Section 4 - FIRST AID MEASURES
SWALLOWED
For advice, contact a Poisons Information Centre or a doctor.
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 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.
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 contact occurs:
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, without delay.
NOTES TO PHYSICIAN
For acute or short term repeated exposures to petroleum distillates or related
hydrocarbons:
路 Primary threat to life, from pure petroleum distillate ingestion and/or inhalation, is
respiratory failure.
路 Patients should be quickly evaluated for signs of respiratory distress (e.g. cyanosis,
tachypnoea, intercostal retraction, obtundation) and given oxygen. Patients with
inadequate tidal volumes or poor arterial blood gases (pO2 50 mm Hg) should be intubated.
路 Arrhythmias complicate some hydrocarbon ingestion and/or inhalation and
electrocardiographic evidence of myocardial injury has been reported; intravenous lines
and cardiac monitors should be established in obviously symptomatic patients. The lungs
excrete inhaled solvents, so that hyperventilation improves clearance.
路 A chest x-ray should be taken immediately after stabilisation of breathing and
circulation to document aspiration and detect the presence of pneumothorax.
路 Epinephrine (adrenalin) is not recommended for treatment of bronchospasm because of
potential myocardial sensitisation to catecholamines. Inhaled cardioselective
bronchodilators (e.g. Alupent, Salbutamol) are the preferred agents, with aminophylline a
second choice.
路 Lavage is indicated in patients who require decontamination; ensure use of cuffed

"endothermic" i.e. heat is absorbed into the compound, rather than released from it,
during its formation.
路 The majority of endothermic compounds are thermodynamically unstable and may decompose
explosively under various circumstances of initiation.
路 Many but not all endothermic compounds have been involved in decompositions, reactions
and explosions and, in general, compounds with significantly positive values of standard
heats of formation, may be considered suspect on stability grounds.

PERSONAL PROTECTION
EYE
路 Safety glasses with side shields; or as required,
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
removed in a clean environment only after workers have washed hands thoroughly. [CDC

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
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.
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.

Section 12 - ECOLOGICAL INFORMATION
Refer to data for ingredients, which follows:
4-TERT-BUTYLCATECHOL:
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 discharge into sewer or waterways.
Section 13 - DISPOSAL CONSIDERATIONS
路 Consult manufacturer for recycling options and recycle where possible .
路 Consult State Land Waste Management Authority for disposal.
