Safety risk

Safety risk management is a generic term that
encompasses the assessment and mitigation of the
safety risks of the consequences of hazards that
threaten the capabilities of an organization, to a level
as low as reasonably practicable (ALARP).

RISK
A hazard is actually a source of risk
The definition of a risk from a safety perspective is that a risk is equal to
the hazard times the exposure.
Here’s an example: working at heights is a hazard, but that’s not the risk. There are a
couple of risks that come from that hazard working at heights. First and foremost, a
worker can fall from heights and you can actually determine what controls you have in
place, and the effectiveness of those controls when determining the likelihood of the risk
occurring.
‘We could have a second risk from that which is that a worker drops equipment or tools
ight.

Incident & Event
If an incident occurs, it means that something is already wrong.
An event is a slight change in the state of the system. If an
event occurs, it is an indication of a possible system failure
occurring in the future.

Hazard Identification
Hazard identification focuses on conditions or objects
that could cause or contribute to the unsafe operation
OR safety-related equipment, products and services.
A hazard may involve any situation or condition that has
the potential to cause adverse consequences.
The scope for hazards in PDC is wide.

Hazard identification and
prioritization
Hazards exist at all levels in the organization and are detectable
through many sources including reporting systems, inspections,
audits, brainstorming sessions and expert judgement.

The following should be considered when
identifying hazards
» system description
» design factors, including equipment and task design; human
performance limitations (e.g. physiological, psychological,
physical and cognitive); procedures and operating practices,
including documentation and checklists.

Some Hazard Identification and
Analysis Tools
> Observation and reporting
Anyone working at company or using company facilities
should be able to report hazards that they see. The
process can be more effective when company staff has
received training on how to identify and report hazards,
a_system or tool is available for reporting, li

Some Hazard Identification and
Analysis Tools
» Daily Inspection
Daily inspections are effective in identifying safety
hazards. The procedure can be more effective if
inspectors have received training to identify types of
hazards.
صفحه 34:
Some Hazard Identification and
Analysis Tools
» Functional brainstorming
It consists of gathering a group of people to discuss
the issue and identify hazards. A facilitator will
make the process more effective.
صفحه 35:
@) Some Hazard Identification and
Analysis Tools
» Accident and incident investigation
A thorough investigation can discover the causes and
contributing factors, particularly those hazards that
are not obvious (for example deficient training), and
investigation reports can communicate the identified
hazards to company decision makers for SRM action.
صفحه 36:
Some Hazard Identification and
Analysis Tools
> Audits
Safety and SMS audits are effective tools to identify
hazards that are not obvious. Hidden hazards can
include outdated training, organizational issues,
deficient operational processes and procedures.

1. Identify the Best Treatments
Determining the most appropriate risk management
solution(s) involves balancing the potential benefits
of a treatment plan against organizational
objectives, costs, efforts and available resources.

treatments are possible, they are not necessarily

3. Prepare and Implement Risk Treatment
After completing the review of potential controls and their expected
impact, it’s not enough to select a risk treatment option and leave it at
that. You have to properly implement and maintain it to achieve optimal
effectiveness.
The plan should be integrated into existing management systems and
processes (e.g., maintenance planning, operating procedures) to make the
implementation as seamless as possible. Managing risk should be
