Prestige pressure cooker safety features

Prestige pressure cookers are well known for their safety features. As described in a previous post, any vessel that operates under pressure is subjected to heavy forces and the mechanical design needs to take into consideration all of the forces that act in order to be able to withstand them. Additionally, any pressure vessel including the Prestige pressure cooker needs to have built in features that will allow for the safety of the user even if the pressures exceed the designed values.

The reason that careful evaluation and consideration are performed of Prestige pressure cooker built-in safety features is because of one major condition under which these pressure cookers operate as opposed to other gadgets that operate under what are called closed loop feedback systems. In systems that operate under closed loop feedback, when a designed parameter such as pressure or temperature exceeds a critical point, the external stimulus such as power to the gadget can be cut off automatically through the control system. However, in the case of pressure cookers in general, since the gadget sits on a heating source such as a range or stove, that is not connected electrically or mechanically to the pressure cooker, in case of an abnormal condition, the pressure cooker controls cannot switch of the heat source.

Therefore, Prestige pressure cookers rely on built-in safety devices that are designed to relieve excess pressure even if the stove or the range is left on as critical point is exceeded. The main safety features of the Prestige pressure cooker starts with a heavy wall construction of the vessel. The material of construction is either aluminum, hard anodized aluminum or stainless steel. Additionally, a dead weight safety valve is provided. Further safety includes a gasket release system and gasket offset device. Some of the models also include a pressure indicator as well as a resettable safety device. These safety devices allow for the operation of Prestige pressure cookers in a safe manner under critical conditions.

However, as the user of a Prestige pressure cooker, it is highly recommended that the operator tries to keep an eye on safety himself or herself by not operating the device in any unsafe manner. The instructions that come with the vessel must be carefully studied especially with regards to safe operation. As common sense would dictate, never allow children nearby when operating any pressure vessel and do not use the cooker to perform any non-cooking functions.
