CHEMICAL SAFETY
Many chemicals are used industry and day to day life, The chemicals are categorized into two major Chemical Groups, that are
Organic Chemicals
Inorganic Chemicals
All chemicals to be stored and
handled with all the safety precautions are followed as per the MSDS – Material
Safety Data Sheet.
Organic Chemicals
Aromatic Hydrocarbons
• Benzene, toluene, xylene, and
naphthalene
Halogenated Hydrocarbons
• Freon, CFC’S, and PCB’S
Phosphorylated Hydrocarbons
• Organophosphates
Oxygenated Hydrocarbons
• Aldehydes, ketones, and
carboxylic acids
Hazards of Organic Chemicals
Most are flammable
• Characteristics such as
flashpoints lower and upper flammability and autoignition temperatures should
be known
Most are anesthetics
• They should always be used in
well-ventilated spaces
Some are carcinogens
• Toxicity limits should be known
and appropriate personal protective equipment worn
Inorganic Chemicals
Acids
Bases
Salts
Hazard of Inorganic Chemicals
Corrosive
• The second most commonly used and
transported group of hazardous materials.
• “Any liquid that has a severe
corrosion rate on steel”.
Corrosive
OSHA Definition:
• “A chemical that causes visible destruction
of, or irreversible alterations in, living tissue by chemical action at the
site of contact.”
