FOOTNOTES
1 PROTECTIVE ACTION ZONE is defined as the area in which people are at risk of harmful exposure. This zone
assumes that random changes in wind direction confines the vapour plume to an area within 30 degrees on
either side of the predominant wind direction, resulting in a crosswind protective action distance equal
to the downwind protective action distance.
2 PROTECTIVE ACTIONS should be initiated to the extent possible, beginning with those closest to the spill
and working away from the site in the downwind direction. Within the protective action zone a level of
vapour concentration may exist resulting in nearly all unprotected persons becoming incapacitated and
unable to take protective action and/or incurring serious or irreversible health effects.
3 INITIAL ISOLATION ZONE is determined as an area, including upwind of the incident, within which a high
probability of localised wind reversal may expose nearly all persons without appropriate protection to
life-threatening concentrations of the material.
4 SMALL SPILLS involve a leaking package of 200 litres (55 US gallons) or less, such as a drum (jerrican or
box with inner containers). Larger packages leaking less than 200 litres and compressed gas leaking from
a small cylinder are also considered "small spills".
LARGE SPILLS involve many small leaking packages or a leaking package of greater than 200 litres, such as
a cargo tank, portable tank or a "one-tonne" compressed gas cylinder.
5 Guide 129P is taken from the US DOT emergency response guide book.

MATERIAL DATA
Odour Threshold Value: 0.00024 ppm (detection), 0.00037 ppm (recognition)
Saturated air at 20 deg C and 1 atm. contains 38500 ppm ethyl acrylate by
volume.
Exposure at or below the recommended TLV-TWA is thought to protect the
worker from the significant risk of severe eye, nose and skin irritation
and to minimise irritant effects of chronic exposure to ethyl acrylate
vapour. The reported ability of ethyl acrylate to induce skin sensitisation
in exposed human volunteers suggest that some individuals may be
hypersensitive or otherwise unusually responsive from exposure to certain
chemicals - these individuals may NOT be adequately protected from adverse
health effects at the TLV-TWA.
Foetotoxic effects were seen after oral administration to rats.
INGREDIENT DATA
HYDROQUINONE:
The recommended TLV-TWA takes into account the toxicology of hydroquinone
and experience of industrial exposures to benzenediols. Exposure at or
below the limit is thought to minimise the risk to workers of eye injury,
dermatitis and central nervous system effects. A short-term duration
exposure value has not been recommended, because no quantitative data as
to the levels of hydroquinone which produce eye irritation or more serious
corneal changes has been identified.
4-METHOXYPHENOL (MEHQ):
MEHQ has caused ocular toxicity in animals and skin depigmentation in
rodents and workers. The recommendation for the TLV-TWA arises from
documented eye and skin toxicities and by analogy with hydroquinone.
PERSONAL PROTECTION
EYE
路 Chemical goggles.
路 Full face shield may be required for supplementary but never for primary protection of
eyes
路 Contact lenses may pose a special hazard; soft contact lenses may absorb and
concentrate irritants. A written policy document, describing the wearing of lens or
restrictions on use, should be created for each workplace or task. This should include a
review of lens absorption and adsorption for the class of chemicals in use and an account
of injury experience. Medical and first-aid personnel should be trained in their removal
and suitable equipment should be readily available. In the event of chemical exposure,
begin eye irrigation immediately and remove contact lens as soon as practicable. Lens
should be removed at the first signs of eye redness or irritation - lens should be
removed in a clean environment only after workers have washed hands thoroughly. [CDC

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
ENGINEERING CONTROLS
Use in a well-ventilated area.
General exhaust is adequate under normal operating conditions. Local exhaust ventilation
may be required in specific circumstances. If risk of overexposure exists, wear approved
respirator. Correct fit is essential to obtain adequate protection. Provide adequate
ventilation in warehouse or closed storage areas. Air contaminants generated in the
workplace possess varying "escape" velocities which, in turn, determine the "capture
velocities" of fresh circulating air required to effectively remove the contaminant.
Type of Contaminant: Air Speed:
solvent, vapours, degreasing etc., evaporating 0.25- 0.5 m/s (50- 100 f/min)
from tank (in still air).
aerosols, fumes from pouring operations, 0.5- 1 m/s (100- 200 f/min.)
intermittent container filling, low speed
conveyer transfers, welding, spray drift,
plating acid fumes, pickling (released at low
velocity into zone of active generation)
direct spray, spray painting in shallow booths, 1- 2.5 m/s (200- 500 f/min.)
drum filling, conveyer loading, crusher dusts,
gas discharge (active generation into zone of
rapid air motion)
grinding, abrasive blasting, tumbling, high 2.5- 10 m/s (500- 2000 f/min.)
speed wheel generated dusts (released at high
initial velocity into zone of very high rapid
air motion).
Within each range the appropriate value depends on:
Lower end of the range Upper end of the range
1: Room air currents minimal or favourable to 1: Disturbing room air currents
capture
2: Contaminants of low toxicity or of nuisance 2: Contaminants of high toxicity
value only.
3: Intermittent, low production. 3: High production, heavy use
4: Large hood or large air mass in motion 4: Small hood- local control only
Simple theory shows that air velocity falls rapidly with distance away from the opening
of a simple extraction pipe. Velocity generally decreases with the square of distance
from the extraction point (in simple cases). Therefore the air speed at the extraction
point should be adjusted, accordingly, after reference to distance from the contaminating
source. The air velocity at the extraction fan, for example, should be a minimum of 1-2
m/s (200-400 f/min) for extraction of solvents generated in a tank 2 meters distant from
the extraction point. Other mechanical considerations, producing performance deficits
within the extraction apparatus, make it essential that theoretical air velocities are
multiplied by factors of 10 or more when extraction systems are installed or used.

CONDITIONS CONTRIBUTING TO INSTABILITY
Avoid any contamination of this material as it is very reactive and any contamination is potentially hazardous.
路 Material contains a stabiliser / polymerisation inhibitor system that provides workable but not indefinite shelf life
路 Storage at higher temperatures and long term storage may result in polymerisation with solidification. In larger
路 DO NOT open hot exotherming drums - cool externally with water to avoid vapour release.
路 Polymerisation may occur at elevated temperatures.
路 Polymerisation may be accompanied by generation of heat as exotherm.
路 Process is self accelerating as heating causes more rapid polymerisation.
路 Exotherm may cause boiling with generation of acrid, toxic and flammable vapour.
路 Polymerisation and exotherm may be violent if contamination with strong acids, amines or catalysts occurs.
路 Polymerisation and exotherm of material in bulk may be uncontrollable and result in rupture of storage tanks.
路 Polymerisation may occur if stabilising inhibitor becomes depleted by aging.
路 Stabilising inhibitor requires dissolved oxygen to be present in liquid for effective action.
路 Specific storage requirements must be met for stability on ageing and transport.

Contact allergies quickly manifest themselves as contact eczema, more rarely as urticaria
or Quincke's oedema. The pathogenesis of contact eczema involves a cell-mediated (T
lymphocytes) immune reaction of the delayed type. Other allergic skin reactions, e.g.
contact urticaria, involve antibody-mediated immune reactions. The significance of the
contact allergen is not simply determined by its sensitisation potential: the
distribution of the substance and the opportunities for contact with it are equally
important. A weakly sensitising substance which is widely distributed can be a more

The material may cause severe skin irritation after prolonged or repeated exposure and
may produce on contact skin redness, swelling, the production of vesicles, scaling and
thickening of the skin. Repeated exposures may produce severe ulceration.
The substance is classified by IARC as Group 3:
NOT classifiable as to its carcinogenicity to humans.
Evidence of carcinogenicity may be inadequate or limited in animal testing.

Refer to data for ingredients, which follows:
HYDROQUINONE:
Environmental toxicity is a function of the n-octanol/ water partition coefficient (log
Pow, log Kow). Phenols with log Pow >7.4 are expected to exhibit low toxicity to aquatic
organisms. However the toxicity of phenols with a lower log Pow is variable, ranging from
low toxicity (LC50 values >100 mg/l) to highly toxic (LC50 values <1 mg/l) dependent on
log Pow, molecular weight and substitutions on the aromatic ring. Dinitrophenols are more
toxic than predicted from QSAR estimates. Hazard information for these groups is not
generally available.
Do NOT allow product to come in contact with surface waters or to intertidal areas below
the mean high water mark. Do not contaminate water when cleaning equipment or disposing
of equipment wash-waters.
Wastes resulting from use of the product must be disposed of on site or at approved waste
sites.
DO NOT discharge into sewer or waterways.
The material is classified as an ecotoxin* because the Fish LC50 (96 hours) is less than
or equal to 0.1 mg/l
* Classification of Substances as Ecotoxic (Dangerous to the Environment)
