What to Check First

Ask Foreman

Before this section is pressurized, who is leading the test, what closures need restraint, and where is the exclusion area?

Text to Foreman

Do Not Do This

Do not stand in front of a cap, tighten a moving closure under pressure, or remove anything until the section is confirmed depressurized.

Why This Matters

A failed temporary closure can become a projectile and cause serious injury or major duct damage.

Verify against: project test plan, employer safety procedure, test-equipment instructions, foreman/test lead.
