OSH 3640, Interactions of Hazardous Materials 1 Course Learning Outcomes for Unit IV Upon completion of this unit, students should be able to: 1. Examine chemistry fundamentals. 1.1 Recognize the chemical and physical properties of common toxic materials. 2. Analyze chemical interactions as they relate to control of potential hazards. 2.1 Determine the chemical interactions of some common toxic materials and associated hazards. 5. Research important standards related to hazardous substances. 5.1 Describe workplace-related standards for some common toxic materials. Course/Unit Learning Outcomes Learning Activity 1.1 Unit Lesson Chapter 10, pp. 366–440 Unit IV Assessment 2.1 Unit Lesson Chapter 10, pp. 366–440 Unit IV Assessment 5.1 Unit Lesson Chapter 10, pp. 366–440 Unit IV Assessment Required Unit Resources Chapter 10: Chemistry of Some Toxic Substances, pp. 366–440 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 toxicis 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 UNIT IV STUDY GUIDE Chemistry of Toxic Substances Black and white skull and cross bones (Close, n.d.)
OSH 3640, Interactions of Hazardous Materials 2 UNIT x STUDY GUIDE Title 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.
