevent the threat from releasing the hazard to cause the Top
Event.
• RECOVERY MEASURES mitigate the Top Event or the worst credible
consequences.

18. 6 – RECORD6 – RECORD
• The final step of HEMP is formally
recording the process.
• This is typically done by recording the
findings in a HEMP Register
• Please note this is a live document.
• It must be reviewed and changed
regularly
• It must be used onsite by the people
planning the jobs
A HEMP register should include:
• A description of the hazard.
• Probable threats
• Possible consequences
• Escalation factors increasing
the likelihood or severity of an
incident.
• asks undertaken to provide or
maintain controls or recovery
measures (HSE-Critical Tasks).
• Positions responsible for HSE-
Critical Tasks (HSE-Critical
Positions).

Exercise
1. Imagine you are the owner
of the Nairobi Zoo, and you
have the opportunity to
acquire a lion for your zoo.
2. Up until now you have only
had sheep and rabbits in
your zoo.
3. Identify the Hazard, Top
event and Consequence,
RAM your Consequence
4. What can go wrong and
how can you prevent this
from happening?
5. What happens if the Lion
Gets out? What do you do?
