Essential safety and precautions when cleaning historic buildings in Bordeaux

Secure facades essentially require controlling the risks associated with cleaning old buildings. The complexity of the operations, the height of the buildings, and the fragility of the stone and plasterwork require a rigorous safety protocol. In Gironde, this risk is amplified by the presence of protected areas and historic buildings in Bordeaux requiring meticulous work. Here are the key elements to consider for optimal safety: 🛡️ Mandatory use of appropriate personal protective equipment (PPE) for operators: helmets, harnesses, gloves, and non-slip shoes. 🛡️ Installation of secure scaffolding or motorized cradles, adapted to the building configuration and working height. 🛡️ Regular equipment checks to prevent accidents and avoid surface damage during handling.🛡️ Specific training for teams working on historic monuments to master safety techniques and comply with conservation regulations.

🛡️ Coordination with the Bordeaux municipality to warn the public and manage traffic and access to work areas. Cleaning facades must also ensure the safety of passersby.
