Safety: An ounce of prevention is worth……a life!

As Junes comes to a close we are reminded that it is National Safety Month . As we get bombarded with daily reminders to wear sunscreen by the pool and cheesy posters with cheesier sayings, keep in mind the meaning behind them is vitally important. As an active participant on our company’s safety committee, it can be easy to turn a safety project into a long term, high investment project that will be as safe as possible. But it can often come at the expense of a simpler solution that can start making your front line worker safer NOW rather than tomorrow.

As safety professionals, advisors, or just leaders of people, we are responsible for those that are exposed to hazards on the front lines doing the work. It is our responsibility to make sure that we find sensing solutions that not only protect, but can be implemented quickly and easily to ensure protection now.

But here lies the dichotomy; whatever the sensing solution is, it can’t be cheap and create the chance to supply false security.

These issues create contradictions. We need inexpensive but not cheap, sophisticated but not complicated, fast and easy to install but not to cause any adverse effect in the production environment. We attempt to optimize current solutions by multiple factors and the result is typically a well-balanced, mediocre, piece of junk. When real safety problems occur, we need step changes in technology that take away the balancing act of specs and open up new ways to keep people safe.

Enter wireless communication. We have been proving in use with our dependence on cellular phones for over a decade with increasing reliability. We are replacing wired home phone lines with cellphones, airplane boarding passes with e-tickets on our cellphones, and even doing our banking over our cellphones. Industrial wireless communications are more robust and reliable than they have ever been and are ready for the mainstream of industrial market sensing applications.

The cost savings of wireless are readily apparent: less wiring, less money. What is sometimes lost is the ease and speed of installation. This is where wireless can offer a step change in safety. Need additional points to monitor, no problem. Need to move a point to a more ideal location, no problem. It is now easier and faster than ever to get monitoring installed that will start to protect your people now.

As a vendor, allowing the limitations of old technology and “it’s always been done this way” to become excuses against creating better ways to bring value to the customers will be detrimental as new technology and services emerge. It’s on us to not only adapt new technology but to embrace it as the path forward. Further we must be instrumental in creating the data to prove performance and reliability.

So as we wrap up  June and make jokes about the cliché posters, remember to look to find innovative solutions that will help to you protect your people now. Accidents won’t wait for you, so why wait on implementing safety? Start searching for solutions that will help you keep your people safer NOW.

The One Series Safety Transmitter for Increased Plant Safety

united electric safety transmitter

The power generation market is beginning to emphasize the importance of plant safety. This was made clear to all attendees during the keynote session at the Power-Gen International Show in Orlando held in early December. Ms. Kimberly S. Greene, executive VP and COO of Atlanta-based power generation Southern Company made a passionate plea for better safety standards within plants that fall under the Southern Company umbrella, and to begin thinking about plant safety and investing in safety automation technology to provide some solutions. According to Ms. Greene, Southern Company facilities sent 300 workers home with workplace injuries in 2014.

In one case this year, a 44-year employee died on the job, causing Ms. Greene to make an emotional plea to all attendees and plant managers to move safety to the top of their priority lists. For the power generation market, plant safety has not (yet) received the same level of attention when compared to the hydrocarbon processing market. Ms. Greene’s statistics reminded us all that functional safety must be considered across many industries that include harsh and hazardous operating conditions and processes.

The One Series Safety Transmitter is a pressure and temperature monitoring transmitter-switch that provides a NAMUR NE 43 standard 4-20 mA analog output. Its programmable high-capacity solid-state safety relay output enables the fastest emergency shutdowns in the industry.

The One Series Safety Transmitter was designed with features that simplify installation, improve productivity, and eliminate nuisance trips. The instrument is password protected to prevent unwanted parameter changes; eliminating the risk of tampering. The large backlit digital display provides process variable, status, self-diagnostics and field programming information.

Some of the advantages of using UE’s safety transmitter are:

  • ​4-20 mA analog output with field scaling capability
  • ​100% programmable high-capacity safety relay for switch mode, set point & deadband
  • ​Effectively replaces a gauge, transmitter, and a switch to reduce potential leak paths
  • ​Additional discrete outputs to facilitate voting logic schemes
  • ​The industries highest safe failure fraction (SFF) of 98.8% as certified for use in SIL 2 by exida

Replacing Mechanical Switches in a Safety Application

Is it that time to upgrade your plant’s safety instrumentation? If your case is the typical upgrade move from mechanical switches to a transmitter, do you know specifically which type of transmitter you should be getting? What is the best means of replacing mechanical switches in a safety application?

united electric safety transmitterIt’s often necessary to replace mechanical switches because they are considered blind devices; they cannot warn you when they have become faulty, nor can they be relied on completely, as they have many moving parts. This can result in the sensor cracking, the piston sticking, or the micro-switch wearing out. Unless the switch is tested on a regular basis, there is no way to determine when problems exist. This is the main reason many facilities are moving towards transmitter upgrades.

Typical transmitters, however, can be very costly for a plant. Not only is the instrument itself expensive, but there are many hidden costs as well. A transmitter will require major input to the control system, including analog requirements, cabling, and the reprogramming of the control system to accommodate the updated continuous signals that process pressure changes. With all of this, the programming tasks become increased.

By now, you should realize that United Electric Controls places safety and quality above all else. So what would we recommend using instead? Our One Series Safety Transmitter. Since the One Series Transmitter contains a built-in switch function and has a self-diagnostic feature, programming would remain the same in the upgrade process. This way, you are saving money and time in the upgrade process without compromising an ounce of safety.united electric safety transmitter 2

We designed the One Series Safety Transmitter from the ground up with the intent to use it specifically in safety applications. In comparison, other transmitters are meant for process applications, meaning accuracy is high but not necessarily functional for safety situations. When it comes to safety, high quality, designed safety transmitters are the best option to go with.

Safety Comes First with our Newest Transmitter

What’s one thing that all plant and facility managers can agree on? Safety comes first. This is precisely why we have made safety the number one feature of our new One Series Safety Transmitter.

One Series Safety TransmitterSpecifically, we are referring to the safety relay feature of the transmitter, which sets the transmitter apart from other products of its kind. It is an internal, programmable, solid-state relay that is used to initiate emergency shutdown directly from the instrument, as opposed to having to operate indirectly through a PLC and DCS, as is the case with other instruments.

Typical safety systems consist of a sensor (which is the safety transmitter), a logic solver (a PLC or DCS), and a final element (an electrically-actuated valve). Other safety transmitters must operate through the PLC to initiate an emergency shutdown, requiring up to 800 milliseconds to respond. With the One Series Safety Transmitter, the sensor and logic solver functions are combined into one instrument. By eliminating the need for a separate logic solver, our safety transmitter initiates the emergency shutdown directly and within 100 milliseconds.

Chemical processing plants are particularly hazardous environments. If a dangerous chemical reaction occurs, it is necessary that certain safety functions are in place to protect the plant and plant employees. When it comes to safety, time is of the essence—meaning there is a huge difference between an 800 millisecond reaction and a 100 millisecond reaction. With UE’s One Series Safety Transmitter, the response time is reduced dramatically due to the elimination of the PLC or DCS. By simplifying the SIF, the safety integrity level target is more easily achieved in a shorter period of time.

At United Electric Controls, we understand that safety should always come first. The One Series Safety Transmitter provides the industry’s highest safe failure fraction and integral safety relay output for minimum response time and maximum SIF design flexibility.
