Learners examine the ways in which a motor starter circuit is protected by a main circuit breaker and overload heaters when there is excessive current.

Learners examine devices that are used to protect a motor from damage, such as fuses, overload heaters, and thermal protectors. A quiz completes the activity.

Explore how to prevent injuries caused by falling from ladders or elevated heights by looking at the parts of a ladder, ladder safety rules, and personal fall protection systems.

Learners use the National Electrical Code to determine the size of a motor overload protection device.

In this learning activity you'll explore how a fuse de-energizes a parallel circuit when too many lamps are connected to a power outlet.

In this interactive object, learners examine problem areas related to patients with arthritic conditions. They also identify treatment precautions and design a treatment plan.

Learners read about lab equipment and basic safety measures. In a quiz, they view photos and determine if the lab technicians pictured are using safe practices.

In this simulation activity, an electrician will troubleshoot an AC motor that quit running and cannot be restarted. Before accessing blueprints and then using a multimeter to find the fault, the learner will follow safety protocols by following lock-out tag-out procedures and then suit up with appropriate (PPE) personal protection equipment.

The Animal Welfare Act, or AWA, gives protection to animals used in research, education, and entertainment. Explore ethical use and some of the current alternatives in this module.

In this simulation activity, an electrician will troubleshoot an AC motor that is overheating. Before accessing blueprints and then using a multimeter to find the fault, the learner will follow safety protocols by following lock-out tag-out procedures and then suit up with appropriate (PPE) personal protection equipment.

Explore Intrusion Detection Systems, what they are, how they're configured, and the types of protection the provide.
