To prevent any risks of exposure, use protective PPE such as impermeable gloves, chemical-resistant clothing, and a face shield while applying the biocide. In addition, keep the public away from the treated area. After the biocide has been applied, rinse all application equipment with fresh water. Do not allow the rinse water to flow into surface drains or flowerbeds.
