Indoor Air Quality (IAQ) Practice Exam

Material Safety Data Sheets (MSDS), now referred to as Safety Data Sheets (SDS) under the Globally Harmonized System (GHS), are required for chemicals that present potential hazards in the workplace. The requirement for an SDS is generally triggered when a hazardous chemical constitutes more than 1% of a product's content. This threshold is established to ensure that workers are adequately informed about the risks associated with chemicals they may be exposed to during their work.

When a chemical is present in concentrations higher than 1%, there is a potential for significant risk that warrants detailed information regarding the handling, storage, and health effects of the chemical. This information is crucial for maintaining a safe working environment and for informing safety protocols. In contrast, chemicals below this concentration generally do not require the same level of detail in their safety documentation, as the risk they present is considered minimal.
