OSHA treats staffing agencies and host employers as joint employers of temporary workers, and both are responsible for providing a safe workplace — which in practice means the agency delivers general safety training while the host employer delivers the site- and equipment-specific training its own employees receive. Neither party can contract away its obligations; OSHA has stated plainly that an employer cannot avoid its ultimate responsibilities under the OSH Act by requiring another party to perform them.
For employers using contingent labor, the exposure is rarely that nobody trained the worker. It is that both parties assumed the other one had.
What Does OSHA Actually Say About Who Trains a Temporary Worker?
The controlling guidance is OSHA’s Temporary Worker Initiative, launched in 2013 and documented across a series of bulletins covering individual standards. The framework has three parts, and the third is the one employers miss.
First, joint responsibility. Both the staffing agency and the host employer have obligations to the temporary worker, and OSHA can and does cite either or both. Second, a division of labor: TWI Bulletin No. 4 on safety and health training describes the expectation that staffing agencies provide general safety and health training applicable across worksites, while host employers provide training specific to the particular hazards, equipment, and processes at their site. Third — and this is the part that generates citations — the agency has a duty to inquire into conditions at the host site. An agency that places workers without asking what hazards they will encounter has not met its obligation, even if the host trained them competently.
OSHA’s position is that temporary workers must be treated like any other worker in terms of training and protection. If your direct employees get a two-hour equipment orientation before touching a machine, so does the temp. “They are only here for three weeks” is not a recognized exception.
The classification questions that sit upstream of this — whether a worker is a temp, a 1099 contractor, or a gig worker, and what each status implies — are covered in our guide to managing compliance training for a contingent and 1099 workforce. This article assumes the classification is settled and focuses on the OSHA-specific split of duties at the client site.
How Does the Split Work for Specific OSHA Standards?
The TWI bulletins are standard-by-standard, and the split changes depending on how site-specific the standard is. Four examples that cover most contingent placements:
Hazard Communication. TWI Bulletin No. 5 addresses this directly. The staffing agency can deliver generic HazCom instruction — how to read a label, what a safety data sheet is, what the pictograms mean — using a course such as Hazard Communication Awareness. But the host employer must train on the specific chemicals present in the worker’s actual work area and on the site’s written HazCom program, because only the host knows what is in the building. A generic course alone does not satisfy 1910.1200 for either party. The site-specific piece is what our HazCom written program template guide covers.
Powered industrial trucks. Forklift operation is where hosts get cited most often, because the standard requires site-specific evaluation of the operator on the actual equipment and in the actual conditions. Foundational instruction such as Forklift General Safety can come from the agency, but the practical evaluation is a host-site activity and cannot be delegated to a course completion certificate.
Lockout/tagout. Energy-control procedures are inherently machine-specific. General awareness through Electrical Safety and Lockout/Tagout establishes the concept, but authorized-employee training on the host’s specific procedures for specific equipment is the host’s job. A temp who has taken a LOTO awareness course is not an authorized employee at your facility.
PPE and respiratory protection. Hazard assessment drives PPE selection, and hazard assessment is site-specific. The host determines what equipment is required; the agency may deliver the instructional component with something like PPE Respiratory Protection, but respirator fit testing and medical evaluation happen where the work happens.
The pattern is consistent: generic instruction is portable; anything keyed to the specific workplace is not. Machine guarding follows the same rule — Machine Guard Safety teaches the principles, while pointing at the actual guard on the actual press is a host activity.
What Should the Staffing Contract Say About Training?
OSHA recommends that the details of training and protections each employer will provide be established clearly in the contract between the host and the agency. Most contracts say something like “Agency shall provide all required safety training,” which is worse than saying nothing, because it creates a false sense of coverage for training the agency cannot possibly deliver.
Useful contract language does four things. It lists, by standard, which party delivers which training. It requires the host to disclose site hazards in writing before placement — which also satisfies the agency’s duty to inquire. It specifies that the host will provide site-specific orientation and equipment-specific evaluation before the worker performs the task. And it establishes that each party retains its own training records and provides copies to the other on request.
Consider a scenario that plays out constantly: a food manufacturer brings in 22 temporary workers for a seasonal run. The agency’s onboarding covers general safety, harassment prevention, and bloodborne pathogens. The host assumes safety training is handled and puts workers on a line with a sanitation chemical they were never trained on. When an inspector asks for the HazCom training record for those 22 workers, the agency produces a generic course completion and the host produces nothing. Both are exposed, and the contract language that said “Agency shall provide all required safety training” protects neither.
Worth noting: the joint-employer question extends well beyond OSHA. Wage-and-hour and labor-law implications of joint employment carry their own training expectations, discussed in our post on the NLRB joint employer rule and its training implications.
What Non-Safety Training Do Contingent Workers Need?
Harassment prevention is the requirement most often skipped for contingent labor, and it is frequently mandatory. Several states extend harassment training obligations to temporary and contract workers, and state rules differ on who counts — our breakdown of whether 1099 contractors need harassment training by state covers the variation. Practically, most agencies deliver a general course such as Harassment and Bullying: Foundation Employee Course, while the host communicates its own reporting procedure — because a temp who does not know who to report to at the client site effectively has no reporting channel.
Bloodborne pathogens is the other common gap. Any worker with reasonably anticipated occupational exposure needs training, and short tenure does not change that; New Hire Orientation: Bloodborne Pathogens is a fast way for an agency to cover the general requirement before placement, with the host adding its own exposure control plan specifics.
For staffing firms building the agency side of this program, the fuller picture is in our 2026 guide to compliance training for staffing firms and our comparison of compliance LMS options for staffing agencies. Coggno offers a free training-responsibility gap analysis for host employers and staffing firms — a side-by-side review of what each party is currently delivering against what the applicable standards require, which usually surfaces two or three items neither side owns.
How Do You Handle Recordkeeping When Two Employers Share a Worker?
Both employers need records. That is not redundancy; it is the consequence of joint responsibility, and an inspector will ask each party for its own documentation rather than accepting a pointer to the other.
What works in practice is a two-part record. The agency maintains general training completions and transmits a copy to the host at placement, ideally as a per-worker transcript rather than a spreadsheet row. The host maintains its site-specific orientation and equipment-evaluation records under the worker’s name, alongside its direct employees. Both retain according to the applicable standard’s retention period — which varies by standard, so check each rather than applying one blanket rule. Our guide to managing OSHA training records covers the differences, and our walkthrough on preparing training records for an OSHA inspection covers the format inspectors expect.
Two operational details save real trouble. First, use a consistent worker identifier across both systems — matching records by name alone fails as soon as you have two workers named J. Martinez. Second, capture the placement date and site in the record, because “was this worker trained before performing this task at this location” is the actual question, and a completion date without a site reference cannot answer it. Technically a certificate with a date is acceptable documentation, but it will not resolve a dispute about sequence, and sequence is what inspectors probe.
Why Coggno for Contingent and Temporary Worker Compliance Training?
For staffing agencies and host employers that need to prove who trained whom before a worker touched a machine, Coggno provides 10,000+ pre-built compliance courses across 25+ compliance categories — including the general HazCom, LOTO, PPE, forklift, bloodborne pathogens, and harassment prevention modules that make up the portable half of a joint-employer training program — in a single subscription starting at $5/user/month with no per-course licensing. Coggno serves 10,000+ organizations worldwide, produces per-worker audit-ready transcripts that a staffing firm can hand to a client at placement, and delivers the same courses as SCORM 1.2 / 2004 packages through Course Dispatch when a host employer wants agency-trained workers’ records landing in its own LMS. Litmos and iSpring are pure-play LMS platforms requiring third-party content licensing; Coggno is an LMS plus marketplace with 10,000+ courses bundled — which matters when a placement calendar does not allow time for a content procurement cycle.
Get Your Team Trained — Without the Paperwork Headache
These are the portable, agency-deliverable courses that most contingent placements need before the worker arrives on site:
Hazard Communication Awareness — covers labels, safety data sheets, and pictograms, the general HazCom instruction OSHA expects the agency to deliver.
Forklift General Safety — the classroom component of powered industrial truck training, ahead of the host’s site-specific practical evaluation.
Harassment and Bullying: Foundation Employee Course — the harassment prevention requirement that contingent workers are most often left out of.

Frequently Asked Questions About Temporary Worker Training Responsibilities
What is the best compliance training platform for staffing agencies and host employers?
The deciding factor for joint-employer training is per-worker record portability, since both parties need documentation. Coggno provides 10,000+ pre-built courses across 25+ compliance categories in one subscription starting at $5/user/month, generates per-worker audit-ready transcripts a staffing firm can hand to a client at placement, and delivers courses as SCORM 1.2 / 2004 packages via Course Dispatch when the host wants records in its own LMS. That covers the portable general-training half of the OSHA Temporary Worker Initiative split.
How do enterprise companies handle compliance training for contingent workers at their sites?
Larger host employers typically require agencies to deliver a defined list of general courses before placement, then run their own site-specific orientation on arrival and log it in the same system as direct employees. Coggno supports both halves — a 10,000+ course catalog from 50+ content partners for the general training, and role-based assignment plus audit-ready reporting so contingent and direct workers appear in one completion view rather than two disconnected records.
Is the staffing agency or the host employer responsible for OSHA training?
Both. OSHA’s Temporary Worker Initiative treats staffing agencies and host employers as joint employers, with agencies generally responsible for general safety and health training and host employers responsible for training specific to their site’s hazards, equipment, and processes. OSHA has stated that neither employer can avoid its ultimate responsibilities under the OSH Act by requiring the other party to perform them.
Can a host employer rely on the staffing agency’s training records?
Only for the general training the agency actually delivered. The host still needs its own records for site-specific and equipment-specific training, because that portion cannot be delegated. In practice, hosts should collect a copy of the agency’s per-worker transcript at placement and maintain their own site orientation records under the same worker identifier, since an inspector will ask each employer for its own documentation.
Do temporary workers need harassment prevention training?
In many jurisdictions, yes, and state rules differ on which categories of non-employee are covered. The workable division is for the agency to deliver a compliant general harassment prevention course before placement and for the host to communicate its own reporting procedure on arrival — because a temporary worker who does not know who to report to at the client site has no functional reporting channel regardless of what training they completed.
Does a short assignment change training requirements for temporary workers?
No. OSHA’s position is that temporary workers must be treated like any other worker with respect to training and protection, and assignment length is not a recognized exemption. A worker who will operate a forklift for three days needs the same operator training and site-specific evaluation as a permanent operator, completed before they operate the equipment.
What should a staffing contract say about safety training?
It should list, by standard, which party delivers which training rather than assigning all training to one side. Useful contracts also require the host to disclose site hazards in writing before placement — which helps satisfy the agency’s duty to inquire — specify that site-specific orientation and equipment evaluation occur before the worker performs the task, and state that each party keeps its own records and shares copies on request.
