When entering cabins or outbuildings that have been closed for a while, what is recommended before cleaning?

• A. Put on gloves and protective clothing
• B. Open them up and air out before cleaning
• C. Spray disinfectant on surfaces
• D. Remove all debris without cleaning

Answer: (B)

Ventilation first is essential when entering enclosed spaces that have been shut for a long time. Opening doors and windows to air out the cabin or outbuilding before cleaning reduces the concentration of dust, mold spores, bat or rodent guano, and any lingering fumes from decomposing matter or pesticides. This lowers the risk of inhaling harmful aerosols and helps you assess hazards safely. After the space is aired, proceed with cleaning using appropriate PPE and containment. Merely wearing protective clothing, spraying disinfectants in a closed space, or removing debris without cleaning doesn’t address the immediate buildup of contaminants and can increase exposure or leave hazards behind.
