First responders understanding of the periodic table of elements

1. You are the instructor for a group of first responders. In your own words, how would you describe the periodic table of elements in a way that can help them understand the chemical and physical characteristics of chemicals that could be part of an incident to which they have to respond?

2. Analyze the differences between ionic and covalent bonds and discuss why it is important for a responder to know the difference.

3. Explain the ionization of molecules and why it is important to responders to a hazardous materials incident.

4. There are certain trends recognized on the periodic table depending on the element’s location on the table. Categorize these different trends in relation to what is the reason for the trend on the periodic table.

Chemicals in your Household

Identify the top 8-10 chemicals in your household used for cleaning or for a hobby you might have. Differentiate these chemicals into different chemical classes to include organic and inorganic, and perform a review of the toxicological risk that they pose to you or your family. Be sure to address the following items for each chemical in your presentation:

Predict the potential chemical and physical properties and how this chemical could react with other chemicals in the household.

Describe how intermolecular forces can influence the physical properties of each chemical.

For each chemical, determine if the chemical is in a gaseous form.

Correlate the exposure to chemicals with toxicological applications (e.g., is it toxic when inhaled, does it absorb through the skin, etc.).

Toxicological effects of a chemical

Describe a time when you were concerned about the possible toxicological effects of a chemical. For example, a child digesting a dangerous chemical or pharmaceutical product, an actual chemical you worked with that touched your skin or you inhaled, etc. Why were you concerned about this chemical’s toxicology profile?

Chemicals can be toxic because they can harm us when they enter or contact the body. Exposure to a toxic substance such as gasoline can affect your health. Since drinking gasoline can cause burns, vomiting, diarrhea and, in very large amounts, drowsiness or death, it is toxic.
