Section 4 - FIRST AID MEASURES
SWALLOWED
路 For advice, contact a Poisons Information Centre or a doctor at once.
路 Urgent hospital treatment is likely to be needed.
路 If swallowed do NOT induce vomiting.
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 Transport to hospital or doctor without delay.
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.
路 Continue flushing until advised to stop by the Poisons Information Centre or a doctor,
or for at least 15 minutes.
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

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 6 - ACCIDENTAL RELEASE MEASURES
Personal Protective Equipment advice is contained in Section 8 of the MSDS.
Section 7 - HANDLING AND STORAGE
PROCEDURE FOR HANDLING
DO NOT allow clothing wet with material to stay in contact with skin.
The substance is a peroxidisable vinyl monomer that may exothermically polymerise as a
result of decomposition of accumulated peroxides; that is, the peroxides initiate very
energetic polymerisation of the bulk monomer
Purchases of peroxidisable chemicals should be restricted to ensure that the chemical is
used completely before it can become peroxidised.
路 A responsible person should maintain an inventory of peroxidisable chemicals or
annotate the general chemical inventory to indicate which chemicals are subject to
peroxidation. An expiration date should be determined. The chemical should either be
treated to remove peroxides or disposed of before this date.
路 The person or laboratory receiving the chemical should record a receipt date on the
bottle. The individual opening the container should add an opening date.
路 Unopened containers received from the supplier should be safe to store for 18 months.
路 Opened containers of inhibited material should not be stored for more than 12 months;
they should NOT be stored under an inert atmosphere. Generally, storage of inhibited
vinyl monomers should be under air rather than nitrogen or other inert atmosphere,
because customary inhibitors are phenolic compounds, which require oxygen for their
action. Most vinyl monomers may be polymerized without removal of inhibitor by proper
adjustment of initiator concentration, thus making the isolation of the more hazardous
uninhibited material unnecessary.
路 Opened containers of uninhibited material (>500 g) should not be stored for more than
24 hours; small samples (less than 10 g) may be stored longer than 24 hours with
discretion. Generally storage of uninhibited vinyl monomers should be under nitrogen and
below room temperatures. For storage in excess of 24 hours, a suitable inhibitor should
be added, and its name and quantity should be placed on the label.
路 Avoid all personal contact, including inhalation.
路 Wear protective clothing when risk of exposure occurs.
路 Use in a well-ventilated area.
路 WARNING: To avoid violent reaction, ALWAYS add material to water and NEVER water to
material.
路 Avoid smoking, naked lights or ignition sources.
路 Avoid contact with incompatible materials.
路 When handling, DO NOT eat, drink or smoke.
路 Keep containers securely sealed when not in use.
路 Avoid physical damage to containers.
路 Always wash hands with soap and water after handling.
路 Work clothes should be laundered separately. Launder contaminated clothing before re
-use.
路 Use good occupational work practice.
路 Observe manufacturer's storing and handling recommendations.
路 Atmosphere should be regularly checked against established exposure standards to
ensure safe working conditions are maintained.
路 Containers, even those that have been emptied, may contain explosive vapours.
路 Do NOT cut, drill, grind, weld or perform similar operations on or near containers.
SUITABLE CONTAINER
路 Lined metal can. Lined metal drum. Lined metal safety cans.
路 Packing as supplied and/or recommended by manufacturer.
路 Plastic lining or containers may only be used if approved for flammable liquid
(non-polar type).
路 Check that containers are clearly labelled and free from leaks.
DO NOT use aluminium or galvanised containers.

路 Removable head packaging;
路 Cans with friction closures and
路 low pressure tubes and cartridges
may be used.
-
Where combination packages are used, and the inner packages are of glass, porcelain or

outer packages unless the outer packaging is a close fitting moulded plastic box and the
substances are not incompatible with the plastic.
路 Lined metal can, lined metal pail/ can.
路 Plastic pail.
路 Polyliner drum.
路 Packing as recommended by manufacturer.
路 Check all containers are clearly labelled and free from leaks.
STORAGE INCOMPATIBILITY
Reacts with mild steel, galvanised steel / zinc producing hydrogen gas which may form an
explosive mixture with air.
Avoid strong bases.
Segregate from alkalies, oxidising agents and chemicals readily decomposed by acids, i.e.
cyanides, sulfides, carbonates.
STORAGE REQUIREMENTS
路 Store in approved flammable liquid storage area.
路 No smoking, naked lights/ignition sources.
路 Keep containers securely sealed.
路 Store away from incompatible materials in a cool, dry, well-ventilated area.
路 Protect containers against physical damage and check regularly for leaks.
路 Observe manufacturer's storing and handling recommendations.
Easily peroxidisable. Products formed as a result of peroxidation are not only safety
hazards but may chemically alter the chemical behavior of the parent compound.
Should have a warning label affixed bearing the date of receipt in the laboratory and the
date on which the container label is first opened, or laboratory synthesised materials
are the responsibility of the individual chemist.
WARNING:This product may form peroxides which themselves are not themselves particularly
hazardous but which on decomposition may initiate explosive polymerisation of the bulk
monomer (Trommsdorf effect). Should be evaluated every 12 months, redated if safe or else
discarded. Quantities of uninhibited monomers exceeding 500 ml should not be stored for
more than 24 hours.
The oxidation of iodide to iodine or the conversion of colourless ferrothiocyanate to red
ferrithiocyanate by peroxides are simple and convenient tests for most peroxides.
Before distilling or evaporating a suitable polymerisation inhibitor should be added.
Leave at least 10% bottoms. Use a shield when evaporating or distilling mixtures which
may contain peroxidisable compounds. Store away from heat and light. Particular attention
should be paid to the adequacy of the closure on storage containers.
Peroxides may be removed by;
路 passing the material over a column of ordinary activated alumina (care should be taken
in disposal of the activated alumina);
路 shaking with a concentrated solution of ferrous salt (provided the carrier solvent is
water-insoluble);
路 agitation with an approximately equimolar mixture of ferrous sulfate and sodium

When solvents have been freed from peroxides by percolation through a column of activated
alumina, the adsorbed peroxides must promptly be desorbed by treatment with polar
solvents, methanol or water, which must in turn be discarded safely.***.
路 Storage requires stabilising inhibitor content and dissolved oxygen content to be
monitored. Refer to manufacturer's recommended levels.
路 DO NOT overfill containers so as to maintain free head space above product.

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
NIOSH Current Intelligence Bulletin 59].
HANDS/FEET
Suitability and durability of glove type is dependent on usage. Factors such as:
路 frequency and duration of contact,
路 chemical resistance of glove material,
路 glove thickness and
路 dexterity,
are important in the selection of gloves.
Elbow length PVC gloves.
When handling corrosive liquids, wear trousers or overalls outside of boots, to avoid
spills entering boots.

* Where the glove is to be used on a short term, casual or infrequent basis,
factors such as "feel" or convenience (e.g. disposability), may dictate a choice
of gloves which might otherwise be unsuitable following long-term or frequent use.
A qualified practitioner should be consulted.
RESPIRATOR
Selection of the Class and Type of respirator will depend upon the level of breathing
zone contaminant and the chemical nature of the contaminant. Protection Factors (defined
as the ratio of contaminant outside and inside the mask) may also be important.

ENGINEERING CONTROLS
Local exhaust ventilation usually required. If risk of overexposure exists, wear approved
respirator. Correct fit is essential to obtain adequate protection. Supplied-air type
respirator may be required in special circumstances. Correct fit is essential to ensure
adequate protection.
An approved self contained breathing apparatus (SCBA) may be required in some situations.
Provide adequate ventilation in warehouse or closed storage area. 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.

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.

Section 10 - CHEMICAL STABILITY AND REACTIVITY INFORMATION
CONDITIONS CONTRIBUTING TO INSTABILITY
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 with alkaline material liberates heat.
Section 11 - TOXICOLOGICAL INFORMATION
POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED
Accidental ingestion of the material may be harmful; animal experiments indicate that
ingestion of less than 150 gram may be fatal or may produce serious damage to the health
of the individual.
Ingestion of acidic corrosives may produce burns around and in the mouth, the throat and
oesophagus. Immediate pain and difficulties in swallowing and speaking may also be
evident. Swelling of the epiglottis may make it difficult to breathe which may result in
suffocation. More severe exposure may result in vomiting blood and thick mucus, shock,
abnormally low blood pressure, fluctuating pulse, shallow respiration and clammy skin,
inflammation of stomach wall, and rupture of oesophageal tissue. Untreated shock may
eventually result in kidney failure. Severe cases may result in perforation of the
stomach and abdominal cavity with consequent infection, rigidity and fever. There may be
severe narrowing of the oesophageal or pyloric sphincters; this may occur immediately or
after a delay of weeks to years. There may be coma and convulsions, followed by death due
to infection of the abdominal cavity, kidneys or lungs.
EYE
If applied to the eyes, this material causes severe eye damage.
Direct eye contact with acid corrosives may produce pain, tears, sensitivity to light and
burns. Mild burns of the epithelia generally recover rapidly and completely. Severe burns
produce long-lasting and possibly irreversible damage. The appearance of the burn may not
be apparent for several weeks after the initial contact. The cornea may ultimately become
deeply opaque resulting in blindness.
SKIN
Skin contact with the material may be harmful; systemic effects may result following
absorption.

Section 11 - TOXICOLOGICAL INFORMATION
The material may cause moderate inflammation of the skin either following direct contact
or after a delay of some time. Repeated exposure can cause contact dermatitis which is
characterised by redness, swelling and blistering.
Skin contact with acidic corrosives may result in pain and burns; these may be deep with
distinct edges and may heal slowly with the formation of scar tissue.
Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may
produce systemic injury with harmful effects. Examine the skin prior to the use of the
material and ensure that any external damage is suitably protected.
INHALED
Inhalation of vapours or aerosols (mists, fumes), generated by the material during the
course of normal handling, may be harmful.
The material can cause respiratory irritation in some persons. The body's response to
such irritation can cause further lung damage.
Corrosive acids can cause irritation of the respiratory tract, with coughing, choking and
mucous membrane damage. There may be dizziness, headache, nausea and weakness. Swelling
of the lungs can occur, either immediately or after a delay; symptoms of this include
chest tightness, shortness of breath, frothy phlegm and cyanosis. Lack of oxygen can
cause death hours after onset.
CHRONIC HEALTH EFFECTS
Repeated or prolonged exposure to acids may result in the erosion of teeth, swelling
and/or ulceration of mouth lining. Irritation of airways to lung, with cough, and
inflammation of lung tissue often occurs. Chronic exposure may inflame the skin or
conjunctiva.
There has been some concern that this material can cause cancer or mutations but there is
not enough data to make an assessment.
Substance accumulation, in the human body, may occur and may cause some concern following
repeated or long-term occupational exposure.
There is limited evidence that, skin contact with this product is more likely to cause a
sensitisation reaction in some persons compared to the general population.
There is some evidence from animal testing that exposure to this material may result in
toxic effects to the unborn baby.
TOXICITY AND IRRITATION
unless otherwise specified data extracted from RTECS - Register of Toxic Effects of Chemical Substances.
TOXICITY IRRITATION
Inhalation (Rat) LC: 4000 ppm/4h
Intraperitoneal (Rat) LD50: 22 mg/kg
Oral (Mouse) LD50: 2400 mg/kg

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.
Asthma-like symptoms may continue for months or even years after exposure to the material
ceases. This may be due to a non-allergenic condition known as reactive airways
dysfunction syndrome (RADS) which can occur following exposure to high levels of highly
irritating compound. Key criteria for the diagnosis of RADS include the absence of
preceding respiratory disease, in a non-atopic individual, with abrupt onset of
persistent asthma-like symptoms within minutes to hours of a documented exposure to the
irritant. A reversible airflow pattern, on spirometry, with the presence of moderate to
severe bronchial hyperreactivity on methacholine challenge testing and the lack of
minimal lymphocytic inflammation, without eosinophilia, have also been included in the
criteria for diagnosis of RADS. RADS (or asthma) following an irritating inhalation is an
infrequent disorder with rates related to the concentration of and duration of exposure
to the irritating substance. Industrial bronchitis, on the other hand, is a disorder that
occurs as result of exposure due to high concentrations of irritating substance (often
particulate in nature) and is completely reversible after exposure ceases. The disorder
is characterised by dyspnea, cough and mucus production.
