Sources of Hazardous Materials

• Chemical plants

• Service stations

• Hospitals

• Hazardous materials waste sites

• Transport vehicles

Sensory Information

• What do you see? Hear? Smell?• Is there a vapor cloud?• Is there a fire?• Can you hear escape of a pressurized product?• Any unusual odors?• Are your eyes watering, burning?• Are there dead animals, birds, fish observable?

During a Hazardous Materials Incident

• Leave the area!

• Report the incident.

• If hearing a warning, listen for instructions.

During a Hazardous Materials Incident

• Stay away from the incident site.

• If outside, stay upstream, uphill, and upwind.

• If in a motor vehicle, stop and find shelter.

• If asked to evacuate, do so immediately.

• If requested, stay indoors—shelter in place.

If Asked to Shelter in Place

• Get household members and pets inside.

• Close and lock exterior doors and windows.

• Turn off air conditioners and ventilation systems.

• Go to the pre-selected safe room.

Post-incident Actions

• Do not return home until instructed.

• Open windows and vents and turn on fans.

• Follow decontamination procedures.

• Learn how to clean up land and property.

• Report any lingering hazards.

Household Chemical Safety

• Read directions before using.

• Store in safe, secure location.

• Avoid mixing chemical products.

• Never smoke while using chemicals.

• Clean up spills immediately.

During a Household Chemical Emergency

• If poison is consumed:– Find containers immediately.– Call poison-control center, follow instructions.

• If chemical gets into the eyes:– Follow emergency instructions on container.– Seek medical attention.

• If a fire or explosion occurs:– Evacuate residence immediately.– Move upwind to avoid breathing toxic fumes. – Call the fire department from outside.

Symptoms of Poisoning

• Difficulty breathing

• Irritation of eyes, skin, throat, or respiratory tract

• Changes in skin color

• Headaches, blurred vision, dizziness

• Clumsiness or lack of coordination

• Cramps or diarrhea

Effects of Exposure

• ACUTE - sharp or severe in effect; intense. An immediate issue like a burn.

• CHRONIC - having long had a disease, habit, weakness. Something that builds up over time or is long lasting in effect such cancer.

Definitions from Dictionary.com

Routes of Exposure

•Inhalation•Absorption •Ingestion •Injection

MSDS

Material Safety Data Sheet

• Chemical information sheets that include chemical ID, physical characteristics, hazardous ingredients, health hazards, handling precautions, first aid, reactivity data and control procedures

• Must have a sheet for every hazardous chemical on site and must be accessible to every employee – even Burger World!

DOT Hazard Diamond

Material ClassificationClass 1 - Explosive Hazards

• Explosions are very fast chemical reactions which release large quantities of gas.

• Explosives include:– sporting ammunition– blasting charges and detonators– fireworks

Material ClassificationClass 2 - Compressed Gases• A compressed gas has a physical

hazard due to the increased pressure under which the chemical is maintained.

• Compressed gases include:– oxygen– nitrogen– compressed air– acetylene

Material ClassificationClass 3 - Flammable Liquids• Flammable liquids, as the name

implies, are liquids which burn.• Flammable liquids include:

– gasoline– alcohols– solvents such as benzene

Material ClassificationClass 4 - Other Flammable

Hazards• Other flammable hazards include:

– flammable solids– self-reactive substances– substances which, in contact with water,

emit flammable gases

Material ClassificationClass 5 - Oxidizers/Organic

Peroxides• These are chemicals which will

accelerate combustion.• Examples include:

– sodium chlorate– hydrogen peroxide– methyl ethyl ketone

Material ClassificationClass 6 - Toxic & Infectious

Agents

• Health hazards include those products and materials which have an adverse effect on humans and animals.

• Examples include:– pesticides– tissue/blood samples

Material ClassificationClass 7 - Radioactive

Materials

Material ClassificationClass 8 - Corrosives

• Corrosive materials will react chemically with steel, aluminum or skin.

• Examples include:– acids such as hydrochloric– alkaline materials such as

sodium hydroxide– gases such as chlorine and

ammonia

Material ClassificationClass 9 - Miscellaneous

Hazards• Don’t readily fall into the other

categories.• Examples include:

– substances with noxious odor– substances which are magnetic– dry ice

• Personal Protective Equipment (PPE) should be provided by employer

• PPE is not an excuse for poor planning or not taking necessary cautions

• Use of PPE does not eliminate the hazard so if the equipment fails then exposure occurs

• Must be worn to provide protection• Exposure is ALWAYS a risk!
