Hire a Construction Health and Safety Technician CHST Staffing

Hire a Construction Health and Safety Technician (CHST)

3P Safety Staffing places BCSP-credentialed Construction Health and Safety Technicians (CHSTs) onto construction projects in 48 hours or less. CHST is the construction-specific credential in the BCSP family. It requires 3 years of documented construction safety experience where safety is the primary responsibility. Candidates must also pass the CHST examination. The exam covers OSHA 1926 standards, fall protection, excavation, scaffolds, steel erection, cranes, and hazardous substances. It also covers electrical safety, fire prevention, and construction-specific risk management.

CHST-credentialed practitioners typically work as Site Safety Managers on mid-sized commercial and multifamily projects. Many serve as Safety Coordinators on larger jobs, supporting an SSM or CSP. Others work as Safety Officers on specialty trade contractor crews. You will also find them as Construction Safety Technicians on industrial construction and Project Safety Leads on infrastructure and civil work. CHST is the credential commonly written into prime contractor bid requirements for “safety lead” roles on commercial construction projects.

Founder Patrick Salazar is a BCSP member; in the field since 2005 — NCCCO Mobile/Tower/Inspector/Lift Director, OSHA 500 instructor. CHST is the construction-specific BCSP credential — 3 years documented construction safety experience required. Every CHST we place has documented prior construction project history that matches your scope category.

Every CHST on our roster is verifiable at bcsp.org by name and credential number. We share the credential number in every proposal package. Placement history covers commercial vertical construction (mid-rise office, retail, hospitality), multifamily and high-density residential, and healthcare construction. It also covers federal construction with USACE EM 385 overlay, infrastructure and civil work, and industrial construction projects.

CHST Placement Process — Intake to Mobilization

CHST placements typically run mid-tier construction safety engagements.

• Step 1 — Discovery call (30 minutes). We confirm role scope — SSM, Safety Coordinator, Project Safety Officer, or Safety Lead on a specialty trade. We also cover project type and dollar value, customer or GC relationship, and anticipated duration. Language needs come next; English/Spanish bilingual is a common ask. Finally: federal vs commercial designation and required additional certifications (Subpart M, P, EM 385).
• Step 2 — Roster match (within 24 hours). Narrow to CHST-credentialed candidates with construction vertical match. CHST roster segmented by scope category — commercial vertical, multifamily, healthcare, federal, infrastructure, industrial.
• Step 3 — Proposal package. You get a resume, BCSP CHST credential number, and OSHA 30 Construction card — plus the EM 385 certificate if federal. We include evidence of competent-person designations (Subpart M, P, L, R, AA, Z). The package closes with prior construction project references, named former GC superintendents included, and the all-inclusive rate.
• Step 4 — Optional interview. 20-minute phone or video. Most clients do this; federal clients always interview. Resolves scope-match concerns before mobilization.
• Step 5 — Selection, paperwork, badging. Background check, drug screen if required, federal badging if applicable, GC-required pre-task orientation review.
• Step 6 — Day-one mobilization. CHST arrives with PPE, completes site-specific orientation, signs SSHO designation if federal scope, meets superintendent and PM, joins the morning huddle. Day one is observation; day two is operating.

Standard timing: 24-hour proposal, 48-hour mobilization for in-region, 72 hours for relocation. Federal badging can add 5-15 days depending on installation.

We have mobilized to FEMA-declared events in coastal NC, the Florida panhandle, and the Texas Gulf Coast.

Frequently Asked Questions About Hiring a Construction Health and Safety Technician (CHST)

What is a Construction Health and Safety Technician (CHST)?
CHST is the construction-specific credential issued by the Board of Certified Safety Professionals (BCSP). Eligibility requires 3 years of professional safety experience in construction, with safety as the primary responsibility (50%+ of time). Candidates must also pass the CHST examination. The exam covers OSHA 1926 standards, fall protection, excavation, scaffolds, steel erection, cranes, hazardous substances, and construction-specific risk management.

How is CHST different from CSP?
CHST is construction-focused and requires 3 years of construction safety experience plus a high school diploma baseline. CSP is the senior BCSP credential requiring a bachelor’s degree plus 4 years of professional safety experience plus an intermediate credential (often CHST). CHST is the typical credential for site safety lead on mid-sized commercial construction. CSP is the typical fit for senior SSM on larger projects or corporate EHS Director roles.

Does CHST qualify someone as a USACE EM 385-1-1 SSHO?
Yes — CHST is one of the qualifying credentials for SSHO designation under EM 385-1-1. It must be paired with the required 40-hour EM 385 training and 5+ years of documented construction safety experience. Many federal projects accept CHST plus EM 385 for SSHO designation; senior or higher-value federal projects may prefer CSP.

Can I verify the CHST credential of a candidate you propose?
Yes. Every CHST credential is verifiable at bcsp.org by name and credential number. We include the credential number in every proposal package; you can verify directly with BCSP.

What does hiring a CHST cost?
All-inclusive hourly rates run $75-$95 for a recently-credentialed CHST and $95-$125 for 5-10 years post-credential. Senior CHSTs with 10+ years run $115-$150. Subpart M competent person with fall protection specialty runs $105-$140. EM 385 SSHO for federal scope runs $115-$160, and federal Secret clearance runs $135-$180. Bilingual coverage adds $5-$8 per hour.

Can you cover federal construction projects requiring SSHO designation?
Yes. Our federal sub-roster includes CHSTs with current EM 385 40-hour training plus annual 8-hour refresher, plus 5+ years documented federal construction safety experience. Many are former military with DD-214 documentation supporting CAC and Secret clearance eligibility through prime contractor sponsorship.
