In all processes for steel degassing under vacuum gases and vapors are formed that might be dangerous. Essentially CO and H2 as well as the vapors of volatile metals are released from the steel surface. Explosion protection in vacuum plants especially those that generate a large quantity of CO by the use of oxygen for decarburization so far has been assured by overpressure flaps at the metallurgical reaction vessels, alarm devices for water leakage, sensors for pressure and temperature as well as emergency venting with nitrogen. With the introduction of mechanical vacuum pumps efficient installations for gas cooling and dust separation became necessary.
