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

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!

Class 1: Explosives Class 2: Gases Class 3: Flammable Liquids Class 4: Flammable Solids Class 5: Oxidizing Substances Class 6: Poisons Class 7: Radioactive Class 8: Corrosive Class 9: Miscellaneous DOT Hazard Diamond
Material Classification Class 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 Classification Class 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 Classification Class 3 - Flammable Liquids Flammable liquids, as the name implies, are liquids which burn. Flammable liquids include: –gasoline –alcohols –solvents such as benzene
Material Classification Class 4 - Other Flammable Hazards Other flammable hazards include: –flammable solids –self-reactive substances –substances which, in contact with water, emit flammable gases
Material Classification Class 5 - Oxidizers/Organic Peroxides These are chemicals which will accelerate combustion. Examples include: –sodium chlorate –hydrogen peroxide –methyl ethyl ketone
Material Classification Class 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 Classification Class 7 - Radioactive Materials
Material Classification Class 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 Classification Class 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!
