Over the past 10 years machine safety has experienced probably the greatest transformation since the advent of machine control technology.

It was in the early 1970’s that machine safety was mandated by industry standards to be “hard wired.” At this time, PLC technology had just been introduced, and its reliability paled in contrast to the robust PLC reliability of today.

These can diminish the effectiveness of training, regardless of the sophistication of the simulators employed.

Intelligent valve technology and partial stroke testing

Smart valves can simplify deployment of safety systems and provide a higher level of plant protection through more effective testing. Safety instrumented systems (SISs) have become essential components of today’s new process plants. This advance has been driven by a variety of forces, from new industry standards to increased pressure from governmental agencies worldwide and lessons learned following high-profile accidents. Partial stroke tests (PSTs) of emergency shutdown (ESD) valves have long been used to improve SIS performance. By monitoring these critical valves regularly, PSTs help ensure the system’s ability to shut a process down in the event of an emergency. See more charts and graphs.

Product Safety Certificates – Like SIL – What’s Their Purpose?

In the news recently there’s been some buzz about the product safety certificates around questions like:     1.)   Are these safety certificates required by insurance companies?     2.)   Are these safety certificates required by industry standards?     3.)   Are these safety certificates required by local codes or regulations?     4.)   And,…….the list goes on? This blog is a call for comment from anyone who has an opinion. Some of us might recall that when hardware and software based products were first made available for safety applications they had to be designed, built, and tested to a standard. The first standard that I’m aware of for industry for this purpose was IEC 61508-1 and it required that these products be tested and listed for such use.

Flowmeters eliminate cleaning

Shell Chemicals, at Moerdijk, the Netherlands, operates one of Europe's largest ethylene plants, where Emerson's Vortex 8800CD dual-vortex flowmeters improved plant steam-measurement reliability. The meters provided two flow measurements on the main steam lines: one for plant process control and a separate measurement for the plant safety instrumented system. Shell found that vortex metering delivered more reliable steam-flow measurement, increasing plant uptime. Furthermore, plant operators have a better, more accurate steam-flow measurement, allowing production optimization. Shell's naphtha-cracker process mixes accurate proportions of light distillate feed-stock (LDF)—such as naphtha or ethane—and steam, heating them to a high temperature in a furnace, cracking the LDF into basic feedstocks like ethylene, and also creating some carbon and coke deposits, that recirculate with process water. To remove these deposits and assure measurement reliability, a monthly cleaning schedule had been established for each flowmeter. Engineers conducted a three-month trial with a Rosemount 8800CD on one furnace line.

Its advantage over other technologies, STI says, is “versatility and non-intrusive presence.” Unlike hard guards such as fences or safety floor mats, the laser scanner works without physical barriers so is perfect for equipment that requires regular maintenance and cleaning. “Fewer hardguards are needed, allowing sweepers, forklifts, and loaders to transit through its protection area.” STI explains that “Safety laser scanners function by using a‘time of flight’ measurement to determine distance.

Safety PLCs

When is a PLC a safety PLC? Generally, a safety PLC is a programmable logic controller designed for use in mission-critical or safety-related applications; if a safety PLC fails, it does so without endangering people or processes. Actually, "safety PLC" is a bit of a misnomer. Even if a PLC achieves a specific safety integrity level (SIL) rating, it still can be applied in an unsafe way.

In fact, some production areas can be downright hazardous. Petrochem plants, underground mines, even grain silos pose the potential of accidental explosion, due to ignitable gases, vapors, or dust that may be present. Various classification systems have been set up to identify these potentially dangerous industrial environments so that electrical equipment operating in those areas can be regulated to prevent ignition and explosion, thereby ensuring the safety of workers and facilities.

Intrinsic safety—fieldbus style

Devices and barriers for intrinsically safe areas are designed so the energy released by an electrical fault is insufficient to cause ignition, even in a single- or double-fault condition. The ignition point is a function of available power-voltage and electrical current. How much segment electrical current, voltage, barrier choices, and devices permitted per barrier depends on the type of hazardous atmosphere in which the devices are located, and which intrinsic safety model is used.

When enacted, the bill will govern security operations at 15,000 industrial chemical sites, down from the 40,000 plants and refineries included in an earlier version of the bill. The approved bill also dropped proposed regulations governing the transportation of hazardous chemicals, and softened a section that would have imposed strong criminal penalties on site managers that failed to meet security standards.

One responder at a big-name company was struggling to find a way for maintenance technicians to determine if a PC's (personal computer) motion control card was bad, the drivers were corrupted, important DLL files had been accidentally deleted or modified, another application was hogging the interrupts, or some other PC-related problem existed.

Rosemount Analytical links safety with process analyzers

I n the past, many analytical analyzers were so temperamental that users often refused to allow them to be directly connected into the control system. Instead, control systems would interface with the analyzer through an operator who would observe the readings and 'tweek' the control system accordingly. In order to ensure system safety when their analyzer is part of the control system, Rosemount Analytical (Orrville, O.) has developed and obtained a control safety patent for its Raman Process Analyzer and other optical analyzers. The Raman Process Analyzer uses the Rayleigh backscatter principle to provide reliable laser cessation for increased safety.

T he performance-based standards ANSI/ISA S84.01, IEC 61508, and IEC d61511 mandate the use of risk assessment techniques to meet the established target risk level(s) for a process. Different risk assessment techniques that are quantitative, qualitative or semi-quantitative in approach are used to evaluate the process risk and identify the safety systems needed to meet the target risk levels. Such an analysis of process safety requirements is called Safety Integrity Level (SIL) analysis. Semi-quantitative risk assessment techniques are used to derive most of the benefits of the quantitative techniques, and to minimize the resources necessary for a rigorous quantification of risk.

Copper’s Not the Only Way to Network

You have to install a new manufacturing data network. Before you call for a truck-load of twisted-pair copper wire, better check out all the applications. There may be areas where copper won't work.There are other choices. Fiber-optic technology is not new, but is becoming easier to use. Radio frequency is moving from warehouse data collection to sensors and networking.

Intrinsic safety protects your plant against explosions

Explosions can be prevented by limiting the amount of electrical energy available in hazardous areas or by containing the situation using bulky, heavy devices called 'explosion-proof enclosures.' Limiting excess electrical parameters such as voltage and amperage (current) requires the use of energy-limiting devices known as 'intrinsically safe (IS) barriers.' Explosion-proof enclosures prevent or control explosive situations with brute force. They are heavy containers designed to hold an explosion inside. Electrical devices within explosion-proof enclosures can operate at normal power levels.

Ethernet Security, Safety Relies on Common Sense Networking

KEY WORDS Networks and communication Ethernet Internet and intranet PC-based control Device-level networksThe price of freedom? A little less freedom. More users are seeking to gain Ethernet's interoperability and flexibility. However, the relatively greater openness of Ethernet can mean increased network vulnerability, especially when networks are linked via the Internet.
