7.0 DESIGN FEATURES AND ADMINISTRATIVELY
CONTROLLED LIMITS AND REQUIREMENTS
Criticality safety of this operation depends on maintaining all solution in safe geometry.
Proper spacing (at least 12-inches edge-to-edge) must be maintained between
multiple process containers, or between process containers, safe tanks, and vacuum
Spills or leaks must be collected in approved solution containers such as safe bottles
or 4-liter beakers.
If the final wet vacuum trap is in the northwest corner of Room 1022 alarms, vacuum
transfer must be immediately stopped. The source of solution must be determined
and corrected before further use of wet vacuum.
Large geometry containers or equipment (internal volume available for solution
holdup exceeding 4 liters) are not permitted near this process equipment without
Criticality Safety approval.
8.0 SUMMARY AND CONCLUSIONS
It has been shown in section 5.0 that the proposed trap is a safe geometry and meets the
requirements of the double contingency principle.
