What is indicated by a scale of 1-4 in hazard identification?

The scale of 1-4 in hazard identification typically represents increasing levels of risk or deadliness associated with specific hazards. When using such a scale, a score of 1 may signify a low hazard and a score of 4 indicates a much higher and potentially catastrophic hazard. This numerical categorization allows emergency responders and planners to assess the potential severity of various scenarios quickly and to prioritize their responses and resources accordingly.

In this context, recognizing the increasing deadliness on a 1-4 scale allows teams to focus on the most severe risks first. Codes like this are essential for effective risk management and for making informed decisions regarding preparedness and response, as they provide a clear and systematic way to evaluate potential dangers.
