Essentials of Laboratory Safety

Before Lab Work, Get to Know: Hazards of materials & agents and their prescribed safety procedures

Also Get to Know: Emergency spill procedures, use of adsorbents and disinfectants Designated escape route and alternate Location of fire ext., eye wash, shower, first aid, and spill kits

Before Lab Work, Get to Know: Emergency telephone numbers and reporting procedures For emergencies requiring internal assistance call: 1111

Before Lab Work, Get to Know: Emergency telephone numbers and reporting procedures For all emergencies call: 1111

While Working in the Lab: Shoes with full coverage and good grip soles Restrain long hair, loose clothing and jewelry Use appropriate eye, skin, and hand protection

Eye protection Protects against risk of flying objects or dust particles, splashes of hazardous materials or harmful rays

Safety Glasses Unbreakable lenses of plastic or tempered glass For light-to-moderate work Can be prescription lenses Do not interfere with contact lenses

Goggles Work with significant risk of splash of chemicals or projectiles Can be worn over prescription glasses

Face Shield Work with significant risk of splash on face or possible explosion Face shield protects face adequately but not eyes

Hand Protection Protects against risk of cuts, abrasions, burns, or exposure to hazardous materials. Requires selection of the appropriate chemical resistant gloves

While Working in the Lab: Follow universal precautions Handle unknowns as if they were hazardous

While Working in the Lab: Handle volatiles in a chemical fume hood Contain bioaerosols in a biological safety cabinet

While Working in the Lab: Use mechanical transfer devices

While Working in the Lab: Authorized persons only Identify EVERYTHING! No food, beverages, tobacco products, or application of cosmetics

While Working in the Lab: Report all: Accidents Injuries Fires Spills Close calls 1 Disabling injury 10 Minor injuries 30 Property damage incidents 600 Close Calls

Before Leaving the Lab: Turn off: Gas Water Power supplies Vacuum lines Compression lines Heating apparatus

Before Leaving the Lab: Identify and package waste, dispose properly Lock/out and tag/out defective equipment Decontaminate work surfaces and equipment

Before Leaving the Lab: Return unused equipment, apparatus, etc. Leave lab coat in the lab Wash Close and lock door

Evaluating Lab Hazards Regular review of the types of hazards: chemical physical biological ergonomic mechanical Minor Variation in Procedure

Weekly Lab Checks Eye wash (purge) Fire extinguisher First Aid Kit Fume Hood Tubing, pressurized connections Chemical storage
