The physical properties of the principal constituents of natural gas are Hsted in Table 5. These gases are odorless, but for safety reasons, natural gas is odorized before distribution to provide a distinct odor to warn users of possible gas leaks in equipment. Sulfur-containing compounds such as organic mercaptans, aUphatic sulfides, and cycHc sulfur compounds are effective odorants at low concentrations and are added to natural gas at levels ranging from 4 to 24mg/m. ... 

The principal advantage of equation based, dynamic, simulators is their ability to model the unsteady-state conditions that occur at start-up and during fault conditions. Dynamic simulators are being increasingly used for safety studies and in the design of control systems. 

In keeping with the cardinal principal of safety in the explosives industry, cleaning product pipelines by the pig method exposes personnel to the least amount of hazardous material for the shortest period of time and reduces potentially hazardous disassembly operations to the minimum. 

Process Reliability Simulation VIP The process reliability simulation VIP is the use of reliability, availability, and maintainability (RAM) computer simulation modeling of the process and the mechanical reliability of the facility. A principal goal is to optimize the engineering design in terms of life cycle cost, thereby maximizing the project s potential profitability. The objective is to determine the optimum relationships between maximum production rates and design and operational factors. Process reliability simulation is also applied for safety purposes, since it considers the consequences of specific equipment failures and failure modes. 

The use of water pumps in sampling equipment presents no problems under laboratory conditions with respect to performance and the vacuum obtained. For safety reasons as well as the considerable water consumption, their long-term use is, however, avoided. Their principal disadvantage is that they cannot be installed under field conditions.

Hazards noted, physical or operational, are to be viewed as being representative of possible deficiencies in management systems. A management that wants to achieve a change in culture is best served if the deficiencies noted and the proposals made in audit reports for improvement principally effect safety management systems. 

Dan Petersen is a consultant who has stressed, among other things, the significance of accountability for safety being well established—at all levels. He is the principal presenter in a video and disc-based program titled Safety Accountability. Its message to senior management is this ...

Although the responsibility for safety in a department or other administrative unit lies with its director or chairperson, the responsibility for the delineation of the appropriate safety procedures and the instruction of those who will carry out the operation lie with the project manager or principal investigator. The responsibility for safety during the execution of an operation lies with those technicians, students, and other workers who actually perform that operation. Nevertheless, the primary responsibility for maintaining safe behavior in a safe laboratory environment remains with the project manager or principal investigator. Each institution should develop policies that... 

The convenience of size exclusion chromatography (SEC) as a means for the determination of the molecular mass distribution of a wide variety of synthetic polymers was appreciated early [1]. It was developed, however, for low-temperature application principally for reasons of safety and ease of use. Tetrahydrofuran, THF, had been adopted as a general-purpose mobile phase, and its low boiling point and the ease with which it formed peroxides restricted its use to temperatures below 40°C. This meant that many commercially important polymers, such as polyethylene, polypropylene, and polyaryl ether ketone could not be analysed, since they required high temperatures for dissolution. The high-boiling halogenated aromatics and substituted phenols were found to be suitable solvents for these polymers, and with increased temperature the scope for SEC was vastly increased. 

The Agency s principal safety and health information network is made up of a Focal Point in each European Union Member State, in the four E A countries and in the 13 candidate countries (CCs) to the European Union. This network is an integral part of the Agency s organization and plays an important role within the Agency structure. Focal Points are nominated by each government as the Agency s official representative in that country and are normally the competent national authority for safety and health at work. 

CDM are the initial letters of the Construction (Design and Management) Regulations 1994, which place responsibilities for safety on construction sites on everyone involved, from the designer and the client to principal and sub-contractors.
