If you are unsure whether a material is flammable, where should you check?

• A. Safety data sheet
• B. MSDS and manufacturer's label
• C. Customer service desk
• D. Marketing brochure

Answer: (B)

The main idea is to know where to find reliable information about a material’s flammability. The best place is the combination of the Material Safety Data Sheet (MSDS/SDS) and the product’s label from the manufacturer. The SDS (formerly called MSDS) offers detailed hazard information, including flammability classification, flash point, safe handling and storage, and recommended fire-fighting measures. The manufacturer’s label provides immediate, at-a-glance warnings and hazard symbols right on the container. Together, they give both quick reference and in-depth safety data, making this combination the most dependable source.

Relying on just the safety data sheet is solid, but the label is essential for quick checks when handling the material. A customer service desk isn’t the primary source for accurate safety information, and a marketing brochure isn’t a reliable source for hazard details.
