Fume Hoods
Work with the sash at 10-12
inches
Work 6 inches inside the
face of the hood
Prevent excessive movement
near the hood
Raise any equipment 1-2
inches off the flat surface of
the hood
Keep 1-2 inches of space in
front of the hood baffle
Fume hoods are tested
annually by ESD
Average face velocities should
range between 100-120 feet
per minute (fpm)
Do not use power strips inside
the hood
Keep doors and windows
closed
Do not clutter hood with
chemical storage and
equipment

ACCIDENTS & INJURIES
• Keep Eyewash Stations and Safety Showers
unobstructed and functional
• Make sure First Aid Kits are present and
properly stocked
• Fill out an Incident and Accident Report and a
First Report of Injury form
• SEEK MEDICAL ATTENTION
CHEMICAL SPILLS
Contact ESS in the event of ANY spill

•
•
•
•
appropriate materials are not available
chemical or level of hazard is unknown
PPE is not available
proper training has not been received
CHEMICAL SPILLS
Identify chemical
Look for injuries
Alert others

CHEMICALS
Chemical Storage Codes
General Guidelines for
Chemical Storage
•Store hazardous materials below shoulder
height
•Store by hazard classification
[color codes]
•Shelving: well anchored/chemical resistant
SOLVENTS
• Solvents include variety of
chemicals -- hazards:
Toxins
Flammables
Non-Hazardous
• Most solvents handled in
research laboratories are
flammable liquids
FLAMMABLE LIQUIDS
• Use approved flammable storage cabinets
• 20 gallons per 100 sq.ft. - fire separation
• 10 gallons outside of approved cabinets or
safety cans
• 120 gallons maximum storage for any lab
• Approved refrigerators/freezers only
The Fire Triangle
FLAMMABLE LIQUIDS
Flashpoint:
min. temp. at which
a liquid gives off enough
vapor to ignite
Vapor Density:
ratio of vapor vs. density of air
Air = 1
<1 = lighter than air
>1 = heavier than air

TOXINS
• Store according to the
nature of the chemical
• Appropriate security may
be necessary for some
toxins
• OXIDIZERS:(nitric acid)
Store away from flammables, combustibles, reducers
• WATER-REACTIVES:(sodium)
Store in cool dry place
Do not store under sinks, above water baths…
Class D fire extinguishers
• PEROXIDE-FORMERS:(THF, ethyl ether)
Store in airtight containers in cool, dry place
