(1) Heat transfer oil boiler has the characteristics of low pressure and high temperature, which is widely used in textile printing and dyeing, wood processing, petrochemical, food and other industries. However, the low pressure of working characteristics does not mean that the safety of the heat transfer oil boiler is better than that of the steam boiler with high working pressure. The heat transfer oil boiler and heat equipment are a whole, which requires continuous and closed operation. The failure of any part of heat transfer oil boiler, pipeline, flange, valve and thermal equipment can cause accidents. The accident rate of the boiler is higher than that of the boiler oil. In 1986-1990, there were 15 accidents of heat-conducting oil boilers in Shaoxing City, Zhejiang Province alone, including one explosion accident, with an average annual accident rate of 2%, while the average annual accident rate of steam boilers in the same period was 0.3% (above major accidents); from 1993 to 1995, there were 47 accidents of heat-transfer oil boilers in Shaoxing County, with an average annual accident rate of 7.7%, while there were only 11 major accidents of steam boilers in this county during the same period
The average accident rate was 0.5%. It can be seen that the safety management and accident prevention of heat transfer oil boiler should be more urgent and important
 
(2) Most of the heat transfer oil boilers are flammable and explosive media with strong permeability. Therefore, once the leakage occurs, it is easy to cause fire and even secondary explosion. According to the statistics of fire accidents in Shaoxing County, fire accidents caused by fire accounted for 37.31% of the total in 1993
 
(3) Heat transfer oil boiler also belongs to toxic medium. In case of accident leakage, personal protection should be taken to prevent poisoning
