ANSI A92.20 Compliance Checklist for Aerial Lift Owners (2026 Update)

ANSI A92.20 is the current standard for the design, calculation, safety requirements, and test methods of mobile elevating work platforms — including all scissor lifts and boom lifts sold in North America after 2020. If you own or operate aerial lifts, here's exactly what compliance looks like in 2026.

1. Annual inspection (mandatory)

Every aerial lift must receive a documented annual inspection by a qualified technician. The inspection covers structural, hydraulic, electrical, control, and safety systems. The dated inspection report stays with the lift and is the first thing Cal/OSHA or any inspector will ask for.

• Structural welds and scissor stack
• Hydraulic cylinders, hoses, fittings — pressure test under load
• Control system and emergency lowering valve function
• Tilt sensor calibration and alarm function
• Guardrail integrity, gate latch, mid-rail spacing
• Battery state of health (electric units) / fluid levels (rough terrain)
• Tire condition and pressure
• Decals — capacity, warning labels, ANSI compliance label

2. Frequent inspection (every 3 months or 150 hours)

Between annual inspections, every lift requires a frequent inspection at 3-month or 150-hour intervals, whichever comes first. This is documented but shorter than the annual.

3. Pre-operation inspection (every shift)

The operator must inspect the lift before every shift. ANSI A92.24 (the operator standard, which works alongside A92.20) requires a documented checklist. Items include:

• Walk-around for damage, leaks, missing decals
• Tire pressure and condition
• Battery charge state
• Control function test — drive, lift, lower, emergency stop
• Guardrails and gate latch
• Operator manual present at platform

4. Operator training and certification

Every operator must be trained on the specific class and model of lift they operate. Training must cover classroom theory plus hands-on practical evaluation. Training is required:

• Before first use of a new lift class
• Every 3 years (recertification)
• After any incident or near-miss
• When changing employers or jobsites with different lift classes

5. Site risk assessment

A92.20 introduced a formal site risk assessment requirement that goes beyond the older A92.6 standard. Before each job, the operator or supervisor documents:

• Ground conditions and slope
• Overhead hazards (power lines, structures)
• Wind speed (for outdoor work — most slab lifts derate above 28 mph)
• Pedestrian traffic and barricading needs
• Load chart compliance for the planned work

6. Load testing (5-year structural)

Every aerial lift requires a structural load test at 5-year intervals (or per manufacturer recommendation). This is more involved than annual inspection and typically requires the lift to be sent to a qualified service facility. Don't skip this — it's the most common citation in Cal/OSHA aerial lift audits.

7. Modification and repair documentation

Any structural or safety-system repair must be documented with OEM parts and a re-inspection. Aftermarket modifications are restricted — adding load to the platform, custom guardrails, or unauthorized counterweights voids the ANSI compliance status of the lift.

Quick compliance checklist

• Current annual inspection report on file
• Frequent inspection log (every 3 months / 150 hours)
• Daily pre-op checklists for every shift
• Operator training certificates current (3 years)
• Site risk assessment documented per job
• 5-year load test current
• All decals legible — capacity, ANSI label, warnings
• Operator manual at the platform
