Laboratory Storage Checklist

Lockable doors – no deadbolts

Ventilation – at least 6 changes per hour

Temperature – should not exceed flash point including summers

Shelves/cabinets – secured to walls - max height of six feet – corrosion resistant

ABC Fire extinguisher/blanket near storeroom exit

Class D fire ext. for Reactive metals such as sodium, magnesium, etc.

Eyewash/shower within 25 feet

Ceiling-mounted smoke or fire detective with outside alarm

Dedicated cabinets for flammables and acids

Spill Control Kit – Chemical splash goggles, chem-resistant gloves, appropriate neutralizing materials and absorbent material, plastic bags, and scooper

Separate lockable storage for highly toxic and hazardous chemicals not on standard inventory list

Dedicated refrigerator for storage of volatile flammable materials or biological specimens

Chemicals should be arranged in compatible families, NOT IN

ALPHABETICAL ORDER

Store no more than needed for ONE YEAR

More than 10 gallons of flammable or combustible liquids must be stored in NFPA cabinet – if cabinet is vented, ductwork must be fire-resistant

Storerooms should not be used as prep rooms for repackaging or preparing solutions

New chemicals should be stored promptly and correctly

Do not store chemicals in aisles, stairwells, on desks, lab benches, on floors, in hallways, in fume hoods, or in cabinets in rooms other than the chemicals storage room

Maintain a complete inventory ANNUALLY

Mark the acquisition dates on all containers – dispose of peroxide forming chemicals after six months

Do not store chemicals on shelves above eye level or below knee level

Do not crowd bottles on shelves so that some containers must be moved in order to retrieve desired container

Inspect bottles annually and dispose of bottles showing signs of corrosion or leakage

Gas cylinders must be secured in place with protective caps

Store cylinders away from heat and sunlight

Air pressure in laboratory will be slightly negative

Fume hoods – maintenance

Master cut-offs for gas and electricity

First aid kit

Fire alarm actuator

Telephone

Means to sterilize goggles and other protective eyewear

Flammables

Conditions for storage:

 Store in a cool place away from heat, sun or sources of ignition

 Automatic fire detection equipment

 Adequate ventilation to prevent vapor buildup

 Approved Storage Cabinets and safety cans

 Ground metal containers

Store away from:

 Oxidizers

 Chemicals capable of spontaneous heating

 Explosives

 Materials that react with air or moisture to liberate heat

 Ignition sources

Corrosives

Conditions for storage:

 Separate acids from bases

 Separate oxidizing acids (e.g., nitric acid) from other acids

 Cabinets should be non-corroding or covered with fume resistant paint.

 Corrosives should not be stored above eye level

 Use bottle carriers for transporting containers of corrosives

 Have spill control pillow and neutralizing materials readily available

Store away from:

 Toxic materials

 Active metals (sodium, magnesium, etc.)

 Substances that release corrosive, toxic or flammable fumes on reaction

 Organic materials

 Flammable substances

 Uncoated structural material

Toxic Chemicals

Conditions for storage:

 Store away from heat, moisture and fire hazards

 Protect from contamination with acids and fumes.

Store away from:

 Acids and other corrosives

 Reactive chemicals

 Fire hazards

 Heat

 Moisture

Reactive Chemicals

Condition for Storage:

 A fire Sprinkler, except where water sensitive chemicals are stored

 Protect from extremes of temperatures

 Store oxidizers away from flammable or combustible materials, and away from reducing agents such as zinc and alkaline earth metals

 Store peroxide-forming chemicals in airtight containers and label with receiving and disposal dates (can form explosive peroxides which can be detonated by shock or heat)

 Store light sensitive chemicals in amber bottles.

Store away from:

 Organic materials

 Flammable materials

 Corrosives

 Toxic materials

Water and Air Sensitive Chemicals

Conditions for storage:

 Store in waterproof, fire-resistant cabinet or room

 Smoke and/or heat detector should be provided in storage areas

 Eliminate all ignition sources

Store away from:

 Water and moist air

 Solution of aqueous acids and bases

 Flammable storage area

 Reactive chemicals
