positive closure when the system is off, locate the entire chemical delivery line below the level of
the chemical inlet. An example of this is shown in Figure 4.

Guarding Against Leaks
All personnel who may work with the chemical system (e.g., chemical system manufacturer,
chemical system supplier, chemical supplier, operator, maintenance personnel) should be vigilant
in observing for leaks in the system. When connecting, or reconnecting chemical lines, whether at
installation, after taking samples, or when replacing components, at a minimum ensure that:
1. the proper components are used,
2. all connections are the proper fit, and
3. all components are securely connected.
CAUTION 2 : Injury and Damage Hazards
—Chemicals leaking from a chemical system
may be corrosive or toxic. Such chemicals can injure personnel and damage equipment.
• Use care when connecting chemical lines.
• Inspect regularly for leaks.
