Final answer:
Restorers working with loose soot should use appropriate HEPA air scrubbers and wear personal protective equipment (PPE) to ensure air quality and protect health.
Step-by-step explanation:
When working in areas containing loose soot residue, it is highly recommended that restorers use appropriate HEPA air scrubbers and don personal protective equipment (PPE). The use of HEPA air scrubbers helps to filter and remove particulate matter from the air, ensuring that the air quality is maintained, which is critical for the health and safety of the workers. Additionally, wearing PPE, including respiratory protection, is necessary to prevent inhalation of any harmful particles. Combining the use of appropriate air purification and protective wear under manufacturers' guidance and in well-ventilated conditions can help mitigate health risks during restoration or cleaning processes.
