Chemical Storage Guide
individual hazards and mixed hazards
Flammability
The ability to ignite and burn easily
Organic solvents, hydrocarbons.
hydrocarbons
Hazard Control
flammable storage cabinets
Toxicity
Harmful to human health
Heavy metals
cause acute or chronic effects
organophosphates
flamabble and combustibles
Characteristics
easily ignited
may present a serious fire and explosion
hazard.
Laboratory Chemicals
Gases
Solids
Liquids
Combustible liquids
Storage limits
Quantity Limits outside Flammable Storage Cabinets
Quantity Limits within Flammable Storage Cabinets
Maximum Container Capacity
Storage Precautions
away from all ignition sources:
flammables separate from other hazard classes,
Separate flammable gases from oxidizing gases
corrosives
Carachteristics
Strong Acids
bases can destroy
human tissue and corrode metals.
Laboratory Chemicals
Organic Acids
Inorganic Oxidizing Acids
Inorganic Non-Oxidizing Acids
Bases
Precautions
Segregate acids from bases
Segregate acids from chemicals
Toxics
injury or death
precautions:
tightly sealed
minimize exposures to personnel
segregate toxics from other hazard classes
ventilated area
away from light and heat
cool area
manage
toxic gases
pyrophoric gases
highly toxic gases
laboratory chemicals
Solids
Liquids
Gases
non-laboratoric chemicals
liquids
solid
Highly toxics
injury or death at low concentrations.
precautions
lowest possible quantities
Use highly toxic chemicals in a designated area or laboratory
segregate toxins from other hazard classes

fire hazard
decompose under certain conditions
store in:
cool place
dry place
Do not store under sink
Segregate oxidizers
combustible
flammable
reducing agents
organic peroxides
inorganic oxidizers
not to contaminate oxidizers
non-laboratory chemicals
gases
liquids
solids
Compressed Gases
gases or mixtures of gases that are contained in a vessel
Under pressures
storage
Store cylinders in a well-ventilated
Clearly label each cylinder with the gas type and any relevant safety informatio
Keep flammable materials away from stored gas cylinders.
Keep cylinders upright to avoid leaks
Pyrophorics
Water reactives
highly reactive substances
safety guidelines
Research and understand local regulations
choose:
cool and dry location
well-ventilated
fire-resistant storage cabinet with secondary containment
away from:
direct sunlight
water sources
heat sources
can cause fires or explosions when exposed to water
Explosive and potentially explosive chemicals
Types of Explosive Chemicals
Primary Explosives
Chemicals
Secondary Explosives
Less sensitive
require initiation
Organic Peroxides:
Unstable compounds
sensitive to shock and heat
Nitrated Compounds
Highly flammable
unstable
AzidesReact
unstable compounds
easily with metals
Causes of Instability
Temperature Sensitivity
Heat can cause decomposition
Shock Sensitivity
friction trigger explosion
Chemical Reaction
Reactive with incompatible substances
Storage Duration
Deterioration over time
increases risk
