What is the maximum time allowed for handcranking during a power failure?

In the context of dialysis and water treatment, the maximum time allowed for handcranking during a power failure is specified because it ensures that the equipment continues to operate effectively while minimizing the risk of complications. The time frame of 10-15 minutes is chosen to allow sufficient time for emergency procedures without overexerting personnel or causing potential damage to the equipment.

Hand cranking typically refers to the manual operation of devices that otherwise rely on electrical power. Limiting this operation to a maximum of 10-15 minutes helps maintain the integrity of the system and ensures that essential processes, such as water treatment and blood purification in dialysis, can continue safely. Operating beyond this specified time could lead to less efficient water circulation, potential contamination, or inadequate treatment, putting patients at risk.

This timeframe balances the need for immediate response in emergency situations while also providing a clear guideline for healthcare professionals on the safe limits of manual operation in the event of power outages.
