Emergency treatment of Hexamethyldisiloxane :

1. Emergency treatment for leakage
①Quickly evacuate the personnel in the leaking contaminated area to the safe area, and isolate them, strictly restricting access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive-pressure breathing apparatus and fire protection clothing. Cut off the source of leakage as much as possible to prevent entering restricted spaces such as sewers and drying ditches.
②Small leakage: Absorb with sandy vermiculite or other non-combustible materials. Or incinerate on the spot if safety is guaranteed.
③Large leakage: Construct dikes or dig pits for containment. Cover with foam to reduce vapor hazards. Use an explosion-proof pump to transfer to a tank truck or a special collector, recycle or transport to a waste disposal site for disposal.

2. Protective measures
①Respiratory system protection: When the concentration in the air exceeds the standard, a self-priming filter gas mask (half mask) should be worn. When emergency rescue or evacuation, it is recommended to wear self-contained breathing apparatus.
②Eye protection: Wear chemical safety goggles.
③Physical protection: wear anti-poison infiltration overalls.
④ Hand protection: wear rubber gloves.
⑤Others: Smoking is strictly prohibited at the workplace. After work, take a shower and change clothes. Pay attention to personal hygiene.

3. First aid measures
①Skin contact: Take off the contaminated clothing, and wash the skin thoroughly with soapy water and clean water.
②Eyes contact: Lift eyelids and rinse with flowing water or normal saline. Seek medical attention.
③Inhalation: Quickly leave the scene to a place with fresh air. Keep the airway open. If breathing is difficult, give oxygen. If not breathing, give artificial respiration immediately. Seek medical attention.
④Ingestion: Drink enough warm water and induce vomiting. Seek medical attention.
