Final answer:
When splashed with cryogenic liquids like LOX or LIN, the proper treatment is to immediately remove any contaminated clothing and gently rinse the affected area with lukewarm water, not hot, and seek medical attention.
Step-by-step explanation:
The proper treatment for someone who has been splashed with cryogenic liquids, such as liquid oxygen (LOX) or liquid nitrogen (LIN), is to remove contaminated clothing and seek immediate medical attention. Cryogenic burns must be handled with caution to avoid further tissue damage. Contrary to common first-aid procedures that often involve the use of warm water or heat to treat burns, such methods are not appropriate for cryogenic burns due to the extreme cold involved.
As a first aid measure, victims should also gently rinse the affected area with lukewarm water if it is available and safe to do so, never hot water, as it might cause additional thermal shock to the tissues already damaged by extreme cold. It's important to not rub the affected area as rubbing can cause further injury. Covering with a blanket is not recommended as it will not address the injury and may retain the cryogenic liquid on the skin, whereas applying direct heat can cause further damage through rapid rewarming.
Always follow safety protocols when working with cryogenic liquids and ensure that proper protective clothing, such as face protection, insulated gloves, and aprons, is worn at all times. If an accidental splash occurs, it's critical to act quickly and efficiently to minimize injury.
