under pressure including compressed gas,
dissolved gas, or liquefied gas
Compressed Gas Cylinders
• store and transport with safety cap

Flammable Materials
•
Methanol, Toluene, Butane, Ethanol
•
Store liquids in Flammable Storage Cabinet
•
Store minimum quantities in lab
•
Explosion-proof fixtures required
•
Decant in large quantities in fume hood
•
NEVER store with oxidizers
•
Keep away from heat, ignition sources, and direct sunlight
•
Use static lines when transferring
•
Refrigerator must meet NFPA Standard 56C ( Flammable Material
Storage Units)
Class C
• Oxidizing Material
– Any Hazardous Material which causes or
contributes to the combustion of another
material by giving oxygen or some other
oxidizing substance, whether or not it is
combustible.
– Organic Peroxides
Oxidizers
• Chlorates, Nitric Acid, Peroxides, Permanganates,
Perchlorates, Nitrites, Nitrates
• Easily oxidize metal powders, organic materials
• Keep minimum quantities in lab
• Segregate from other materials, such as organic solvents
• Use a glass-heating mantle or sand bath to heat material
• PPE and/or Explosion barriers may be require
Class D1
• Poisonous & Infectious Materials
– Material causing immediate and serious toxic
effects
– Materials which are potentially fatal or may
cause permanent damage if inhaled,
swallowed, or absorbed through the skin, or
may burn the skin or eyes upon contact
Class D2
• Poisonous & Infectious Materials
– Material causing other chronic or long term
effects
– Material which may cause death or
permanent damage as a result of repeated
exposure over an extended period of time;
may be an irritant to the skin, eyes, or
respiratory system; may cause cancer, birth
defects, or sterility.
Class D3
• Poisonous & Infectious Materials
– Biohazardous and Infectious Materials
– Materials which may cause disease in
humans and animals, such as viruses,
bacteria, and fungi; may also include
cultures and diagnostic specimens such as
blood, urine, and body tissue.
Class E
• Corrosive Material
– Material which may corrode aluminum and
steel or human flesh
– Material which are anhydrous corrosive
gases
Class F
• Dangerously Reactive Material
– Materials which undergo vigorous
polymerization, decomposition, or
condensation
– Materials which become self-reactive under
conditions of shock, or increased
temperature or pressure
– Materials which react vigorously with water
to produce a very toxic gas
Chemical Compatibility
• Never store incompatible materials
together
• Vapours will react
