This is the basis of work performed at height. In each company, employees must be provided with appropriate working conditions, which will mean for them “safe performance of their duties” to the greatest possible extent. There are of course occupations less and also more exposed to a possible risk of an accident. However, we always try to minimize them. This is also the case with work at height. Before the scaffolding is released for use, it must be very carefully checked. A commission acceptance of the structure from the contractor by the user is performed. It must have complete protection and all other elements ensuring the stability of the structure. Anyone who works on scaffolding should be trained and appropriately qualified. It happens that due to the specificity of work, we cannot provide employees with collective security. Then each of them must be secured with personal protective equipment.
