State Safety Control

When the first of our new pilot plants was designed we had the option of full computer control. We decided to Install stand-alone solid state controllers and safety systems to allow the fullest operating flexibility and the best possible data retrieval. The computers chosen for the latter have the capability when we wish to control temperature, pressure or feeds using our own algorithms.

Requirements for controlling potential hazards associated with analytical x-ray systems are specified in most states by law. For example, at Ames Laboratory these requirements are detailed in the Radiological Protection Program or Policy 10202.003, Analytical X-ray Safety . Portions of these hazard control and safety measures are summarized below. 

Both state and federal regulations specify design parameters and associated equipment for solvent emission control and safety. The recommendations offered in this section are based on good engineering and experience, but do not guarantee compliance with national or local regulations, or both. 

One of the key assumptions underlying the approach to safety described in this book is that systems adapt and change over time. Under various types of pressures, that adaptation often moves in the direction of higher risk. The good news is, as stated earlier, that adaptation is predictable and potentially controllable. The safety control structure must provide protection from and appropriate responses to the continuing influences and pressures that tend to degrade safety over time. More... 

The Internal control system is by no means a Norwegian invention. It has been developed inter alia in the U.S. car and aviation industries over several decades. But Norwegian regulations in the last twenty-hve to thirty years have taken the system a step further by more explicitly making it a distinct formal part of the state safety regulation regime, not just a matter for industry s internal organising of achvihes. 

The term control is not precise, it may mean just the passive checking, or it may denominate the active steering - taking control. When describing state safety control, it is preferable to make a distinction between these two. The passive control implies to verify or audit the industry s operations, whereas the active steering requires that the passive control is followed by administrative decisions directed towards the industry. See further Subsection 5.4.4 on administrative decisions linked to control. 

The internal norms may surface in internal procedures, technical project specifications, operating manuals and the like. These documents will in turn constitute relevant objects for state safety control state supervisory bodies evaluate the solutions and may react by requiring amendments to be made. More likely, the choices made by industry will be reviewed by the supervisory bodies in the context of the industry s applications for the various approvals, permits and licences needed to conduct the petroleum activities.

In relation to state safely management, the internal control provides an important input and basis for state safety eontrol (4) in that reports and the like flowing from the industry s own eontrol activities in practice quantitatively eonstitute the most eentral input - more eentral than supervision and verification carried out directly by state inspectors. This means that the quality of the internal control and its output have to be secured. Therefore, the internal control also constitutes a separate object of state control in order to ensure that it can serve the intended purpose. The internal control is made both a basis and an object for state safety control. 

Introduction of a system of state safety control and regulation. 

Dr. Goble has a BSEE from Penn State, an MSEE from Vilanova and a PhD from Eindhoven University of Technology in Reliability Engineering. He is a registereed professional engineer in the State of Pennsylvania and a Certified Functional Safety Expert (CFSE). He is a fellow member of ISA and previous author of the ISA book Control Systems Safety Evaluation and Reliability. 

The best opportunity for a change in the safety culture lies where the work is carried out—at the workplace. This principle of point of control states The greatest potential for control tends to exist at the point where the action takes place. 

Allows only safe products to be placed on the market and meet a high level of protection of safety. Gives member states authority to control the safety of products and take the appropriate measures. Sets up a system of rapid exchange of information on defective products at national and Community levels. Information is passed to all member states and possible publishing in the Official Journal (negative PR). 

Level FIA The safety functions needed to reach a controlled state in design basis category 3 and 4 conditions and certain category 2 conditions. 

Controlled state In DBC 2 (incident conditions), or DBC 3 4 conditions (accident eonditions) or in complex sequences, the plant is in a controlled state if the following conditions are ensured by operator actions or by the active or passive safety features ... 

A system important to safety, i.e., provided to ensure the safe shutdown of the equipment or otherwise control an operation or to limit the consequences of anticipated operational occurrences and design basis incidents. Safety systems consist of the protection system, the safety actuation systems, and the safety system support features. Components of safety systems may be provided solely to perform safety functions, or may perform safety functions in some plant operational states and non-safety functions in other operational states. Safety system support features are considered the collection of equipment that provides services such as cooling, lubrication, and energy supply required by the protection system and the safety actuation systems. 

The assessment of severe accidents should account for the full design capabilities of the plant, including the use of some safety and non-safety systems beyond their originally intended function to return the potential severe accident to a controlled state and/or to mitigate its consequences. If credit is taken for extraordinary use of systems, there should be a reasonable basis to assume they can and will be used as analysed. 

There are currently no non-radiological hazardous chemicals in K-Reactor or in the L- or P-Reactor Disassembfy Basin in suffident quantities to pose a safety concern to the workers, public, or the oxvironmait Shmild hazardous chemicals be brought into K-Reactor or in the L- or P-Reactor Disassonbly Barin that are not on the allowable chemical fist or in excess of the ma dmum allowable quantities, contrary to the adadministrative controls stated in Section 7.2.4, the safety concerns may be created (Ref 8-51). 

As stated in DOE-STD-3009-94, a preparation guide for U.S. DOE Nonreactor Documented Safety Analysis reports, "It is not the intention of the DSA to cover safety as it relates to the common industrial hazards that make up a large portion of basic OSHA regulatory compliance." Therefore, in the context of 10 CFR 830, Subpart B requirements, the scope of HAZWOPER is taken to include those hazards, associated controls, and safety and health (S H) programs that must be identified and maintained within a Hazard Category 1, 2, or 3 facility s safety basis.

Annex G provides a pictorial and verbal display of the Hierarchy of Controls listed in Section 5.1.1 with application examples for each element. In Chapter 12, Hierarchy of Controls The Safety Decision Hierarchy, the state-of-the-art is moved forward through extensions that this author believes are now necessary in the first step within the hierarchy Elimination. Also, the hierarchy is enveloped within a sound problem-solving technique. The chapter includes a section titled The Logic of Taking Action in an Order of Effectiveness. ... 

In the United States, the Center for Chemical Process Safety (CCPS) is primarily responsible for establishing H RA guidelines. CCPS developed Guidelines for Safe Automation of Chemical Processes," which established criteria for the H RA related to control and safety systems. In the United States, the International Society of Automation (ISA) is primarily responsible for establishing standards in the field of instrumentation and controls. The ISA SP84 committee developed ANSI/ISA-84.01-1996. 

The level and sophistication of instruments and process control systems is largely determined by local preference although in order to satisfy the basic requirement, as stated above, there is a minimum requirement for instrumentation, control and safety interlocks which are common to all sulphonation plants.
