(2) The health measures which the authorities require of employers must be in proportion to the repercussions they have on the design of the building and on the organization of the undertaking.

Section 3. Specific obligations of employers. (1) Employers must ensure that the effectiveness of occupational health measures is not impaired. They shall check them at suitable intervals.

(2) Employers must adapt health measures to the new conditions of work in the event of alterations to buildings, parts of buildings, technical installations and apparatus or work processes or the use of new products in the undertaking.

(3) When indications make it evident that the tasks carried out by a worker are affecting his health, a medico­occupational inquiry shall he conducted.

Section 4. Expert's report. The authorities may ask employers to submit a report by a technical expert if there are serious grounds for doubting that occupational health requirements are being observed.

Section 5. Briefing and instruction of workers. (1) Employers must ensure that all workers employed in the undertaking, including those from a third party undertaking, are informed and instructed, sufficiently and suitably, about the risks to which they are exposed in carrying out their tasks and also about the occupational safety measures to be taken to avert them. Such instruction must be provided when workers enter into employment and every time that working conditions are modified; it must, if necessary, be repeated.

(2) Employers must ensure that workers observe occupational health measures.

(3) Information training must be carried out during working hours and may not be left to the responsibility of the workers.

Section 6. Consultation of workers. (1) Workers, or their representatives within the undertaking, must be consulted in good time and comprehensively about all matters relating to occupational health. They shall be entitled to put forward proposals.

CHAPTER II. SPECIFIC REQUIREMENTS CONCERNING OCCUPATIONAL HEALTH

Division I. Buildings and workplaces

Section 11. Construction methods. (1) The outside walls and roof shall ensure adequate protection against the weather. When necessary, inside walls and floors shall be insulated against damp and cold.

(2) The building materials used must not present health hazards.

Section 12. Air space. (1) Every worker working in the workplaces shall have a minimum air space of 12 cubic metres; it shall be at least 10 cubic metres when artificial ventilation is adequate.

Section 13. Walls and ceilings. The walls and ceilings inside the buildings must be so constructed that they are easy to clean and that deposits of dust and dirt are minimized.

Section 14. Floors. (1) Floor surfacing must be dust­resistant, not readily soiled and easy to clean. If experience shows that liquids can be spilled over it, arrangements for rapid drainage must be made and, if possible, dry places shall be provided for the workers.

(2) When technical production conditions so permit, floor surfacing must be made of materials which are poor conductors of heat. When only certain workstations are permanently occupied, this type of surfacing need be installed only in such places.

(3) The floor shall be insulated when the temperature below the workplace is appreciably either colder or warmer than that of the workplace.
