The invention provides a dangerous waste vehicle transfer safety device. The device comprises a ventilation circuit. The ventilation circuit is characterized in that: a first end of a resistor R2, a negative electrode of a diode D1 and a first end of an input loop of a normally open relay K1 are respectively connected with a +12V power supply, a second end of a resistor R2 is respectively connected with a power supply input end IN of a switch chip U2 and a power supply end VDD of the switch chip U2, the positive electrode of the diode D1 is connected with the signal output end OUT of the switch chip U2 and the second end of the input loop of the normally open relay K1, the adjusting end of an adjustable resistor RP1 is connected with a gating end ST of the switch chip U2, and the grounding end of the switch chip U2 is connected with a power ground; and a first end of an output loop of the normally open relay K1 is connected with a first end of the power supply of a ventilator motor M, a second end of the power supply of the ventilator motor M is connected with a +24V power supply, and a second end of the output loop of the normally open relay K1 is connected with a power ground. When a gas sensitive sensor detects waste gas, the ventilator motor rotates, gas exchange is achieved, and accidents are avoided.
