New health and safety measures in the renovation work on L4 of Barcelona Metro

COMSA Corporación has implemented new preventive health and safety measures in the comprehensive track and drainage renovation works on the Barceloneta-Verdaguer section of L4 of the Barcelona Metro. With the aim of minimising the exposure of workers to silica dust particles and diesel fumes – typical elements of the railway environment – the company has applied several initiatives, including the following:

– Design and implementation of an in-house ventilation strategy during the execution of the works, including windbreaks, water mist systems and additional portable ventilation systems.

– Continuous watering of the ballast to minimise dust generation.

– Implementation of changing rooms with double lockers so that workers have one locker for clean clothes and another for dirty clothes.

– Daily industrial cleaning service for work clothes and facilities.

– Use of long-sleeved work clothes and FFP3 protective masks.

In addition, during the development of the works, measurements of both silica dust and diesel fumes have been carried out periodically at different work points and facilities.
