Unknown.

Notifier.
5.1.3 / Transportation and Packaging
Bulk vessels or 205 L drums.

5.2. Operation Description

/ [Discuss in turn: manufacturing, processing, (re)formulation, and/or end use, as applicable]
The lubricant additive packages containing the notified chemical will be transported to customer blending facilities and transferred to bulk storage tanks or retained in steel drums. The additive package is pumped to a blending tank together with other addenda and mineral oil or transmission fluid. After blending the finished product which contains < 2% notified chemical is automatically packed into containers of 2 – 200 L capacity.

5.3. Occupational exposure

Number and Category of Workers
Category of Worker / Number / Exposure Duration / Exposure Frequency
Transport / 3 - 4 / Up to 8 hours per day / 60 days per year
Lubricant blending / 1 – 4 per site (10 sites) / 1 hour per week / 48 hours per year
Mechanics / Hundreds / Up to 8 hours per day / Up to 230 days per year
Exposure Details
Inhalation exposure is unlikely as the notified chemical has a low vapour pressure. Exposure to oil mists will be controlled by local exhaust ventilation. Minor leakage is expected while connecting and disconnecting transfer hoses and cleaning out additive by flushing through with mineral oil. The losses are collected and recycled or sent for disposal. The filling lines will be automatic and exposure of packing operators should be minimal.
Mechanics may experience skin and eye contact while changing oil and handling car parts partially coated with oil. The oil can remain in contact with the skin or eye for an extended period.

5.4. Release

5.4.1 / Release of Chemical at Site
The most likely release of the notified chemical at blending sites or during transport would be from accidental spillage. Losses during transfer and blending are expected to be low as a closed system will be used and any spillage will be contained and absorbed with earth or sand before disposal at an approved industrial facility.
The notifier estimates that about 1% of residues remain inside “empty” containers. If 1000 tonnes of the new chemical are imported per year, then about 10 tonnes will be disposed of by incineration as drum washings during the reconditioning of the containers.
5.4.2 / Release of Chemical from Use
The only end use of the additive package containing the new chemical is expected to be engine oil and transmission fluids where the new chemical will be < 2% of the finished lubricant. There may be some accidental losses when oil is added to vehicle engines or are “topped up”. In the closed system of an automotive transmission, fluids are not frequently changed and the lubricants are effective for the life of the machine. This is not so for engine oils which may be changed about every 5,000 - 10,000 kilometres. As the notified chemical will thermally decompose during use with a concurrent decline in its concentration in the lubricant, there is no expected release of the chemical to the environment under normal conditions of use, except for oil leaks.

5.5. Disposal

A survey by the Australian Institute of Petroleum (AIP, 1995) indicates that of the annual sales of automotive engine oils in Australia, some 60% are potentially recoverable (ie. not burnt in the engines during use). This report also indicates that around 86% of oil changes take place in specialised automotive service centres, where old oil drained from crankcases could be expected to be disposed of responsibly either to oil recycling or incineration. Assuming this is the case, negligible release of the notified chemical should result from these professional activities. The remaining 14% are removed by “do it yourself” (DIY) enthusiasts, and in these cases some of the used oil would be either incinerated, left at transfer stations where it is again likely to be recycled, or deposited into landfill. Meinhardt(2002) estimated that DIY activities account for 7 - 10% of the unaccounted used oil.
According to a survey tracing the fate of used lubricating oil in Australia (Snow, 1997), only around 20% of used oil removed by enthusiasts is collected for recycling, approximately 25% is buried or disposed of in landfill, 5% is disposed of into stormwater drains and the remaining 50% is used in treating fence posts, killing grass and weeds or disposed of in other ways. In a worst case scenario of 14% of the used oil removed by DIY enthusiasts, the notified chemical could be collected for recycling (£ 28 tonnes), buried or disposed of in landfill (up to 35 tonnes), disposed of in stormwater drains (£ 7 tonnes) and used in treating fence posts, to kill weeds or disposed of in other ways (£70 tonnes).
Therefore, about 0.7% of the total import volume of the notified substance could be expected to enter the aquatic environment via disposal into the stormwater system. Since the use of the lubricating oils will occur throughout Australia, all releases resulting from use or disposal of used oil will be very diffuse, and release of the notified material in high concentrations is very unlikely except as a result of transport accidents.
Residues in empty containers from garages and DIY consumers would be disposed of in municipal landfills.

5.6. Public exposure

Dermal and ocular exposure to the public may occur during addition and changing of engine oil and collection and disposal of used oil, and while handling car parts coated with oil.

6. PHYSICAL AND CHEMICAL PROPERTIES

The notified chemical is produced in solution in mineral oil. The following physico-chemical properties are for a typical chemical of the same class as the notified chemical and predominantly reflect the properties of the base oil.
