The MSDS for every chemical in your lab must be available to you. We have them available in paper form, but the quickest and easiest way to access MSDS is via the Internet. A computer is available in the stockroom office specifically for this purpose.

slide9

Material Safety Data Sheets (MSDS) for any chemical give information regarding hazards, reactivity, and disposal. MSDS are available in hard copy upon request, or electronically from the following web-sites:

www.hazard.com

www.fisherSci.com

www.sigmaaldrich.com

acs required comprehensive report for research
ACS-Required Comprehensive Report for Research
  • “A student using research to meet the ACS certification requirements must prepare a well-written, comprehensive, and well-documented research report including safety presentations.”
  • Address MSDS safety information regarding handling and disposal; address safety issues particular to your research project.
remember safety glasses
Remember Safety Glasses!

Your eyes are important.

Please wear safety glasses!

gloves
Gloves
  • When using gloves, make sure that the composition of the glove will not allow the chemicals I am using to penetrate the glove. Latex gloves work well for aqueous solutions and pathogens, but the blue nitrile gloves have better resistance to organic solvents.
slide15

CAUTION

For the safe operation of this safety shower and eyewash station, please remove any electronics from the vicinity and do not store anything below them.

slide16

The main function of a fume hood is to exhaust gases that are generated in the hood to the outside.

slide17

Make sure the exhaust blower is operating.

Do not put your face inside!

Minimize storage of chemicals.Close sash when not in use.

Clean spills immediately.

Work with the sash at the proper operating level.

Use emergency purge if needed.

the stockroom is a common area
The stockroom is a common area…

"Picture a pasture open to all. It is to be expected that each herdsman will try to keep as many cattle as possible on the commons.... As a rational being, each herdsman seeks to maximize his gain. Explicitly or implicitly, more or less consciously, he asks, 'What is the utility to me of adding one more animal to my herd?'"

The Tragedy of the Commons, Garrett Hardin, Science, 162(1968):1243-1248.

urgent notice
Urgent Notice!

There is a new system for borrowing chemicals:

If you borrow a stock chemical (not mixed solutions), you must fill out a borrow card with the following information and place it on the shelf in place of the borrowed chemical:

- Chemical Name

- Your Name

- Your Professor’s Name

- Room in which the chemical will be used

**Borrow cards are NOT necessary for solutions unless it is a stock bottle.

security notice
SECURITY NOTICE

THE STOCKROOM IS A

RESTRICTED AREA.

DO NOT OPEN THE DOOR TO ANYONE OTHER THAN UCA PERSONNEL AND APPROVED STUDENTS.

IF YOU ARE UNSURE, CONTACT THE MAIN CHEMISTRY DEPARTMENTAL OFFICE BEFORE ALLOWING ACCESS.

chemical waste
Chemical Waste
  • Waste containers must be labeled with the following:
    • Name of waste (solute & solvent)
    • Estimated amount of waste
    • Estimated concentration of solute(s)
    • Experiment in which the waste was generated (if applicable)
safe storage corrosives
Safe Storage: Corrosives

Corrosives

Examples: thionyl chloride, bromine, sulfuryl chloride, benzoyl chloride, triethyl amine, trihydrofluoride, benzene sulfuryl chloride

safe storage acids
Safe Storage: Acids

Oxidizing Inorganic Acids

Examples: sulfuric, nitric, chromic, and perchloric acids

Organic acids &

Non-oxidizing Inorganic Acids

Examples: acetic, butyric, and formic acids;

hydrochloric, hydrofluoric, hydrobromic, hydroiodic,

and phosphoric acids

chemical storage
Chemical Storage
  • Inorganic chemicals and solutions are organized alphabetically by chemical name, NOT chemical formula.
    • Eg. NaCl would be filed with S, for sodium chloride, not N.
waste storage
Waste Storage
  • There are areas in the stockroom set aside for specific types of waste (see next slide).
  • To store waste containers until the following year, ensure that waste containers:
    • Are labeled appropriately
    • Are tightly sealed
  • If the waste chemical should be kept cool, please store with the refrigerator waste.

chemical storage1
Chemical Storage
  • Incoming chemicals must be labeled with the following:
    • Date received
    • NFPA hazard diamond (if not labeled by company)
empty chemical containers
Empty Chemical Containers
  • These metal trash cans are for empty glass chemical containers. “Empty” is defined as less than 2.5 cm of residue or less than 3% of the total weight. Depending on the chemical, use water or an organic solvent to rinse the container before placing in a metal trash can. If the chemical is hazardous (toxic, corrosive, reactive, or highly flammable), collect the rinse and place in a labeled chemical waste container.
transporting 4 l containers
Transporting 4-L Containers
  • Take care when transporting chemicals and use rubber carriers for glass, 4 L containers.
mercury safety
Mercury Safety
  • If elemental mercury is spilled, notify your research advisor immediately for safe cleanup and disposal.
nmr safety
NMR Safety
  • Keep ferromagnetic objects away from strong magnetic fields, such as near our Nuclear Magnetic Resonance (NMR) instrument.
check the label
Check the Label!
  • Check the label on each chemical container before using it to make sure it contains what is needed for the experiment. Only take as much of the chemical as is needed for the experiment at hand.
fire safety
Fire Safety
  • If a small fire is confined to a container, I will allow it to burn until the fuel has been exhausted or cover the container. If there is a small fire that is not in a container, use a fire extinguisher. If there is a large, open fire, leave the area immediately and notify others. If clothing is on fire, Stop, Drop, and Roll (not run!).
  • New fire blanket instructions posted.
flammables and open flames
Flammables and Open Flames
  • Do not use an open flame in the vicinity of flammable organic solvents.
flammables open flames
Flammables & Open Flames
  • Do not store oxidizers near flammables with an NFPA rating of 2 or above.
gas cylinder safety
Gas Cylinder Safety
  • Check for leaks in gas cylinder connections, make sure that gas cylinders are strapped to the wall, and used a cylinder cart for transporting gas cylinders (with caps).
liquid nitrogen safety
Liquid Nitrogen Safety
  • Recognize that at the temperature of liquid nitrogen (77 K), oxygen in the atmosphere condenses and might react with chemicals in the container or liquid nitrogen trap to form a potentially explosive mixture.
  • Do not use liquid nitrogen in a small, confined space since the nitrogen can displace oxygen in the air and result in asphyxiation.
