• You will learn about:
– The Hazards of chemicals.
– Our written program.
– How chemicals are labeled.
– Safe use of chemicals.
– Material Safety Data Sheets
– Basic procedures for spills.
– Who you can ask for more information.
SafetyonCall
HAZARDS OF CHEMICALS
• There are 2 basic types of chemical hazards:
1. Physical Hazards
2. Health Hazards
• The first rule of Chemical safety is… "Know what you are
working with and how to protect yourself and others.“
SafetyonCall
PHYSICAL HAZARDS
•
Chemicals are classified as having Physical Hazards if they are:
– Explosive
– Compressed Gas
– Combustible Liquids
– Flammable
– Unstable
– Water Reactive
– Oxidizers
SafetyonCall
PHYSICAL HAZARDS
• Some chemicals may be safe by themselves, but become
dangerous when in contact with other substances.
SafetyonCall
CHEMICALS WITH PHYSICAL HAZARDS
• Used only by trained employees.
• Stored in a safe manner.
• Never mixed with other chemicals unless by an approved
procedure.
SafetyonCall
HEALTH HAZARDS
• Chemicals are classified as being a health hazard if they:
– Can cause cancer.
– Are poisonous (toxic).
– Cause harm to your skin, internal organs, or nervous
system.
– Are corrosive - such as acids.
– Cause allergic reactions after repeated exposure.
SafetyonCall
WAYS CHEMICALS CAN ENTER THE BODY
• Your lungs if you breath fumes, mists or dust.
• Your skin if liquid or dust touches or spills on you or splashes
in your eyes.
• Your mouth if you eat after handling chemicals.
• Accidental swallowing of a chemical.
SafetyonCall
HEALTH EFFECTS
• Some chemicals affect specific organs such as your kidneys,
liver, reproductive or nervous system.
SafetyonCall
OUR WRITTEN HAZARD COMMUNICATION
PROGRAM PROVIDES
• Written information on hazards.
• Lists Chemicals we use and their hazards.
• System for ensuring chemicals are labeled.
• Means to ensure we have an Material Safety Data Sheet (MSDS)
for each chemical.
SafetyonCall
OUR WRITTEN HAZARD COMMUNICATION
PROGRAM
• Lists who is responsible for the program.
• Provides chemical specific safety training methods.
• Tells you where to find chemical safety information.
• You can see a copy of our written program by asking you
supervisor.
SafetyonCall
LABELING OF CHEMICALS
• Chemical Labels provide information on Identity, Hazards and
Safe Use.
• All chemical containers are labeled by the manufacturer.
• Our company may place additional labels on the containers.
SafetyonCall
LABELING OF CHEMICALS
• If chemicals are placed in another container, this new
container must have a label placed on it.
• All containers must be properly labeled.
SafetyonCall
UNIFORM LABELING SYSTEM
• Our Company “Uniform Labels” are used to ensure we have
one labeling system.
• These may be placed on containers when chemicals are
delivered to us or chemicals are transferred to other
containers.
SafetyonCall
2 BASIC “UNIFORM LABELS”
• HMIS - Hazardous Material Identification System
• NFPA - National Fire protection Association
Both types must identify the chemical name and hazards
SafetyonCall
UNIFORM LABELS
• Pictures may be used to identify hazards and required
protection.
• This Information may also be on the Manufacturer’s label.
SafetyonCall
HMIS & NFPA LABELS ARE VERY SIMILAR
• Both use colored boxes to identify specific hazards.
• Numbers or codes in the boxes tell you the hazard value higher number = higher hazard.
SafetyonCall
NFPA & HMIS LABEL COLORS
• Red - Fire Hazard
• Blue - Health Hazard
• Yellow - Reactivity Hazard - explosive, unstable
• White - Special Hazards - corrosive, radioactive, water
reactive, acid
SafetyonCall
NFPA LABEL
• The purpose of the NFPA 704 labeling system is to provide a
way of quickly identifying the various fire related hazardous
associated with a particular material. The NFPA 704 "diamond"
is commonly found on bulk storage containers, but is also
widely used on chemical containers and MSDS sheets.
SafetyonCall
