Pasteurisation means hot water at 80 to 90 C and open steam. Autoclaves run at 15 to 22 pounds per square inch and are pressure vessels: trained operator, working gauge, never opened under pressure.
A sealed spawn run room holds 10,000 to 15,000 parts per million of carbon dioxide, so vent it before anyone walks in. An end of crop cook out at 70 C means the room is not a workplace at all until it cools.
