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

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

Page 10: Reactive Chemicals Training Presentation

Intentional Reactions• Exothermic and

endothermic reactions• Heat generation• Addition of heat• Losing control of the

intended reaction

Page 11: Reactive Chemicals Training Presentation

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

Peroxide Formers• React with oxygen,

may explode• Inhibitor or stabilizer

may be added• Often labeled by

another characteristic• Avoid prolonged

storage • Examples

Water Reactives• Heat, toxic gases,

ruptured containers• DOT Hazard Class 4.3• ‘W’ in NFPA label• Avoid inadvertent

contact with water• Examples

Oxidizers• Yield oxygen or

promote combustion• DOT Hazard Class 5.1• ‘OX’ in NFPA label• Avoid contact with

combustible materials• Examples

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

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?

Hazard Management Program• Active monitoring• Audits of procedures

and practices• Management of

change• Keeping abreast of

new technology• Corrective action

Page 19: Reactive Chemicals Training Presentation

PPE • Gloves• Goggles and face

shield• Chemical-resistant

clothing• Air-supplied respirator

Page 20: Reactive Chemicals Training Presentation

Investigating Incidents • Report all incidents and near misses• Investigate root causes• Identify unrecognized hazards• Identify measures to eliminate or reduce

hazards• Communicate findings

Page 21: Reactive Chemicals Training Presentation

First Aid • Skin—flush with water• Eyes—flush with water

for 15 minutes• Inhalation—move

to fresh air• Ingestion—seek

medical attention

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

Page 23: Reactive Chemicals Training Presentation

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?
