"Every year, thousands of construction workers don't make it home. Most of those incidents were preventable."

Construction is one of the most hazardous industries in the country. Compliance alone doesn't keep workers safe — culture, training, and on-site leadership do. That's where 3L Safety & Security comes in. We provide the staffing and training infrastructure your jobsite needs to operate without incident.

Safety Staffing &
Training That Works

Site Safety Staffing

Qualified safety officers and supervisors placed directly on your jobsite. We embed with your crew — not just audit from a clipboard.

Safety Training Programs

OSHA compliance, hazard recognition, fall protection, and more. Custom-built for your team and your specific site conditions.

Safety Program Development

Don't have a safety program? We build one from the ground up — documented, defensible, and designed to actually be used in the field.

Incident Investigation

When something goes wrong, we help you understand why — and put systems in place so it doesn't happen again.

Compliance & Audit Support

OSHA inspections and audits don't have to be a scramble. We help you stay ready — and stay compliant — year-round.

Security Staffing

Site access control, perimeter security, and after-hours protection. Construction sites are targets — we keep yours secure.

Built by People Who've
Worked the Site

3L Safety & Security was founded by professionals with over 30 years of hands-on construction safety experience. We're not a consulting firm that visits once and sends a report. We're operators. We've been on the scaffold. We know what a toolbox talk actually needs to say.

We're a startup — but we're built on a foundation of deep industry knowledge, real relationships, and a simple belief: every worker deserves to go home safe.

  • 30+ years combined industry experience
  • Specialists in commercial and industrial construction safety
  • OSHA-trained and field-tested personnel
  • Available for short-term placements and long-term contracts
  • San Diego based — available regionally

We've Seen
What Goes Wrong

Most safety problems aren't surprises. They're the result of skipped steps, undertrained crews, and gaps in oversight that nobody caught in time. We close those gaps before they become incidents — and before they become liability.

Our people don't just know the regulations. They know how to talk to a crew at 6am, how to enforce a standard without shutting down a site, and how to build a safety culture that outlasts the contract.

Trusted by the
People on the Ground

"Having a dedicated safety officer on-site changed the culture of our crew within weeks. The team started looking out for each other in ways we hadn't seen before." — General Contractor, San Diego
"We brought them in after an OSHA citation. They didn't just fix the paperwork — they fixed the underlying problem. Haven't had an issue since." — Project Manager, Commercial Build
"30 years of experience doesn't just show up on a resume. It shows up in how they talk to workers, how they handle pressure, and how they prevent the things that never make it into a report." — Construction Owner, Regional Contractor
