Precautions and Emergency Procedures for Hexamethyl Disiloxane

　　Health hazards
　　Inhalation, ingestion, or skin absorption can be harmful to the body. It is irritating to the skin. Its vapor or mist irritates the eyes, mucous membranes, and upper respiratory tract.
　　Emergency Response
　　Leak Emergency Response
　　Immediately evacuate personnel from the leak-contaminated area to a safe zone and isolate the area, strictly controlling access. Eliminate any ignition sources. Emergency responders are advised to wear self-contained positive-pressure respirators and fire-resistant protective suits. If possible, stop the leak at its source to prevent it from entering confined spaces such as sewers or drainage ditches. For small spills, absorb the material using non-combustible materials like sand, vermiculite, or other suitable absorbents—and if safe to do so, burn it on-site. In cases of large-scale leaks, create containment barriers or dig pits to collect the spillage. Apply foam to suppress vapor emissions and minimize the risk of vapor-related hazards. Use explosion-proof pumps to transfer the substance into tank trucks or dedicated collection containers for recovery or disposal at an appropriate waste treatment facility.
　　Protective measures
　　Respiratory Protection: When airborne concentrations exceed safe levels, a self-priming filter-type respirator (half mask) should be worn. In emergency rescue or evacuation situations, it is recommended to use a self-contained breathing apparatus.
　　Eye protection: Wear chemical safety goggles.
　　Personal protective equipment: Wear a chemical-resistant, anti-penetration work suit.
　　Hand protection: Wear rubber gloves.
　　Others: Smoking is strictly prohibited at the workplace. After finishing work, please shower and change clothes. Remember to maintain personal hygiene. [1]
　　First aid measures
　　Skin contact: Remove contaminated clothing and thoroughly rinse the skin with soap and water.
　　Eye contact: Lift the eyelid and rinse with running water or saline solution. Seek medical attention.
　　Inhalation: Quickly remove the person to a place with fresh air. Keep airways clear. If breathing is difficult, administer oxygen. If breathing stops, immediately perform artificial respiration and seek medical attention.
　　Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.
　　Fire suppression methods
　　Cool the container with water spray, and if possible, move the container away from the fire area to an open space. Extinguishing agents: carbon dioxide, dry powder, or sand/earth. Never use water or foam to extinguish the fire.
　　Security Terminology
　　S16: Keep away from sources of ignition. Avoid contact with fire.
　　Risk terminology
　　R11: Highly flammable. Highly flammable.
　　Important Notes
　　1. During storage, do not expose to open flames; ensure proper ventilation and keep the area dry, protected from direct sunlight. Storage temperature should be maintained between -50°C and 45°C.
　　2. During transportation, avoid collisions, protect from rain and sunlight, and handle storage and transport according to hazardous material regulations.
