路 If vomiting occurs, lean patient forward or place on left side (head-down position, if
possible) to maintain open airway and prevent aspiration.
路 Observe the patient carefully.
路 Never give liquid to a person showing signs of being sleepy or with reduced awareness;
i.e. becoming unconscious
路 Give water to rinse out mouth, then provide liquid slowly and as much as casualty can
comfortably drink.
路 Seek medical advice.
EYE
If this product comes in contact with the eyes:
路 Immediately hold eyelids apart and flush the eye continuously with running water.
路 Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and
moving the eyelids by occasionally lifting the upper and lower lids.

Section 4 - FIRST AID MEASURES
路 Transport to hospital or doctor without delay.
路 Removal of contact lenses after an eye injury should only be undertaken by skilled
personnel.
SKIN
If skin or hair contact occurs:
路 Immediately flush body and clothes with large amounts of water, using safety shower if
available.
路 Quickly remove all contaminated clothing, including footwear.
路 Wash skin and hair with running water. Continue flushing with water until advised to
stop by the Poisons Information Centre.
路 Transport to hospital, or doctor.
INHALED
路 If fumes or combustion products are inhaled remove from contaminated area.
路 Lay patient down. Keep warm and rested.
路 Prostheses such as false teeth, which may block airway, should be removed, where
possible, prior to initiating first aid procedures.
路 Apply artificial respiration if not breathing, preferably with a demand valve
resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary.
路 Transport to hospital, or doctor, without delay.
NOTES TO PHYSICIAN
For acute or short term repeated exposures to strong acids:
路 Airway problems may arise from laryngeal edema and inhalation exposure. Treat with 100%
oxygen initially.
路 Respiratory distress may require cricothyroidotomy if endotracheal intubation is
contraindicated by excessive swelling
路 Intravenous lines should be established immediately in all cases where there is
evidence of circulatory compromise.
路 Strong acids produce a coagulation necrosis characterised by formation of a coagulum
(eschar) as a result of the dessicating action of the acid on proteins in specific
tissues.
INGESTION:
路 Immediate dilution (milk or water) within 30 minutes post ingestion is recommended.
路 DO NOT attempt to neutralise the acid since exothermic reaction may extend the
corrosive injury.
路 Be careful to avoid further vomit since re-exposure of the mucosa to the acid is
harmful. Limit fluids to one or two glasses in an adult.
路 Charcoal has no place in acid management.
路 Some authors suggest the use of lavage within 1 hour of ingestion.
SKIN:
路 Skin lesions require copious saline irrigation. Treat chemical burns as thermal burns
with non-adherent gauze and wrapping.
路 Deep second-degree burns may benefit from topical silver sulfadiazine.
EYE:
路 Eye injuries require retraction of the eyelids to ensure thorough irrigation of the
conjuctival cul-de-sacs. Irrigation should last at least 20-30 minutes. DO NOT use
neutralising agents or any other additives. Several litres of saline are required.
路 Cycloplegic drops, (1% cyclopentolate for short-term use or 5% homatropine for longer
term use) antibiotic drops, vasoconstrictive agents or artificial tears may be indicated
dependent on the severity of the injury.
路 Steroid eye drops should only be administered with the approval of a consulting
ophthalmologist).

Section 5 - FIRE FIGHTING MEASURES
EXTINGUISHING MEDIA
路 Water spray or fog.
路 Foam.
路 Dry chemical powder.
路 BCF (where regulations permit).
路 Carbon dioxide.
FIRE FIGHTING
Alert Fire Brigade and tell them location and nature of hazard.
路 Wear full body protective clothing with breathing apparatus.
路 Prevent, by any means available, spillage from entering drains or water courses.
Cool fire exposed containers with water spray from a protected location.
DO NOT approach containers suspected to be hot.
If safe to do so, remove containers from path of fire.
FIRE/EXPLOSION HAZARD
路 Combustible.
路 Slight fire hazard when exposed to heat or flame.
路 Heating may cause expansion or decomposition leading to violent rupture of containers.
路 On combustion, may emit toxic fumes of carbon monoxide (CO).
路 May emit acrid smoke.
路 Mists containing combustible materials may be explosive.
Other combustion products include:
acrolein.
路 Hot organic vapours or mist are capable of sudden spontaneous combustion when mixed
with air even at temperatures below their published autoignition temperatures.
路 The temperature of ignition decreases with increasing vapour volume and vapour/air
contact times and is influenced by pressure change.
路 Ignition may occur under elevated-temperature process conditions especially in
processes performed under vacuum subjected to sudden ingress of air or in processes
performed at elevated pressure, where sudden escape of vapours or mists to the
atmosphere occurs.
FIRE INCOMPATIBILITY
Unstable under normal storage conditions, requires controlled
conditions for stability.
Avoid contamination with oxidising agents, strong acids, peroxides, persulfates,
polymerisation catalyst, alkalies, amines, metal salts. Polymerisation with exotherm
may result from contamination.

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.

Section 10 - CHEMICAL STABILITY AND REACTIVITY INFORMATION
CONDITIONS CONTRIBUTING TO INSTABILITY
Unstable under normal storage conditions, requires controlled
conditions for stability.
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.

Based on the available oncogenicity data and without a better understanding of the
carcinogenic mechanism the Health and Environmental Review Division (HERD), Office of
Toxic Substances (OTS), of the US EPA previously concluded that all chemicals that
contain the acrylate or methacrylate moiety (CH2=CHCOO or CH2=C(CH3)COO) should be
considered to be a carcinogenic hazard unless shown otherwise by adequate testing.
This position has now been revised and acrylates and methacrylates are no longer de facto
carcinogens.
