Occupational Safety Companies in Bursa: A Guide to Choosing an OSGB

Who are you looking for when you search for an “occupational safety company” in Bursa?

Most employers who search for “occupational safety companies in Bursa” or “OSGB Bursa” start from the same need: to appoint the OHS specialist and workplace physician their workplace is legally required to have. In the search results, however, organisations doing very different jobs appear side by side. Some appoint specialists and physicians, some only carry out equipment inspections or workplace environment measurements, and some sell protective equipment. Collecting quotes without making this distinction means ending up with offers that cannot be compared with one another.

Turkish legislation has no definition of an “occupational safety company”. Law No. 6331 on Occupational Health and Safety calls the organisation from which specialist and physician services can be obtained externally a joint health and safety unit (OSGB); the details are set out in the Regulation on Occupational Health and Safety Services. In short, an “occupational safety company” that will appoint a specialist and a physician to your workplace must be an OSGB holding an authorisation certificate from the Ministry of Labour and Social Security.

This guide focuses on the first row, i.e. choosing an OSGB; the work in the other rows is planned and followed up by the OSGB.

What do occupational safety companies in Bursa do? The legal framework

Article 6 of the Law requires every employer to appoint an OHS specialist and a workplace physician; in very hazardous workplaces with 10 or more employees, other health personnel (DSP) must also be appointed. When you sign a contract with an OSGB, these people are assigned to your workplace through İSG-KATİP (the Ministry’s OHS registration system) and carry out the following:

• Risk assessment (Art. 10): identifying hazards and planning measures; under the regulation, renewal at least every 2 years in very hazardous, 4 years in hazardous and 6 years in less hazardous workplaces, and whenever changes occur.
• Emergency plan and drills (Art. 11): designating the teams, preparing the plan, at least one drill a year.
• Training (Art. 17): induction, basic OHS and refresher training.
• Health surveillance (Art. 15): pre-employment and periodic medical examinations, with the tests determined by the physician.
• Written findings and recommendations: notifying the employer in writing of deficiencies seen on site and following them up.
• Coordination: planning workplace environment measurements and work equipment inspections with authorised persons and organisations.

For details of the services, see our OHS specialist services, workplace physician services and workplace nursing (DSP) pages. The legal definition, staffing requirements and supervision of an OSGB are explained in our article What is an OSGB?.

Let us make one point clear from the outset: under Article 4 of the Law, obtaining services externally does not remove the employer’s responsibility, and the cost of OHS cannot be passed on to employees. The OSGB identifies, recommends and follows up; taking the measure is the employer’s decision.

An OSGB, or an in-house specialist and physician?

The Law does not require the service to be obtained in only one way. For an employer in Bursa, the options are:

• In-house specialist and physician: You employ people holding the required certificates. As the number of employees grows, full-time appointment becomes mandatory: for the specialist, one full-time person for every 500 employees in hazardous, every 250 in very hazardous and every 1,000 in less hazardous workplaces; for the physician, these thresholds are 1,000, 750 and 2,000. For workplaces approaching these thresholds, it makes sense to compare in-house employment with external services in terms of cost and continuity.
• OSGB: The specialist, the physician and, where required, DSP are appointed under a single contract. If an appointee leaves, a replacement must be assigned within 30 days. This is a practical route for businesses below the full-time thresholds, because employing certified staff for a few hours a month is often not feasible.
• The employer themselves: An employer holding a specialist or physician certificate may take on the service themselves, subject to conditions depending on the hazard class and number of employees. In less hazardous workplaces with fewer than 50 employees, the employer or their representative may carry out the service after completing the training prescribed by the Ministry; pre-employment and periodic medical examinations are excluded, and an undertaking is filed on İSG-KATİP.
• ÇASMER: With the amendment introduced by Law No. 7538, the service can also be obtained from an Employee Health Centre (ÇASMER).

How do you verify the authorisation of an OSGB in Bursa?

Before comparing quotes, make sure the organisation submitting the quote really is an authorised OSGB. In five steps:

1. Ask for a copy of the authorisation certificate. Note the trade name, address and date of issue. The certificate must be renewed (endorsed) every 5 years, counted from the date it was first issued. An OSGB that fails to renew on time has its existing contracts cancelled and cannot sign new ones; if the renewal date is close, ask about the status in writing.
2. Check against the official list. Download the “List of Authorised OSGBs and TSMBs” published on the İSG-KATİP home page and search for the organisation by its trade name. The trade name on the quote, the contract and the list must be identical.
3. Check the service area. The address on the certificate must be in Bursa or in a province bordering Bursa (details below).
4. Ask for the names of the people to be appointed. The specialist’s certificate class must match your hazard class: class A for very hazardous, at least class B for hazardous and at least class C for less hazardous workplaces (Law, Art. 8/5).
5. Approve the contract on İSG-KATİP. The contract is prepared in line with the template in the system and approved by both parties within 5 days at the latest; work cannot begin under an unapproved appointment. On the approval screen, check the trade name, the appointees and the monthly service times. For a screen-by-screen walkthrough, see our article on İSG-KATİP contract approval.

12 criteria for comparing occupational safety companies in Bursa

For the comparison to be meaningful, give every OSGB the same information: the NACE code and hazard class in your SGK registration, the number of employees, the shift pattern, the workplace address and the OSB (organised industrial zone) it is in, if any, and the number of workplaces. Then assess the quotes with this table:

The first five criteria concern legal compliance and are not negotiable. The remaining seven show whether the service will actually work on site. For a detailed explanation of each criterion and additional questions by sector, see our article on what to look for when choosing an OSGB. To compare quotes on price, our OSGB prices in Bursa page explains the minutes and cost items one by one.

Red flags: stop at these offers

If you hear any of the following, question the offer again:

• “We’ll sort out the İSG-KATİP approval later.” Work cannot begin under an unapproved appointment; for that whole period, your workplace also has no appointees on record.
• The quote does not state monthly minutes, or the minutes stated are below the minimum resulting from your number of employees and hazard class.
• “We’ll also carry out and report the periodic inspections ourselves.” Under Art. 14/A-3 of the Regulation on Work Equipment, authorised OSGBs and their employees may not provide periodic inspection services; inspections are carried out by authorised persons registered in EKİPNET or by accredited inspection bodies. The OSGB’s role is to plan and follow up periodic inspections.
• The specialist’s name and class will be notified “after the contract”.
• “We don’t need to come; we’ll fill in the logbook.” A service without site visits exists only on paper.
• The name and proficiency certificate of the laboratory that will carry out the measurements are unclear. A measurement result from an uncertified laboratory is invalid.
• You are told that all training will be delivered remotely. Induction training is face to face and hands-on in every hazard class.
• The authorisation certificate is not shown, or the address on it is outside Bursa and its neighbouring provinces.

Planning specific to Bursa: OSBs, districts and sectors

According to the January 2026 list of the Bursa Chamber of Commerce and Industry (BTSO), the province has 17 active organised industrial zones (OSBs). The zone your workplace is in directly affects the visit pattern and travel planning:

• Nilüfer: Bursa OSB, Nilüfer OSB, Hasanağa OSB and Kayapa OSB; in Badırga, the Bursa Leather Specialised and Mixed OSB and TOSAB. Details: Nilüfer OSB.
• Osmangazi, Gürsu and Kestel: Demirtaş OSB, Uludağ OSB, Kestel OSB and Barakfakih OSB. Details: Kestel.
• İnegöl: İnegöl OSB, İnegöl Furniture and Woodworking Specialised OSB and Yenice OSB. Details: İnegöl.
• Karacabey, Mustafakemalpaşa and Yenişehir: TEKNOSAB, Mustafa Kemalpaşa OSB, Mustafa Kemalpaşa–Mermerciler OSB and Yenişehir OSB.
• Industrial and service areas outside the OSBs: workshops in Yıldırım, the free zone and ports in Gemlik, and businesses in Mudanya, Orhangazi and İznik.

The regulations state explicitly that travel time between workplaces does not count as service time. For a workplace in an OSB far from the centre, ask the OSGB about visit days and how the night shift will be covered.

The hazard class is determined by the main activity in your SGK registration; where there is more than one main activity, the higher class applies. Because the Annex 1 list was renewed with NACE Rev.2.1 on 13 March 2025, a quote prepared on the basis of old codes may rest on the wrong class. Examples from Bursa’s leading sectors:

Hardwood dust is a further concern in İnegöl’s furniture businesses: it is listed among carcinogenic processes, and its occupational exposure limit value is 5 mg/m³.

The service area rule: Bursa and 6 neighbouring provinces

Under Art. 12/5 of the Regulation on Occupational Health and Safety Services, an OSGB may only provide services in the province where it is located and in the provinces bordering it. What counts is the address on the authorisation certificate. The service area of an OSGB in Bursa is therefore limited to seven provinces: Bursa, Yalova, Kocaeli, Sakarya, Bilecik, Kütahya and Balıkesir.

The practical consequences are:

• A business headquartered in Bursa with a branch in, for example, Kocaeli or Balıkesir can work with the same OSGB for both workplaces.
• For your branches in Istanbul, İzmir or Ankara, you need an OSGB authorised in that province or in a province bordering it.
• If the authorisation certificate of an organisation quoting for your workplace in Bursa was issued for an address outside these seven provinces, do not sign a contract.

Frequently Asked Questions

Which is the best OSGB in Bursa?

There is no official “best OSGB” ranking; the right OSGB depends on your workplace’s hazard class, number of employees and location. The objective criteria are: a valid authorisation certificate and renewal, an address in Bursa or a neighbouring province, a specialist of the class appropriate to your hazard class, monthly minutes written into the contract that meet the minimum, a written work plan and regular reporting. Among the quotes that meet these criteria, choose the one whose scope is set out most clearly.

What do occupational safety companies in Bursa do?

Occupational safety companies in Bursa, known in the legislation as OSGBs (joint health and safety units), appoint OHS specialists, workplace physicians and, where necessary, other health personnel to workplaces. This team runs the risk assessment, emergency plan, OHS training and health surveillance, and plans workplace environment measurements and periodic inspections of work equipment with authorised persons and organisations. Taking the measures remains the employer’s responsibility.

Is working with an OSGB mandatory?

What is mandatory is appointing an OHS specialist and a workplace physician; an OSGB is one way of doing so. The employer may employ certified specialists and physicians in-house or, if they hold a certificate, take on the service themselves; in less hazardous workplaces with fewer than 50 employees, the employer or their representative may also carry out the service after completing the Ministry’s training. An employer who does not use these options obtains the service from a Ministry-authorised OSGB.

Where can I find the list of authorised OSGBs in Bursa?

The “List of Authorised OSGBs and TSMBs” is published on the home page of İSG-KATİP (isgkatip.csgb.gov.tr), the system of the Ministry of Labour and Social Security. Search this list for the organisation you received a quote from by its trade name and compare it with the copy of the authorisation certificate you hold. Company directories and listing sites do not show authorisation status; this list is the official source.

How can I tell whether an OSGB’s authorisation certificate is valid?

Ask for a copy of the authorisation certificate and check the trade name, address and date of issue; the certificate must be renewed every 5 years, counted from the date it was first issued. Then search for the organisation in the list of authorised OSGBs on İSG-KATİP. Because an OSGB that fails to renew on time has its existing contracts cancelled, ask about the status in writing if the renewal date is close.

Can an OSGB from outside Bursa serve my workplace in Bursa?

Only an OSGB whose authorisation certificate address is in a province bordering Bursa, namely Yalova, Kocaeli, Sakarya, Bilecik, Kütahya or Balıkesir, can provide the service. Art. 12/5 of the Regulation on Occupational Health and Safety Services limits an OSGB’s service area to the province where it is located and the provinces bordering it. For example, as Istanbul does not border Bursa, an OSGB registered at an Istanbul address cannot serve a workplace in Bursa.

Can an OSGB carry out periodic inspections?

No. Under Art. 14/A-3 of the Regulation on Health and Safety Requirements for the Use of Work Equipment, authorised OSGBs and their employees may not provide periodic inspection services. Inspections are carried out by engineers, technical teachers, technicians or senior technicians registered in EKİPNET and, for the equipment that requires it, by accredited inspection bodies; the OSGB takes on the planning and follow-up of these inspections.

What should I do if I want to change my current OSGB?

Plan the dates so that your workplace is not left without appointees for even a single day: the new contract is approved on İSG-KATİP by both parties within 5 days at the latest, while termination of the old contract is notified within 5 working days. The previous OSGB is obliged to hand over the records when the contract ends; take delivery of the risk assessment, training records and health files with a signed handover report. For a step-by-step transition, see our guide to changing your OSGB.

How much do OSGB services cost in Bursa?

There is no single price; what really determines the fee is the legally required monthly physician and specialist time resulting from your number of employees and hazard class. For example, in a workplace with 50 employees, this time is 12 hours 30 minutes a month in a less hazardous workplace and 58 hours 20 minutes, including DSP, in a very hazardous one. Training, medical tests, travel and the shift pattern are also reflected in the quote; the items that make up the fee are explained in our article on OSGB prices, and example time tables for Bursa are on our OSGB prices in Bursa page.

What information should I prepare to get a quote from an OSGB?

The company’s trade name, the workplace address and the OSB it is in, if any, the NACE code and hazard class in the SGK registration, the number of employees, the shift pattern and the number of workplaces are sufficient. Apprentices and interns are not included in the time calculation, so state them separately. Sharing the status of your existing risk assessment, emergency plan and training records allows the quote to be prepared more accurately.
