ADEQ Wastewater Collections 1 Practice Test

Keeping chlorine cylinders in a clean, dry location is essential because chlorine is a toxic, corrosive gas and the cylinder valves and fittings are highly vulnerable to moisture and contaminants. A dry, clean space helps prevent rust and corrosion on the cylinder and regulator, preserves valve seals, and reduces the likelihood of moisture reacting with released chlorine. For best practice, store cylinders upright and secured so they cannot tip, and keep protective caps on when they’re not connected to equipment to shield the valve. Storing below ground level can lead to dangerous gas buildup and moisture exposure; storing on their side increases the risk of valve damage and leaks; and leaving protective caps off leaves the valve exposed to damage.
