1. Alcohol should not be used for spraying in large area to sterilize  environmental surfaces. Stairs, conference rooms, offices, etc. cannot be  disinfected with alcohol spray. 2. It is not recommended to use alcohol spray to  disinfect clothes. If there are flames or static electricity, fire may occur. 3.  Alcohol should be stored carefully and kept away from sources of ignition or  place where children can easily reach. 4. When using alcohol for disinfection,  it is necessary to maintain ventilation and keep away from high-temperature  objects or open flames. After spraying alcohol in high concentration, the  following actions should not be performed, such as cooking, making phone calls,  smoking, using an electric mosquito slap, etc. 5. Before using alcohol, the  surrounding flammable materials should be cleared. Do not spray alcohol directly  in the air. When disinfecting the surface of the electric appliance or stove, it  is necessary to turn off the power or the fire source. In order to avoid  deflagration of the volatilizing alcohol, after the appliance and the stove are  cooled, you can wipe them with alcohol. 6. Smoking is strictly prohibited when  using alcohol.

　　Fires can be ignited when the concentration of ethanol in the air exceeds  3%. When a large amount of alcohol is used, the volatilization of alcohol  increases the concentration of ethanol in the indoor air, which is more  dangerous than directly igniting the alcohol. Therefore, it is necessary to  ventilate the room in time.
