Expanding Beyond Minimum Requirements

In deciding on the scope for initial PSM implementation, many companies choose to limit the scope of their effort. This is often a realistic approach, since initial implementation can be complex even within a limited range of chemicals and processes. 

For example, initial implementation may be confined to those chemicals and processes covered by the OSHA process safety rule, which is limited to a specific list of chemicals and excludes processes that meet specific criteria. However, the OSHA regulation does not cover all materials and processes that may represent process risks. 

In a facility that has adopted PSM systems for some of its processes and chemicals, expansion of PSM may simply involve using the same management systems consistently throughout the plant. 

For a plant that has not adopted PSM in the initial round of design, development, and installation, expansion requires repeating the installation process described in Chapter 7. In such a case, your systems are already designed and the effort required is a continuation of the roll-out a full pilot test should not be necessary. 

Another expansion of initial PSM installation is in implementing more demanding requirements. Your initial PSM design was derived from a design basis that included such considerations as a frequency for updating process

As liquid flowrate inereases beyond the minimum required to suspend the partieles, the bed expands. Unfortunately, however, the expansion index n is not eonstant over all flow regimes but is a funetion of the flow. Thus... 

This model can hardly be more unUke a universe that expands in three-dimensional Euclidean space. The special-relativistic requirement of foru -dimensional space, with the cru vature of general relativity superimposed, seems to demand that space-time has a minimum of five dimensions, which is equivalent to four-dimensional projective space, described by five homogeneous coordinates. Locally perceived three-dimensional space therefore is an illusion and extrapolation of local structure, beyond the Galactic borders, a gross distortion.
