Start with the actual condition

Use. Use a safe cooled location for heat-sensitive occupants.

Do. Do not repeatedly reset a tripping breaker or open refrigerant components.

Step-by-step decision process

1. Identify the scope. Identify immediate danger before touching equipment or entering the area.
2. Shut the scope. Shut down the relevant utility only when the control is accessible and you know what it serves.
3. Move the scope. Move people, pets, and valuables away from the affected area.
4. Photograph the scope. Photograph conditions from a safe position and record when the problem began.
