Final answer:
The process called 'Defusing' takes place shortly after a critical incident, providing emergency service workers a platform to discuss the incident and begin coping with the stress.
Step-by-step explanation:
The event that takes place within 1 to 4 hours after a critical incident and is designed to start the process of helping emergency providers work through a stressful situation is known as Defusing. This process is an early intervention and is part of critical incident stress management which aims to reduce the immediate stress and allow emergency service workers to quickly return to normal duties. Defusing is a confidential, voluntary, and non-evaluative meeting led by trained individuals, providing a safe space to discuss the incident, normalize stress reactions, and inform on possible coping strategies. This is distinctly different from a debate or a hearing, and should not be confused with the likes of performance reviews, self-medicating, or reprimands.
