We use several different anti-microbials or biocides during every water damage mitigation job. These prevent mold, mildew, and bacterial growth. And most of them are rated safe for children and pets. But, if you have concerns about toxicity or chemical exposure, ask the technician on call which anti-microbial solution he will be using. You can also ask him to provide you with the Material Safety Data Sheets (MSDS sheets) for that product. But to be safe, it’s wise to keep yourself, children, and pets away during the drying process.
