This post was originally published in March 2017 and has been updated in May 2022 for accuracy.

Safety Data Sheets Defend Your Employees

Chemical Safety in the workplace can be a topic most employers would like to avoid. However, not only is it vital to the employee’s and community’s wellbeing, it is a requirement by law. In comes Safety Data Sheets (SDS) to the rescue! If Chemical safety in the workplace was a hockey team, training, storage requirements, purchasing, disposal, and inventory requirements would make up the Center, Forwards, and Defense, leaving the cornerstone of any hockey team, the Goalie to represent Safety Data Sheets (SDS). OSHA Standard 1910.1200 (g)(8) states that The employer shall maintain in the workplace copies of the required safety data sheets for each hazardous chemical, and shall ensure that they are readily accessible during each work shift to employees when they are in their work area(s). However without correct understanding of Safety Data Sheets, it would be like having an injured goalie in your starting lineup. Below are some tips for reading a 16-section format SDS.
