Technical safety

A suitable maintenance strategy should be developed for equipment by considering the criticality and failure mode, and then applying a mixture of the forms of maintenance described above. In particular, the long-term cost of maintenance of an item of equipment should be estimated over the whole life of the project and combined with its capital cost to select both the type of equipment and form of maintenance which gives the best full lifecycle cost on a discounted basis), while of course meeting the technical, safety and environmental specifications. 

Some companies that let toll contracts have been known to work with small tollers who displayed excellent technical, safety, and quality characteristics to help them achieve the necessary higher production capacity. This is feasible if the time frame allows and a closer relationship is mutually beneficial. 

After many years of improvements in technical safety methods and process design, many orgaruzations have found that accident rates, process plant losses and profitability have reached a plateau beyond which further improvements seem impossible to achieve. Another finding is that even in orgarriza-tions with good general safety records, occasional large scale disasters occur which shake public confidence in the chemical process industry. The common...

Preventive and protective measures. Technical safety measures must always be developed no matter how inherently safe we think the process is. The scope of preventive and protection measures is large for the whole plant. Below, some preventive measures to be taken to prevent thermal runaways when a dangerous situation is recognized are listed ... 

A technical safety barrier represents technical equipment, whose function it is to arrest the accident/incident evolution so that the next event in the chain will not be realised. The human safety barrier is the suitable people, whose function it is to intervene and arrest the accident/incident evolution so that the next event in the chain will not be realised. The organizational safety barrier is the procedures, rules, guidelines, etc. present, which function to arrest the accident/incident evolution so that the next event in the chain will not be realised. In this thesis the latent conditions and precursors in an unfolding situation are considered to have three possible effects on the safety barriers negative, positive or none at all. 

In addition to these selection criteria, the limitations of the author s contacts and the willingness of companies to participate, narrowed the search for a suitable case down to a small Dutch company (< 30 people). This company produces in batches, falls under the Dutch Seveso-II directive (BRZO, 1999) and authorized access to the relevant data. The selected company had experienced some serious accidents recently, in spite of using many technical safety systems. Thus the management was aware of the necessity to enhance both safety and the reliability of the operational process. 

In the Technical Safety Laboratory of Eastman Kodak, the role played by calorimetric methods (such as High Pressue DSC and ARC techniques) in assessing the stability of chemicals and processes, though a central one, is but part of a range of techniques used for this overall purpose. The relations between these methods is discussed and presented in the form of logic flow diagrams.

As oil production from available crude oil stocks declines, UK Land Forces and the Royal Navy will continue to demand fuels that meet its existing technical, safety and environmental requirements, most of which were written around the existing technology-fuel model. For the Navy, these... 

Critical instruments assigned a Class 1 include those necessary to avoid a failure which may cause the perils listed above or instruments which fail to inform of upset conditions which may result in perils. Testing of these instrument systems may be mandated by regulatory agencies, in-house technical safety review committees, HAZOP studies, or designated as critical by operations supervisors. All of these shutdown systems and alarms must be prooftested in accordance with a proper schedule. [8]... 

The Safety Instrumented Systems (SIS) and critical alarms assigned a Class 1 include those that have been mandated as such by state or federal agencies an in-house technical safety review committee HAZOP studies and specific alarms deemed critical by operations supervisors. All of these Safety Instrumented Systems and alarms are on a regular prooftesting schedule.

Ordinarily the details of the incident investigation within the investigation report are reviewed by the appointing authority, middle management, or sometimes with a technical safety review committee before the report is issued. 

This trade association supports the chlor-alkali industry by fostering continuous improvements to safety, the protection of human health, and the environment, with regards to production of caustic soda, chlorine, and related products. The Chlorine Institute provides numerous technical safety and engineering pamphlets that are developed by leaders within the industry and also focuses on regulatory and legislative matters.

The inspection of process vessels and storage tanks represent examples of closed-space inspection. It is necessary for the management to define the closed-space inspection and provide a set of regulations for inspection. The chosen inspector must be aware of all the regulations defined by the management for inspection, along with the permission for inspection. Before entry all the technical safety requirements must be met. It is also necessary that the inspector in the closed-space process vessel must be in constant communication with other personnel outside during the entire duration of inspection. It is also possible to use mechanical robotic systems in some cases to avoid the hazards involved in closed-space entry for inspection. 

Supervision of producers and importers as primary suppliers of chemicals is a task requiring specific skills and qualifications on the part of inspectors, e.g. in toxicology and hazard assessment. To supervise retail sales is a simpler type of control. Supervision of users is, again, more complex, requiring still other types of inspector skills and qualifications for assessment of exposure and of risks, control of technical safety measures, etc. 

The ICH process reflects lessons learned from the long and at times bitter discussions leading to the opening of EMEA in 1996. Both ICH and EMEA do more than find common ground for agreement on technical safety standards. 

Every procedure must be reviewed and approved, as described in Chapters 5 and 7. Each writer should be knowledgeable in the process for reviewing and approving procedures at their site. As determined using the information presented in Chapter 7, technical, safety, environmental and quality review considerations should be established for review and approval.
