Title
Unit Lesson
We studied some interesting hazardous materials in Unit III that are found not only in the workplace but also
at home. In Unit IV, we move on to study the chemistry of toxic materials. The term toxic is synonymous with
poison, identified with a skull and crossbones. Toxic materials are
covered in Chapter 10 of our textbook.
You may notice that some of the corrosive hazardous materials that
we covered so far can also be classified as toxic because some
materials can possess multiple hazardous characteristics. When
these hazardous materials are transported, both the primary and
subsidiary U.S. Department of Transportation (DOT) hazard class
or division number must be displayed, if applicable, on the lower
corner of a placard.
Toxic substances (also known as toxicants or poisons) can cause
injury, illness, or possibly death when the body is exposed to them,
even in small quantities. As such, these substances require special
attention during their manufacture, storage, transport, use, or
emergency response incidents. Toxic materials are not always
encountered in the product or waste form but could also be an
intermediate product that gets formed from the interaction of raw
materials or products. An example of a toxic substance
encountered at fire incidents is carbon monoxide (CO).
Chapter 10 focuses on some common toxic substances that could be present as an environmental health and
safety and fire science professional perform their duties. Some of these substances, which include carbon
monoxide and hydrogen sulfide, are briefly discussed below and are covered in more detail in the textbook.
Warfare agents, such as ricin, are also briefly discussed. As with the previous units, workplace regulations,
transport requirements, and recommended incident response actions are also discussed in the textbook.
