Field checklist

Ask Foreman

Hey boss, I’m checking hand tools & safety: What's the difference between red, green, and yellow aviation snips? I found the likely issue and want to verify the next step before I lock it in. Do you want me to adjust it now or check the drawing/detail first?

Verify before acting

Use this as training guidance. The foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, and AHJ/code requirements always control the final answer.
