Classify an elevated work platform as an OSHA scaffold or an aerial lift to apply the correct subpart

Steps
Check whether the equipment matches the ANSI A92.2-1969 aerial-lift categories referenced in 1926.453 (extensible boom, aerial ladder, articulating boom, vertical tower, or a combination).
If it matches, apply 1926.453 aerial-lift requirements, including tie-off while working from the platform.
If it does not match (e.g., a scissor lift), classify it as a scaffold under 1926.451/1926.452 instead, per OSHA's standing interpretation.
Apply the correct fall-protection method: guardrails as primary protection for scissor-lift/scaffold platforms (PFAS only in specific circumstances), versus body-harness tie-off for true aerial lifts.
Train operators on category-specific hazards (boom extension/tip-over for aerial lifts vs. guardrail integrity/mobility for scissor lifts).
Known gotchas
Scissor lifts are commonly assumed to be 'aerial lifts' but OSHA classifies them as scaffolds -- this affects which fall-protection rule applies.
1926.453 still incorporates the outdated 1969 ANSI equipment list by reference; check whether newer platform types have a specific OSHA interpretation before assuming coverage.
