If you are working on or
managing an Industrial Workplace, and you are interested in
keeping such process in production as long as possible, having insurance
support in case of eventualities, so, you are interested in applying FUNCTIONAL
SAFETY.
FUNCTIONAL SAFETY is the
methodology that leads the design, construction, and operation of an Industrial
Workplace, protecting people, equipment, and work environments from
harm.
Industrial Workplaces use
powerful machines and automated systems, which can expose operators to severe
safety risk.
To aim engineers who work
for:
·
Engineering companies in the design, selection,
installation, and commissioning of a (SIS) Safety Instrumented Systems
·
End-user’ companies who own and/or operate a process plant.
The course is not intended
for engineers involved in the design of internal hardware for logic solver
systems or for the design of field device components by OEMs.
The course is prepared to
provide participants with a view of the entire safety lifecycle from the user’s
point of view, as part of preparation for a (FS) Functional Safety engineer
certification.
1.
To understand the physical meaning of SIL rating.
2.
Review of IEC-61511 and IEC-61508 standard, applied in a
process plant.
3.
To understand SIL determination and SIL verification
processes
4.
Meaning and structure of a (SIF) Safety Instrumented
Functions.
5.
Verify if the design or implementation of a SIF satisfies a
required SIL rating.
6.
To understand and Review a SIL certificate.

What does functional safety help in improving?
Functional safety focuses on
those aspects that improve safety, detect faults and control failure — i.e.,
minimize uncertainty. Let us dig deeper to understand the two types of fault
coverage and the hardware element classification.
Who is responsible for functional safety?
The workplace or
project manager is the one responsible for ensuring that the project
reaches its goals. This includes all functional safety goals for any project to
which functional safety requirements apply. The project manager is authorized
to request resources from the organization.
What is an example of a functional safety concept?
For example: In
an airbag system, the safety goal is that "Airbags should only be deployed
during a collision more than 2g". In this example, the
sensing system to determine the impact of the collision should be responsible
for this safety goal.
What is the difference between safety and functional
safety?
Insulation to protect the
system against high temperatures is a safety measure but not a functional
safety measure. Both may prevent fire. Now let us work through a further
example in more detail. Functional safety inherently means the safe
operation of a product during its primary function.
What are safety goals and objectives?
The goals and objectives
should focus
on specific actions to improve workplace safety and health. To
establish goals, management should: Establish realistic goals for improving
safety and health. Goals emphasizing injury and illness prevention should be
included rather than focusing on injury and illness rates.
