It’s a new year, but the challenges in manufacturing remain the same: fewer available workers, globalization, innovation, safety and security concerns, and how best to use information.
As we enter 2018, we’ve compiled a list of 10 tips to help you meet these challenges and see immediate improvements in safety and productivity.
Improve Your Safety Maturity
We see safety maturity as a combination of culture (behavior), compliance (policies and procedures), and use of capital (technologies). Repeated studies show the top 20 percent of manufacturers achieve 5 to 7 percent higher OEE, 2 to 4 percent less unscheduled downtime and less than half the injury rate of average performers – and the top performers are extending their lead.
These best-in-class performers view safety as a key element in their pursuit of operational excellence. And they use contemporary safety methodologies to help achieve it. For example, an LNS Research survey found 75 percent of industrial companies said they have seen operational improvements resulting from the use of advanced safety technology.
So how do you join their ranks? Begin by assessing your own safety maturity and see how you compare to others. Understanding your performance level and areas for improvement is critical to optimizing safety.
Address Safety and Security Together
As industrial operations become more connected, organizations should review security risks in relation to safety risks. We all know security helps protect our intellectual property, operations and brand. Unfortunately, the inherent safety implications of security risks are too often overlooked.
By integrating safety and security programs and following key steps, you can assess, manage and mitigate the safety implications of security risks.
EHS is most directly responsible for worker safety but only directly controls the least-effective machinery-safety methods. Engineering focuses on technical standards yet has control of the most-effective machinery-safety methods. Often, these two departments view each other suspiciously, resulting in reduced safety and productivity.
A key element of safety maturity, mentioned above, is collaboration between the two – and with operations. In fact, a recent LNS Research study found that organizations in which these three functions collaborate experience a 15 percent lower median incident rate.
Perform Risk Assessments Early in the Design Process
Designing risks out of machinery, rather than building a machine and then trying to make it safer, is critical. Most companies perform a risk assessment at some point.
A key question for any new machine is when you will conduct a risk assessment on it. Is it early in the design process, when risks can be designed out? Or is it after the machine is designed, built, and ready to ship?
It’s vital to perform a risk assessment early in the design process and again after the machine is in place at its operating location to help verify compliance, safety, and productivity. Studies show that 60 to 70 percent of safety incidents occur outside of normal operating mode (during maintenance, repair, etc.). For more on the topic, please see this brief (PDF).
Design Ergonomic Machinery
Our industry’s changing workforce is creating new safety considerations. Younger and inexperienced workers are at higher risk for acute injuries. Older workers are at higher risk for musculoskeletal and repetitive stress injuries, which can often be chronic or career ending.
Getting the most from every available worker now requires building machines for a broader range of workers. This means including ambidextrous features and reducing repetitive motion, lifting and awkward placement of the body.
Use LOTO Alternative Measures to Improve Productivity
Safety doesn't have to come at the expense of productivity. Contemporary machinery design allows for minor service exceptions to lock-out/tag-out (LOTO) when procedures are routine, repetitive and integral to the use of the equipment.
When correctly used, alternative measures can improve productivity by reducing LOTO-related downtime while still maintaining compliance. In some cases, alternative measures can be the difference between mere compliance and operational excellence. Read more about using alternative protective measures (PDF).
Bring Safety into a Connected Enterprise
The power of the Industrial Internet of Things (IIoT) can substantially improve your safety compliance and performance.
A Connected Enterprise empowers safety professionals with a real-time understanding of worker behaviors, machinery compliance, causes of safety shutdowns or stoppages, and safety anomalies and trends. It can also help improve your ability to hire, train and retain employees. Read more about safety in The Connected Enterprise (PDF).
Make Safety Integral to Your Control System
Your control system should include safety-rated inputs, logic, and output devices to mitigate risks, improve productivity, and provide information to key stakeholders.
Designing effective, productivity-enhancing safety systems can be challenging. But safety design tools can streamline development and help confirm compliance.
For example, RASWin software can help manage and consistently document the safety life cycle. Safety Automation Builder software can help you design your safety system.
Safety function documents also can help you implement machinery safety functions and include safety-performance calculations, wiring, programming, verification and validation.
Use Smart Safety
New smart-safety designs and devices can reduce your wiring, design costs, and unscheduled downtime. For example, you can capture smart-device interactions to create predictive maintenance feedback and other information.
Controlling machine access to authorized and trained personnel to improve productivity, safety, and security.
Build Your Safety Expertise
You need engineers, system integrators, and machine builders with expertise in current safety standards, a proven track record in building safety systems, and knowledge of productivity-enhancing safety system design processes and technologies.
If you don’t have this expertise in-house, turn to your partners. Rockwell Automation employs nearly half of all TÜV Rheinland-certified safety professionals.
Our alliances include recognized system integrators and solution partners with safety expertise. These organizations have met stringent requirements, including a rigorous, months-long assessment and education process to become members of our PartnerNetwork program.
