ConclusionThe authors investigated 177 nanomaterials frequently used in theUS construction industry. The results indicate that 29.9% of thenanomaterials were unspecified and 7.9% were not reported.Due to the potential toxicity of nanomaterials to workers and finalusers, it is crucial for construction professionals to know the nano-materials to which they are exposed. Manufacturers do not makethe SDSs available for 62.7% of nanomaterials. Therefore, the au-thors recommend that construction employers order their workersto avoid direct exposure to nanomaterials. The exposure could be inthe form of inhalation, swallowing, and touching. Therefore, appro-priate personal protective equipment (e.g., gloves and respirators)to mitigate the possible hazard are highly recommended. On theother hand, it is clear that an enforceable intervention by OSHAis required to increase awareness of construction nanomaterials,as well as their potential health impacts. In addition, the manufac-turers of construction materials that utilize nanomaterials shouldinvestigate the possible undesirable health influence of theirmaterial to avoid future nanomaterials-related illnesses claims. Itis also clear such intervention will not be an easy task since thereis little knowledge available about the subject. Accordingly, exper-imental studies are required to test the toxicity and possible trans-formation and fate of nanomaterials during various use stages.Construction scholars and professionals may have little knowledge,if any, regarding the required tests. Therefore, interdisciplinaryresearch efforts are encouraged.
