DOSAB OSGB: OHS services for textile and automotive plants in Demirtaş OSB
Demirtaş Organised Industrial Zone (DOSAB) is in Osmangazi, the district next to our head office in Nilüfer. In this zone, dominated by textiles and automotive, we provide workplace physician and occupational safety services planned around shift production and the different risks of the two sectors.

How do we deliver OHS services for plants in DOSAB?
Our DOSAB OSGB service covers an industrial zone in Osmangazi, the district next to our head office in Nilüfer. According to DOSAB’s own data, the zone was established as an OSB in 1990 and acquired legal personality on 6 April 2001 under Law No. 4562; across its 491 hectares, 70 per cent of companies operate in textiles and 20 per cent in automotive. The zone’s industrial history goes back to the car factory opened in 1971.
The OHS agendas of the two sectors differ markedly:
| Topic | Textile plants | Automotive suppliers |
|---|---|---|
| Class example (2025 Annex 1) | Cotton weaving 13.20.16 and bleaching and dyeing 13.30.01: hazardous | Motor vehicle parts and accessories 29.32.20: hazardous |
| Key risks | Noise, fibre dust, dyehouse chemicals, steam and hot surfaces | Presses, welding, assembly line ergonomics, forklifts |
| Health surveillance | Hearing tests if 85 dB(A) is exceeded, monitoring of respiratory complaints | Hearing, musculoskeletal complaints, welding fumes |
Note that bleaching and dyeing was very hazardous in the 2012 list and is hazardous in the 2025 list. Files set up under the old class may need their time, training and examination calculations updated. If weaving, dyeing and garment making are all carried out as main activities at the same workplace, the higher class applies.
DOSAB has shared logistics areas such as a lorry park, a bonded warehouse and a fuel station; heavy dispatch traffic also spills over into factory yards. We organise our visits as follows:
- We spread physician and specialist visits across different shifts and include night-shift teams in site tours.
- For dyehouse and finishing departments, we draw up a chemical inventory and plan workplace environment measurements with authorised laboratories.
- For suppliers subject to audits by vehicle manufacturers, we keep records ready according to the audit calendar.
Areas we take into account in DOSAB
- Textile production plantsWeaving, knitting, dyeing and finishing; noise, chemicals and steam
- Automotive supply plantsMetalworking, presses, welding and assembly lines
- Lorry park, bonded warehouse and fuel stationThe OSB’s shared logistics areas; vehicle and pedestrian traffic
- Wastewater treatment and SCADA infrastructureShared infrastructure services operated by the OSB
What we pay attention to in this area
Noise in weaving halls
We plan noise measurement with an authorised laboratory, and monitor that hearing protection is available above 80 dB(A), worn above 85 dB(A), and that hearing tests are carried out.
Dyehouse chemicals
For the storage, transfer and mixing of dyes, auxiliary chemicals and alkalis, we add eyewash stations, chemical-resistant PPE and spill response kits to our checklist.
Shift handover
Passing on machine status and fault information at shift handover affects accident risk. We check the handover notes and lockout-tagout practice during maintenance on our site tours.
Adapting to class changes
For activities whose hazard class changed with the 2025 Annex 1, we recalculate training refresher intervals, examination frequency and monthly service times according to the new class.

OSGB services in Demirtaş OSB: frequently asked questions
Is our textile dyehouse no longer in the very hazardous class?
Textile bleaching and dyeing under code 13.30.01 is in the hazardous class in the Annex 1 list renewed on 13 March 2025; in the 2012 list it was very hazardous. Your class is determined by your NACE code in İSG-KATİP (the Ministry’s OHS registration system). In the hazardous class, DSP is not mandatory; basic OHS training is at least 12 hours, refresher training is every 2 years, and periodic medical examinations take place at least every 3 years.
How should we plan the number of first aiders for the night shift?
In the hazardous class, 1 first aider is required for every 15 employees. Rather than concentrating the total in one shift, we recommend distributing them so that every shift has enough first aiders. For example, if 60 people work on the night shift, the aim is to have at least 4 first aiders on that shift. A first aid certificate is valid for 3 years; refresher training is taken within the 3 months before expiry.
As an automotive supplier, what do you look at on press and welding lines?
The first things we look at are the annual periodic inspection of presses and press brakes (arranged through our solution partners), whether guards such as two-hand controls and light curtains work, lockout-tagout during die changes, and ventilation for welding fumes. If you carry out laser cutting, we assess together that this activity (25.53.03) is in the very hazardous class and would raise your workplace’s class if it is one of your main activities.
Who responds first in an emergency in DOSAB?
The first response is made by the workplace’s first aiders, the firefighting team and the 112 emergency line. That is why our planning focuses on the training, equipment and drills of the teams at your site. After an accident, we carry out the incident investigation, remind you of the notification to the Social Security Institution (SGK) due within 3 working days and review the risk assessment. We also recommend adding DOSAB management’s electricity and natural gas lines to the contact list in your emergency plan.
What do you check in our warehouse and dispatch area?
We track the annual periodic inspection of forklifts and pallet trucks, industrial racking and doors, which is carried out through our solution partners. On racking we check load capacity labels, impact damage and anchoring; on site we check the separation of pedestrian and vehicle routes, fall prevention at loading ramps and the rules for lorry drivers moving within the site. We also keep forklift operators’ certificates on file.
