TL;DR - The Essentials
✅ Check Your Status:
- Use 2023-2025 injury data to calculate DART (Days Away/Restricted/Transfer)
- High DART (> national avg) = Primary list; moderate = Secondary
- Lists release mid-March; inspections start April for 2 years
❌ Risks If Listed:
- Unannounced audits anytime: full site reviews
- Average $47K downtime + fines per inspection
- Phoenix focus: I-10 projects under extra scrutiny

Why SST Hits Phoenix Construction Hard in 2026
OSHA's Site-Specific Targeting (SST) program is designed to identify and inspect the most dangerous workplaces in America. For construction firms (NAICS 23), it's a data-driven targeting system that uses your electronic injury/illness submissions to automatically flag high-risk sites. If you're on the list, expect unannounced inspections for the next 2 years.
The Urgency Now: March 2 Feeds Directly Into SST
Timeline: March 2 deadline → OSHA compiles data → SST lists released ~March 15 → Inspections start April 1 and continue for 2 years
The Connection: Bad data in your March 2 submission = auto-flag on SST list. With AZ construction permits steady but labor tight, an audit could delay bids and cost contracts during the spring boom.
🎯 Phoenix Angle:
- •Weather impact: Rainy February = spike in slip/trip incidents → inflated DARTs
- •Growth hotspots: Valley semiconductor builds, I-10 expansion = high visibility for OSHA
- •Enforcement priority: OSHA Southwest plans +25% more audits Q2 2026, targeting DART offenders
💰 Cost Breakdown: What SST Listing Really Means
Direct Fines
Average per serious violation. Most SST inspections find 3-5 violations = $50K-$80K in fines
Downtime Costs
Per inspection day. Average SST audit = 2-3 days. Stop-work orders can extend to weeks
Contract Impact
Duration on SST list = 2 years of potential audits. GCs see your status = bid rejections
Real AZ Example: A Costly Lesson
Mesa General Contractor (150 employees): 2024 DART of 2.8 from unreported back strains and equipment incidents. Landed on 2025 SST Primary list. Result?
"We fixed it post-listing, but the damage was done. Two years of audits destroyed our Q2-Q3 momentum. I wish we'd caught the DART calculation errors before March 2024 submission." - Owner
How to Check If You're on the 2026 SST List
OSHA uses your ITA submission data to calculate DART and assign Primary (high-risk) or Secondary (moderate-risk) status. Calculate NOW before March 2 to fix errors.
Gather Your Historical Data
You need: 2023, 2024, and 2025 injury logs
📊 What OSHA Looks At:
SST uses 3 years of data to calculate your DART rate. They're pulling from your 2024 submission (2023 data), 2025 submission (2024 data), and your upcoming March 2 submission (2025 data).
Translation: If you had a bad 2023 or 2024, those years still count. But you can improve by getting 2025 data perfect.
What to Compile:
- OSHA Forms 300/300A for 2023, 2024, 2025
- Total hours worked by all employees (from payroll) for each year
- Cases with days away from work (Column H on Form 300)
- Cases with job transfer or restriction (Column I on Form 300)
Common Phoenix Mistake: Weather-Related Misclassification
February 2025's wet weather = spike in slips/trips. If you classified a slip as "days away" when it was actually just "medical treatment only" (not recordable), your DART is artificially inflated. Review wet-weather incidents NOW before submitting.
Calculate Your DART Rate
The formula that determines your SST fate
📐 The DART Formula:
(Number of DART Cases × 200,000) ÷ Total Hours Worked
200,000 = OSHA's standardization for 100 full-time employees working 1 year
What Counts as a "DART Case"?
- ✓Any injury/illness that results in days away from work
- ✓Any injury/illness with restricted work activity (light duty)
- ✓Any injury/illness requiring job transfer
🧮 Example Calculation (Phoenix Roofing Crew):
2025 Data:
- • 3 falls requiring days away
- • 2 back strains with restricted duty
- • 1 heat illness with job transfer
- • Total DART Cases = 6
- • Total hours worked = 250,000 (from payroll)
DART = (6 × 200,000) ÷ 250,000 = 4.8
🚨 4.8 is DOUBLE the construction average (2.0) = Guaranteed SST Primary List
Compare to National Average
Determine if you're Primary, Secondary, or Safe
Safe Zone
Below national avg. Not on SST list. Continue best practices.
Secondary List
Moderate risk. Random audits possible. Improve now.
Primary List
High risk. Guaranteed audits. Urgent action needed.
📊 2026 Construction Industry Benchmarks:
National Averages (Construction NAICS 23):
- • General contractors: 2.0 DART
- • Heavy/civil engineering: 1.8 DART
- • Specialty trades: 2.2 DART
- • Roofing: 3.1 DART (highest)
Phoenix Metro Trends (2025 Data):
- • 15% higher DARTs Feb-Mar (weather)
- • I-10 expansion firms: 2.4 avg
- • Semiconductor builds: 1.9 avg (newer safety tech)
- • Residential crews: 2.6 avg
What OSHA Does With Your DART:
- 1.Calculates 3-year average: (2023 DART + 2024 DART + 2025 DART) ÷ 3
- 2.Compares to industry: Above avg = Primary; moderate = Secondary
- 3.Publishes lists mid-March: Your firm name becomes public on OSHA's SST website
- 4.Schedules inspections: Primary = guaranteed audit starting April; Secondary = random selection
Understand Primary vs. Secondary Lists
What each designation means for your business
Primary List (High-Risk)
Who's on it:
Firms with DART rates significantly above industry average (typically >3.5 for construction)
What happens:
- • Guaranteed inspection within 12 months
- • Comprehensive safety audit (wall-to-wall)
- • Multiple follow-ups likely
- • Public listing on OSHA website
⚠️ Critical Impact:
GCs check SST lists before awarding bids. Being on Primary list = automatic disqualification for many projects.
Secondary List (Moderate-Risk)
Who's on it:
Firms with DART rates moderately above average (2.0-3.5 for construction)
What happens:
- • Random selection for inspections
- • Lower priority than Primary
- • ~30% chance of audit in 2-year cycle
- • Still publicly listed
💡 The Opportunity:
Secondary = improve now to drop off next cycle. Fix classification errors, enhance safety programs.

Prep Tips to Drop Your Score & Survive Inspections
Whether you're trying to stay off the list or preparing for inevitable audits, these strategies work for Phoenix construction teams.
1. Fix Data Errors Before March 2 Submission
The most immediate way to lower your DART: Review 2025 logs for misclassifications
Common Errors to Check:
- Over-classification: Minor slips marked "days away" when it was just first aid
- Duplicate entries: Same incident logged twice (e.g., initial + follow-up)
- Wrong dates: Incident date vs. when days away started
- Missing context: Restricted duty counted when worker refused, not medically required
Phoenix-Specific Fixes:
- Feb weather slips: Verify if medical treatment required days away vs. just bandage
- Heat stress: If hydration-only treatment, not recordable
- Aggravated pre-existing: Old injury flare-up may not count
⚡ Action: Re-submit corrected Form 300 via ITA if you find errors (before March 2)
2. Lower DART Proactively for Future Cycles
Can't fix past data? Start improving now to drop off list in 2028-2029 cycle
Proven Strategies from Phoenix Firms:
Quick Wins (Implement This Week):
- ✓ Daily safety huddles (5 min pre-shift)
- ✓ Mandatory PPE checks at entry
- ✓ Slip hazard patrols after rain
- ✓ Hydration stations (even in Feb)
Long-Term (Next 90 Days):
- ✓ Digital incident reporting (mobile)
- ✓ Foreman safety training refresh
- ✓ Equipment inspection logs
- ✓ Near-miss tracking program
📊 Real Impact: Scottsdale Electrical (72 Employees)
2024 DART: 3.2 (Secondary List) → Implemented daily huddles + mobile logging → 2025 DART: 1.8 (Off List)
"We dropped 44% in one year. The mobile app caught near-misses before they became recordable incidents." - Safety Director
3. Audit-Proof Your Sites (If You're on the List)
OSHA inspectors will show up unannounced - be ready every single day
What SST Inspections Look Like:
Unlike complaint-based inspections, SST audits are comprehensive. Inspectors arrive unannounced, check EVERY site, review ALL records, interview workers, and look for patterns.
Average duration: 2-3 days. They can issue stop-work orders on the spot.
Documents to Have Ready (Physical & Digital):
- OSHA 300/300A logs (3 years)
- Training certificates (all workers)
- Equipment inspection logs
- Safety program manual
- Incident investigation reports
- Corrective action documentation
Phoenix Pro Tips:
- Job trailer binders: Organized by date, accessible in <2 minutes
- Mobile logs: Show real-time compliance (not just paper)
- Weather protocols: Document rain/heat procedures
- Foreman briefings: Train crew on inspector interactions
4. Phoenix-Specific Prep (Weather & Growth Factors)
Local conditions that inflate DARTs - address them proactively
🌧️ February-March Rain Protocol:
Phoenix's "winter" rain isn't consistent, so crews often ignore protocols. But wet concrete, muddy access roads, and slick scaffolds spike slip/trip incidents 20-30% during Feb-Mar.
Immediate Actions:
- • Non-slip mats at entry points
- • Squeegees for scaffold platforms
- • Boot traction checks daily
- • Delay roof work until dry
Documentation:
- • Weather log in job diary
- • Photos of wet conditions
- • Work stoppage records
- • Protocol compliance sign-offs
☀️ Heat Illness Prep (Even in "Cooler" Months):
Phoenix hits 80°F+ in March-April. Workers coming off cooler Feb weather aren't acclimated. Heat stress cases = recordable if medical treatment beyond hydration.
- Water stations at every site (document refill logs)
- Shade structures for breaks (>80°F)
- Acclimatization protocol for new hires
- Monitor high-risk workers (older, new, medical conditions)
🏗️ High-Profile Project Extra Scrutiny:
If you're working on I-10, Loop 202, or semiconductor campus builds, OSHA pays extra attention. These are political/economic priorities = higher visibility.
⚡ Strategy: Treat these sites as "always under inspection" - no shortcuts, full documentation, daily audits.
Tools for Effortless SST Prep & DART Management
Manual spreadsheets can't catch classification errors or predict SST risk. Here's what modern Phoenix construction firms use to stay off the list:
AI-Powered DART Validation

Frequently Asked Questions
How do I know if I'm officially on the SST list?
OSHA publishes SST lists publicly on their website (~mid-March each year) at osha.gov/enforcement/targeting/sst.
You can search by company name or establishment. But don't wait for the list - calculate your DART NOW using our free calculator to predict status before submission.
⚠️ Once the list is public (mid-March), it's too late to fix 2025 data. The window to correct is NOW (before March 2).
Can I remove myself from the SST list once I'm on it?
Not for the current 2-year cycle (2026-2028). Once you're on the 2026 list based on 2023-2025 data, you remain on it through 2027.
However, you can improve now to drop off the NEXT cycle (released 2028, using 2025-2027 data):
- • Implement safety improvements immediately
- • Track 2026-2027 incidents meticulously
- • Lower DART below industry average
- • Document proactive safety culture
📊 Good news: Firms that improve during SST listing can use it as proof of commitment in future bids.
What if my DART is high due to one bad year (e.g., 2023)?
SST uses a 3-year rolling average, so one bad year can be offset by two good years.
Example:
• 2023 DART: 4.5 (bad year, major project incident)
• 2024 DART: 1.8 (improved)
• 2025 DART: 1.5 (excellent)
• 3-Year Avg: 2.6 (Borderline Secondary - might avoid Primary)
✅ Strategy: If 2023-2024 were bad, make 2025 PERFECT to pull down the average. Every corrected case matters.
Do GCs and clients see the SST list?
Yes, 100%. The SST list is public and searchable. Many GCs now run OSHA SST checks on subcontractors before bid awards.
Impact we've seen in Phoenix:
- • Major GCs have "no Primary List subs" policies
- • Some require proof of DART improvement plans
- • Insurance premiums spike 15-30% if on Primary
- • Secondary List = extra scrutiny but not auto-DQ
🚨 Being on SST list isn't just an OSHA issue - it's a business growth killer.
What if I disagree with my DART calculation or SST placement?
You can request an informal review from OSHA if you believe there are errors in:
- • Data used for calculation (e.g., wrong establishment)
- • DART formula application
- • Industry classification (NAICS code)
Process: Contact your local OSHA area office within 30 days of list publication with documentation supporting your case.
⚠️ However, appeals rarely succeed if your submitted data is accurate. The best defense is getting data right BEFORE March 2 submission.
0 Days to March 2 = Your SST Fate Is Set
The data you submit determines 2 years of potential audits, contract eligibility, and insurance costs. Don't let classification errors put you on the list.
