During an ice incident safety briefing, what should the ISO emphasize?

Emphasizing the unpredictability of ice during an ice incident safety briefing is crucial because it highlights the inherent dangers associated with ice conditions. Ice can appear solid and safe but may have hidden flaws such as cracks, thin spots, or varying thickness depending on temperature changes and water flow, making it treacherous. By understanding its unpredictability, individuals are more likely to adopt a cautious attitude and take preventive measures when near ice. This awareness is key to ensuring safety and preventing accidents.

While the other options may address important aspects of safety in icy conditions, they do not encapsulate the key message necessary for overall hazard recognition. For instance, while CPR training is vital for emergency response, it does not directly mitigate the risks posed by unstable ice. The GO rescue technique may be effective but focusing on it without first reinforcing the unpredictability of ice might lead to overconfidence. Maintaining a high center of gravity can be useful for balance, but again, this doesn't address the more fundamental issue of the unpredictable nature of ice itself. Understanding that ice can be unpredictable sets the stage for broader safety practices.
