When working with scaffolds, several safety measures should be followed to ensure worker safety. Here's a summary of key points:

• Competent Supervision: Erection, moving, dismantling, or alteration of scaffolds must be supervised by a competent person qualified in these activities [1].
• Trained Personnel: These activities should only be performed by experienced and trained employees selected by the competent person [1].
• Weather Conditions: Work on scaffolds is prohibited during storms or high winds unless a competent person determines it's safe and employees are protected by personal fall arrest systems or wind screens 1, 2. Wind screens should only be used if the scaffold is secured against anticipated wind forces 1, 2.
• Surface Conditions: Employees should not work on scaffolds covered with snow, ice, or other slippery materials, except when removing such materials 1, 2. If there is snow or ice, it must be removed and the planking sanded to prevent slipping [2].
• Load Control: When hoisting loads onto or near scaffolds, use tag lines or equivalent measures to control the loads 1, 2, 4.
• Platform Maintenance: Debris should not be allowed to accumulate on platforms 1, 2, 4.
• Proper Equipment: Makeshift devices like boxes and barrels shall not be used to increase the working level height 1, 2. Ladders should not be used on scaffolds to increase the working level height, except in specific situations where the scaffold and ladder are properly secured 1, 2.
• Platform Deflection: Platforms shall not deflect more than 1/60 of the span when loaded 1, 2.
• Welding Safety: When welding from suspended scaffolds, use an insulated thimble to attach each suspension wire rope to its hanging support, and cover the suspension wire rope with insulating material [3].
• Regular Inspections: Frequent and regular inspections of job sites, materials, and equipment must be made by competent persons [4]. All parts and fasteners should be thoroughly inspected as often as possible for damage, corrosion, loose or missing parts, improper assembly, and wear [4].
• Fall Protection: Always use fall-arrest equipment when using suspended scaffolds [5]. Each person on a suspended powered scaffold must be attached to a fall-arrest system at all times [6].
• Load Limits: Do not overload scaffolds. The total combined weight of workers and materials shall not exceed the rated working load [4].
• Power Line Safety: Maintain a safe clearance between scaffolds and power lines [7].
• Falling Object Protection: Implement measures to protect workers below from falling tools, materials, or equipment [8].
• Wire Rope Safety: Use only wire rope and attachments as specified by the hoisting machine manufacturer. Inspect wire rope during each ascent and descent [6].
• Training: Users must be trained on how to safely operate equipment and handle emergency situations [5].
• Scaffold design: Scaffolds and their components shall be capable of supporting without failure at least four times the maximum intended load [2].
• Rolling Scaffold stability: The height of a rolling scaffold should not be more than 3 times the smallest dimension of the scaffold's base [9].

It is important to be aware of the hazardous working environment when using scaffold equipment and to be properly trained in its use and rigging [4].
