Abstract: According to the characteristics of the transportation technology of the side tank, the height of the metal dome-type tank varies with the amount of oil coming from the tank during its operation, so the space of oil and gas changes accordingly. Especially when storing high hydrogen sulfide crude oil, the existence of such explosive mixture of toxic gases will inevitably bring serious risks to the safe operation of the tanks. Therefore, prevention, isolation, control, fighting and other means from such aspects as technology, risk control, management and so on shall be adopted to prevent and reduce fire hazards, reduce the volatilization of toxic and harmful gases so as to protect personal and property safety. The author puts forward the preventive measures from the existing mode of operation and management.

Key words: dome-type tank, crude oil with high hydrogen sulfide content, preventive measures
