The temperature of the premises, the speed and the relative humidity of the air shall be calculated and settled in relation to each other in such a way that the climate of the premises is adapted to the nature of the work and is not detrimental to health.

¹ In the rooms ventilated naturally, the windows in front and the zenithals must be arranged in such a way as to permit a slight permanent ventilation as well as a rapid renewal of the air.

² In the artificially ventilated premises, the adduction and evacuation of air must be regulated in relation to the other and adapted to the nature of the work and the type of operation. It will be important to avoid annoying air currents.

³ The exhaust air may be reintroduced to the premises only if this operation is not detrimental to the health of the workers.

Workers must be protected against excessive sunlight and excessive calorific radiation caused by operating facilities or work processes.

Where work is to be carried out in unheated premises, in buildings partially open or in the open air, the measures necessary for the protection of workers against the cold and the weather must be taken. In particular, it is as important as possible to ensure that every worker can warm up at his or her work station.

¹ Noise and vibration must be avoided or combated.

² For the protection of workers, it is particularly important to:

A.

Take action on building construction;

B.

Take action on operating facilities;

C.

To perform acoustic insulation or isolation of sources of noise;

D.

To take measures concerning the organisation of work.

Workstations and equipment must be designed and constructed in accordance with the principles of ergonomics. The employer and the workers shall ensure that they are used appropriately.

¹ The free space around workstations must be sufficient to allow workers to move freely during their activities.

² Permanent workstations must be designed in such a way as to allow workers to adopt a natural position of the body. Seats must be comfortable and suitable for the work to be done and the worker. If necessary, armrests and footrests will be installed.

³ Workstations shall be arranged in such a way as to enable workers to work, if possible, seated or alternately seated and standing. Those who are to work standing will have seats that they can use from time to time.

⁴ Workstations shall be arranged in such a way that the operating facilities or neighbouring depots are not detrimental to the health of the workers; to this end, appropriate measures should be taken, such as The installation of protective walls or the fitting of workstations in separate premises.

⁵ Workers must be able to benefit from the view on the outside from their permanent work station. In rooms without front windows, permanent work stations are permitted only if specific construction or organisational measures ensure that health protection requirements are generally met Respected.

¹ The employer shall take appropriate organisational measures and shall make available the appropriate equipment, in particular mechanical devices, to prevent workers from having to move loads manually.

² Where the displacement of loads can only be carried out manually, suitable means shall be made available and used for lifting, wearing and moving heavy or bulky loads to allow for handling That is safe and that preserves health.

³ The employer must inform workers of the risks associated with the movement of heavy or bulky loads and how to lift, carry and move loads properly.

⁴ It must inform workers of the burden and its distribution.

¹ It is prohibited to use monitoring or control systems to monitor the behaviour of workers at their work station.

² Where surveillance or control systems are necessary for other reasons, they must, in particular, be designed and arranged in such a way as not to affect the health and freedom of movement of workers.

¹ If technical or organisational measures do not, or only partially, prevent any harm to health, the employer must make available to the workers individual protective equipment which must be That the port may be reasonably required of the workers. They must ensure that they can be used at all times in accordance with their intended use. ¹

² Individual protective equipment is in principle intended for personal use. Where circumstances require the use of individual protective equipment by more than one person, the employer must take the necessary measures to ensure that the protection of health is maintained.

³ Where several individual protective equipment is required simultaneously, the employer shall ensure that they are compatible and that their effectiveness is not compromised.

When working clothes are heavily soiled by foul-smelling materials or other materials used in the company, the employer will be responsible for cleaning them at appropriate intervals.

¹ The provisions applicable to the development and use of the working premises are also, by analogy, to changing rooms, showers, sinks, toilets, refectories, living quarters and infirmaries.

² All facilities listed in para. 1 must be maintained under conditions of the protection of irreproachable health.

³ Cloakrooms, washbasins, showers and toilets will be arranged separately for men and women. At the very least, a separate use of these facilities will be planned.

¹ A sufficient number of facilities adapted to the circumstances will be made available to the workers so that they can change and drop their clothing. These locker rooms will be set up in premises reserved exclusively for this purpose and, if possible, sufficiently ventilated.

² Every worker will have either a sufficiently spacious and aerated wardrobe, an open wardrobe and a locked locker. If necessary, work clothes should be able to be dried and stored in such a way as to be separated from the city's clothing.

¹ Appropriate washbasins, as a general rule of hot water and cold water, as well as adequate cleaning products will be made available to workers in the vicinity of work stations and changing rooms.

² Suitable showers with hot water and cold water must be installed in sufficient numbers close to the changing rooms when the workers perform dirty work or are exposed to a high heat.

³ If showers or washbasins are separated from the locker rooms, they should be easily communicated to each other.

¹ Workers must have a sufficient number of toilets in the vicinity of workstations, rest rooms, cloakrooms and showers or washbasins.

² The number of toilets is a function of the number of workers employed simultaneously in the company.

³ The washroom will be sufficiently ventilated and will be separated from the work space by aerated vestibules.

⁴ Appropriate facilities and equipment for washing and drying hands should be located near the washroom.

¹ In case of need, in particular when working at night or in teams, workers must be able to have adequate and calm refectories and living quarters; these must, if possible, be lit naturally, give out on the outside And be separated from workstations.

² If the work requires the presence of workers in the working premises as during breaks, adequate seating must be made available to them.

³ Where necessary, rest spaces shall be provided.

⁴ When workers are regularly and frequently required to provide continuous service and there are no rest facilities, other rooms must be made available for them to stay there.

Pregnant women and nursing mothers must be able to lie and rest under adequate conditions.

¹ Drinking water will be available in the vicinity of the workstations. Where the working conditions so require, workers must also be able to obtain other non-alcoholic beverages.
