EDC BARGE AND SHIP LOADING PROCEDURE / ??? PAGE 1 SL 091469 Ethylene Dichloride (EDO is a flammable product. Prior to loading EDO, you must knoleidgeable) in procdures and regulations pertaining to EDC. This section describes the procedures used at the PPG, Lake Charles Compi.es. You must; also refer to the procedures outlined in "PPG Standard Barge Loading, All Barges" and the Code of Federal Regulations V (46 CFR Subchapter 0). Key referencei'are shown below: 46 CFR Subhcapter 0, Part 151.05 Minimum Requiremsnts Cargo Tanks (Vents) - 46 CFR Part 32.55-25 (A-B) Cargo Tanks (Vents) - 46 CFR Part 32.55-30 (C) Flammable Liquid - 46 CFR 30.10-22 Flame Screen - 46 CFR 30.10-25 \ fEDC is a grade C flammable liquid. The Chemical Data Guide extinguishing agents for EDC are C02, dry chemical, foam, and water fog. The short exposure tolerence for EDC is 200 ppm for one hour. Hands-on-training shore tank arrangement, piping dystem and valving will be given in the field by a .^qual i fiedi ^ cXfywfali trainer. Classroom training will consist of b$pks, //- Chemical Data Guide and PPG training manuals. There is a special requirement with EDC pertaining to the person in charge (PIC) of an EDC transfer. Since EDC is a flammable product, the Code of Federal Regulations (46 CFR 151.45-4) loading. requires a cert;iified tankerman to be in chargeof-tiu. Ott^t ri r k.

In the case of EDC transfers to a ship, the ship's master or mate will serve to meet the requirenr-nt of the licensed PIC, so a lead tankerman would not be needed. EDC barge loading can be done at either Docks' "A" cr "C". EDC ships can be loaded at either Dock^ "A" or "C. Following is a step-by-step procedure for loading EDC. Where noted* T.V. will apply to Tank Vessels (ships) and T.B. will apply to Tank Barges. Pre-Loading and Inspect i_on Requirements 1. (TB) Spot the barge.

Prior to loading EDC, you must be knowledgeable in procedures and regulations pertaining to EDC, This section describes the procedures used at the PPG, Lake Charles Complex. You must also refer to the procedures outlined in "PPG Standard Barge Loading, All Barges" and the Code of Federal Regulations (46 CFR Subchapter 0). Key references are shown below.

The Chemical Data Guide extinguishing agents for EDC are COg, dry chemical, foam, and water fog. The short exposure tolerance for EDC is 200 ppm for one hour. Hands-on-training in shore tank arrangement, piping system and valving will be given in the field by a qualified trainer.
