For direct addition to unleaded petrol, the components for the petrol blends are similarly drawn directly from their storage tanks, blended and then sent to another product storage tank or directly to petrol delivery trucks. Some petrol may be drummed off. The final blended petrol will be distributed to service stations and convenience stores by tank truck. 6. OCCUPATIONAL EXPOSURE Exposure The identifies the nature of work done where occupational exposure to the notified polymer (in additive package) may occur at either the petrol blending terminal (petrol) or at the aftermarket blending plant (aftermarket).

Cleaning (2) 6.1.1 Marine Terminals The additive packages containing the notified polymer will be imported in drums and 5200 L isotanks. Occupational exposure is not likely except in the event of a spill. 6.1.2 Petrol Blending During unloading workers will fasten a four inch hose to the bottom of the iso-container, to enable the additive package to be pumped to a storage tank. Fastening takes about 10 minutes. A special air back flush system is used to prevent spillage during transfer. The notifier estimates that by adhering to ISO 9001 procedures spills and leaks are less than 50 grams of additive package per unloading operation. For unloading of drums workers will connect a pump line to the drum. For unloading of both iso-containers and drums incidental skin contact to splashes, drips and spills may occur as pump lines are connected or disconnected. Whole body exposure to mist may occur if emptied drums are steam cleaned for re-use or disposal.
