EYE
If aerosols come in contact with the eyes:
?Immediately hold the eyelids apart and flush the eye continuously for at least 15
minutes with fresh running water.
?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.
?Transport to hospital or doctor without delay.
?Removal of contact lenses after an eye injury should only be undertaken by skilled
personnel.
SKIN
If solids or aerosol mists are deposited upon the skin:
?Flush skin and hair with running water (and soap if available).
?Remove any adhering solids with industrial skin cleansing cream.
?DO NOT use solvents.
?Seek medical attention in the event of irritation.
INHALED
If aerosols, fumes or combustion products are inhaled:
?Remove to fresh air.
?Lay patient down. Keep warm and rested.
?Prostheses such as false teeth, which may block airway, should be removed, where
possible, prior to initiating first aid procedures.
?If breathing is shallow or has stopped, ensure clear airway and apply resuscitation,
preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as
trained. Perform CPR if necessary.
?Transport to hospital, or doctor.
NOTES TO PHYSICIAN

gastrointestinal tracts.
?Conjunctival irritation, skin inflammation (erythema, pain vesiculation) and
gastrointestinal disturbances occur soon after exposure.
?Pulmonary symptoms include cough, burning, substernal pain and dyspnoea.
?Some cross-sensitivity occurs between different isocyanates.
?Noncardiogenic pulmonary edema and bronchospasm are the most serious consequences of
exposure. Markedly symptomatic patients should receive oxygen, ventilatory support and an
intravenous line.
?Treatment for asthma includes inhaled sympathomimetics (epinephrine [adrenalin],
terbutaline) and steroids.
?Activated charcoal (1 g/kg) and a cathartic (sorbitol, magnesium citrate) may be useful
for ingestion.
?Mydriatics, systemic analgesics and topical antibiotics (Sulamyd) may be used for
corneal abrasions.
?There is no effective therapy for sensitised workers.
[Ellenhorn and Barceloux; Medical Toxicology]
NOTE: Isocyanates cause airway restriction in naive individuals with the degree of
response dependant on the concentration and duration of exposure. They induce smooth
muscle contraction which leads to bronchoconstrictive episodes. Acute changes in lung
function, such as decreased FEV1, may not represent sensitivity.

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

INGREDIENT DATA
MDI OLIGOMER:
Some jurisdictions require that health surveillance be conducted on occupationally
exposed workers. This should emphasise:
?demography, occupational and medical history and health advice
?completion of a standardised respiratory questionnaire
?physical examination of the respiratory system and skin
?standardised respiratory function tests such as FEV1, FVC and FEV1/FVC.
TRIS(2-CHLOROISOPROPYL)PHOSPHATE:
No exposure limits set by NOHSC or ACGIH.
TETRAFLUOROETHANE:
Sensory irritants are chemicals that produce temporary and undesirable side-effects on
the eyes, nose or throat. Historically occupational exposure standards for these
irritants have been based on observation of workers' responses to various airborne
concentrations. Present day expectations require that nearly every individual should be
protected against even minor sensory irritation and exposure standards are established
using uncertainty factors or safety factors of 5 to 10 or more. On occasion animal no
-observable-effect-levels (NOEL) are used to determine these limits where human results
are unavailable. An additional approach, typically used by the TLV committee (USA) in
determining respiratory standards for this group of chemicals, has been to assign ceiling
values (TLV C) to rapidly acting irritants and to assign short-term exposure limits (TLV
STELs) when the weight of evidence from irritation, bioaccumulation and other endpoints

combine to warrant such a limit. In contrast the MAK Commission (Germany) uses a five
-category system based on intensive odour, local irritation, and elimination half-life.
However this system is being replaced to be consistent with the European Union (EU)
Scientific Committee for Occupational Exposure Limits (SCOEL); this is more closely
allied to that of the USA.
OSHA (USA) concluded that exposure to sensory irritants can:
?cause inflammation
?cause increased susceptibility to other irritants and infectious agents
?lead to permanent injury or dysfunction
?permit greater absorption of hazardous substances and
?acclimate the worker to the irritant warning properties of these substances thus
increasing the risk of overexposure.
Studies show that HFC 134a is practically nontoxic by inhalation. The
acute lethal effects occur at levels exceeding 500000 ppm whilst the
threshold for cardiac sensitisation occurs at about 75000 ppm. Repeated
exposures at 50000 ppm for 13 weeks did not produce significant toxicity
in animals. Limited studies have shown the substance not to be a
carcinogen, or to exhibit mutagenic effects. Exposures up to 300000 ppm
and 40000 ppm did not produce teratogenic effects in rats and rabbits
respectively. The workplace environmental exposure level (WEEL),
recommended by the AIHA, is thought to be protective against cardiac
sensitisation and systemic injury.
DIMETHYL ETHER:
The no-effect-level for dimethyl ether is somewhere between 2000 ppm
(rabbits) and 50,000 ppm (humans) with possible cardiac sensitisation
occurring around 200,000 ppm (dogs). The AIHA has adopted a safety factor
of 100 in respect to the 50,000 ppm level in its recommendation for a
workplace environmental exposure level (WEEL) which is thought to protect
against both narcotic and sensitising effects. This level is consistent
with the TLV-TWA of 400 ppm for diethyl ether and should be easily
achievable using current technologies. The use of the traditionally
allowable excursion of 1.25 to the level of 6.25 ppm is felt to be more
than adequate as an upper safe limit of exposure.
Human data:
50,000 ppm (12 mins): Feelings of mild intoxication.
75,000 ppm (12 mins): As above plus slight lack of attenuation.
82,000 ppm (12 mins): Some incoordination, slight blurring of vision
(30 mins): As above plus analgesia of the face and rushing of
blood to the face.
100,000 ppm (10-20 mins): Narcotic symptoms

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

HANDS/FEET
No special equipment needed when handling small quantities.
OTHERWISE:
For potentially moderate exposures:
Wear general protective gloves, eg. light weight rubber gloves.
For potentially heavy exposures:
Wear chemical protective gloves, eg. PVC. and safety footwear.
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.

ENGINEERING CONTROLS
General exhaust is adequate under normal conditions. If risk of overexposure exists, wear
SAA approved respirator. Correct fit is essential to obtain adequate protection.
Provide adequate ventilation in warehouse or closed 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.

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
Not normally a hazard due to physical form of product.
Considered an unlikely route of entry in commercial/industrial environments.
Ingestion may result in nausea, abdominal irritation, pain and vomiting.
EYE
The material may be irritating to the eye, with prolonged contact causing inflammation.
Repeated or prolonged exposure to irritants may produce conjunctivitis.
Eye contact with alkyl ethers (vapour or liquid) may produce irritation,
redness and tears.
SKIN
The material may accentuate any pre-existing dermatitis condition.
Spray mist may produce discomfort.
Fluorocarbons remove natural oils from the skin, causing irritation,
dryness and sensitivity.
Alkyl ethers may defat and dehydrate the skin producing dermatoses. Absorption may
produce headache, dizziness, and central nervous system depression.
INHALED
Inhalation of aerosols (mists, fumes), generated by the material during the course of
normal handling, may be harmful.
Material is highly volatile and may quickly form a concentrated atmosphere in confined or
unventilated areas. Vapour is heavier than air and may displace and replace air in
breathing zone, acting as a simple asphyxiant. This may happen with little warning of
overexposure.
WARNING:Intentional misuse by concentrating/inhaling contents may be lethal.
CHRONIC HEALTH EFFECTS
Principal routes of exposure are by accidental skin and eye contact and by inhalation of
vapours especially at higher temperatures.
Persons with a history of asthma or other respiratory problems or are known to be
sensitised, should not be engaged in any work involving the handling of isocyanates.
[CCTRADE-Bayer, APMF].
Animal testing shows that polymeric MDI can damage the nasal cavities and lungs, causing

persons compared to the general population.
Respiratory sensitisation may result in allergic/asthma like responses; from coughing and
minor breathing difficulties to bronchitis with wheezing, gasping.
Sensitisation may result in allergic dermatitis responses including rash, itching, hives
or swelling of extremities.
Isocyanate vapours are irritating to the airways and can cause their inflammation, with
wheezing, gasping, severe distress, even loss of consciousness and fluid in the lungs.
Nervous system symptoms that may occur include headache, sleep disturbance, euphoria,
inco-ordination, anxiety, depression and paranoia. Digestive effects include nausea and
vomiting. Breathing difficulties may occur unpredictably after a period of tolerance and
after skin contact. Allergic inflammation of the skin can occur, with rash, itching,
blistering, and swelling of the hands and feet. Sensitive people can react to very low
levels and should not be exposed to this material.

TETRAFLUOROETHANE:
In addition to carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), the
greenhouse gases mentioned in the Kyoto Protocol include synthetic substances that share
the common feature of being highly persistent in the atmosphere and exhibiting very high
specific radiative forcing (radiative forcing is the change in the balance between
radiation coming into the atmosphere and radiation out; a positive radiative forcing
tends on average to warm the surface of the earth). These synthetic substances include
hydrocarbons that are partially fluorinated (HCFs) or totally fluorinated (PFCs) as well
as sulfur hexafluoride (SF6).
The greenhouse potential of these substances, expressed as multiples of that of CO2, are
within the range of 140 to 11,700 for HFCs, from 6500 to 9,200 for PFCs and 23,900 for
SF6. Once emitted into the atmosphere, these substances have an impact on the environment
for decades, centuries, or in certain instances, for thousands of years.
Many of these substances have only been commercialised for a few years, and still only
contribute only a small percentage of those gases released to the atmosphere by humans
(anthropogenic) which increase the greenhouse effect. However, a rapid increase can be
seen in their consumption and emission, and therefore in their contribution to the
anthropogenic increase in the greenhouse effect.
Since the adoption of the Kyoto Protocol, new fluorinated substances have appeared on the
market, which are stable in air and have a high greenhouse potential; these include
nitrogen trifluoride (NF3) and fluoroethers.
Persistence and Degradation:
Ozone Destruction Potential PDO) = 0 (R11=1)
Greenhouse Effect Potential (ESP) = 0.27 (R11=1)
Decomposed comparatively rapidly in the lower atmosphere (troposphere).
Atmospheric lifetime is 15.6 years. Products of decomposition will be
highly dispersed and hence will have a very low concentration. Does not
influence photochemical smog (i.e. is not a VOC under the terms of the
