Roller-type felt laying machines should be:

Roller-type felt laying machines should be:

• A. Locked and stationary on the roof
• B. In motion across the roof
• C. On the ground only
• D. Controlled by crane

Answer: (A)

Securing rolling equipment on a roof is essential to prevent uncontrolled movement. A roller-type felt laying machine sits on the roof and can slide or roll due to gravity, wind, or operator motion. Locking it so it stays stationary during operation keeps the machine from shifting out of alignment and protects workers from being struck or knocked off the roof. When you need to reposition, release the lock, move it, then re-lock in the new position. It shouldn’t be operated in motion across the roof, and it isn’t limited to being on the ground or controlled by crane for normal use.
