Some of the most common injuries that befall janitorial workers are a result of chemical contact with skin, eyes or mouth, or the inhalation of fumes. A system that requires employees to mix chemical concentrates with water to produce diluted cleaning chemicals is likely to contribute to a number of these injuries.

Dilution control systems virtually eliminate human contact with chemical concentrates, which are being mixed with water prior to being dispensed. If a worker or building occupant comes into contact with the diluted mixture, they are much less likely to be injured. However, to minimize contact with diluted chemical mixtures, protective gloves, goggles and clothing are recommended, and MSDS sheets should always be carefully read. Also, all employees should be properly trained on how to use a dilution control system and to read all labels prior to using a chemical.
