The goal, according to OSHA was to establish “a consistent user-friendly 16 section format” for Safety Data Sheets. This is a worthy goal as the purpose of safety data sheets is to provide valuable safety information in case there is some type of emergency such as a fire or chemical exposure.

Have you ever really looked at the MSDS or SDS that you receive? They are anything but user friendly.

Let’s Talk About Significant Figures

In this post, I want to talk about the proper way to express test results on certificates of analysis. To explain this, I am going to talk about the concept of significant figures (or significant digits). What are significant figures?

According to Wikipedia:

“The significant figures of a number are digits that carry meaning contributing to its measurement resolution.”

Confused? Let me explain.
