A population statistically more exposed to workplace accidents
The figures are clear. According to the Carsat Hauts-de-France, the number of accidents among temporary workers is twice as high as the national average, and 1.8 times more severe. This gap is not explained by the nature of the work itself, but by the conditions under which it is performed: encountering a new environment, the need to quickly adapt to instructions that may vary from one site to another, and short-term assignments that leave little time for full integration.
TheINRS confirms this : the first few weeks on the job expose any new arrival (employee, apprentice, temporary worker, or intern) to a higher risk of workplace accidents. Onboarding processes within the company and at the specific workstation are therefore a critical issue, which should be prepared for as early as initial training, with a mentor to ensure proper integration.
A nuance is worth noting, however: a field report from the INRS (Travail & Sécurité, June 2023) features the testimony of an industrial facility manager who observed that accidents rarely occur at the very beginning of an assignment, but rather after the first month—at the point when the temporary worker has gained confidence and lets their guard down. This observation, specific to that site, serves as a reminder that an effective prevention strategy must not be limited to the first day: it must be maintained throughout the entire duration of the assignment.
Who is responsible for a temporary worker's safety ?
This is the most frequently asked question, and the answer is clear: responsibility is shared, with clearly defined roles.
The role of the temporary employment agency (TEA)
The temporary employment agency must verify that the temporary worker has the necessary training and qualifications for the position specified in the assignment contract: operating machinery, electrical work, working at heights, etc. It also ensures the general safety training for their employee.
The role of the host company (HC)
The host company bears the majority of the practical obligations once the temporary worker is on-site. According to the INRS, the host company must, in particular, provide practical and appropriate safety training upon arrival, tailored to the actual position held, and complete information prior to the work accident report (Cerfa no. 60-3741) in the event of an incident.
A significant financial change has been in effect since July 2024: the cost of workplace accidents involving temporary workers is now shared equally between the host company and the temporary employment agency, with a clearly stated goal: to encourage companies that use temporary labor to invest more in prevention.
The 3 mandatory training sessions upon a temporary worker's arrival
The Labor Code requires three distinct types of training, divided between the two companies, as detailed by Prévention BTP.
General safety training
Provided by the temporary employment agency, this covers basic prevention principles, regardless of the specific position to be held.
On-the-job training
Provided by the host company upon arrival on site, this practical and appropriate training must be tailored to the actual position held and the specific risks of the work environment: articles L.4141-1 and L.4141-2 of the Labor Code.
Enhanced training for high-risk positions
This is the most legally sensitive point. Article L.4154-2 of the Labor Code stipulates that temporary workers assigned to positions presenting specific risks to their health or safety must receive enhanced safety training, as well as appropriate induction and information. A major point of vigilance: in the event of an accident in this type of position where enhanced training was not provided, the law presumes inexcusable fault on the part of the employer. An aggravated liability regime, confirmed by the case law of the Court of Cassation, as reported by Centre Inffo.
The legal framework you need to know
Several articles of the Labor Code define these obligations:
- Articles L.4141-1 and L.4141-2 : employer safety training requirements for all employees, including temporary staff
- Article L.4154-2 and following : enhanced safety training for high-risk positions, and presumption of inexcusable fault in the event of non-compliance
- Articles L.1251-21 to L.1251-23 : responsibilities of the user company and provision of personal protective equipment (PPE)
- Articles D.4154-1 to D.4154-6 : list of tasks prohibited for temporary employees
- Article L.1251-22 : mandatory pre-assignment medical fitness examination for high-risk positions, even for short-term assignments
Temporary work and prevention plans: a direct link that should not be overlooked
An often-overlooked point: when a temporary worker is assigned to a project where multiple companies are working on the same site (construction sites, maintenance work, subcontracting), the obligations related to the prevention plan are in addition to those specific to temporary employment. The co-activity generated by the simultaneous presence of several companies on a site requires formalized coordination, regardless of the status (temporary worker, subcontractor, service provider) of the individuals present.

Risks for companies that fail to meet these obligations
The consequences go far beyond a simple warning:
- Presumption of inexcusable fault in the event of an accident in a high-risk position without the required enhanced training
- Criminal liability for the company and its executives in the event of a serious breach of safety obligations
- Direct financial burden since July 2024, with the cost of workplace accidents shared equally between the user company and the temporary employment agency
- Risk of audits and formal notices from the labor inspectorate, following the same logic as other safety obligations that have already been strengthened in recent years
Structuring a prevention approach for your temporary staff
A few concrete actions to implement from the moment they arrive:
- Formalize a dedicated onboarding process, with a mentor identified from day one
- Identify high-risk roles in advance that may be filled by a temporary worker, to automatically trigger enhanced training
- Verify qualifications and certifications provided by the temporary employment agency before the start of the assignment
- Maintain vigilance throughout the entire assignment, not just during onboarding: the drop in attention observed in the field after the first month confirms this
- Coordinate the prevention plan if multiple companies are operating on the same site
How can QHSE software secure the onboarding of your temporary staff ?
Tracking qualifications provided by the temp agency, automatically triggering enhanced training for high-risk roles, documenting safety inductions, and coordinating prevention plans with external contractors on-site is a heavy administrative burden, especially during peak seasons. The Symalean prevention plan management module centralizes all these documents (prevention plans, work permits, safety protocols) with integrated electronic signatures to obtain validation from all partner companies.
FAQ
Who is responsible for a temp worker's safety: the temp agency or the host company ?
Both, with complementary roles. The temp agency verifies qualifications and provides general training; the host company provides job-specific training and, if necessary, enhanced safety training.
Does a temp worker on a two-day assignment need to receive safety training ?
Yes. The duration of the assignment does not exempt the employer from any mandatory training required by the Labor Code, even for the shortest assignments.
What is considered a high-risk role for a temp worker ?
A role involving specific health or safety risks that requires enhanced training and a tailored induction under Article L.4154-2 of the Labor Code, as well as a prior medical fitness examination.
Is the cost of a workplace accident involving a temp worker charged to the host company ?
As of July 2024, this cost is shared equally between the host company and the temp agency, whereas it was previously allocated differently.
