When using disinfectants, what order must be followed in terms of water addition?

1. Add disinfectant to water

2. Add water to disinfectant

3. Mix equally before use

4. None of the above

The correct answer is: Add water to disinfectant

The correct approach when using disinfectants is to add water to disinfectant. This method is crucial because adding disinfectant to water can create a more concentrated solution than intended, which can potentially affect the effectiveness and safety of the disinfectant. When water is added to disinfectant, it allows for a gradual dilution of the active ingredients, ensuring that the mixture adheres to the manufacturer's instructions for proper use and effectiveness. In practice, many disinfectants are formulated to be effective within a specific dilution ratio, and following the correct sequence protects the integrity of the solution and achieves optimal disinfection. Additionally, this method minimizes the likelihood of splashing concentrated disinfectant, which can pose safety hazards.
