Final answer:
Frostbite can happen as quickly as frostnip in situations like exposure to temperatures below -30 degrees Celsius, inadequate hand and foot protection, or contact with cold compressed gas.
Step-by-step explanation:
Frostbite is a condition in which skin and other tissues freeze due to exposure to severe cold temperatures. It typically develops more gradually than frostnip, which is a milder form of cold injury. However, there are scenarios where frostbite can occur as rapidly as frostnip. For instance, when the temperature falls below -30 degrees Celsius, the extreme cold can lead to quick frostbite, especially on exposed skin or if proper protection is not worn. Another scenario is when a worker has inadequate hand and foot protection, leaving these parts vulnerable to rapid freezing. Similarly, exposure to cold compressed gas can cause rapid frostbite due to the extremely low temperatures of the gas.
