Section 4 - FIRST AID MEASURES
SWALLOWED
If spontaneous vomiting appears imminent or occurs, hold patient's head down, lower than
their hips to help avoid possible aspiration of vomitus.
路 Immediately give a glass of water.
路 First aid is not generally required. If in doubt, contact a Poisons Information Centre
or a doctor.
EYE
If this product comes in contact with the eyes:
路 Wash out immediately with fresh 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 If pain persists or recurs seek medical attention.
路 Removal of contact lenses after an eye injury should only be undertaken by skilled
personnel.

Section 4 - FIRST AID MEASURES
路 Immediately remove all contaminated clothing, including footwear.
路 Flush skin and hair with running water (and soap if available).
路 Seek medical attention in event of irritation.
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.
NOTES TO PHYSICIAN
Treat symptomatically.
Any material aspirated during vomiting may produce lung injury. Therefore emesis should
not be induced mechanically or pharmacologically. Mechanical means should be used if it
is considered necessary to evacuate the stomach contents; these include gastric lavage
after endotracheal intubation. If spontaneous vomiting has occurred after ingestion, the
patient should be monitored for difficult breathing, as adverse effects of aspiration
into the lungs may be delayed up to 48 hours.
for simple esters:
--------------------------------------------------------------
BASIC TREATMENT
--------------------------------------------------------------
路 Establish a patent airway with suction where necessary.
路 Watch for signs of respiratory insufficiency and assist ventilation as necessary.
路 Administer oxygen by non-rebreather mask at 10 to 15 l/min.
路 Monitor and treat, where necessary, for pulmonary oedema .
路 Monitor and treat, where necessary, for shock.
路 DO NOT use emetics. Where ingestion is suspected rinse mouth and give up to 200 ml
water (5 ml/kg recommended) for dilution where patient is able to swallow, has a strong
gag reflex and does not drool.
路 Give activated charcoal.
--------------------------------------------------------------
ADVANCED TREATMENT
--------------------------------------------------------------
路 Consider orotracheal or nasotracheal intubation for airway control in unconscious
patient or where respiratory arrest has occurred.
路 Positive-pressure ventilation using a bag-valve mask might be of use.
路 Monitor and treat, where necessary, for arrhythmias.
路 Start an IV D5W TKO. If signs of hypovolaemia are present use lactated Ringers
solution. Fluid overload might create complications.
路 Drug therapy should be considered for pulmonary oedema.
路 Hypotension with signs of hypovolaemia requires the cautious administration of fluids.
Fluid overload might create complications.
路 Treat seizures with diazepam.
路 Proparacaine hydrochloride should be used to assist eye irrigation.
--------------------------------------------------------------
EMERGENCY DEPARTMENT
--------------------------------------------------------------
路 Laboratory analysis of complete blood count, serum electrolytes, BUN, creatinine,
glucose, urinalysis, baseline for serum aminotransferases (ALT and AST), calcium,
phosphorus and magnesium, may assist in establishing a treatment regime. Other useful
analyses include anion and osmolar gaps, arterial blood gases (ABGs), chest radiographs
and electrocardiograph.
路 Positive end-expiratory pressure (PEEP)-assisted ventilation may be required for acute
parenchymal injury or adult respiratory distress syndrome.
路 Consult a toxicologist as necessary.

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 129 is taken from the US DOT emergency response guide book.
6 IERG information is derived from CANUTEC - Transport Canada.

ODOUR SAFETY FACTOR (OSF)
OSF=3.8E2 (n-BUTYLACETATE)
MATERIAL DATA
Exposed individuals are reasonably expected to be warned, by smell, that the Exposure
Standard is being exceeded.
Odour Safety Factor (OSF) is determined to fall into either Class A or B.
The Odour Safety Factor (OSF) is defined as:
OSF= Exposure Standard (TWA) ppm/ Odour Threshold Value (OTV) ppm
Classification into classes follows:
Class OSF Description
A 550 Over 90% of exposed individuals
are aware by smell that the
Exposure Standard (TLV- TWA for
example) is being reached, even
when distracted by working
activities
B 26- 550 As " A" for 50- 90% of persons
being distracted
C 1- 26 As " A" for less than 50% of
persons being distracted
D 0.18- 1 10- 50% of persons aware of
being tested perceive by smell
that the Exposure Standard is
being reached
E <0.18 As " D" for less than 10% of
persons aware of being tested
.
Odour Threshold Value: 0.0063 ppm (detection), 0.038-12 ppm (recognition)
Exposure at or below the recommended TLV-TWA is thought to prevent
significant irritation of the eyes and respiratory passages as well as
narcotic effects. In light of the lack of substantive evidence regarding
teratogenicity and a review of acute oral data a STEL is considered
inappropriate.
PERSONAL PROTECTION
EYE
路 Safety glasses with side shields.
路 Chemical goggles.
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

ENGINEERING CONTROLS
For flammable liquids and flammable gases, local exhaust ventilation or a process
enclosure ventilation system may be required. Ventilation equipment should be explosion
-resistant.
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)
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.

POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED
Swallowing of the liquid may cause aspiration into the lungs with the risk of chemical
pneumonitis; serious consequences may result. (ICSC13733).
The material is not thought to produce adverse health effects following ingestion (as
classified by EC Directives using animal models). Nevertheless, adverse systemic effects
have been produced following exposure of animals by at least one other route and good
hygiene practice requires that exposure be kept to a minimum.
EYE
There is some evidence that material may produce eye irritation in some persons and
produce eye damage 24 hours or more after instillation. Severe inflammation may be
expected with redness. There may be damage to the cornea. Unless treatment is prompt and
adequate there may be permanent loss of vision. Conjunctivitis can occur following
repeated exposure.
SKIN
There is some evidence to suggest that 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.

Section 11 - TOXICOLOGICAL INFORMATION
Skin contact is not thought to produce harmful health effects (as classified under EC
Directives using animal models). Systemic harm, however, has been identified following
exposure of animals by at least one other route and the material may still produce health
damage following entry through wounds, lesions or abrasions. Good hygiene practice
requires that exposure be kept to a minimum and that suitable gloves be used in an
occupational setting.
Repeated exposure may cause skin cracking, flaking or drying following normal handling
and use.
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 is not thought to produce respiratory irritation (as classified by EC
Directives using animal models). Nevertheless inhalation of vapours, fumes or aerosols,
especially for prolonged periods, may produce respiratory discomfort and occasionally,
distress.
If exposure to highly concentrated solvent atmosphere is prolonged this may lead to
narcosis, unconsciousness, even coma and possible death.
Inhalation of vapours may cause drowsiness and dizziness. This may be accompanied by
sleepiness, reduced alertness, loss of reflexes, lack of co-ordination, and vertigo.
The main effects of simple esters are irritation, stupor and insensibility. Headache,
drowsiness, dizziness, coma and behavioural changes may occur. Respiratory symptoms may
include irritation, shortness of breath, rapid breathing, throat inflammation, bronchitis
, lung inflammation and pulmonary oedema, sometimes delayed. Nausea, vomiting, diarrhoea
and cramps are observed. Liver and kidney damage may result from massive exposures.
Prolonged exposure may cause headache, nausea and ultimately loss of
consciousness.
CHRONIC HEALTH EFFECTS
Long-term exposure to the product is not thought to produce chronic effects adverse to
the health (as classified by EC Directives using animal models); nevertheless exposure by
all routes should be minimised as a matter of course.
