KOSAB OSGB: OHS services for textile and metal businesses in Kestel OSB
Kestel Organised Industrial Zone (KOSAB) is a compact, textile-focused industrial zone on the eastern edge of Bursa city centre. We provide services with a visit and documentation routine that takes seasonally changing headcounts and shift production into account.

How do we deliver OHS services to businesses in KOSAB?
Two features of the zone shape our KOSAB OSGB service: the weight of textiles and the seasonal variability of headcount. According to KOSAB’s data, of the 78 active workplaces in the zone, 56 are in textiles, 12 in metal, 3 in food, 2 in plastics and 1 in furniture. The OSB states that employment is about 5,000 people and varies seasonally. Originally operating as the Kestel Municipality Industrial Area, the zone received its OSB registration certificate on 7 May 2004; with 73.43 hectares and 95 plots, it is one of Bursa’s compact OSBs.
When headcount changes, OHS obligations change too. That is why we monitor the number not only at the start of the contract but throughout the year:
| Item that changes | Rule |
|---|---|
| Monthly physician and specialist time | Recalculated on a minutes-per-employee basis |
| Number of first aiders | 1 per 15 employees in hazardous, 1 per 10 in very hazardous |
| Support staff | At least 1 person per team for up to 40 employees in hazardous, 30 in very hazardous |
| DSP | Required in the very hazardous class with 10 or more employees |
| New employees | Pre-employment medical examination and induction training |
In textile businesses, noise, fibre dust and rotating parts stand out in weaving and knitting halls; in plants that carry out dyeing, chemicals, hot water and steam are the main risks. In metal businesses, presses, welding and grinding form a separate topic. For small and medium-sized plants, we keep the file structure simple and prepare an annual OHS calendar that the employer can also follow.
We schedule our visits on the same days as other businesses in Kestel and Gürsu and combine physician and specialist visits where possible. In between, we compare the appointment time in İSG-KATİP (the Ministry’s OHS registration system) with the current headcount, and update the examination and training calendar with you before seasonal hiring periods.

What we pay attention to in this area
Tracking a variable workforce
When the workforce grows with orders, we recalculate first aiders, support staff and monthly service times, and add any understaffed teams to the training plan.
Weaving and knitting halls
We select hearing protection based on measurement results, list employees who need hearing tests and plan for measurements to be repeated when new machines are added to the hall.
Evacuation on compact plots
In a zone where plots sit side by side in a limited area, we verify the evacuation plan drawing on site so that stock does not narrow escape routes and the assembly point does not clash with neighbouring plants.
Garment making and dyeing under one roof
Outerwear garment making (14.21.01) is less hazardous. If the same workplace also carries out a higher-class main activity such as weaving or dyeing, we check that the higher class is applied.

OSGB services in Kestel OSB: frequently asked questions
Our headcount varies between 40 and 70 during the year; how are appointments handled?
Monthly service times depend on headcount; when the number changes permanently, the appointment time in İSG-KATİP needs to be updated. In the hazardous class, for 70 employees the specialist time is at least 1,400 minutes and the physician time 700 minutes per month; with 40 employees these drop to 800 and 400 minutes. We review the number with you periodically and make the update on time.
Do seasonal workers also need a pre-employment medical examination?
Yes. The examination takes place on recruitment; if your work is in the hazardous or very hazardous class, an employee cannot be put into production until the physician has issued a fitness-for-work report. A short period of employment does not change this rule. Reports are, as a rule, obtained from the workplace physician; in busy periods we group examinations and schedule them by start date. Records are kept on the Annex 2 form and health information is kept confidential.
Our garment workshop is less hazardous; do we still need a physician and a specialist?
Yes. With the Constitutional Court decision published in the Official Gazette on 9 December 2025, the postponement for less hazardous workplaces with fewer than 50 employees was annulled; these workplaces are also covered by the obligations. In the less hazardous class, basic OHS training is at least 8 teaching hours, refresher training is given every 3 years and periodic medical examinations take place at least every 5 years.
What should our emergency plan include for a fire on the neighbouring plot?
Your plan should cover not only your own building but also the possibility of a fire at a neighbouring plant reaching you; a new external hazard is one of the situations that require the risk assessment to be renewed. We recommend agreeing assembly areas and communication channels with neighbouring plants and adding 112 and the OSB management’s lines to your contact list.
We take interns through school–industry cooperation; what should we do from an OHS perspective?
The 2026 training regulation extends induction training to apprentices and interns; an intern receives this training face to face before going on site. For young workers, the periodic medical examination interval is at most 6 months. Apprentices and interns are not counted when calculating physician and specialist time; however, we recommend separately identifying in the risk assessment the jobs unsuitable for young workers and assigning an experienced supervisor to each intern.
