Which of the following personnel could be employed in addition to the Project Manager?

The inclusion of a Health and Safety Officer in addition to the Project Manager is vital in a commercial drying project due to the unique hazards and risks associated with water damage restoration. This role is specifically focused on ensuring compliance with health and safety regulations, conducting risk assessments, and implementing safety protocols to protect both the workers and the environment. Their expertise is particularly important in situations where there may be concerns about mold growth, structural integrity, or exposure to harmful materials.

In contrast, the other roles listed do not directly relate to the specific needs of a drying project. A Head Chef, for example, primarily focuses on food preparation and kitchen management, which is outside the scope of a Project Manager's responsibilities in a restoration context. An Accountant handles financial records and budgeting, which, while important for overall business operations, doesn't directly contribute to the on-site management of a restoration project. Lastly, a Marketing Specialist is concerned with promoting services and client acquisition, rather than the operational or safety aspects of drying and restoration work. Therefore, the Health and Safety Officer is the most relevant and beneficial additional personnel for ensuring the project's success and safety compliance.
