If products are mixed, additional toxic chemicals may be released into the air through chemical reaction. A common example is ammonia and chlorine bleach, which are found in many household cleaners. When mixed, they react to form a toxic gas. VOCs are organic solvents that easily evaporate into the air. VOCs can be toxic and harmful to the environment.
Many products containing VOCs can be dangerous or flammable, especially if used improperly.
Water-based products tend to be less hazardous to indoor air than products that are based on organic solvents. When possible, use VOC products outdoors where compounds are more widely dispersed. Provide plenty of ventilation and fresh air if VOC products must be used indoors. If indoor use of VOC products is required, schedule activities for a time when the weather is mild so doors and windows can be opened for ventilation. When using VOC products, take regular breaks for fresh air and be alert for possible reactions to the chemicals.
