She says propylene is a respiratory hazard that could cause eye and skin irritation. She says people with asthma and allergies should be extra cautious if they're in the area.

You should use a half respirator and protect your skin if you're taking medication that makes your skin sensitive, Dr. Khan-Mayberry said.

Also, those with chronic skin diseases like psoriasis are urged not to drive in the area.
