Final answer:
The incorrect statement on Alana's poster likely is 'Never add disinfectant to water when diluting,' which should be changed to 'Always add disinfectant to water when diluting' to align with safe handling practices.
Step-by-step explanation:
The statement among the options given by Alana that could potentially be incorrect and need placement in the opposite column is: a) Never add disinfectant to water when diluting. According to standard safety protocols, it's important to add the disinfectant to water when diluting, not the other way around. This practice is similar to diluting acids, where the acid should be added to the water to prevent splashing and exothermic reactions that could cause harm. Therefore, the correct guidance should be "Always add disinfectant to water when diluting." The other statements listed are correct and should remain in their current columns:
- b) Always wear gloves and safety glasses.
- c) Never place any disinfectant in an unmarked container.
- d) Always keep the SDS on hand for the disinfectants you use.
