Īn approach for a risk management program for electronic records and signatures can be found in the corresponding GAMP document. Identify levels of control that exist or will be needed for these records. Finally, application level security and associated authority checks control access to the computer system applications (applications security). The access to individual computer system platforms is controlled by network specific security procedures ( network security).
Procedural controls must govern the physical access to computer systems ( physical security). Security must be instituted at several levels.

A similar trip system was insulted in the gas feed line from the HP separator to the power station. An emergency trip system that automatically shuts a valve in the appropriate separator gas line to isolate the separator from the compressor suction drums when a high foam level occurs was added also. Permanent gamma ray scanning equipment was installed on each separator along with foam density and level recorders in the process control room. Minimum instrumentation shall include level indication, temperature recording controller, pressure gauge, and pressure relief valve. The tank for hot storage is steam jacketed and insulated for temperature maintenance. A steam jacketed sterile vent hlter must be used to avoid condensation in the hlter and the vent hlter housing temperature controlled. Tanks for hot loop and steam sterilizable line must be designed to withstand steam sterilization (121☌). Tanks with vent hlters must be designed for pressures of -20 kPa and +100 kPa and must be equipped with a rupture disk.

The reflux drum level recorder controller (LRC) would close off to catch to falling level, and the overhead product rate would drop, in proportion to the increase in reflux rate. But the liquid level in the reflux drum would begin to drop.

If the reboiler were on manual control, then the flow of steam and the reboiler heat duty would remain constant as the reflux rate was increased, and the weight flow of vapor up the tower would remain constant as the top reflux rate was increased. The statement that the mass, or weight flow of vapor through the trays, increases as the refluxed rate is raised is based on the reboiler being on automatic temperature control. Instrumentation on the solvent extraction equipment will usually consist of recording flow and recording temperature controllers on the feed stream, a pressure controller on the raffinate exit line, temperature recorders on the column intercoolers, and a liquid level recording controller at the liquid-liquid interface to set the extract layer withdrawal rate.
