Final answer:
The amount of equipment needed is not a consideration for an EMT in establishing the size of the danger zone.
Step-by-step explanation:
In establishing the size of the danger zone, an EMT should consider various factors to ensure the safety of themselves and others. However, the amount of equipment needed is not one of those considerations. The EMT should take into account the presence of hazardous materials, as these may pose a risk to health, the wind direction, as it can affect the spread of hazardous substances, and whether there is a fire present, as it can escalate the danger level.
