1. Chemical Properties
Hazardous materials

2. Chemical Properties
Chemical Properties are often difficult to observe- they may only be noticeable during a reaction.
Some examples of chemical properties include:
Flammability
Ability to Oxidize (Corrosive)
Acidity or Alkalinity (pH)

3. Terminology and what it means
Flammability- the ability for something to ignite when around heat or flames.
Ability to oxidize- this is the ability for a material to corrode, the most common form is rust. (oxidation)
Alkalinity or acidity- this is how acidic or basic something is- it is measured by the pH scale. pH can indicate toxicity. (harmful if ingested)

4. Many chemicals are hazardous
Hazardous means any item (toxic, flammable or corrosive) that can cause harm to humans, animals, or the environment.
Harm can be caused through a variety of ways such as ingestion (swallowing or eating), through absorption (through the skin), inhalation (breathing it in) and through reactions.

5. Types of hazards
There are many types of hazards they include toxic, flammable and corrosive just to name a few.
There are symbols to help you figure out the hazards for many different chemicals.

6. Think time List the types of hazards you can think of.
Try to identify if they are corrosive, flammable or toxic hazards. Some may be bio- chemical hazards as well. (Such as medical waste, viruses, etc…)
