or its combustion products. Self contained breathing apparatus with a full facepiece operated in a pressure demand or otherpositive pressure mode. Disperse vapors with water spray if they have not ignited. Cool containing vessels with floodingquantities of water until well after fire is out.
Fire and Explosion
Dichloromethane vapors concentrated in a poorly ventilated area can be ignited upon contact with a high intensity source
of heat. Vapor forms explosive mixture with air. The sensitivity to static discharge is not available. The sensitivity toimpact is not available. Emits toxic fumes under fire conditions.
Section V. Toxicological Properties
Routes of entry
Inhalation and ingestion. Eye contact. Skin contact. Skin absorption.
Harmful by ingestion, inhalation or skin absorption. Irritant. Dichloromethane is metabolized to carbon monoxide which reduces the blood's
Effects of Acute
ability to carry oxygen (carboxyhemoglobinemia). May be fatal. Target organs: skin, cardiovascular system, eyes, central nervous system, (in
animals: lung, liver, salivary gland and mammary gland tumors). 2300 ppm (DICHLOROMETHANE) is immediately dangerous to life or health.
Irritation, corneal burns, conjunctivitis and possible corneal damage.
Causes irritation, defatting, drying, and craking of the skin. Possibility of skin burns if not removed rapidly. May causedermatitis. May be absorbed through the skin.
Vapors are irritating to the nose, throat and respiratory tract. In confined or poorly ventilated areas, vapors can readilyaccumulate and can cause unconsciousness and death. Minimal anaesthetic or narcotic effects may be seen in therange of 500-1000 ppm dichloromethane. May cause cyanosis, central nervous system depression, cardiac arrythmia,systemic poisoning, and asphyxiation. Excessive exposure may cause carboxyhemoglobinemie, thereby impairing theblood's ability to transport oxygen. See ingestion.
May cause irritation and burning of the mouth, throat and respiratory tract. May cause cyanosis, abdominal pain, centralnervous system depression (headache, nausea, vomiting, drowsiness, weakness, dyspnea, incoordination, etc.), cardiacarrythmia, liver and kidney damage, and systemic poisoning and death possible. Guard against aspiration into lungs (maycause chemical pneumonitis which can be fatal).
Section V. Toxicological Properties
Effects of Chronic
May cause carboxyhemoglobinemia, encephalopathy, central nervous system depression, liver, kidney, lung, blood, skin, eye
and pancreas damage. Animal: causes cancer of the lungs, liver, salivary and mammary glands. Potential carcinogen.
IARC: 2B Possibly carcinogenic to humans. ACGIH: A3 Confirmed animal carcinogen with unknown relevance to humans.
Possible mutagen. Human: passes through the placenta, excreted in maternal milk. In vitro studies in mammal cells haveshown mutagenic action. Dichloromethane can cause adverse effects on the blood. These effects include blood in the urine,anemia, and carboxyhemoglobinemia caused by metabolism of dichloromethane to carbon dioxide in the blood. Initialmanifestation of carboxyhemoglobinemia is cyanosis, characterized by cherry-red lips, tongue and mucous membranes andjaundice. Teratogenic effects: Not available. Toxicity of the product to the reproductive system: Not available. To the best ofour knowledge the chronic toxicity of this substance has not been fully investigated.
Section VI. First Aid Measures
Immediately flush eyes with large amounts of water for at least 20 minutes holding lids apart to ensure flushing of theentire surface. Obtain immediate medical attention.
Immediately flush skin with plenty of water and soap for at least 20 minutes while removing contaminated clothing andshoes. Call a physician. Wash contaminated clothing before reusing.
Remove patient to fresh air. Administer approved oxygen supply if breathing is difficult. Administer artificial respiration orCPR if breathing has ceased. Seek immediate medical attention. Do not give vasopressor drugs (epinephrine, adrenaline,ephedrine, etc.) as there may be damger of cardiac arrythmia.
DO NOT induce vomiting. If conscious, wash out mouth with water. Immediately transport victime to an emergencyfacility. If spontaneous vomiting occurs, have victim lean forward with head down to avoid breathing in of vomitus.
Emergency Medical Care: Because rapid absorption may occur through lungs if aspirated and cause systemic effects,the decision of whether to induce vomiting or not should be made by a physician. If lavage is performed, suggestendotracheal and/or esophageal control. Danger from lung aspiration must be weighed against toxicity when consideringemptying the stomach. Exposure may increase "myocardial irritability". Do not administer sympathomimetic drugs unlessabsolutely necessary. If burn is present, treat as any thermal burn, after decontamination. There is no specific antidote.
Supportive care. Treatment based on judgement of the physician in response to reactions of the patient.
Carboxyhemoglobinemia may aggravate any preexisting condition sensitive to a decrease in available oxygen, such aschronic lung disease, coronary artery disease or anemias.
Section VII. Reactivity Data
Stable. Conditions to avoid: High temperatures, sparks, open flames and all other sources of ignition, contamination.
Hydrogen chloride, chlorine, phosgene.
Oxidizing agents, bases, alkali metals such as potassium and sodium, metals such as zinc, aluminum, and magnesium,powdered metals, reducing agents, nitric acid, amines, aluminum trichloride, nitrogen trioxide, ethylene, acids may causefires and explosions. May attack some forms of plastics, rubbers and coatings.
May react violently with metals such as sodium, potassium and barium, particularly if they are finely divided. Hydrolysisproducing small amounts of hydrochloric acid is possible with gross water contamination. Hazardous polymerization willnot occur.
Section VIII. Preventive Measures
Protective Clothing in
Wear self-contained breathing apparatus, rubber boots and heavy rubber gloves. Full suit.
case of spill and leak
Spill and leak
Evacuate the area. Eliminate all sources of ignition. Absorb on sand or vermiculite and place in a closed container fordisposal. Ventilate area and wash spill site after material pick up is complete. DO NOT empty into drains. DO NOT touchdamaged container or spilled material. Stay upwind: Keep out of low areas. Prevent entry into sewers, basements orconfined areas; dike if needed.
Dispose of waste material at an approved (hazardous) waste treatment/ disposal facility in accordance with applicablelocal, provincial and federal regulations. This material and its container must be disposed of in a safe way. Harmful toaquatic life at low concentrations. Can be dangerous if allowed to enter drinking water intakes. Do not contaminatedomestic or irrigation water supplies, lakes, streams, ponds, or rivers.
Storage and Handling
Keep at temperature not exceeding 25°C. Store in a cool place away from heated areas, sparks, and flame. Store in a well ventilated area.
Store away from incompatible materials. Do not add any other material to the container. Do not wash down the drain. Do not breathegas/fumes/vapor/spray. In case of insufficient ventilation, wear suitable respiratory equipment. Keep away from direct sunlight or strongincandescent light. Keep container tightly closed and dry. Manipulate under an adequate fume hood. Empty containers may contain ahazardous residue. Handle and open container with care. Take off immediately all contaminated clothing. This product must be manipulatedby qualified personnel. Do not get in eyes, on skin, or on clothing. Wash well after use. In accordance with good storage and handlingpractices. Do not allow smoking and food consumption while handling. Never use welding or cutting torch on or near drum (even empty)because product (even just residue) can ignite explosively. Wear suitable protective clothing. Do not use pressure to dispense. Do not usehandling equipment or containers composed of magnesium, aluminum or their alloys. Protect from moisture. Watch for accumulation in lowconfined areas. In case of accident or if you feel unwell, seek medical advice immediately (show the label when possible.).
Section IX. Protective Measures
Splash goggles. Impervious vitron gloves, apron, coveralls, and/or other resistant protective clothing. Sufficient to protect skin. Prior to use, user should confirm
impermeability. A NIOSH/MSHA-approved air-purifying respirator equipped with organic vapor cartridges for concentrations up to 50 ppm. An air-suppliedrespirator if concentrations are higher or unkown. Have available and use as appropriate: face shields, rubber suits, aprons, and boots. Do not wear contactlenses. Make eye bath and emergency shower available. Ensure that eyewash station and safety shower is proximal to the work-station location.
Use only in a chemical fume hood to keep airborne levels below recommended exposure limits. Use explosion-proofventilation equipment. Do not use in unventilated spaces. Vapors are heavier than air and may travel along the ground orpool in low areas. Because vapor is heavy, ventilation must be provided at floor level as well as at higher levels.
