How to Read A Safety Data Sheet (SDS)
Safety Data Sheets (SDS) are an important requirement of the OSHA Hazard Communication Standard. SDS are essential documents that are used to inform employees, students, and the general public about how materials can be safely handled, used, and stored. Since Flinn provides chemicals only to schools, we have written Flinn SDS specifically for instructors and their students. Using clear and straightforward language, each Flinn SDS provides all the relevant safety and hazard information in a consistent, useful, and easy-to-read two-page format. Flinn SDS follow the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). The 16 sections are divided into four major areas, each designed to answer a specific question.
What is the material and what do I need to know immediately in an emergency?
Sections 1–3.
A It is important that the chemical name
on the label match the name on the SDS. Many chemicals have similar names, but very different properties.
B The most important section! Provides an overview of the physical and health hazard risks associated with using the material.
C Signal words, either Danger or Warning, heighten the awareness of the relative risk when using certain chemicals. Danger is the more severe warning!
D Eight pictograms exist in the GHS classifica- tion scheme to call attention to physical and health hazards. See page 206 for more information about GHS pictograms.
E This section includes the formula, formula weight, concentration, and CAS#. The CAS# is the single identifying number for each specific substance. CAS# should match the CAS# on the bottle label.
What should I do if a hazardous situation occurs?
Sections 4–6.
F Seek medical attention. These first-aid measures are only meant for immediate first aid and should always be followed up with profes- sional medical care. The CAS# is the single identifying number for each specific substance. CAS# should match the CAS# on the bottle label.
G This section is written for the firefighter. Flash point (the lowest temperature at which enough vapor is present to form an ignitable mixture with air); upper and lower flammable limits; and the auto ignition temperature (AIT) are common prop- erties included in this section.
H The NFPA code is a numerical code estab- lished by the National Fire Protection Association. It rates the substance under fire conditions in four categories. Health, Flammability, Reactivity,
and unusual reactivity: 4 is a severe hazard, 0
is no hazard.
I How to clean up a spill. Always remove unprotected personnel from area and make sure all students are safe. Contain the spill with sand or absorbent materials.
