What must a licensee do when mixing or touching disinfectant solutions?

When mixing or touching disinfectant solutions, wearing gloves is essential for several reasons. Disinfectants often contain strong chemicals that can irritate the skin or cause allergic reactions. By using gloves, the licensee protects their skin from direct contact with these potentially harmful substances, preventing skin irritations or other negative health effects. Furthermore, gloves help maintain a hygienic environment by preventing contamination from the skin to the disinfectant solutions, ensuring that they remain effective and safe for use.

While wearing safety goggles, a mask, or washing hands can also be important in certain contexts, none provide the specific protective barrier that gloves do against direct contact with harsh disinfectants. Gloves are the primary form of protection against skin exposure to these chemicals, which is why this choice is the most appropriate in this scenario.
