1. Alcohol should not be used for large-scale spraying and disinfection of environmental surfaces. For example, corridors, conference rooms and offices are not allowed to be disinfected with alcohol spray.

2. It is not recommended to spray alcohol on clothes for disinfection. It may burn in case of open fire or static electricity.

3. When using alcohol, it is necessary to ensure ventilation and stay away from high-temperature items, and never touch open flames. Such as cooking, talking on the phone, smoking, using electric mosquito swatter, etc. It can't be done immediately after spraying high-concentration alcohol, and a fire may occur if the alcohol concentration in the air exceeds 3%.

4. Before using alcohol, clean up the surrounding flammable and combustible substances, and do not spray them directly in the air. To disinfect the surfaces of electrical appliances and cookers, turn off the power supply and fire source first, and then wipe them after the electrical appliances and cookers are cooled, so as to avoid the explosion caused by alcohol volatilization.

5. Store alcohol carefully, away from fire sources, and keep it out of reach of children.
