A questionnaire survey was conducted among medical students on their awareness of laboratory safety knowledge during epidemic prevention of COVID19.The results show that students who have had the experience of laboratory practice had higher scores on the knowledge of COVID19 epidemic prevention, firefighting, laboratory operation and storage of dangerous chemicals (P values were all less than 0.05).The comparison of the correct rate of each subject showed that the students who had the experience of laboratory practice was better at knowledge of firefighting,laboratory operation and storage of dangerous chemicals.Conclusion was made that medical students had a better knowledge of epidemic prevention and firefighting,however the knowledge of laboratory operation and storage of dangerous chemicals needs to be improved.
