Section 4 - FIRST AID MEASURES

15 minutes from a hospital or unless instructed otherwise:
路 INDUCE vomiting with fingers down the back of the throat, ONLY IF CONSCIOUS. Lean
patient forward or place on left side (head-down position, if possible) to maintain open
airway and prevent aspiration.
NOTE: Wear a protective glove when inducing vomiting by mechanical means.

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 highly alkaline materials:
路 Respiratory stress is uncommon but present occasionally because of soft tissue edema.
路 Unless endotracheal intubation can be accomplished under direct vision,
cricothyroidotomy or tracheotomy may be necessary.
路 Oxygen is given as indicated.
路 The presence of shock suggests perforation and mandates an intravenous line and fluid
administration.
路 Damage due to alkaline corrosives occurs by liquefaction necrosis whereby the
saponification of fats and solubilisation of proteins allow deep penetration into the
tissue.
Alkalis continue to cause damage after exposure.

INGESTION:
路 Milk and water are the preferred diluents
No more than 2 glasses of water should be given to an adult.
路 Neutralising agents should never be given since exothermic heat reaction may compound
injury.
* Catharsis and emesis are absolutely contra-indicated.
* Activated charcoal does not absorb alkali.
* Gastric lavage should not be used.

Supportive care involves the following:
路 Withhold oral feedings initially.
路 If endoscopy confirms transmucosal injury start steroids only within the first 48
hours.
路 Carefully evaluate the amount of tissue necrosis before assessing the need for surgical
intervention.
路 Patients should be instructed to seek medical attention whenever they develop
difficulty in swallowing (dysphagia).

Odour Safety Factor (OSF) is determined to fall into either Class C, D or E.
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

(TLV- TWA for example) is
being reached, even when
distracted by working
activities
B 26- 550 As " A" for 50- 90% of persons

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

.

MATERIAL DATA
Odour Threshold: 2.6 ppm
The TLV-TWA is thought to be protective against the significant risk of
eye damage and skin irritation.

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
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.

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION

Wear chemical protective gloves, eg. PVC.
Wear safety footwear or safety gumboots, eg. Rubber.
NOTE: The material may produce skin sensitisation in predisposed individuals. Care must
be taken, when removing gloves and other protective equipment, to avoid all possible skin
contact.

OTHER
路 Overalls.
路 P.V.C. apron.
路 Barrier cream.
路 Skin cleansing cream.
路 Eye wash unit.

The local concentration of material, quantity and conditions of use determine the type of
personal protective equipment required.
For further information consult site specific
CHEMWATCH data (if available), or your
Occupational Health and Safety Advisor.

ENGINEERING CONTROLS
General exhaust is adequate under normal operating conditions. Local exhaust ventilation
may be required in special circumstances. If risk of overexposure exists, wear approved
respirator. Supplied-air type respirator may be required in special circumstances.
Correct fit is essential to ensure adequate protection. Provide adequate ventilation in
warehouses and enclosed 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 1- 2.5 m/s (200- 500 f/min.)
booths, 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.

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.

EYE
If applied to the eyes, this material causes severe eye damage.

SKIN
Skin contact with the material may damage the health of the individual; systemic effects
may result following absorption.
The material may cause mild but significant 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.
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
The material can cause respiratory irritation in some persons. The body's response to
such irritation can cause further lung damage.
The material is not thought to produce adverse health effects following inhalation (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 and that suitable control
measures be used in an occupational setting.
Not normally a hazard due to non-volatile nature of product.

CHRONIC HEALTH EFFECTS
There has been some concern that this material can cause cancer or mutations but there is
not enough data to make an assessment.
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 mucous production.
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.
Harmful: danger of serious damage to health
by prolonged exposure if swallowed.
This material can cause serious damage if one is exposed to it for long periods. It can
be assumed that it contains a substance which can produce severe defects. This has been
demonstrated via both short- and long-term experimentation.
Prolonged or chronic exposure to alkanolamines may result in liver, kidney or nervous
system injury. Repeated inhalation may aggravate asthma and lung disease involving
inflammation or scarring.
Results of animal testing with diethanolamine (DEA) and monoethanolamine (MEA) has shown
a wide range of possible effects, including induction of tumours, developmental
abnormalities and injury to the foetus and mother.
Many amines greatly sensitise the skin and respiratory system, and certain individuals,
especially those predisposed to asthma and other allergic responses, may show allergic
reactions when chronically exposed to alkanolamines.
