Hire an Occupational Hygiene and Safety Technician OHST Staffing

Hire an Occupational Hygiene and Safety Technician (OHST)

3P Safety Staffing places BCSP-credentialed Occupational Hygiene and Safety Technicians (OHSTs) on general industry roles in 48 hours or less. OHST is the general-industry-focused credential in the BCSP family. It requires 3 years of professional safety experience where safety is the primary responsibility (50%+ of time).

Candidates must also pass the OHST examination. The exam covers OSHA 1910 general industry standards, industrial hygiene fundamentals, ergonomics, hazard communication, and machine safety. It also covers electrical safety, respiratory protection, hearing conservation, and general industry-specific risk management.

OHST-credentialed pros typically work as Plant Safety Specialists, Manufacturing Safety Coordinators, Distribution Center Safety Leads, and Junior EHS Managers. Others serve as Industrial Hygiene Technicians or Project Safety Officers, supporting senior CSP-credentialed leadership in general industry operations. OHST is the credential commonly specified for general-industry safety roles where CHST (construction-focused) would not be the right match.

Founder Patrick Salazar is a BCSP member; in the field since 2005 — NCCCO Mobile/Tower/Inspector/Lift Director, OSHA 500 instructor. OHST is the general-industry counterpart to CHST — 3 years of professional safety experience in general industry plus examination. Every OHST we place has documented prior general industry work that matches your facility profile.

Every OHST 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 manufacturing plants (automotive, aerospace, appliance, electronics, metal fabrication) and processing operations (food and beverage, chemical, pharmaceutical). It also covers distribution centers and warehousing, healthcare facilities, and general industry adjacent to construction scope.

BCSP OHST Eligibility, Examination & Renewal

The framework below distinguishes OHST as the general-industry-specific credential.

• BCSP OHST eligibility — 3 years of professional safety experience where safety is the primary responsibility (50%+ of time). High school diploma or higher education is the baseline. Note: bachelor’s degree NOT required.
• OHST examination — computer-based test covering OSHA 1910 general industry standards. Plus industrial hygiene fundamentals, ergonomics, hazard communication, and machine safety. Also tested: electrical safety, respiratory protection, hearing conservation, recordkeeping, and general industry-specific risk management.
• OHST renewal — every 5 years. It takes 25 recertification points, earned through continuing education, training delivery, publication, professional activity, or new credentials.
• BCSP code of ethics — OHST designation requires adherence to BCSP code.
• BCSP verification — every OHST is verifiable at bcsp.org by name and credential number.
• OHST credential path — many holders pursue CSP once they add experience and meet the bachelor’s degree requirement. OHST counts as an intermediate credential for CSP eligibility.
• EM 385-1-1 SSHO qualification — OHST is one of the qualifying credentials for USACE SSHO designation. It pairs with EM 385 training and 5+ years federal construction experience. Less common for OHST than CHST due to general industry focus.
• OSHA recognition — OSHA lists OHST among recognized BCSP credentials for federal contracting and various OSHA program eligibility.
• Insurance carrier recognition — most workers compensation carriers and broker loss control programs recognize OHST. It fits mid-level general industry safety roles.
• State plan OSHA recognition — Cal/OSHA, NC OSH, MIOSHA, and other state plans accept OHST credential.
• Federal agency recognition — DCMA, DOE 10 CFR 851 program, NASA STD-8719 reference BCSP credentials.
• Cross-credential pairings — OHST often pairs with STS or SMS (Safety Management Specialist). Some pros hold both OHST and CHST for cross-vertical work.

OHST Placement Process — Intake to Mobilization

OHST placements typically run mid-tier general industry safety engagements.

• Step 1 — Discovery call (30 minutes). We confirm role scope — Plant Safety Specialist, Manufacturing Safety Coordinator, Junior EHS Manager, IH Technician, or Project Safety Officer. We also cover facility type and operations, customer or owner relationship, and expected duration. Then: bilingual needs, in-house EHS team structure, bargaining unit status, and any added certifications.
• Step 2 — Roster match (within 24 hours). Narrow to OHST-credentialed candidates with general industry vertical match. OHST roster segmented by scope — automotive, aerospace, food and beverage, chemical, healthcare, distribution, metal fabrication.
• Step 3 — Proposal package. You get a resume, BCSP OHST credential number, and OSHA 30 General Industry card. We include evidence of added certifications (LOTO authorized employee trainer, PIT trainer, NFPA 70E qualified worker, etc.). The package closes with prior facility references, named former direct supervisors included, and the all-inclusive rate.
• Step 4 — Optional interview. 20 minutes phone or video. Most clients do this. Resolves scope-match concerns before mobilization.
• Step 5 — Selection, paperwork, badging. Background check, drug screen if required, facility badging, IT account provisioning for EHS management system if applicable.
• Step 6 — Day-one mobilization. The OHST arrives with PPE and completes facility-specific orientation. They review open citations and CAPs. Next comes a production floor walk with operations leadership. Then the OSHA 300 log and incident history. Day one is recon; day three is operating.

Standard timing: 24-hour proposal, 72-hour mobilization for in-region, 96 hours for relocation. Federal contractor manufacturing (DCMA-overseen) can add 5-7 days for clearance verification.
