Most people use the common approach!
5
Most people only analyze automatic operations! Fact – 60 to 70% of all injuries occur outside of normal production activities.
Most people identify hazards and immediately select safety devices/solution without considering the effects on productivity! The number 1 cause of safety system failures is because the solution is
bypassed. This happens because it was not designed to accommodate job tasks.
Most safety systems that follow the common process result in significant reductions in equipment utilization!
Most people have never been to a training session or have never read a machinery safety standard! This results in safety systems that are inadequate, ineffective & improperly designed.
Copyright © 2013 Rockwell Automation, Inc. All Rights Reserved.
The Proper Approach: A standards based methodology!
6
Both EN, ISO and ANSI standards require a systematic approach for safety system development! The first step is the risk assessment.

Development Considerations!
• What machine/machines are to be guarded?• What are the characteristics and limits of
the machine/machines?• What are the different modes of operation
of the machine/machines?• Who interacts with these machines during
normal and abnormal operation?• What are those people doing?• How does the machine need to function in
each mode of operation?• Are these any special system needs?• What type of diagnostics is needed?• What type of system performance is
needed?• What is the target efficiency rate of the
machine/machines?• What is the company specification?• What can be done to improve safety and
productivity?
What do I need to consider?

1. Assessment
The Machinery Safety Lifecycle is a defined process that is followed to ensure that proper safety practices have been implemented!
5. Operate, Maintain & Improve
4. Installation & Validation 2. Functional
Requirements
3. Selection, Design & Verification
Copyright © 2013 Rockwell Automation, Inc. All Rights Reserved.
Rockwell Automation follows the safety lifecycle to evaluate machinery safety solutions because:
• It remove uncertainty and eliminates omissions and errors!• It provide a repeatable process that leads to complete safety
solutions.
An idea without a plan leads to indecision, omissions and mistakes!

Step 2 in the Machinery Safety Lifecycle is the safety requirements specification!
The SRS defines the functional requirements of the safety system!
Copyright © 2013 Rockwell Automation, Inc. All Rights Reserved.
The main reason for developing a functional spec!
The SRS defines my solution!
• It identifies how the machine is to operate in each mode of operation for each person that interacts with the machine!
• It identified special needs like: (Safe-speed/Safe-direction/Zone control/Etc.)
• It also identifies any special diagnostics and interface needs!

Step 3 is the selection, design & design verification phase.
This step focuses on safety system design, product selection, circuit selection and design verification!
Copyright © 2013 Rockwell Automation, Inc. All Rights Reserved.
My assessment & requirements spec sure made this easy!
The design phase includes selection of mitigation techniques, products, circuit designs & system structure determination!
Design considerations:• What mitigation technique should I use?• What circuit structure should I use?• What safety products should I use?• What type of control system should I use?
(Relays/Controllers/PLC’s)• What type of special operations do I need?
(Zone control/Safe-speed/etc.)• Where are all of my safety devices?• What kind of interactions are needed for
auxiliary machines?• What kind of diagnostics do I need?• Should I use hardwiring or networked
systems?

• There should be specific instructions regarding safety product installation and wiring!
• There should be specific instructions regarding wiring methods and grounding!
• There should be specific instructions regarding panel fabrication and wiring!
• There should be specific instructions regarding signage installation and location!
• There should be specific layout drawings showing a routing, mounting and installation instructions!
• There should be specific electrical schematics regarding terminations & connections.
Copyright © 2013 Rockwell Automation, Inc. All Rights Reserved.
How do I validate my safety system?
• Verification & Validation considerations:• There should be specific instructions
regarding the verification of each safety function!• This means that each safety input, logic
& output device must be tested to ensure it functions as intended!
• This means that each combined function of input/logic/output must be tested to ensure that it functions as intended!
• This means that each programmed function is verified to ensure it functions as intended!
• There should also be specific instructions regarding validation-fault injection to test the safety system!• Common testing methods include:
• Shorting wires, breaking connections, removing wires, etc.

How do I operate my machine?
Step 5 – Operate, Maintain & Improve
• The should be training for all personnel that will be interacting with the machine.
• The training should include:• Intended use• Safety system components training• Normal operations• Abnormal operation• Safety system functionality
Copyright © 2013 Rockwell Automation, Inc. All Rights Reserved.
How do I maintain my safety system?
Step 5 – Operate, Maintain & Improve
• The standards say that periodic testing should be done to verify proper system functionality. (There is no defined period or timeline that is suggested)
• The standards also require additional assessments after machine modifications. This might include:• Program changes• Speed changes• Hardware changes• Machinery changes• System modifications

The Safety Process – What do I do?
63
Ok, I need to make my machine safe. Now what? Four Questions To Navigate the Jungle
What do I need to do? What are my options? How much do they cost? Which option is right for me?
Let’s Look At A Couple Of Options…
Copyright © 2013 Rockwell Automation, Inc. All Rights Reserved.
Let’s look at a sample machine!
64
We are going to use the safety tools to develop a safety solution utilizing Safety Automation Builder. This will leave us with a concept drawing, a design verification and a complete bill of material.
We will use the ROI tool to help the customer justify the project. We will then search for solutions for the selected products using safety
functions, safety accelerator toolkit and connected components building blocks.

Identify the hazards and associated risks! Develop a functional specification that outlines how each hazard needs to be protected for each mode of operation.
Thermal Hazard
Crushing Hazard
Pinching Hazard
Pinching Hazard
It is estimated that 60 to 70% of all injuries happen outside of normal production activities yet most people spend 90% of their efforts around designing for production activities!
Copyright © 2013 Rockwell Automation, Inc. All Rights Reserved. 68
Show how the ISO12100 risk methodology is used to determine the required system performance that is to be implemented.
Step 2 – Functional Specification Development
Copyright © 2013 Rockwell Automation, Inc. All Rights Reserved.
Step 2: Write a Functional Specification
69
The assessment defined the task and associated hazards and the required system performance that is required.
The function specification will determine the required safety functions, their design requirements and the type of functionality that is needed for each mode of operation for each person that interacts with the machine.
