A critical evaluation of the safety datasheets of graphene materials

Graphene, a single layer of carbon atoms, is a material that has held a leading position in material research owing to its excellent properties, allowing its use in innovative technologies. In spite of many advantages, the graphene’s potentially hazardous effect on the environment as well as human health constitutes a major drawback. Year after year, safety data sheets (SDS) constitute the main reference on a material’s potential hazards and the methods to prevent or address them if needed. However, SDS content has been heavily criticized due to incomplete, incorrect, or missing information and the cost required to produce and maintain it. The primary objective of this work is to introduce a stepwise process of knowledge management regarding SDSs, by identifying unexplored or neglected sections in a holistic approach. In this light, this work examines 37 graphene SDS, using modified Hodson’s criteria. The quality evaluation revealed that approximately 5% (2/37) of the datasheets were deemed reliable without restrictions (excellent), the majority 49% (18/37) were categorized as reliable with restrictions (good), while about reaching almost 46% (17/37) were deemed non-informative. It is noteworthy that approximately 73% of the SDS require major improvements; thus, the majority did not provide adequate data to be properly assessed. Section 15 could potentially trigger fundamental changes in the product status. The comprehensive evaluation of all 16 sections will enhance the capacity to conduct research mapping and formulate opinions on nanomaterials, thereby stimulating innovation.
