When should a rope rescuer prepare a RISC chart during a rescue operation?

Preparing a RISC chart before starting the rescue operation is essential because it allows rescuers to assess and document the Risks, Information, Safety, and Command structure effectively. This proactive step ensures that all team members are aware of the potential hazards, operational parameters, and strategies that will be in place during the rescue. Establishing this chart prior to engaging in the rescue not only enhances situational awareness but also facilitates better communication among rescue personnel, which is crucial for safe and effective operations in potentially hazardous environments. Integrating this process at the beginning optimizes preparedness and helps in setting a clear plan of action, thereby increasing the chances of a successful outcome.
