Steam escapes from a pressure cooker when the pressure inside becomes greater that the weights used on the safety valve in the lid. Excessive escaping steam signals it is time to turn down the gas or electricity slightly. (Otherwise, the pressure cooker would eventually explode if the safety valve was not there to relieve the steam pressure!)

A safety device commonly built into a fold-down lid cooker is a pressure release valve. This valve helps regulate the internal pressure within the cooker to prevent it from exceeding safe levels, reducing the risk of explosion or other safety hazards. It is a crucial component in ensuring the safe operation of pressure cookers and similar devices.

The main danger in using a modern pressure cooker is being burned by steam.Modern pressure cookers have been re-engineered to eliminate the kitchen explosions of the past. They now have a number of safety features built in that prevent and release over pressure. But by the very nature of how a pressure cooker works there is still a slight chance of a steam burn occuring. Read the instruction manual and follow it and you shouldn't have any problems.
No, it is not safe to place dry ice in a pressure cooker because the rapid sublimation of dry ice into gas could cause a dangerous pressure buildup, resulting in potential explosion or injury. It is important to always follow safety guidelines and use dry ice in appropriate containers or environments.
When the safety valve melts, the pressure inside the pot will increase rapidly until it reaches the system's maximum pressure. This can vary depending on the type of pressure cooker, but it is typically around 15 psi (pounds per square inch) for most stovetop pressure cookers.

As the pressure increased, eventually the container would burst. Before such a dangerous pressure is reached, a safety valve would open and automatically release the pressure, preventing the container from bursting. An example is the safety valve fitted to the lid of a domestic pressure cooker used in the kitchen. When the safety valve opened, steam would be released and warn the cook to turn heat on the kitchen stove down to a safer level.
