According to BPI standards, what is the first action to take before entering a building?

The recommended first action before entering a building, in accordance with BPI standards, is to put on the CO (carbon monoxide) alarm. This step is crucial for ensuring the safety of anyone entering the space, as carbon monoxide is a colorless, odorless gas that can lead to serious health risks. By activating the CO alarm, the technician can detect any hazardous levels of carbon monoxide before entering the area.

Safety protocols prioritize the health and well-being of the technician by ensuring that harmful conditions are monitored before any assessment or work begins. This practice is essential not only for compliance with safety standards but also to establish a secured working environment. Other actions, such as checking fuel levels, turning off appliances, or notifying the building owner, are important but should occur after confirming that it is safe to enter the building.
