Describe the requirements for platform construction for scaffolds
What will be an ideal response?
All platforms must be fully planked and the planking must be placed so that gaps between units is no more than one inch. The one-inch requirement cannot be exceeded unless an employer can establish that a larger gap is necessary in order to fit around supporting structures or other similar circumstances. When the one-inch rule is exceeded, individual planking units must be kept as close together as possible and may not exceed 9½ inches between the platform and upright supports or guardrails.
