What is the maximum safe withdrawal rate for a chlorine cylinder weighing 150 lbs?

20 lbs
30 lbs
40 lbs
50 lbs

The correct answer is: 40 lbs

The maximum safe withdrawal rate for a chlorine cylinder typically depends on the weight of the cylinder and its design specifications. For a chlorine cylinder that weighs 150 lbs, the recommended safe withdrawal rate is often around 40 lbs per day. This consideration is vital to ensure both safety and effectiveness in the use of chlorine for disinfection and treatment processes. Withdrawal rates that exceed this safe amount can lead to operational issues and increase the risks associated with chlorination, such as encountering insufficient chlorination capacity or even safety hazards due to high-pressure releases. While other options represent lower withdrawal rates, the chosen 40 lbs stands out as the most appropriate balance for effective chlorine management while remaining within safety guidelines.
