Introduction to OSHA
This module explains why OSHA exists, the rights it gives workers, the responsibilities it places on employers, and how the agency enforces safe workplaces. Understanding these basics helps you recognize when your rights are being protected and what to do when they are not.
Focus Four Hazards
The Focus Four are the leading causes of death in construction: falls, electrocution, struck-by, and caught-in/between. This module helps you recognize each hazard and the basic controls that keep workers alive.
PPE & Lifesaving Equipment
Personal protective equipment protects workers from hazards that cannot be fully removed by other controls. This module covers the main types of PPE, who provides it, and how to keep it working properly.
Health Hazards in Construction
Not all construction dangers cause immediate injury; many harm health slowly through exposure to dust, chemicals, and noise. This module covers common health hazards and how the Hazard Communication Standard helps workers understand the chemicals around them.
Electives
Elective topics cover common construction operations with their own specific hazards and rules. This module introduces cranes and rigging, scaffolds, ladders and stairways, hand and power tools, and excavations.
