  13. Compressed Gas • Compressed gas is a gas that is in a cylinder that is under a lot of pressure. • A compressed gas cylinder can become like a rocket if the cylinder is damaged or, if the gasexpands due to change in temperature. • Common materialsHeliumPropaneOxygen

  14. Flammable and Combustible Material These materials can easily catch fire. It is very important to keep these materials away from open flames. Common materials: Diesel fuel, gasoline, kerosine

  15. Oxidizing Material • Materials that react and decompose with exposure to oxygen. • Can intensify fires and explosions. • Material could combust. • Common types:ozonenitric acidperoxide

  16. Corrosive Material • Material that can attack metals • Material that can burn and destroyhuman tissues. • Common materialsSulfuric acidAmmoniaHydrochloric Acid

  17. Poisonous • This symbol means very toxic and causes immediate and serious problems if ingested,inhaled or if it comes in contact with skin. • Common materials:Carbon monoxide (gas)Hydrogen sulfide

  18. Poisonous • This sign indicates the material is poisonousand toxic that will cause less immediate effects. The effects may not be immediatebut can still be very serious. • Common materials:leadcadmiummercury

  19. Biohazardous • Organisms or toxins that can cause infection in animals or people. • Common Materials:BacteriaParasitesViruses

  20. Dangerously Reactive • Some materials react aggressively with others. • These types of materials often create uncontrolled reactions and the outcome is uncertain.
