Objectives: As you learn the skills and tasks needed to perform your job, you may not think much about safety. However, thorough knowledge of safe practices is an important part of working in any industrial setting. Every industrial worker (no matter what job he or she does) should be familiar with accident prevention techniques, fire safety methods, and the use of personal protective equipment. Injuries in the workplace cost millions of dollars in medical costs, lost wages, and productivity losses each year. More importantly to you, severe workplace injuries can be life-altering events. Many injuries can be prevented by understanding how accidents and injuries can occur. This lesson is designed to help you understand why safety in the workplace is so important, and to present you with some information about safety that goes beyond the common sense you already have.

Objectives: Chemicals and chemistry have greatly changed our lifestyles. Almost every manmade substance we see, touch, taste, or smell has some connection to chemistry. This lesson deals with the safe use of chemicals in the workplace. The two primary causes of chemical accidents are their misuse and the improper storage and disposal of chemicals and chemical wastes. Understanding the hazards that chemicals can create is the first step in protecting yourself and those around you from harm. The main goal of this lesson is to provide you with sound, practical knowledge about chemical use, storage, and disposal. You’ll learn how to recognize common chemical hazards and how to deal with them. You’ll learn how to perform a job analysis while looking for potential chemical dangers in your daily tasks. Finally, you’ll learn how to take precautions to avoid chemical accidents and make your job as safe as possible.

Objectives: This lesson introduces the information you need to practice fire safety and prevention in the workplace. While fires are the most destructive and expensive of all accidents, they can also be effectively prevented through the combined use of technology and common sense. By understanding how fires get started and how to extinguish them, you’ll have much of the knowledge you need to protect yourself from the dangers of fire.

Objectives: This lesson introduces safe work practices commonly used when handling manufacturing and industrial materials. You’ll learn the procedures necessary to avoid physical injury to yourself and those working with you, for both manual and mechanical handling methods. You’ll also learn procedures that minimize damage to the materials you’re moving as well as to facility property. Knowing the proper procedures will also give you the insight to decide when mechanical handling is necessary, or perhaps preferred, over traditional physical handling.

Course Prerequisites: Basic Industrial Math (Block X31) Practical Measurements (Block X32) Trades Safety: Getting Started (186001) What Students Learn: Pneumatic tools are used in many areas of maintenance, construction, and production work. These tools harness the power of compressed air and convert this power to useful work. Compressed air can be a very powerful energy source. However, due to this power, you must be extremely careful when using these tools. Pneumatic tools are normally made much heavier than standard-duty hand and power tools. You will notice this fact as soon as you lift an impact wrench or framing nailer. The cases of the tools are made intentionally heavy to contain the stresses of the impact hammers or piston and to absorb the normal day-to-day abuse that the tool takes. You have probably seen someone remove a tire's lug nuts with a pneumatic impact wrench. The operator picks up the wrench and blasts off four or five bolts. Next, the wrench is dropped the six inches or so to the floor while the operator's hands move to quickly grab the wheel and rim. Come back to this same shop a year later, and you will probably see the same wrench being used after thousands of tires have come and gone. The tool's case may be nicked and grooved, but if properly cleaned and lubricated, the tool could last for many thousand more tires. This text discusses the selection, use and safe practices of using different types of pneumatic tools. Objectives When a student completes this study unit, he and she will be able to: • Describe the various pneumatic tools used for plant maintenance. • Identify and describe the safe use of impact, cutting, and grinding tools. • Explain how pneumatic hammers, nailers, and staplers are selected and used in a safe manner. • Describe the use of pneumatic assembly tools such as grinders, sanders, screwdrivers, and drills and how other types of production tools are selected and used. • Identify the proper procedures for pneumatic tool and system care. • Identify safe tool use procedures and how vibration and excess noise can cause bodily injury.

Course Description: The International Plumbing Code (IPC) is used as the authoritative code in most of the United States. As you start your plumbing career, you’ll follow your supervisor’s interpretation of the code and their subsequent directions. However, your understanding of the IPC should begin even when you’re a novice in the field. As a plumbing professional, it’s essential to grasp the purpose, organization, and language of the IPC. In the field, employers and supervisors seek workers who prioritize developing their trade skills, and this includes following codes. You’ll examine codes for fixtures, equipment, and designs, and you’ll navigate the IPC to research questions and prepare for installations. 286M08 Lessons: • 151071 Studying Your Codebook • 151072 Fixtures, Heaters, and Design • 151073 Codes for Waste Removal • 151074 Special Piping Considerations • 151075 Using the Appendices
