Safety and Insurance Checklist for Tree Service
PPE, OSHA references, insurance ranges, hazard awareness, and hiring questions for homeowners comparing tree service bids.
PPE requirements
Tree Service should arrive with PPE selected for tree trimming and removal. Expect ANSI-rated eye protection, material-specific gloves, durable boots, hearing protection when saws, grinders, compressors, pumps, or impact tools are used, and head protection where overhead work or suspended materials are present. For this trade, the higher-signal gear is chainsaw chaps or cut-resistant leg protection, helmet with face screen, eye protection, and hearing protection, and climbing saddle, rope system, and fall-arrest or positioning gear when aloft. Crews should keep respirators fit-tested when work can create dust, mold, lead, asbestos, solvent mist, refrigerant vapor, sewage aerosol, pesticide exposure, or other airborne hazards; a loose disposable mask is not a substitute for an assigned respirator. PPE should match the task on that day: climbing, rigging, removals, pruning, stump grinding, crane-assisted lifts, chipper work, and storm cleanup. Ask how the supervisor decides when to upgrade from ordinary gloves and glasses to face shields, arc-rated clothing, fall arrest, chemical cartridges, or mechanical ventilation.
OSHA standards
The main OSHA references for tree service are 29 CFR 1910.266 for logging-type operations where applicable; 29 CFR 1910.269(r) for line-clearance tree trimming near electric utility lines where applicable; 29 CFR 1926 Subpart M (fall protection) and 29 CFR 1926 Subpart X (ladders); 29 CFR 1926 Subpart I (tools), including 1926.300 and 1926.302. Hazard communication under 29 CFR 1910.1200 matters when cleaners, coatings, adhesives, refrigerants, pesticides, fuels, silica-containing dust, or other chemicals are used. Respirator use should connect to 29 CFR 1910.134 or 29 CFR 1926.103 when required. Tree work is not ordinary landscaping. The contractor should control drop zones, climbing systems, rigging loads, chipper feed, traffic, energized-line clearance, and storm-damaged tension wood. Crane-assisted removals add lift planning and communication requirements. Work 6 feet or more above lower levels brings 29 CFR 1926.501 through 1926.503 into fall planning; ladders and scaffolds can add 29 CFR 1926 Subpart X or Subpart L. A credible tree service should be able to name the competent person or qualified worker for the risky part of the job, describe training, identify written plans or permits, and explain how hazards are isolated before work starts.
Insurance minimums
Do not treat any number here as a legal minimum. Insurance and bonding minimums vary by state, city, license classification, contract, payroll, subcontractor use, and whether the pro has employees. For tree service, many residential customers and general contractors commonly ask for commercial general liability around the $1M per occurrence / $2M aggregate range; higher-risk roof, tree, structural, utility, fire-protection, solar, pool, well, septic, or environmental work may be underwritten at $2M to $5M or more. Tree work often needs explicit tree-care coverage; ordinary landscaping insurance may exclude climbing, removals, crane work, utility clearance, or stump grinding. Ask for a current certificate that names the actual trade operations and does not exclude the work you are hiring. Workers' compensation is normally required when state law and worker status trigger it; owners, LLC members, family businesses, and subcontractors may be treated differently by state. Verify active status with the state workers' comp agency when possible. Bonding is separate: license, permit, right-of-way, performance, or payment bonds may be required by a state board, municipality, utility, or prime contract. For state-specific licensing and bonding context, use /license/tree-service-license-in-{state}; replace {state} with the two-letter code, such as /license/tree-service-license-in-oh.

Hazard awareness
Tree Service can create hazards that are easy to miss because the work often happens in familiar rooms, yards, garages, roofs, attics, crawlspaces, or driveways. Hazards include falls from trees, struck-by limbs, barber-chair splits, chainsaw kickback, chipper entanglement, hidden decay, bee or wasp nests, overhead conductors, unstable storm loads, and public traffic under the canopy. Older homes add special concerns: pre-1978 paint can trigger lead controls, legacy materials can be asbestos suspect, and plaster, concrete, brick, mortar, stone, or fiber-cement cutting can trigger respirable crystalline silica controls. Noise, heat, poor lighting, awkward access, sharp debris, temporary cords, weather, and occupant traffic can turn a routine job into a high-risk setup. Good contractors perform a short job-hazard review before tools are unloaded, isolate the work area, preserve emergency shutoffs and exits, use ventilation or wet methods when exposure could spread, and document surprises.
Verification questions
Before approving the estimate, ask direct questions. Who is the safety lead, competent person, or qualified worker for this job? Which OSHA standards or company procedures govern the highest-risk task? What PPE, containment, ventilation, fall protection, lockout, traffic control, or excavation protection will be used at my property? Can you send current insurance, workers' compensation proof or exemption, and any required bond? What conditions will make the crew stop work and call me before continuing? For tree service, add: Will climbers use a documented rope and saddle system or aerial lift?, How is the drop zone barricaded from occupants, sidewalks, vehicles, and service lines?, and Does the insurance certificate explicitly cover tree removal, climbing, and crane or subcontracted work?. Listen for task-specific answers, not slogans. A contractor who explains limits, exclusions, and stop-work triggers is usually safer than one who says every job is routine. Keep the answers with the signed estimate.
