Final answer:
A pre-hot work check is conducted by a competent individual, such as a fire watch or safety officer, who confirms safety measures are in place before hot work starts.
Step-by-step explanation:
The pre-hot work check must be conducted by a competent and authorized individual, typically someone who is knowledgeable about the hazards associated with hot work and who has the authority to approve the commencement of hot work. This person is often referred to as a fire watch or safety officer, and is responsible for ensuring that all necessary safety measures are in place before any hot work (such as welding, cutting, or grinding) begins. This may include checking for flammable materials, ensuring proper ventilation, and having firefighting equipment ready.
