Composition/information on ingredientscarbon monoxide100630-08-0 Ingredient nameCAS number%There are no additional ingredients present which, within the current knowledge of the supplier and in the concentrations applicable, are classified as hazardous to health or the environment and hence require reporting in this name: carbon monoxideOther means of identification:Monoxide; Flue gas; carbon oxide; carbonic oxide; Monoxide of carbon ; carbon monooxideCAS number:630-08-0 Substance/mixtureCAS number/other identifiers:Occupational exposure limits, if available, are listed in Section concentration shown as a range is to protect confidentiality or is due to batch code:001014As this product is a gas, refer to the inhalation flush eyes with plenty of water, occasionally lifting the upper and lower eyelids.

5 Check for and remove any contact lenses. Continue to rinse for at least 10 minutes. Get medical contaminated skin with plenty of water. Remove contaminated clothing and shoes. To avoid the risk of static discharges and gas ignition, soak contaminated clothing thoroughly with water before removing it. Continue to rinse for at least 10 minutes. Get medical attention. Wash clothing before reuse. Clean shoes thoroughly before victim to fresh air and keep at rest in a position comfortable for breathing. If it is suspected that fumes are still present, the rescuer should wear an appropriate mask or self-contained breathing apparatus. If not breathing, if breathing is irregular or if respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel.

6 It may be dangerous to the person providing aid to give mouth-to-mouth medical attention. If necessary, call a poison center or physician. If unconscious,place in recovery position and get medical attention immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or 4.

7 First aid measuresProtection of first-aiders:No action shall be taken involving any personal risk or without suitable training. If it is suspected that fumes are still present, the rescuer should wear an appropriate mask or self-contained breathing apparatus. It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation. Wash contaminated clothing thoroughly with water before removing it, or wear to physician:Treat symptomatically. Contact poison treatment specialist immediately if large quantities have been ingested or treatments:No specific this product is a gas, refer to the inhalation section.:IngestionOver-exposure signs/symptomsSkin contactIngestionInhalationAdverse symptoms may include the following:, reduced fetal weight, increase in fetal deaths, skeletal malformationsAdverse symptoms may include the following:, reduced fetal weight, increase in fetal deaths, skeletal malformationsAdverse symptoms may include the following:, reduced fetal weight, increase in fetal deaths, skeletal malformations:::Eye contact:No specific toxicological information (Section 11)Indication of immediate medical attention and special treatment needed, if necessarySection 5.

8 fire -fighting measuresPromptly isolate the scene by removing all persons from the vicinity of the incident if there is a fire . No action shall be taken involving any personal risk or without suitable training. Contact supplier immediately for specialist advice. Move containers from fire area if this can be done without risk. Use water spray to keep fire -exposed containers cool. If involved in fire , shut off flow immediately if it can be done without risk. If this is impossible, withdraw from area and allow fire to burn. Fight fire from protected location or maximum possible distance. Eliminate all ignition sources if safe to do thermal decomposition productsSpecific hazards arising from the chemicalDecomposition products may include the following materials: carbon dioxidecarbon monoxideContains gas under pressure .

9 Extremely flammable gas. In a fire or if heated, a pressure increase will occur and the container may burst, with the risk of a subsequent should wear appropriate protective equipment and self-contained breathing apparatus (SCBA) with a full face-piece operated in positive pressure protective equipment for fire -fightersUse an extinguishing agent suitable for the surrounding media:::None extinguishing media:Unsuitable extinguishing media:Special protective actions for fire -fighters:Section 6. Accidental release measuresPersonal precautions, protective equipment and emergency procedures:Accidental releases pose a serious fire or explosion hazard. No action shall be taken involving any personal risk or without suitable training.

10 Evacuate surrounding unnecessary and unprotected personnel from entering. Shut off all ignition sources. No flares, smoking or flames in hazard area. Do not breathe gas. Provide adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Put on appropriate personal protective non-emergency personnelDate of issue/Date of revision:11/5/2020 Date of previous issue:7/29/2020 MonoxideSection 6. Accidental release measuresEnvironmental precautionsImmediately contact emergency personnel. Stop leak if without risk. Use spark-proof tools and explosion-proof equipment.
