waste solid and land-filled (ca.
100 kg/yr).
8. PUBLIC EXPOSURE
The notified polymer will not be sold to the public, hence exposure is unlikely, except in the
event of an accidental spill. Given its use in industrial settings as a component of coil
coatings, the exposure to the public to the notified polymer is considered low.
9. ENVIRONMENTAL EXPOSURE
9.1. Release
The polymer solution is a mixture of the notified polymer HP-73-5480 and aromatic
hydrocarbon solvents. Although the solvents are volatile there is expected to be negligible
release of the polymer to the atmosphere as it is not volatile.
Some release of the notified polymer is expected to occur during manufacture of the coating.
Release may occur during blending, batch adjustment and filtration and filling and a spill
would be contained by plant bunding. The notifier estimated that up to 100 kg per annum of
the polymer is likely to be released through accidental spills, equipment cleaning and rinsing
of import drums.
During the coil coating process, no accidental release of the notified polymer is expected as
the process is fully enclosed. Transfer efficiency of the coil coating process is estimated to be
at least 90 %. Cleaning of the application and mixing equipment is estimated to generate
approximately 10 tonnes of waste coating per annum, equating to ca. 6 tonnes of the notified
polymer. Polymer residue from empty coating containers is estimated to be 200 kg per
annum.
The notifier states that all polymer-generated waste during the formulation and application
will be separated out during the distillation process to reclaim solvent from the waste resin
and paint. The residue containing the notified polymer will be converted to an inert solid and
disposed of to landfill or incinerated, with the release of water vapour and oxides of carbon.
It is assumed that the majority of the notified polymer shares the fate of the coated articles. At
the end of their useful lives, they are expected to go to landfill or be recycled, in which case
the polymer would be destroyed by the high temperatures in the blast furnaces.
9.2. Fate
The majority of the waste notified polymer will be disposed to landfill in solid form after
reclamation of the solvents. The polymer is expected to be immobile in landfill due to its
insolubility and is not expected to migrate into the aquatic compartment.
1 May 2001
FULL PUBLIC REPORT
PLC 226 7/13
It is difficult to predict the course of degradation of the notified polymer in the environment,
in the absence of polymer specific physico-chemical data. It is anticipated that the polymer
will slowly degrade via abiotic processes, forming carbon dioxide and water.
Recycling of coated articles will presumably result in the polymer being incinerated and
forming water vapour and oxides of carbon.
It is expected that approximately 3.8 tonnes/yr of the notified polymer will eventually be
disposed of to landfill. The disposed polymer is likely to be in a solid form as residue from
solvent reclamation or as coating on treated articles. In the solid form, mobility and solubility
is expected to be minimal within landfill.
The relatively high molecular weight suggests that bioaccumulation is unlikely to occur
(Connell, 1990).

11. EVALUATION OF ENVIRONMENTAL EFFECTS DATA
No ecotoxicological data were provided.
12. ENVIRONMENTAL RISK ASSSESSMENT
An estimated 100 kg per annum of the notified polymer is expected to be released from
accidental spills, equipment cleaning and rinsing of import drums during formulation of the
coating. The coil coating process in expected to be at least 90 % efficient as it is fully
enclosed, therefore all overspray from application is trapped within the equipment. Each year
cleaning of the equipment is expected to generate ca. 6 tonnes of waste notified polymer and
200 kg residue from empty coating containers.
All waste notified polymer will be converted to an inert solid during the solvent distillation
process. The solid residue will be disposed of to landfill or incinerated with the release of
water vapour and oxides of carbon. In landfill the polymer is expected to be immobile and not
migrate to the aquatic compartment. It is anticipated that the polymer will degrade slowly
through abiotic processes. The majority of the notified polymer will share the fate of the
coated articles at the end of their useful lives. Articles are expected to be landfilled or
recycled.
The environmental risk posed by the polymer when subject to normal use and application is
considered to be low.
13. HEALTH AND SAFETY RISK ASSESSMENT
13.1. Hazard assessment
No toxicological data has been provided on the notified polymer. Considering the high
molecular weight, the notified polymer is unlikely to cross biological membranes. The
polymer meets the PLC criteria and is unlikely to be a hazardous substance according to the
NOHSC Approved Criteria for Classifying Hazardous Substances (NOHSC, 1999b).
The polymer is not isolated from solution. The MSDS for HP-73-5480 SP3 Modified
Polyester Resin, listing 30 to 60 % notified polymer, states that the product may cause eye
and skin irritation, may result in nausea, vomiting and central nervous system depression if
swallowed and may cause irritation to the mucous membranes and respiratory tract if inhaled.
Due to the solvents present (10-30 % aromatic hydrocarbon solvent system), the product is
classed as a dangerous good, Class 3, flammable liquid and carries the following risk and
safety phrases: Xn (harmful), R65 (may cause lung damage if swallowed), S16 (Keep away
from sources of ignition), S23 (do not breath vapour), S24/25 (avoid contact with skin and
eyes) and S62 (if swallowed, do not induce vomiting, seek medical advice immediately and
show the container or label). It is a schedule 5 poison (AHMAC, 1999) due to the aromatic
hydrocarbon content. n-Butanol comes with a NOHSC exposure standard containing a skin
notation.

13.2. Occupational health and safety
There are several stages where handling the notified polymer in solution may result in
exposure. In the polymer manufacturing process skin contact may occur when transferring the
polymer solution (> 60 % notified chemical) to drums and storage tanks. The paint
manufacturing process (details were not provided) is said to be carried out under exhaust
ventilation, however skin contact may occur during and addition of the polymer solution to
the mixer and paint make-up. To minimise contact and prevent off-site contamination,
spillage is contained in bunded areas. Where sampling for laboratory analysis is required,
exposure is most likely to be from skin contact with spillages.
Dermal exposure to the notified polymer in the finished paint (30-50 %) may occur during
paint drumming off and handling of the paint prior to the coil coating process.
The notified polymer is of low concern to worker health and safety and no specific additional
risk reduction measures are necessary. However, given the hazardous nature of the aromatic
hydrocarbon and other solvents contained within the resin solution, exposure will need be
controlled by the use of effective air flow monitoring and ventilation systems to maintain
exposure to levels below the relevant national occupational exposure standard. Further,
personnel will need to wear the appropriate personal protective equipment (PPE). Suitable
PPE includes respirators/face masks, goggles, anti-static flame retardant coveralls, anti-static
footwear, impervious gloves and eye protection with face shields to prevent eye contact. After
coil coating, the notified polymer is fixed to the matrix and is not bioavailable.
The risk to workers in handling the notified polymer is low.
13.3. Public health
The notified polymer will not be sold to the public. Exposure of the general public to the
notified polymer is unlikely, except in the event of an accidental spill. Therefore, the risk to
the public from the notified polymer is considered low.
14. MSDS AND LABEL ASSESSMENT
14.1. MSDS
The MSDS of the notified polymer HP-73-5480 provided by the notifier was in accordance
with the NOHSC National Code of Practice for the Preparation of Material Safety Data
Sheets (NOHSC, 1994a). It is published here as part of the assessment report. The accuracy of
the information on the MSDS remains the responsibility of the applicant.
14.2. Label
The label for the notified polymer HP-73-5480 provided by the notifier was in accordance
with the NOHSC National Code of Practice for the Labelling of Workplace Substances
(NOHSC, 1994b). The accuracy of the information on the label remains the responsibility of
the applicant.

15. RECOMMENDATIONS
No specific measures are required for the notified polymer.
To minimise occupational exposure to HP-73-5480 in solvents, the following guidelines and
precautions should be observed:
Protective personal equipment consisting of at least goggles, gloves and overalls
?br>
should be used during worker exposure to the products containing the notified
polymer;
Employers should ensure that NOHSC exposure standards for all of the components
?br>
of the polymer solution and its paints are not exceeded in the workplace;
A copy of the MSDS should be easily accessible to employees.
?br>
As the resin products containing HP-73-5480 are hazardous to health in accordance with the
NOHSC Approved Criteria for Classifying Hazardous Substances (NOHSC, 1999b),
workplace practices and control procedures consistent with State and Territory hazardous
substances regulations must be in operation (National Model Regulations for the Control of
Workplace Hazardous Substances).
Guidance in selection of protective eyewear may be obtained from Australian Standard (AS)
1336 (Standards Australia, 1994) and Australian/New Zealand Standard (AS/NZS) 1337
(Standards Australia/Standards New Zealand, 1992); for industrial clothing, guidance may be
found in AS 3765.2 (Standards Australia, 1990); for impermeable gloves or mittens, in AS
2161.2 (Standards Australia/ Standards New Zealand, 1998); for occupational footwear, in
AS/NZS 2210 (Standards Australia/ Standards New Zealand, 1994a); for respirators, in
AS/NZS 1715 (Standards Australia/ Standards New Zealand, 1994b) and AS/NZS 1716
(Standards Australia/ Standards New Zealand, 1994c), or other internationally acceptable
standards.
The following emergency procedure is recommended:
HP-73-5480 should be disposed of by using absorbent/inert material (sand, soil) to collect
material and seal in properly labelled containers for disposal. Local emergency services
should be advised if contamination to sewers or waterways occurs.
16. REQUIREMENTS FOR SECONDARY NOTIFICATION
Secondary notification may be required if:
(i) any of the circumstances stipulated under subsection 64(2) of the Act arise. If any
importer or manufacturer of the notified polymer becomes aware of any of
these circumstances, they must notify the Director within 28 days; or
(ii) the notified polymer is introduced in a chemical form that does not meet the PLC
criteria.
