Table 4.5 Checklist Analysis of Dock 8 HF Supply System

MATERIAL

Do all raw materials continue to conform to original specifications? Yes. The cylinders are

ordered with the same anhydrous HF specification used since startup.

Is each receipt of material checked? No. There have been no problems with the supplier, so no

such check has been considered. Investigate consequences of receiving material other than HF.

Consider adding such checks on HF receipts.

Does the operating staff have access to Material Safety Data Sheets? Yes. All staff are

familiar with the process chemistry, including the hazards of HF.

Is fire fighting and safety equipment properly located and maintained? Yes.

EQUIPMENT

Has all equipment been inspected as scheduled? Yes. The maintenance personnel have

inspected the equipment in the process area according to company inspection standards. Given

the corrosivity of HF, inspections may have to be more frequent.

Have pressure relief valves been inspected as scheduled? Yes.

Have rupture discs been inspected (for having blown) as scheduled? Yes. Though none have

failed, procedure calls for inspection of rupture disc and installation after maintenance.

Are the proper maintenance materials (parts, etc.) available? Yes. They include spare pigtails

for the supply cylinders as well as properly rated rupture discs. Other items must be ordered.

PROCEDURES

Are the operating procedures current? Yes.

Are the operators following the operating procedures? Yes. No significant violations of

procedures have been noted.

Are new operating staff trained properly? Yes. Training includes a review of the PrHA for this

process and familiarization with MSDSs.

How are communications handled at shift change? If an HF cylinder needs to be changed out

near a shift change, the change is scheduled to be performed by either, but not both, shifts.

Is housekeeping acceptable? Yes.

Are safe work permits being used? Yes.
