Potential risks posed by the use of nano-enabled construction products: A perspective from coordinators for safety and health matters

Abstract

Abstract: The use of engineered nanomaterials (ENMs) in the construction sector is a newly emerging risk as there is limited knowledge about this topic. This paper studies the potential risk of nano-enabled construction products and how these are being addressed by Coordinators for safety and health matters. Firstly, a compendium of safety data sheets (SDSs) for these products and publications about the potential for nano-exposure were analysed. Secondly, a questionnaire was sent by email to a representative sample of Coordinators in Andalusia (Spain). The key findings were that practically none of the SDSs mentioned nano-specific data and the activities that involve nanomaterials in powder form or for spraying are the riskiest. From the survey, it seems that nano-enabled construction products are widely known about, but the use of nanomaterials is very limited. The nanorisks are unknown and rarely mentioned in work safety documents. It can be concluded that, a potential relationship between hazardous profile of the product and presence of ENMs is excluded. Although the use of nanotechnology in the construction site is at an early stage, workers have already been exposed to ENMs in critical activities and risk management is not being addressed.
