Which of the following is NOT a safety standard for chlorine storage buildings?

Storing equipment unrelated to chlorine within the building is not a safety standard for chlorine storage facilities. Chlorine is a hazardous chemical that requires specific handling and storage protocols to ensure safety. Keeping the storage area free of unnecessary equipment helps minimize the risk of chemical reactions, contamination, or accidental releases. The presence of unrelated equipment can complicate emergency responses and create additional hazards, which is why it does not adhere to safety standards designed for chlorine storage.

In contrast, the other options reflect important safety measures. Continuous fan operation helps maintain air circulation and limits the accumulation of chlorine gas, ensuring that any leaks can dissipate. Screened vents provide a method of ventilation that helps manage gas buildup while preventing the entry of foreign objects and pests. Availability of emergency equipment such as eyewash stations and proper protective gear is essential for immediate response in case of an incident, allowing for quick action to protect personnel in the event of a chlorine release or exposure.
