What Is a Reactive Chemical?• Solid or liquid• Reactive to air, water,
or other chemicals• Sensitive to shock,
heat, or friction• Corrosive, poisonous,
or flammable by-products

Health Hazards• Burn skin, eyes,
nose, throat• May be poisonous• Irritate eyes, skin,
and respiratory tract• Cause dizziness
and vomiting• Cause asphyxiation and
death• Consult the MSDS
for health hazard information

Fire Hazard• Friction• Absorption of moisture• Spontaneous chemical
changes• Retained heat• Readily ignited
© Business & Legal Reports, Inc. 0706
Factors That Create Reactivity Hazards• Intentional chemistry• Physical processing• Hazardous substance
storage• Processes that involve
combustion• Heat generating
processes

Factors That Create Reactivity Hazards (cont.)
The presence of:• Spontaneously
combustible chemicals• Peroxide-forming
chemicals• Water-reactive
chemicals• Oxidizing chemicals• Self-reactive chemicals• Materials that are
incompatible

Detecting Hazards • Sight• Smell• Air monitoring
© Business & Legal Reports, Inc. 0706
Intentional Reactions• Exothermic and
endothermic reactions• Heat generation• Addition of heat• Losing control of the
intended reaction
© Business & Legal Reports, Inc. 0706
Spontaneously Combustible Substances• React with oxygen to
ignite or burn without ignition• DOT Hazard Class 4.2• ‘4’ in red part of NFPA
diamond label• Avoid exposure to air• Examples
© Business & Legal Reports, Inc. 0706
Peroxide Formers• React with oxygen,
may explode• Inhibitor or stabilizer
may be added• Often labeled by
another characteristic• Avoid prolonged
storage • Examples
© Business & Legal Reports, Inc. 0706
Water Reactives• Heat, toxic gases,
ruptured containers• DOT Hazard Class 4.3• ‘W’ in NFPA label• Avoid inadvertent
contact with water• Examples
© Business & Legal Reports, Inc. 0706
Oxidizers• Yield oxygen or
promote combustion• DOT Hazard Class 5.1• ‘OX’ in NFPA label• Avoid contact with
combustible materials• Examples
© Business & Legal Reports, Inc. 0706
Self-Reactive Materials• Polymerizing, decomposing, rearranging• DOT Hazard Class 1
or 5.2• ‘1’ to ‘4’ in yellow part of NFPA label• Avoid shock, friction, heat
© Business & Legal Reports, Inc. 0706
Incompatible Materials• Results of uncontrolled reactions• Potential mixing scenarios• Consult a chemical compatibility chart• Examples
© Business & Legal Reports, Inc. 0706
Reactivity HazardsDo you understand:• What a reactive
chemical is? • The health and fire
hazards? • Factors that could
cause chemical reactivity hazards in the workplace and the form those reactions could take?
© Business & Legal Reports, Inc. 0706
Hazard Management Program• Active monitoring• Audits of procedures
and practices• Management of
change• Keeping abreast of
new technology• Corrective action
© Business & Legal Reports, Inc. 0706
PPE • Gloves• Goggles and face
shield• Chemical-resistant
clothing• Air-supplied respirator
© Business & Legal Reports, Inc. 0706
Investigating Incidents • Report all incidents and near misses• Investigate root causes• Identify unrecognized hazards• Identify measures to eliminate or reduce
hazards• Communicate findings
© Business & Legal Reports, Inc. 0706
First Aid • Skin—flush with water• Eyes—flush with water
for 15 minutes• Inhalation—move
to fresh air• Ingestion—seek
medical attention
© Business & Legal Reports, Inc. 0706
Emergency Procedures • Leave the area• Notify others• Limit access to area• Don’t return until it’s
safe• Don’t try to clean up
large spills unless authorized
© Business & Legal Reports, Inc. 0706
Emergency Equipment • First-aid kit• Spill response supplies• Safety showers• Eyewash stations• Fire extinguishers
© Business & Legal Reports, Inc. 0706
Hazard ManagementDo you understand: • All information that has
been presented in the previous slides? • All the precautions we
must take to effectively manage chemical reactivity risks and prevent accidents?
© Business & Legal Reports, Inc. 0706
Key Points to Remember• Know the hazards of reactive chemicals• Be able to identify different types of reactive
chemicals in the workplace•Wear appropriate PPE• Follow safe handling and storage
procedures• Learn emergency procedures
