Operating Instructions

Develop operating instructions on the correct or permitted connections between tanks and vessels... 

Develop and implement operating instructions to control feed temperature and shut off feed when temperature rises above a certain level... 

Implement operating instructions to maintain liquid level above heating surface at all times Install automatic level control with low level alarm and shutdown of liquid withdrawal system to ensure liquid is above heating surface at all times... 

Monitor exterior wall temperature with infrared optical detection system, and operating instructions for operator response if high temperature signal occurs... 

Lines are not Follow proper operating instructions depressurized, Install or use small bleed valves before disconnecting. CCPS G-22 CCPS G-23 CCPS G-29... 

Has each task that has been identified as critical in the area of quality and/or safety been documented with full operating instructions and are these instructions reviewed regularly ... 

In order to maintain a high level of quality and safety in the actual operations, whether chemicals are transferred, loaded/unloaded or transported, proper operating instructions/procedures are crucial and should be regularly reviewed. 

It should be expected that tasks for all operations are defined and those critical to quality and/or safety are identified. Critical tasks should have detailed operating instructions. 

Clear, unambiguous operating instructions (updated and freely available). 

Provision of operating instructions and procedures. These should eliminate confusion and provide continuity on, e.g., shift changeover. EiTors in identification of valves, pumps, pipes, storage tanks, and the sequence in which they are to be operated is a common cause of accidents, e.g. on staff changeovers. 

Hazard and operability study prior to implementation (repeat when in use) Updating of all operating instructions, notices, procedures Removal/isolation of obsolete plant/lines Control of changes in personnel (see training)... 

Provision of clearly written operating instructions, accessible to operators, referring to numbered/identified plant items, covering Start-up and shutdown... 

Computerized process control systems add complexity to operating instructions. These operating instructions need to describe the logic of the software as well as the relationship between the equipment and the control system otherwise, it may not be apparent to the operator.

For a quality manual to be a manual it should contain the procedures and instructions, as does a computer manual or a car maintenance manual, so whether one volume of the manual contains or refers to other documents does not prevent the collection of documents being referred to as the quality manual. Manuals tend to include operating instructions, hence the word manual. The quality manual should therefore contain all the policies and practices but not necessarily in one volume. 

Produce procedures that govern the generation, proving, and publication of product/ service support documents, such as handbooks, operating instructions, etc. 

Process specifications, maintenance specifications, operating instructions, etc. 

Estimates of flow rates, residence times, and time required to shut off flows can be used to calculate estimates of potential release quantities. Such information can often be obtained from operating instructions. 

Error free operation and maintenance can only occur within an effective management system. At the level of the task itself, this is provided by operating instructions. However, at a more global level, separate tasks have to be organized in a systematic manner, particularly if hazardous operations are involved, and where several individuals need to coordinate to achieve an overall objective. This section illustrates some accidents due to poor organization of work or failure to carry out checks. 

The worker knew that valve A had to be closed. However, it was believed by the workforce that despite the operating instructions, closing B had a similar effect to closing A and in fact produced less disruption to downstream production. Possible cause violation as a result of mistaken information and an informal company culture to concentrate on production rather than safety goals (wrong intention). 

The PIF concept is also useful during the process of design. Design guidelines to maximize the usability of plant and to minimize the potential for error can be based upon comprehensive descriptions of PIFs such as the factors which determine the most effective presentation of information in control rooms, or the characteristics of usable and clear operating instructions. 

Which often lead to violations. The following deficiencies may occur in any applications of procedures, from operating instructions to permit to work systems ... 

In many industries, rule books have a tendency to become enshrined as policy statements, either for internal or external regulatory purposes. Unfortunately, the format that is appropriate for a regulatory or standards document is unlikely to fulfill the requirements of an effective operating instruction or procedure to provide assistance in carrying out a task effectively. 

Information on the types of human interactions with hazardous systems that occur would be obtained from sources such as plant operating instructions, job safety analyses and similar sources. These interactions are referred to as critical tasks (CT). 

Unconditional Probability (weighted sum) that Effective Operating Instructions are. 255. 744 ... 

Similar assessments are performed to evaluate the probability that effective operating instructions are available (Table 6) that staffing levels are adequate (Table 9) and that time pressure will be high or low (Table 10). In this latter case, since three influences impact upon time pressure, eight joint assessments need to be made.
