Whether it’s because of the materials, equipment, or tasks involved, most industrial processes carry some element of risk. To minimize the likelihood of accidents and disruptions on the job, process managers must anticipate these risks and implement appropriate preventative strategies where necessary.
As demand for productivity spikes across American industry, workplace safety has become more crucial than ever. In turn, its heightened importance has led to a greater need for equipment and instrumentation that can provide reliable measurements of safety strategies process parameters.
At Endress+Hauser, safety is at the forefront of our business. Indeed, a deep commitment to the health and welfare of the workforce lies at heart of all of our products. With National Safety Month well under way, we wanted to take a moment to share our approach with you.
Functional Safety SIL
Endress+Hauser works to establish functional safety in industrial systems and processes. The International Electrotechnical Commission (IEC) defines functional safety in the IEC 61508 standard as “part of the overall safety that depends on a system or equipment operating correctly in response to its inputs.” It combines elements of quality, reliability, and systems engineering to implement risk management measures, mainly in electrical and electronic systems.
Assessment of risk-management and risk reduction strategies involves a type of quantitative safety evaluation called a safety integrity level (SIL). The SIL is essentially a measure of the performance of a particular safety function. IEC 61508 defines four SIL levels, with SIL 4 providing the highest level of safety performance.
SIL levels depend on the desired safety performance of the system. They are determined using a criteria matrix that consists of several factors, including the extent of loss, time of exposure of persons in the hazardous zone, the possibility of hazard control, and the incidence rate.
True functional safety entails an end-to-end scope, with each component or subsystem treated as parts of a single system rather than individual items. Most safety systems include several components: a control system, an actuator, and a measuring instrument. To ensure functional safety throughout the system, all functions and components must meet the necessary safety level.
National Safety Month
Guided by this comprehensive approach to workplace safety, Endress+Hauser proudly supports National Safety Month. Celebrated every June by the National Safety Council (NSC), National Safety Month aims to spread awareness of leading causes of injury and death at work, on the road, and in our homes.
Over the course of the month, the NSC will release public materials each week that highlight a different safety topic for users to download and share. The safety topics highlighted this year are:
- Week 1: Emergency Preparedness
- Week 2: Wellness
- Week 3: Falls
- Week 4: Driving
Endress+Hauser understands that true functional safety isn’t possible without safety instrumented systems that feature the best SIL-certified equipment. To that end, we offer an extensive portfolio of safety-oriented equipment that is unmatched in the industry. Our IEC 61511/61508 compliant instrumentation is designed and manufactured based on decades of experience and a strong conviction that productivity depends on safety.
From preliminary conceptual designs to the finished product, Endress+Hauser prioritizes safety at every stage of operations, ensuring high mechanical integrity in all of our products. If you’d like to learn more about our solutions and services, contact us today.
