Millions of workers in the construction industry work on scaffolds. Protecting these workers from scaffold-related incidents can prevent injuries and deaths attributed to falls from scaffolding each year. Scaffold incidents causing injury or death to workers is often the result of either the planking or support giving way, by the worker slipping, the absence of fall protection, or being struck by a falling object. These incidents can be avoided by compliance with OSHA standards.

  • Construction. OSHA Alliance Program. This is one of OSHA's Strategic Management Plan Focus Areas.
  • Construction. OSHA. Construction can be a safe occupation when workers are aware of the hazards, and an effective Safety and Health Program is used. This eTool contains information that helps workers identify and control the hazards that cause the most serious construction-related injuries. Also available in Spanish.
  • Scaffolding. OSHA. Provides illustrated safety checklists for specific types of scaffolds. Hazards are identified, as well as the controls that keep these hazards from becoming tragedies.

Scaffolding hazards are addressed in specific standards for the construction industry.

OSHA Standards

This section highlights OSHA standards, preambles to final rules (background to final rules), Federal Register notices (rules, proposed rules), directives (instruction to OSHA staff), and letters of interpretation (official letters of interpretation of the standards) related to scaffolding.

  • 1926 Subpart M, Fall Protection
  • For additional information on specific state plans or other general standards, see the general industry Standards section.
State Standards

There are twenty-eight OSHA-approved State Plans, operating state-wide occupational safety and health programs. State Plans are required to have standards and enforcement programs that are at least as effective as OSHA's and may have different or more stringent requirements.

Preambles to Final Rules

Federal Register Notices

  • Safety Standards for Scaffolds Used in the Construction Industry. Final Rules 61:46025-46075, (August 30, 1996). Reports that although specific accident ratios cannot be projected for the estimated 3.6 million construction workers currently covered by subpart L, estimates that of the 510,500 injuries and illnesses that occur in the construction industry annually, 9,750 are related to scaffolds.
