REACTIVE CHEMICALS SELF EVALUATION
SUBJECT:
Scenarios
SUMMARY:
Train III MODV programming automatically handles many possible scenarios. Trains 1 & 2 and TDC and Modicon based and require operator response.
IMPROVEMENTS:
Management of Change.
STRENGTHS:
All out of range conditions are alarmed. MOC "major" required to modify those related to critical Instruments. Other changes require lower level MOC.
OPPORTUNITIES:
Automation of Train 1 & 2 emergency response.

* REACTIVE CHEMICALS SELF EVALUATION
SUBJECT: SUMMARY:
Cata1ysts
Catalysts for the Solution Process are deactivated by excess temperature and exposure to calcium stearate and water.
IMPROVEMENTS:
Management of Change.
STRENGTHS:
Excess or runaway temperatures would "kill" the catalyst. All catalyst product ion is fully MODV control 1ed.
OPPORTUNITIES :
Removal of "catalyst kill" from the recycle solvent loop to dramatically improve efficiency.

SUBJECT:
Lab Chemical Storage
SUMMARY:
Lab chemicals are stored outside in "flammable11 cabinets. Block inventory lab chemicals is managed by block Sr. Quality Assurance Specialist.
of
IMPROVEMENTS:
Management of Change.
STRENGTHS:
No lab chemicals are stored in large enough quantities to require drum storage.
OPPORTUNITIES:
Consider the need for a plant policy on lab chemical ownership, auditing and receiving. Consider the need for a Reactive Chemicals Chart for Lab Chemicals.

REACTIVE CHEMICALS SELF EVALUATION
SUBJECT:
Waste Handling
SUMMARY: IMPROVEMENTS:
The Solution Polyethylene process solvent balance is ~7 mmlb/yr positive. This excess solvent has to be loaded, shipped and burned at Environmental Operations. The only absorbent material utilized is 3M's Oil Sorbent polypropylene (100#) cloths.
Management of Change, Ongoing capital project to recycle and reuse "50# of the excess.
STRENGTHS:
Written procedures employed.
OPPORTUNITIES:
Further Investigate the reactive chemicals potential of the portable waste trailer that is routinely used for waste containment within Poly C.
