General ProceduresGeneral Procedures• General/lab specific

procedures for safe handling and use of chemicals– Wear perpsonal protective

equipments• Goggles, lab coats, gloves,

long pants, closed-toe shoes– Handle with attention and care

• Physical and health hazards of chemicals (acute and chronic) used in the lab– Conduct experiments with

solid or liquid volatile toxic substances that generate aerosols in a fume hood

– Wash hands and arms immediately. No food in areas where toxic substances are being used

Lab Coats Gloves

Chemical StorageChemical Storage• Where and how chemicals are

stored in the lab– All flammables are stored in

the yellow cabinets and in the compartments underneath the fume hoods

– All acids/bases are stored in the compartments underneath the fume hoods

• Methods used to detect the presence or release of hazardous chemicals– Continuous monitoring

conducted by the employer (PRC, CPE, UT…)

– Visual appearance or odor of hazardous chemicals when being released

Flammables & acids/bases Flammables

Chemicals that needto be stored chilledcan be placed in alab refrigerator

Symptoms if Exposed to Hazardous ChemicalsSymptoms if Exposed to Hazardous Chemicals

• Hydrocarbons, alcohols, ethers, esters, and ketones– Inhalation: headache, fatigue, dizziness,

drowsiness, unresponsiveness– Ingestion: slight gastro-intestinal irritation,

dizziness, fatigue– Skin contact: dry, cracked, and chapped skin– Eye contact: stinging, watering eyes, and

inflammation of the eyelids

First Aide and Emergency ResponseFirst Aide and Emergency Response• Generally speaking, leave

the area with an accompany and get medical attention

• Eye exposures: flush the eyes with eyewash for at least 15 minutes and get medical attention

• Dermal exposures: remove clothing and other accessories from the affected areas. Flush with water for at least 15 minutes and get medical attention

Eye-wash, inspected monthly First aid

OSHA Permissible Exposure Limits (PEL)OSHA Permissible Exposure Limits (PEL)• A PEL is a time Weighted Average (TWA)

concentration that must not be exceeded during any 8-hr work shift of a 40-hr work week

• OSHA PEL of typical lab chemicals can be found in the Appendix VIII of Laboratory Safety Manual, which is located as you walk into the lab 1.504

• Some common chemicals (PEL in ppm)– Acetone (1000), ammonia (35), CO (50),

dichloromethane (500), ethanol (1000), hexane (500), methanol (200), osmium tetraoxide (0.0002), THF (200), etc…

Material Safety Data Sheets (MSDS)Material Safety Data Sheets (MSDS)

• MSDS can be acquired through– Chemical manufacturer– Office of Environment Health and Safety– UT Mainframe Computer System (UTCAT)

• MSDS provides information to work with chemicals safely

• MSDS data sheet should be found in the lab with your chemicals, or online on EHS website, http://www.utexas.edu/safety/ehs

Procedures for disposing of waste chemicals

Formseverywhere

Pumps, Gas cylinders, and Cryogen VesselsPumps, Gas cylinders, and Cryogen VesselsCompressed gas cylinders must be secured at all times,with their labels facing out and with safety caps screwedon during storage and transportation

Vacuum pumps are better equipped with cold traps to avoid water from entering the system

Wear gloves andgoggles to prevent cold burns or frost bites

Sharps and Glass ContainersSharps and Glass Containers

When the sharps container is full, fill up and fax the “Bio Waste and Sharps Request for Disposal” formto EHS (512)471-16918. Does not have to bepre-treated.

Custodial services will take away ¾ full of these waste glass cardboard boxes
