About OSHA 10-Hour Training

The OSHA 10-Hour Construction Industry Outreach Training course, delivered by an authorized OSHA trainer, is required or expected by many employers and, in some states, by law for construction workers. Per the official OSHA Construction Industry Procedures, the required curriculum includes 1 hour on Introduction to OSHA and 4 hours on the "Focus Four" hazards, the leading causes of construction worker deaths.

Why this matters: Falls alone require more mandatory training time than the other three Focus Four hazards combined, because falls are the single leading cause of death on construction sites. This practice reflects that same weighting.

Why Practice Before Your Course

Reinforcing the Focus Four material before or after your official 10-Hour course, rather than only seeing it once during class, helps the material stick, especially the specific thresholds and requirements (like fall protection at 6 feet, or trench protection at 5 feet) that come up on the job, not just on a quiz.

How to Prepare for the OSHA 10-Hour

About the real test

OSHA 10-Hour Construction training requires 1 hour on Introduction to OSHA and 4 hours on the Focus Four hazards: Falls, Electrocution, Struck-By, and Caught-In or Between. Falls alone require a minimum of 1.5 hours, more than the other three combined.

Things that make the biggest difference

Falls deserve the most study time, by design

Falls are the leading cause of death in construction, which is why the official curriculum requires more time on Falls than the other three Focus Four hazards combined.

Know the specific numbers, not just the concepts

Fall protection at 6 feet, trench protection required at 5 feet, minimum approach distances near power lines: these specific thresholds show up in real questions, not just general safety awareness.

This supplements, it doesn't replace, your official course

You still need to complete an official OSHA 10-Hour course from an authorized trainer to receive your card. This practice reinforces that material.
