· If swallowed do NOT induce vomiting.
· If vomiting occurs, lean patient forward or place on left side (head-down
position, if possible) to maintain open airway and prevent aspiration.
· Observe the patient carefully.
· Never give liquid to a person showing signs of being sleepy or with reduced
awareness; i.e. becoming unconscious.
· Give water to rinse out mouth, then provide liquid slowly and as much as
casualty can comfortably drink.
· Seek medical advice.
If this product comes in contact with the eyes:
· Wash out immediately 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.
· If pain persists or recurs seek medical attention.
· Removal of contact lenses after an eye injury should only be undertaken by
skilled personnel.
If skin contact occurs:
· Immediately remove all contaminated clothing, including footwear
· Flush skin and hair with running water (and soap if available).
· Seek medical attention in event of irritation.
· If fumes or combustion products are inhaled remove from contaminated area.
· Other measures are usually unnecessary.
Treat symptomatically. For sub-chronic and chronic exposures to isocyanates: · This material may be a potent pulmonary sensitiser which causes bronchospasm even in patients without prior airway hyperreactivity. · Clinical symptoms of exposure involve mucosal irritation of respiratory and 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.

Exposure limits with "skin" notation indicate that vapour and liquid may be
absorbed through intact skin. Absorption by skin may readily exceed vapour
inhalation exposure. Symptoms for skin absorption are the same as for
inhalation. Contact with eyes and mucous membranes may also contribute to
overall exposure and may also invalidate the exposure standard.
IDLH Level: 900 ppm
Odour Threshold Value: 20 ppm (detection), 40 ppm (recognition)
NOTE: Detector tubes for o-xylene, measuring in excess of 10 ppm, are
available commercially. (m-xylene and p-xylene give almost the same
response)
Xylene vapour is an irritant to the eyes, mucous membranes and skin and
causes narcosis at high concentrations. Exposure to doses sufficiently high
to produce intoxication and unconsciousness also produces transient liver
and kidney toxicity. Neurologic impairment is NOT evident amongst
volunteers inhaling up to 400 ppm though complaints of ocular and upper
respiratory tract irritation occur at 200 ppm for 3 to 5 minutes.
Exposure to xylene at or below the recommended TLV-TWA and STEL is thought
to minimise the risk of irritant effects and to produce neither significant
narcosis or chronic injury. An earlier skin notation was deleted because
percutaneous absorption is gradual and protracted and does not
substantially contribute to the dose received by inhalation.

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

Odour Threshold Value: 0.39 ppm
IDLH Level: 75 mg/m³
Mean MDI exposures of less than 0.003 ppm appear to have no acute or
chronic effect on pulmonary function.
MDI produces identical toxicological responses to those produced by TDI
and the recommended TLV-TWA is identical for the two isocyanates. Exposure
at or below the recommended value is thought to protect the worker against
pulmonary function decrements as well as to minimise the potential for
respiratory tract sensitisation. Individuals who may be hypersusceptible
or otherwise unusually responsive to exposure to certain industrial
chemicals may not adequately protected from adverse health effects caused
by MDI at the recommended TLV-TWA. Ceiling values recommended by NIOSH
and OSHA are synonymous with normal excursions allowable for exposures to
the TLV-TWA (in excess of 3 x TLV-TWA for no more than a total of
30 minutes during a work day but in any case not exceeding 5 x TLV-TWA).
· Safety glasses with side shields · Chemical goggles. · Contact lenses pose a special hazard; soft lenses may absorb irritants and all lenses concentrate them.
Wear chemical protective gloves, eg. PVC. Wear safety footwear or safety gumboots, eg. Rubber
· Overalls. · P.V.C. apron. · Barrier cream. · Skin cleansing cream. · Eye wash unit.
Respiratory protection is required when ANY "Worst Case" vapour-phase
concentration is exceeded (see Computer Prediction in "Exposure Standards").

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.
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.

Product is considered stable and hazardous polymerisation will not occur.
The material has NOT been classified by EC Directives or other classification
systems as "harmful by ingestion". This is because of the lack of corroborating
animal or human evidence. The material may still be damaging to the health of
the individual, following ingestion, especially where pre-existing organ (e.g
liver, kidney) damage is evident. Present definitions of harmful or toxic
substances are generally based on doses producing mortality rather than those
producing morbidity (disease, ill-health). Gastrointestinal tract discomfort may
produce nausea and vomiting. In an occupational setting however, ingestion of
insignificant quantities is not thought to be cause for concern.
Although the material is not thought to be an irritant (as classified by EC
Directives), direct contact with the eye may produce transient discomfort
characterised by tearing or conjunctival redness (as with windburn).
The material is not thought to produce adverse health effects or skin irritation
following contact (as classified by EC Directives using animal models).
Nevertheless, good hygiene practice requires that exposure be kept to a minimum
and that suitable gloves be used in an occupational setting.
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.
The material is not thought to produce adverse health effects or irritation of
the respiratory tract (as classified by EC Directives using animal models).
Nevertheless, good hygiene practice requires that exposure be kept to a minimum
and that suitable control measures be used in an occupational setting.
Practical evidence shows that inhalation of the material is capable of inducing a
sensitisation reaction in a substantial number of individuals at a greater frequency than
would be expected from the response of a normal population. Pulmonary sensitisation,
resulting in hyperactive airway dysfunction and pulmonary allergy may be accompanied by
fatigue, malaise and aching. Significant symptoms of exposure may persist for extended
periods, even after exposure ceases. Symptoms can be activated by a variety of nonspecific
environmental stimuli such as automobile exhaust, perfumes and passive smoking.
Sensitisation may give severe responses to very low levels of exposure, in situations
where exposure may occur. Prolonged or repeated skin contact may cause drying with
cracking, irritation and possible dermatitis following. Chronic solvent inhalation
exposures may result in nervous system impairment and liver and blood changes. [PATTYS].
As with any chemical product, contact with unprotected bare skin; inhalation of vapour,
mist or dust in work place atmosphere; or ingestion in any form, should be avoided by
observing good occupational work practice.
