Why should employees read labels before using disinfectants?

Reading labels before using disinfectants is crucial because these labels provide essential information that ensures both effectiveness and safety during use. The correct concentration, contact time, and necessary safety procedures are outlined on these labels to guide employees in how to properly use the disinfectant.

Using the right concentration is vital, as too weak of a solution may not effectively kill pathogens, while too strong could pose unnecessary risks to health and materials. Contact time, or the duration that the disinfectant needs to remain wet on a surface to be effective, is equally important; if the disinfectant is not allowed to sit for the specified amount of time, it may not achieve its intended disinfecting capabilities. Additionally, safety procedures, such as recommended personal protective equipment (PPE) and proper ventilation, are critical to protect the user from potential exposure to harmful chemicals.

The other options may contain elements that could be useful in various contexts, but they do not directly address the primary rationale for reading labels to ensure effective and safe use of disinfectants. Therefore, understanding the information provided on the label is key to maintaining a safe and hygienic environment.
