Section 4 - FIRST AID MEASURES SWALLOWED
- 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:- Immediately hold eyelids apart and flush the eye continuously with 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. - Continue flushing until advised to stop by the Poisons Information Centre or a doctor, or for at least 15 minutes. - Transport to hospital or doctor without delay. - 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. - 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. - 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. - Transport to hospital, or doctor. NOTES TO PHYSICIAN
For sub-chronic and chronic exposures to isocyanates:- This material may be a potent pulmonary sensitiser which causes bronchospasm even inpatients without prior airway hyperreactivity. - Clinical symptoms of exposure involve mucosal irritation of respiratory andgastrointestinal tracts. - Conjunctival irritation, skin inflammation (erythema, pain vesiculation) andgastrointestinal 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 ofexposure. 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 usefulfor ingestion. - Mydriatics, systemic analgesics and topical antibiotics (Sulamyd) may be used forcorneal 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 ofresponse dependant on the concentration and duration of exposure. They induce smoothmuscle contraction which leads to bronchoconstrictive episodes. Acute changes in lungfunction, such as decreased FEV1, may not represent sensitivity.

- Foam. - Dry chemical powder. - BCF (where regulations permit). - Carbon dioxide. - Water spray or fog - Large fires only. FIRE FIGHTING
Alert Fire Brigade and tell them location and nature of hazard.
Wear breathing apparatus plus protective gloves.
Prevent, by any means available, spillage from entering drains or water course.
Use water delivered as a fine spray to control fire and cool adjacent area.
Avoid spraying water onto liquid pools.
Do not approach containers suspected to be hot.
Cool fire exposed containers with water spray from a protected location.
If safe to do so, remove containers from path of fire. FIRE/EXPLOSION HAZARD
- Combustible. - Moderate fire hazard when exposed to heat or flame. - When heated to high temperatures decomposes rapidly generating vapour which pressuresand may then rupture containers with release of flammable and highly toxic isocyanatevapour. - Burns with acrid black smoke and poisonous fumes. - Combustion yields traces of highly toxic hydrogen cyanide HCN, plus toxic nitrogenoxides NOx and carbon monoxide. - Small quantities of water in contact with hot liquid may react violently withgeneration of a large volume of rapidly expanding hot sticky semi-solid foam. - Presents additional hazard when fire fighting in a confined space. - Cooling with flooding quantities of water reduces this risk. - Water spray or fog may cause frothing and should be used in large quantities. FIRE INCOMPATIBILITY
- Avoid contamination with oxidising agents i.e. nitrates, oxidising acids, chlorinebleaches, pool chlorine etc. as ignition may result. HAZCHEM: None continued.

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 therecommended value is thought to protect the worker against pulmonary function decrementsas well as to minimise the potential for respiratory tract sensitisation. Individuals whomay be hypersusceptible or otherwise unusually responsive to exposure to certainindustrial chemicals may not adequately protected from adverse health effects caused byMDI at the recommended TLV-TWA. Ceiling values recommended by NIOSH and OSHA aresynonymous with normal excursions allowable for exposures to the TLV-TWA (in excess of 3x TLV-TWA for no more than a total of 30 minutes during a work day but in any case notexceeding 5 x TLV-TWA). PERSONAL PROTECTION
- Safety glasses with side shields. - Chemical goggles. - Contact lenses may pose a special hazard; soft contact lenses may absorb andconcentrate irritants. A written policy document, describing the wearing of lens orrestrictions on use, should be created for each workplace or task. This should include areview of lens absorption and adsorption for the class of chemicals in use and an accountof injury experience. Medical and first-aid personnel should be trained in their removaland suitable equipment should be readily available. In the event of chemical exposure,begin eye irrigation immediately and remove contact lens as soon as practicable. Lensshould be removed at the first signs of eye redness or irritation - lens should beremoved in a clean environment only after workers have washed hands thoroughly. [CDCNIOSH Current Intelligence Bulletin 59]. HANDS/FEET
- 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 betaken, when removing gloves and other protective equipment, to avoid all possible skincontact. - Contaminated leather items, such as shoes, belts and watch-bands should be removed anddestroyed.

Accidental ingestion of the material may be damaging to the health of the individual. Ingestion may result in nausea, abdominal irritation, pain and vomiting.
The material may produce moderate eye irritation leading to inflammation. Repeated orprolonged exposure to irritants may produce conjunctivitis.
This material can cause inflammation of the skin oncontact in some persons. The material may accentuate any pre-existing dermatitis condition. Bare unprotected skin should not be exposed to this material. Toxic effects may result from skin absorption.
The vapour/mist may be highly irritating to the upper respiratory tract and lungs; theresponse may be severe enough to produce bronchitis and pulmonary oedema. Possibleneurological symptoms arising from isocyanate exposure include headache, insomnia,euphoria, ataxia, anxiety neurosis, depression and paranoia. Gastrointestinaldisturbances are characterised by nausea and vomiting. Pulmonary sensitisation mayproduce asthmatic reactions ranging from minor breathing difficulties to severe allergicattacks; this may occur following a single acute exposure or may develop without warningfor several hours after exposure. Sensitized people can react to very low doses, andshould not be allowed to work in situations allowing exposure to this material. Continuedexposure of sensitised persons may lead to possible long term respiratory impairment. Inhalation hazard is increased at higher temperatures. Inhalation of vapour may aggravate a pre-existing respiratory condition. CHRONIC HEALTH EFFECTS
Persons with a history of asthma or other respiratory problems or are known to besensitised, should not be engaged in any work involving the handling of isocyanates. [CCTRADE-Bayer, APMF]. Inhaling this product is more likely to cause a sensitisation reaction in some personscompared to the general population. Skin contact with the material is more likely to cause a sensitisation reaction in somepersons compared to the general population. Sensitisation may give severe responses to very low levels of exposure, i.e. hypersensitivity. Sensitised persons should not be allowed to work in situations whereexposure may occur. Isocyanate vapours are irritating to the airways and can cause their inflammation, withwheezing, 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 andvomiting. Breathing difficulties may occur unpredictably after a period of tolerance andafter 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 lowlevels and should not be exposed to this material. TOXICITY AND IRRITATION

Contact allergies quickly manifest themselves as contact eczema, more rarely as urticariaor Quincke's oedema. The pathogenesis of contact eczema involves a cell-mediated (Tlymphocytes) immune reaction of the delayed type. Other allergic skin reactions, e.g. contact urticaria, involve antibody-mediated immune reactions. The significance of thecontact allergen is not simply determined by its sensitisation potential: thedistribution of the substance and the opportunities for contact with it are equallyimportant. A weakly sensitising substance which is widely distributed can be a moreimportant allergen than one with stronger sensitising potential with which fewindividuals come into contact. From a clinical point of view, substances are noteworthyif they produce an allergic test reaction in more than 1% of the persons tested. Asthma-like symptoms may continue for months or even years after exposure to the materialceases. This may be due to a non-allergenic condition known as reactive airwaysdysfunction syndrome (RADS) which can occur following exposure to high levels of highlyirritating compound. Key criteria for the diagnosis of RADS include the absence ofpreceding respiratory disease, in a non-atopic individual, with abrupt onset ofpersistent asthma-like symptoms within minutes to hours of a documented exposure to theirritant. A reversible airflow pattern, on spirometry, with the presence of moderate tosevere bronchial hyperreactivity on methacholine challenge testing and the lack ofminimal lymphocytic inflammation, without eosinophilia, have also been included in thecriteria for diagnosis of RADS. RADS (or asthma) following an irritating inhalation is aninfrequent disorder with rates related to the concentration of and duration of exposureto the irritating substance. Industrial bronchitis, on the other hand, is a disorder thatoccurs as result of exposure due to high concentrations of irritating substance (oftenparticulate in nature) and is completely reversible after exposure ceases. The disorderis characterised by dyspnea, cough and mucus production. Allergic reactions involving the respiratory tract are usually due to interactionsbetween IgE antibodies and allergens and occur rapidly. Allergic potential of theallergen and period of exposure often determine the severity of symptoms. Some people maybe genetically more prone than others, and exposure to other irritants may aggravatesymptoms. Allergy causing activity is due to interactions with proteins. Attention should be paid to atopic diathesis, characterised by increased susceptibilityto nasal inflammation, asthma and eczema. Exogenous allergic alveolitis is induced essentially by allergen specific immune-complexes of the IgG type; cell-mediated reactions (T lymphocytes) may be involved. Suchallergy is of the delayed type with onset up to four hours following exposure. Isocyanate vapours are irritating to the airways and can cause their inflammation, withwheezing, gasping, severe distress, even loss of consciousness and fluid in the lungs. continued.

Hydrolysis would represents the primary fate mechanism for the majority of the commercialisocyanate monomers, but, is tempered somewhat by the lack of water solubility. In theabsence of hydrolysis, sorption to solids (e.g., sludge and sediments) will be theprimary mechanism of removal. Biodegradation is minimal for most compounds andvolatilisation is negligible. Atmospheric degradation is not expected with removal fromair occurring by washout or dry deposition. Volatilisation from surface waters (e.g.,lakes and rivers) is expected to take years. In wastewater treatment this process is notexpected to be significant. Review of the estimated properties of the isocyanates suggest that sorption is theprimary removal mechanism in the ambient environment and in wastewater treatment in theabsence of significanthydrolysis. Sorption to solids in wastewater treatment is considered strong to verystrong for mostcompounds. Sorption to sediments and soils in the ambient environment is very strong inmost instances. Migration to groundwater and surface waters is not expected due tosorption or hydrolysis. Hydrolysis of the N=C=O will occur in less than hours in most instances and withinminutes for more than 90% of the commercial isocyanates. However, the low to very lowsolubility of these substances will generally lessen the effectiveness of hydrolysis as afate pathway. But hydrolysis should be considered one of the two major fate processes forthe isocyanates. Aerobic and/or anaerobic biodegradation of the isocyanates is not expected to occur atsignificant levels. Most of the substances take several months to degrade. Degradation of the hydrolysis products will occur at varying rates depending on themoiety formed. DO NOT discharge into sewer or waterways.
