Thai Expert Warns Plastic-Wrapping Cars During Floods Could Cause Mold, Floating Risks

Bangkok — A Thai biology lecturer has cautioned drivers against using giant plastic bags to protect their cars from floodwater, citing potential risks of mold growth and vehicles floating away. Assoc. Prof. Dr. Jessada Denduangboripant, a lecturer at Chulalongkorn University, raised the concern after seeing images of these large plastic covers shared on social media.

While acknowledging the covers could be an emergency option for those unable to move their vehicles, Jessada emphasized the importance of not keeping them on for extended periods. Prolonged moisture accumulation within the sealed vehicle can create an environment conducive to mold growth, potentially damaging seats, steering wheels, and other interior parts.

Additionally, the trapped air inside the cover could give the car enough buoyancy to float away, especially in strong currents. Jessada urged motorists with alternative options to prioritize moving their cars to higher ground instead of relying on the plastic covers. For those who must use the covers, he recommended securing or weighting them to prevent drifting and placing moisture-absorbing products inside to reduce humidity.
