Kocaeli OSGB: planned OHS services from Bursa for workplaces in an industrial province
Kocaeli shares a border with Bursa and is therefore within our area of authorisation. We see our service as a good fit especially for companies with sites in both provinces, those tied to the supply chain in Bursa, and those on the southern shore of the gulf.

How do we serve your workplace in Kocaeli from Bursa?
Employers choosing a Kocaeli OSGB (joint health and safety unit) have many local options. This page sets out plainly when a Bursa-based OSGB can be the right choice. The legal basis is clear: the regulations on OHS services define an OSGB’s area of authorisation as the province where it is established plus the provinces bordering it, and Kocaeli is one of Bursa’s neighbours within this scope.
The Governorship of Kocaeli notes that the province’s leading industries are automotive manufacturing and its supply industry, machinery manufacturing, iron and steel, chemicals, plastics and rubber, electrical machinery and metal products. According to 2024 data cited by the Governorship, 44 per cent of Türkiye’s vehicle production comes from Kocaeli. The OSBÜK list includes organised industrial zones (OSBs) such as Gebze, Gebze Dilovası, TOSB Automotive Supply Industry Specialised OSB, Gebze V (Chemicals) Specialised OSB, Gebze VI (İMES) Machinery Specialised OSB, Gebze Plastikçiler, Asım Kibar, Arslanbey and Kandıra Food Specialised OSB.
Our service is particularly suited to:
- Companies with sites in both Bursa and Kocaeli that want to work the same way in both provinces,
- Businesses supplying parts to the automotive supply chain in Bursa that want a consistent file structure for customer audits,
- Workplaces on the southern shore of the gulf, in districts close to Yalova and Bursa.
Kocaeli is reached from Bursa via the motorway and the Osmangazi Bridge; we set visit times taking into account both the traffic on this route and your shift start times. A separate contract and assignment is made in İSG-KATİP (the Ministry’s OHS registration system) for each workplace. We tie visits to pre-agreed days and combine physician and specialist visits on the same day wherever possible. Between visits, training records, examination dates and the periodic inspection schedule are monitored remotely. The minimum monthly times do not decrease with distance; a site in Kocaeli receives the same service time as an equivalent site in Bursa.

One method in two provinces
We keep the risk assessment format, training records and examination tracking in the same structure at your sites in Bursa and Kocaeli, so the two workplaces can be compared during customer audits.
Neighbour risk in chemical zones
In areas with many chemical and plastics plants, we add fire and spread scenarios that could originate from a neighbouring plant to the risk assessment as external hazards.
Automotive customer audits
We keep the training, medical examination, periodic inspection and near-miss records requested in OEM supplier audits ready for audit.
Shifts and visit days
At three-shift sites we schedule visits close to shift handover and track training and examinations for night-shift employees separately.

Frequently asked questions about OSGB services in Kocaeli
With so many OSGBs in Kocaeli, why should I work with one in Bursa?
For many businesses a local OSGB in Kocaeli is the natural choice. A Bursa-based service makes sense for companies with sites in both provinces, those tied to customers or a supply chain in Bursa, or those located in districts close to Yalova and Bursa. We recommend deciding after discussing the visit schedule and how you will reach your specialist with us before the quotation.
Can we have a single contract for our two factories in Bursa and Kocaeli?
In İSG-KATİP, contracts and assignments are made per workplace; a separate record is opened for each workplace. Commercially, we can manage both workplaces under the same quotation and the same service plan. However, the risk assessment, emergency plan and assignment time of each workplace are prepared separately according to its own hazard class and number of employees.
Do we need other health personnel (DSP) at our metal plating plant in Kocaeli?
Nickel plating of metals (25.51.01) is in the very hazardous class in the Annex-1 list renewed in 2025. In very hazardous workplaces with 10 or more employees, other health personnel are assigned in addition to the specialist and the physician; if there is a full-time physician, a DSP is not required. You can check your class and required times with the obligation calculator.
How do we switch OSGB for our workplace in Kocaeli?
Termination of the current contract is notified in İSG-KATİP within 5 working days. The new contract is prepared in line with the template in the system and both parties approve it within 5 days at the latest. To avoid any gap during the transition, we time the approval of the new assignment to the end of the old contract, take over the existing risk assessment, training and examination records, and list any gaps at the first visit.
If we introduce a new chemical or production line, is the risk assessment renewed?
Yes. A risk assessment is renewed at least every 2 years in very hazardous, 4 years in hazardous and 6 years in less hazardous workplaces; however, changes in technology, substances or equipment, a change in production method, changes in limit value legislation and measurement or health surveillance results require renewal without waiting for this period. We review the safety data sheet of the new chemical and identify the employees who will be exposed and the training they need.
