In order to ensure the health and safety of passengers and employees, the subway company should formulate relevant rules and regulations, make it clear that employees are not allowed to go to work with illness, and should require employees to have their body temperature tested every day to ensure their health. If employees have symptoms or abnormal body temperature, they should ask for leave immediately and undergo physical examination to ensure the health and safety of themselves and others. At the same time, the subway company should also strengthen the training of employees' health and safety knowledge, and improve employees' health awareness and protection awareness.
