MSDSMaterial Safety Data Sheet

• properties of a particular substance• procedures for handling, storing, disposing

or working with that substance in a safe manner

• physical data (melting point, boiling point, flash point, etc.), toxicity, health effects, first aid, reactivity,

• format of an MSDS can vary from source to source (click here for an example)

MSDS – where do you find them?

• Every chemical supplier (Sigma, Spectrum) must provide an MSDS for each product.

• Consumers can see a copy of MSDS if one knows the compound’s name.

• Available onlinewww.chemistry.pomona.edu has a link to “moldata” and “environmental chemistry”

Flammability, health hazard, reactivity, special precautions

Specific Hazard- White SectionOxidizers OXY

Acids ACIDAlkali ALK

Corrosives CORUse NO WATER WRadiation HazardNow let’s go into the lab to review safety…

Flammable - RedSusceptibility to Burning4 Deadly - Flash point is below 73°F

- Very Flammable.

3 Danger - Flash point is below 100°F - Can ignites under normal temperature conditions.

2 Hazardous - Flash point is below 200°F - Ignites with moderate heating.

1 Slightly hazardous -Flash point above 200°F - Ignites when preheated.

0 Normal - Will NOT burn.

Reactive - YellowSusceptibility for Energy Release 4 May detonate under normal conditions.3 May detonate with shock or heat.2 Violent chemical change but does not

detonate.1 Not stable if heated, use precautions.0 Normally stable.

Health Hazard- BlueRecommended Protection 4 Special full protective suit and

breathing apparatus must be worn.3 Full protective suit and breathing

apparatus should be worn.2 Breathing apparatus with full face

mask should be worn.1 Breathing apparatus may be worn.0 No precautions necessary.
