Which of the following is a method to reduce chemical hazards?

Using vented manicure tables is a method to reduce chemical hazards because these tables are specifically designed to improve air quality and minimize exposure to harmful fumes associated with the chemicals used in nail services. The vents typically draw in air from the surrounding area and filter out airborne vapors and particles, preventing the buildup of potentially harmful substances that could affect both clients and cosmetologists. This method prioritizes safety by ensuring that any hazardous vapors are captured and removed efficiently, thereby reducing the risk of respiratory issues and other health problems linked to prolonged exposure to these chemicals.

In contrast, mixing chemicals in open spaces can increase the risk of inhalation of dangerous fumes, while storing all chemicals together can lead to reaction risks and difficulty locating specific products in the event of a spill. Ignoring safety measures entirely could expose individuals to a multitude of hazards and is the least safe approach to working with chemicals in a salon environment.
