Are Pressure canners dangerous?
Beside this, are Pressure canners safe?
"Pressure canning is the only safe method for home canning vegetables. Clostridium botulinum is the bacterium that causes botulism food poisoning in low-acid foods, such as vegetables. Only subjecting it to the higher temperatures (240 F) of a pressure canner can the spores be killed.
Similarly, it is asked, how dangerous are pressure cookers?
Pressure cookers are dangerous. They can explode, in a sense, but not as violently as you might fear (or hope). The pressure inside a consumer cooker doesn't go above about two atmospheres—about the pressure inside a can of soda.
When a liquid under pressure is suddenly depressurized, the gases it contains, including steam, rapidly expand. They can 'explode' out of the pot with catastrophic results for those nearby. This is not an actual explosion that results from combustion, but the rapid, almost instantaneous expansion of gases.
