Before inspecting the industrial processes within an occupancy, a company officer must thoroughly:

Researching the applicable occupancy code requirements is critical before inspecting industrial processes within an occupancy. This preparation ensures that the officer is knowledgeable about the specific regulations and standards that govern the occupancy's operations, which can include safety protocols, fire prevention measures, and legal compliance. By understanding the relevant codes, the officer can effectively assess whether the facility is adhering to safety standards that safeguard both workers and emergency responders.

Having this foundational knowledge allows the officer to conduct a more focused and organized inspection. It helps identify potential hazards specific to the type of occupancy in question and to evaluate processes that may pose fire risks. Being informed about occupancy codes also aids in recognizing areas for improvement and ensuring that any necessary corrective actions are taken to enhance safety and compliance.

The other options, while important in their own contexts, do not directly contribute to the preparatory phase necessary for a thorough inspection of industrial processes. For instance, checking the fire department connection or documenting housekeeping procedures might be relevant during the inspection process itself, but they are not foundational actions to take prior to beginning an inspection. Decontaminating personal protective equipment is also significant but is a procedural step rather than preparatory research.
