HARMFUL - May cause lung damage if swallowed. Highly flammable. Vapors may cause dizziness or suffocation. Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. POTENTIAL HEALTH EFFECTS ACUTE HEALTH EFFECTS SWALLOWED ! Swallowing of the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis; serious consequences may result. (ICSC13733). ! Accidental ingestion of the material may be damaging to the health of the individual. ! Ingestion of methylcyclohexane may be harmful. Death may occur as a result of central nervous system depression and possible circulatory collapse. ! Considered an unlikely route of entry in commercial/industrial environments. The liquid may produce gastrointestinal discomfort and may be harmful if swallowed. Ingestion may result in nausea, pain and vomiting. Vomit entering the lungs by aspiration may cause potentially lethal chemical pneumonitis. EYE ! Although the liquid is not thought to be an irritant, direct contact with the eye may produce transient discomfort characterized by tearing or conjunctival redness (as with windburn). SKIN ! This material can cause inflammation of the skin oncontact in some persons. ! The material may accentuate any pre-existing dermatitis condition. ! Skin contact is not thought to have harmful health effects, however the material may still produce health damage following entry through wounds, lesions or abrasions. ! Repeated or prolonged contact with methylcyclohexane may result in itching, burning, redness, slight hypothermia, thickening and possible ulceration. ! Open cuts, abraded or irritated skin should not be exposed to this material. ! 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 ! Inhalation of vapours may cause drowsiness and dizziness. This may be accompanied by narcosis, reduced alertness, loss of reflexes, lack of coordination and vertigo. ! Inhalation of vapors or aerosols (mists, fumes), generated by the material during the course of normal handling, may be damaging to the health of the individual. ! There is some evidence to suggest that the material can cause respiratory irritation in some persons. The body's response to such irritation can cause further lung damage. ! In rabbits lethal doses of methylcyclohexane, produced conjunctival congestion, dyspnea, rapid narcosis and convulsions preceding death. Histologic changes in animals exposed to methylcyclohexane resemble those induced by cyclohexane. ! Inhalation of high concentrations of gas/vapor causes lung irritation with coughing and nausea, central nervous depression with headache and dizziness, slowing of reflexes, fatigue and inco-ordination. ! Central nervous system (CNS) depression may include general discomfort, symptoms of giddiness, headache, dizziness, nausea, anaesthetic effects, slowed reaction time, slurred speech and may progress to unconsciousness. Serious poisonings may result in respiratory depression and may be fatal. ! Material is highly volatile and may quickly form a concentrated atmosphere in confined or unventilated areas. Vapor 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. ! In general, the alicyclic hydrocarbons produce less discomfort than thecorresponding aromatic compounds. CHRONIC HEALTH EFFECTS ! Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems. Due to almost complete elimination of methylcyclohexane from the body, the danger of chronic poisoning is relatively slight. Chronic solvent inhalation exposures may result in nervous system impairment and liver and blood changes. [PATTYS]. Section 3 - COMPOSITION / INFORMATION ON INGREDIENTS NAME CAS RN % methylcyclohexane 108-87-2 > 99 2 of 13 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. Avoid giving milk or oils. Avoid giving alcohol. If spontaneous vomiting appears imminent or occurs, hold patient's head down, lower than their hips to help avoid possible aspiration of vomitus. EYE ! 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. SKIN ! 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. INHALED ! 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 ! Any material aspirated during vomiting may produce lung injury. Therefore emesis should not be induced mechanically or pharmacologically. Mechanical means should be used if it is considered necessary to evacuate the stomach contents; these include gastric lavage after endotracheal intubation. If spontaneous vomiting has occurred after ingestion, the patient should be monitored for difficult breathing, as adverse effects of aspiration into the lungs may be delayed up to 48 hours. For acute or short term repeated exposures to petroleum distillates or related hydrocarbons: Primary threat to life, from pure petroleum distillate ingestion and/or inhalation, is respiratory failure. Patients should be quickly evaluated for signs of respiratory distress (e.g. cyanosis, tachypnea, intercostal retraction, obtundation) and given oxygen. Patients with inadequate tidal volumes or poor arterial blood gases (pO2 50 mm Hg) should be intubated. 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 A chest x-ray should be taken immediately after stabilization of breathing and circulation to document aspiration and detect the presence of pneumothorax. Epinephrine (adrenalin) is not recommended for treatment of bronchospasm because of potential myocardial sensitization to catecholamines. Inhaled cardioselective bronchodilators (e.g. Alupent, Salbutamol) are the preferred agents, with aminophylline a second choice. Lavage is indicated in patients who require decontamination; ensure use of cuffed endotracheal tube in adult patients. [Ellenhorn and Barceloux: Medical Toxicology]. Section 5 - FIRE FIGHTING MEASURES Vapor Pressure (mmHg): 36.903 @ 20 C. Upper Explosive Limit (%): 6.7 Specific Gravity (water=1): 0.77 Lower Explosive Limit (%): 1.2 EXTINGUISHING MEDIA ! Foam. Dry chemical powder. 3 of 13 BCF (where regulations permit). Carbon dioxide. Water spray or fog - Large fires only. FIRE FIGHTING ! Alert Emergency Responders and tell them location and nature of hazard. May be violently or explosively reactive. Wear breathing apparatus plus protective gloves. Prevent, by any means available, spillage from entering drains or water course. Consider evacuation (or protect in place). Fight fire from a safe distance, with adequate cover. If safe, switch off electrical equipment until vapor fire hazard removed. Use water delivered as a fine spray to
