Abstract
Madrid’s underground metropolitan transport company (metro) decided to substitute regular plastic paints which contained titanium dioxide, xylene and toluene, by mineral paints based on barium sulfate, quartz and mica that do not represent any health or environmental hazards and require less frequent maintenance.

Hazard Assessment
Titanium dioxide is 2B carcinogen (IARC) as listed in the Substance Database according to SUBSPORT Screening Criteria (SDSC). Xylene is classified as harmful by skin contact and inhalation (H312 and H332), and causes skin irritation (H315). Toluene is classified as reproduction toxic cat. 2 (H361d) and has other toxic effects (H304, H225, H315, H373, H336). The alternative substances have no harmonized classification. However, quartz dust has been classified as a carcinogen cat. 1 by IARC and for this reason it is in the SDSC database.» Check the Substance Database according to SUBSPORT Screening Criteria (SDSC)
Description of Substitution
Introduction The substitution process was carried out in the company Metro Madrid. The company began a series of maintenance works in several facilities and sought an enduring paint that would reduce the frequency of maintenance. The paint regularly used by the company was a conventional plastic paint which contained titanium dioxide (carcinogen), xylene (neurotoxic) and toluene (toxic for reproduction) among other chemicals. The company management decided to substitute it by a mineral-based paint whose components, barium sulphate, quartz and mica are nor hazardous to human health and the environment. Water is used as solvent with these kinds of paints. Toxic hazard was one the reasons that led to substitution. Other reasons included a higher durability and colour stability of the mineral paint, a factor that reduced the frequency of maintenance tasks. The mineral paint also had a good adherence to the surface (wall) and did not become an additional coat as in the case of plastic paint. Durability and transpiration were better which prevented mould and humidity. Substitution was implemented in 2007 in Spain and mineral paints have been used since then. Description of procedure or technology (including pre-/post-processing) Way of application: e.g. spraying, dipping, open/closed system etc. Risk management measures (technical, organizational and personal) Risk reduction by alternative: Human health: e.g. more/less safety measures e.g. technical/operational/personal protection measures Substitution of a hazardous substances based paint by using a water-based mineral paint Risk reduction by alternative: Environment: e.g. waste reduced/increased
Case/substitution evaluation
Case/substitution evaluation Health hazards reduced significantly. The alternative substances have no harmonized classification and the color itself was also not classified by the manufacturer. Since the alternative paint contains quartz in liquid form and not the quartz dust (IARC Carcinogen Cat. 1), it is an appropriate alternative. Advantage or Disadvantage of alternative

A higher durability and colour stability of the mineral paint - a factor that reduced the frequency of maintenance tasks. A good adherence to the surface (wall) – it did not become an additional coat as in the case of plastic paint. Better durability and transpiration which prevented mould and humidity. |
