Tower Inspection Procedures Flashcards

During an inspection, what should be checked about the diagonal and horizontal braces?

Answer: That they are all present, correctly positioned, and securely locked into place

All braces must be present as specified in the manufacturer's instruction manual, correctly positioned (diagonals in the right pattern), and securely locked with all clips or locks fully engaged. Missing or loose braces significantly reduce stability.

What should be inspected regarding the platforms and decking of a tower scaffold?

Answer: That they are fully boarded, free from defects, wind locks engaged, and trapdoors functional

Platforms must be fully boarded with no gaps, wind locks or clips engaged to prevent uplift, trapdoors functioning correctly, and boards free from splits, cracks, warping, or excessive wear that could compromise their strength.

When inspecting castors, what specific checks should be made?

Answer: That they are correctly fitted, not damaged, brakes fully functional, and all brakes applied during use

Castors must be checked for correct fitting to the frame, damage to the wheel or housing, full brake functionality (brakes must hold firmly), and that all brakes are applied when the tower is in use. A damaged or non-functioning brake is a critical defect.

What does a visual check for 'plumb' involve during a tower inspection?

Answer: Checking that the tower is vertically straight and not leaning to one side

Checking for plumb means verifying the tower is vertically upright and not leaning in any direction. A tower that is out of plumb has a shifted centre of gravity, increasing the risk of overturning. A spirit level can be used to verify.

What should be checked about the toeboards during a tower scaffold inspection?

Answer: That they are at least 150mm high, securely fitted on all open sides, and free from damage

Toeboards must be at least 150mm high, fitted on all open sides of the platform, securely fixed, and in good condition without splits or damage. They prevent tools and materials from falling off the platform edge onto people below.

After an inspection reveals a tower is safe to use, how should this be communicated?

Answer: By completing and displaying the inspection record/tag and briefing relevant workers

The completed inspection record should be available on site (often displayed on or near the tower using a scaffold tag system), and relevant workers should be briefed on the tower's status and any conditions of use.
