Dichloromethane 75-09-2 99.9

See Section 8 for information on permissible exposure limits and threshold limit values

Section 3. Hazards Identification

Physical State and Appearance Colourless, liquid with irritating odour

Hazard Summary Toxic, irritant

Routes of Exposure Skin and eye contact, inhalation and ingestion

Potential Acute Health Effects Skin: Irritant.Prolonged and repeated contact will cause

irritation and potentially burns. Contact leaves burning and thencold sensation. Should not be absorbed through the skin.

Eyes: Irritant. Irritation may be slow to heal. Vapour may cause

eye irritation, discomfort and redness. Can cause corneal injury.

Inhalation: Toxic, irritant. May cause irritation to the upper

respiratory tract. Excessive exposure may cause unconsciousnessand death. May cause carboxyhemoglobinemia impairment of

the bloods ability to transport oxygen. Anesthetic effects can be

observed at levels in the range of 500 1000 ppm. Progressively

higher levels (over 1000 ppm) can cause dizziness, drunkenness,and as low as 10,000 ppm, unconsciousness and death. These

high levels may also cause cardiac arrhythmias (irregular heart

beat).Ingestion: Oral toxicity is low. Small amounts ingested

incidentally during handling are not considered likely to cause

injury. Larger amounts are considered harmful. Aspiration intothe lungs may occur during ingestion or vomiting, resulting in

lung injury.

Medical Conditions

Aggravated by Exposure

Crboxyhemoglobinemia may aggravate any pre-existing

condition sensitive to a decrease in available oxygen, such as

chronic ling disease, coronary artery disease or anemias

See Toxicological Information Section 11

Additional Hazard None

Identification Remarks

Section 4. First Aid Measures

Eye Contact Flush eyes with water for 15 minutes. Remove contact lenses. Seek

medical attention.

Skin Contact Flush area with water. If irritation persists seek medical attention.

Launder clothing before reuse.

Inhalation Remove victim to fresh air. If there is difficulty breathing, seekimmediate medical attention, give artificial respiration.

Ingestion Give two glasses of water. Do not induce vomiting. Lay victim on leftside to prevent aspiration of any vomit. Seek immediate medical

attention.

Notes to Physician Rapid absorption through the 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, suggest endotrachealand/or esophageal control. Danger from lung aspiration must be

weighed against toxicity when considering emptying the stomach. No

specific antidote. Supportive care. Treatment should be based on thejudgment of the physician in response to the reactions of the patient. If

burn is present, treat as any thermal burn after decontamination.

Additional First AidRemarks

None
