Workplace Safety for Outsourced Staff: Who's Actually Liable

Why this question slips through the cracks

When staff are employed by a staffing agency but physically work at the client's site, it's tempting to assume safety is purely the agency's job, since it's the formal employer on paper. In practice that's a dangerous shortcut: working conditions, equipment, and the specific risks of a given site are controlled by whoever owns that site — not by the agency that merely assigned people to it.

How responsibility actually splits

The general rule: the agency is responsible for what falls on it as the employer — a pre-deployment medical check, a general safety briefing, personal protective equipment. The client is responsible for safety on its own site specifically — equipment condition, task-specific briefing, and working conditions that match the site's actual profile. Neither side can fully offload this to the other.

What the contract needs to spell out

A staffing or outsourcing agreement should clearly state who runs the induction briefing, who signs off on a worker being cleared to start, and who supplies protective equipment — the agency as part of the service, or the client as the site owner. Without this clause, an incident turns into a back-and-forth about who was supposed to do what, instead of a response to the incident itself.

Briefing and sign-off before work starts

Standard practice is for the agency to run a general safety briefing before the crew is deployed, and for the client to run a task-specific briefing covering the particular site or equipment right before work begins. Two layers of briefing cover both the general and the site-specific risks, which is exactly why staffing contracts usually spell this out as its own clause rather than folding it into general terms.

What happens if an incident occurs

If an incident involves an outsourced worker, liability comes down to whose specific duty was breached — a missing briefing on the agency's side, or unsafe conditions on the client's side. A clearly written split of duties in the contract directly determines how quickly and unambiguously the cause and the responsible party can be identified.

How to check a contractor is actually ready

Before signing, ask the agency exactly how briefing and medical checks are organized, rather than accepting a generic "it's all compliant." Staff outsourcing from ASHA Ukraine includes a mandatory briefing before deployment, and for construction sites, construction staff outsourcing additionally accounts for the specifics of each project stage.
