Before using any pneumatic power tool, what must be done to the air hose
connection?
A. Lubricate the coupler with thick grease
B. Verify a safety clip or wire is installed across the coupling
C. Wrap the entire connection tightly with electrical tape
D. Disconnect the compressor regulator valve completely
, 🟢 B. Verify a safety clip or wire is installed across the coupling
🔴 Explanation: Safety clips or retaining wires prevent accidental disconnection, which
can cause the hose to whip violently under high pressure.
On a construction drawing, what type of line is used to show a feature or edge that
is hidden from view?
A. Solid line
B. Chain line
C. Dashed line
D. Break line
🟢 C. Dashed line
