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 © 2014 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!
So which standard is right for you?

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?

The Rockwell Automation Approach Follows the “Safety Life Cycle”
9
1. Assessment
The Machinery Safety Life cycle 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 © 2014 Rockwell Automation, Inc. All Rights Reserved.
Rockwell Automation follows the safety life cycle to
evaluate machinery safety solutions because:
• It removes 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!

5. Operate, Maintain & Improve
1. Assessment
4. Installation & Validation
2. Functional Requirements
3. Selection, Design & Verification
Step 2 in the Machinery Safety Lifecycle is the
Safety Requirements Specification!
The SRS defines the functional requirements of the safety system!
Copyright © 2014 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!

3. Selection, Design & Verification
Step 3 is the Selection, Design &
Design Verification Phase.
This step focuses on safety system design, product selection, circuit selection and design verification!
Copyright © 2014 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?

How do I install my safety system?
Step 4 - Installation
• Installation considerations: • There should be specific instructions
regarding physical barrier installation! • 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 © 2014 Rockwell Automation, Inc. All Rights Reserved.
How do I validate my safety system?
• Validation considerations: • There should be specific instructions
regarding the validation of for 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 validated to ensure it functions as intended!
• There should also be specific instructions regarding fault injection to test the safety ! • 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 • Safety system operations
Copyright © 2014 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 • Safety system use • Hardware changes • Machinery changes • System modifications

Step 1: Details
70
Normal operation
Maintenance
Set-up
Adjustment
Change-over
Start-up
Decommissioning
Etc.
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!

Show how the ISO12100 risk methodology is
used to determine the required system
performance that is to be implemented.

Step 2: Write a Functional Specification
72
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.

Define Our Safety Functions
When Door Opens in zone #1, tray packing stops, zone #2, tray forming continues.
Safety Function: Safety related stop function
initiated by a safe guard
Stopping hazardous movement
Triggering Event: Opening of guard door
Zone #1 Zone #2
Follow this Process for Every Safety Function in Every Machine Mode!

Now we Have a Price! We Need to Justify the Investment!
81
We will use the Safety Return on Investment Tool to justify the project
based on projected reductions of injuries and productivity enhancements!
Let’s calculate our savings and ROI for this machine example!
