Introduction

This document provides guidance for establishing Safety Data Sheets (SDS) for man-made nanomaterials (and materials or products containing man-made nanomaterials).

The document refers to the document on dangerous goods in the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). Safety Data Sheets.

The relevant technical content of GB 13690-2009 is consistent with GHS, classifies the hazards of chemicals, and carries out the publicity of hazards of chemicals.

Regulation.

Currently, hazard information for most nanomaterials is insufficient. Since the toxicological effects of nanomaterials are not fully understood, and exposure to

Detection is difficult, so in most cases the health risks to workers and potentially exposed populations are unknown. most hazard information

and information exchange systems require the preparation of SDSs for chemicals, including hazardous chemicals containing nanomaterials, during manufacture, storage, transport or other

used in professional activities. However, only a few SDSs contain nanomaterial-specific information or are specific to specific nanomaterials. most

The SDS lacks information on the potential hazards of nanomaterials (see Ref. [78]). Previous studies have shown that compared to bulk (non-nanometer-sized) materials

Some nanomaterials with the same composition are more harmful (such as more biologically active), resulting in greater toxicity. Therefore, SDS needs

Including characterization predictions for the potential safety and toxicity of man-made nanomaterials. While there are currently no legal requirements for

However, since SDS is a recognized and valid method of providing health and safety information in the workplace, it is

It is appropriate to establish an SDS for nanomaterials.

This document considers the precautionary measures of toxicity and other risk factors of nanomaterials, so whether the material is harmful or not, it is recommended as

Nanomaterials and products containing nanomaterials are provided with SDS, unless there is evidence that the material is harmless, or is not harmful during processing or use

3 Terms and Definitions

GB/T 32269-2015, GB/T 30544.1-2014, GHS.2011 and the following terms and definitions apply to this

document.

3.1

Agglomerates agglomerate

An accumulation, aggregate, or mixture of the two of weakly bound particles, whose external area is similar to the sum of the surface areas of its individual particles.

NOTE 1.The forces supporting the aggregates are all weak forces, such as van der Waals forces or simple physical entanglements.

Note 2.Agglomerates are also referred to as secondary particles, while source particles are referred to as primary particles.

[Source. GB/T 32269-2015, 3.2]

3.2

Aggregate

New particles formed from strongly bound or fused particles may have an external surface area significantly smaller than the sum of the individual particle surface areas.

Note 1.The forces supporting the aggregates are all strong forces, such as covalent bonds or originating from sintering or complex physical entanglements.

Note 2.Aggregates are also referred to as secondary particles, while source particles are referred to as primary particles.
