BOZP for manufacturing and industry — categorisation of work, measurements and certifications

Categorisation of work is the process by which every job is classified into one of four categories according to the degree of health risk. It is governed by § 31 of Act No. 355/2007 Coll. and Decree of the Ministry of Health of the Slovak Republic No. 448/2007 Coll.

• Category 1 — the degree of health risk is acceptable; there is no risk of damage to health.
• Category 2 — an adverse response of the body cannot be ruled out, but the factors do not exceed the limits.
• Category 3 — high degree of risk; exposure cannot be reduced below the limit by technical measures, and organisational measures and OOPP are required.
• Category 4 — very high degree of risk; work may be classified for a maximum of one year.

The classification of work into categories 3 and 4 is decided by the competent regional public health authority on the basis of a proposal submitted by the employer in cooperation with the occupational health service. Without correct categorisation it is not possible to set the other obligations correctly.

Noise must be assessed and, where action values are exceeded, measured under Government Regulation No. 115/2006 Coll. Vibration is governed by Government Regulation No. 416/2005 Coll. When an action value is exceeded, a programme of technical and organisational measures and health surveillance is triggered; when a limit value is exceeded, exposure must be reduced below the limit without delay.

Measurements of the magnitude of the factors are carried out by qualified persons or accredited laboratories. Records of vibration assessment and measurement are retained for 20 years. Noise and vibration are both factors in the categorisation of work.

When working with chemical substances and mixtures (lubricants, coolants, paints, solvents, adhesives), the employer has obligations under several regulations. The placing of chemicals on the market is governed by Act No. 67/2010 Coll. in connection with the directly applicable EU regulations — REACH (EC No. 1907/2006) and CLP (EC No. 1272/2008).

The safety data sheet is a 16-section document which the supplier provides in Slovak for hazardous substances and mixtures (Art. 31 REACH). The employer must make it available to employees and use it to set safe handling procedures. Protection of health at chemical factor workplaces is governed by Government Regulation No. 355/2006 Coll.: a health-risk assessment, an operating procedure, health surveillance and compliance with the maximum permissible exposure limits (NPEL). Employees must be informed before starting work and repeatedly at least once a year.

Dust is a common factor in manufacturing — metallic dust from grinding and welding (welding fumes), organic and inert dust. The limits (NPEL) are set by Government Regulation No. 355/2006 Coll. for both the total and respirable fractions; exposure is compliant only if both values are observed. For inert dust the whole-shift limit is 10 mg/m³.

Measures are preferably technical — local exhaust ventilation, general ventilation, enclosed processes — and only then OOPP (respirators FFP2/FFP3). Dusty work such as welding and grinding is usually classified in category 3. Note that hardwood dust (oak, beech) has been classified as a carcinogen since 2024 under Government Regulation No. 121/2024 Coll.

A manufacturing operation runs numerous items of reserved technical equipment (VTZ) — cranes, lifting platforms, pressure vessels, electrical and gas equipment. An overhead travelling crane is a reserved lifting device under Decree No. 508/2009 Coll.; only a crane operator with a valid certificate may operate it. The crane operator and the load slinger are two separate qualifications.

Both § 17 of Decree No. 508/2009 Coll. and § 16 of Act No. 124/2006 Coll. apply simultaneously; the update professional training for operators is required every five years, failing which the certificate loses its validity. A pre-employment preventive medical examination is required before starting work, and repeated examinations every five years. VTZ inspections and a deadlines register are the most frequent source of fines — which is why it pays to entrust them to a single supplier.

Personal protective equipment (OOPP) is provided free of charge under § 6 ods. 2 of Act No. 124/2006 Coll. and Government Regulation No. 395/2006 Coll. when the risks cannot be eliminated or reduced by technical means, collective protection or the organisation of work. The procedure: risk assessment, selection of suitable OOPP, a list of OOPP provided and records of their handover to each employee.

OOPP must bear the CE mark and are divided according to the degree of risk into categories I (simple), II and III (highest risk — for example respiratory protection and fall protection). Typical OOPP in automotive manufacturing includes welding helmets and gloves, respiratory protection for painting and grinding, hearing protectors, safety footwear and anti-vibration gloves.

Stricter rules under Act No. 355/2007 Coll. apply to employees performing work classified in categories 3 and 4. The employer must arrange an occupational health service (PZS) — either in-house or from a contractor authorised by the public health authority — a health-risk assessment updated at least once a year, and preventive medical examinations.

• Preventive medical examinations — for category 3 at least once every two years, for category 4 at least once a year, and also on starting work and on a change of classification (§ 30e).
• Specialist physician — examinations are carried out by a physician with the relevant specialisation (occupational medicine, clinical occupational medicine and toxicology, occupational health services).
• RÚVZ — the proposal to classify work in categories 3 and 4 is approved by the regional public health authority; all costs are borne by the employer.

Manufacturing operations are high-risk from a fire perspective — welding and grinding (sparks, hot particles), flammable liquids and gases, dust and oil mists, paint shops and battery charging. Fire protection is governed by Act No. 314/2001 Coll. and Decree No. 121/2002 Coll. Locations where flammable substances are processed or stored are designated as locations with an increased fire risk and are subject to special measures.

• Fire protection technician (TPO) under § 9 of Act No. 314/2001 Coll. — preventive fire-safety inspections, OPP documentation, training and professional preparation of fire brigades.
• Welding and other hot work — activities with increased risk; a written order is required before starting, and a fire-safety assistance brigade is appointed where necessary.
• Fire extinguishers once every 24 months (§ 9 of Decree No. 347/2022 Coll.); in manufacturing the type is chosen according to risk (powder, CO₂ for electrical equipment, foam).
• Flammable liquids under Decree No. 38/2026 Coll. (which replaced Decree No. 96/2004 Coll. from 1 April 2026) — storage, handling and labelling.

Fines of up to €8,298 are imposed for breaches of fire-protection obligations under § 59 ods. 1 of Act No. 314/2001 Coll., and up to €16,596 for more serious offences. Fire documentation and training will be arranged by the fire protection technician, tailored to the manufacturing operation.

For suppliers to the automotive industry the decisive standard is IATF 16949 (quality) and customer-specific requirements, while ISO 14001 (environment) is typically mandatory and ISO 45001 (the BOZP management system) is recommended but not strictly required. Carmakers such as Kia, Volkswagen, Stellantis and Jaguar Land Rover manage their supply chains through these standards.

Alpha Safety will prepare the documentation and system for ISO 45001 and support preparation for SCC if you work for the petrochemical industry. Regardless of certification, every company must comply with Act No. 124/2006 Coll. — a certificate does not replace it.

Checks are carried out by the labour inspectorate under Act No. 125/2006 Coll. — in Slovakia eight regional inspectorates operate under the National Labour Inspectorate (NIP) based in Košice. Fines under § 19: for an employer for a breach of BOZP up to €100,000, for a serious breach endangering life or health from €1,000 to €200,000, and for managerial employees up to four times their average monthly earnings.

In the case of a repeated or serious breach the inspectorate may also prohibit the operation of equipment. The most frequently detected shortcomings are overdue VTZ inspections, missing or incomplete risk assessments, outdated employee training and shortcomings in the provision and recording of OOPP. In the event of a fatal accident, criminal liability may also arise.

Alpha Safety is a partner for comprehensive safety of manufacturing and industrial operations across Slovakia — from the categorisation of work to preparation for customer audits.

• Categorisation of work and PZS — health-risk assessment, categorisation, health surveillance and medical examinations for hazardous operations.
• Factor measurements — coordination of noise, vibration, dust and chemical factor measurements by accredited laboratories.
• BOZP — risk assessment of machines and production lines, documentation, operator training, OOPP records.
• VTZ inspections — cranes, pressure, electrical and gas equipment with a central deadlines register.
• ISO 45001 and SCC — preparation of documentation and the system for certification for tenders and customers.

Manufacturing companies most often contact us when expanding production or when a new customer requiring certification comes on board. We typically address the consolidation of fragmented agendas from multiple suppliers, completion of categorisation and measurements, and the setting up of a VTZ inspection-deadline register.

Companies with a system in place — categorisation, deadline monitoring and prepared documentation — pass both inspections and customer audits without sanctions and production downtime.
