OSHA 10-Hour Construction Review Activity (15 Minutes)

Topic: OSHA Focus Four Hazards
Audience: High School Construction Students
Objective: Review the four leading causes of construction injuries and fatalities before taking the OSHA 10-Hour Construction course assessment.

Activity Overview (15 Minutes)
1. Quick Review Warm-Up (3 Minutes)

Ask students to work with a partner and list the OSHA Focus Four hazards from memory.

Focus Four Hazards:

Falls
Struck-By
Caught-In/Between
Electrocution

Briefly remind students:

Falls = working at heights
Struck-By = hit by moving or falling objects
Caught-In/Between = crushed, squeezed, or pinched
Electrocution = contact with electrical energy
2. OSHA Focus Four Quiz (7 Minutes)

Have students answer individually, then review together.

Question 1

Which OSHA Focus Four hazard is the leading cause of death in construction?

Answer: Falls

Question 2

A worker is standing beneath a suspended load and is hit when materials fall from a crane. What hazard category is this?

Answer: Struck-By

Question 3

What is the minimum protection generally required when employees work on unprotected sides or edges 6 feet or more above a lower level?

Answer: Fall protection (guardrails, safety nets, or personal fall arrest systems)

Question 4

A trench collapses and traps a worker. Which Focus Four hazard does this represent?

Answer: Caught-In/Between

Question 5

Name one method used to prevent electrocution on a construction site.

Answer: Any of the following:

Use GFCIs
Inspect cords before use
Maintain safe distances from power lines
Lockout/Tagout procedures
Use properly grounded equipment
Question 6

A backing dump truck strikes a worker walking behind it. Which hazard category applies?

Answer: Struck-By

Question 7

What should workers do before entering a trench deeper than 5 feet?

Answer: Ensure a protective system is in place (sloping, shoring, or shielding/trench box) unless the excavation is made entirely in stable rock.

Question 8

True or False: Rubber-soled shoes alone provide adequate protection from electrical hazards.

Answer: False

3. Group Scenario Challenge (5 Minutes)
Scenario:

A construction crew is installing roofing materials on a two-story building. One worker is near the roof edge without a harness. A forklift is moving materials below the roof. An extension cord with damaged insulation is powering a saw, and workers are unloading materials next to a narrow trench.

Group Task:

Identify as many Focus Four hazards as possible and suggest one control method for each.

Sample Answers
Hazard Example in Scenario Control MethodFalls Worker near roof edge Use guardrails or personal fall arrest system
Struck-By Forklift transporting materials Establish exclusion zones and maintain awareness
Electrocution Damaged extension cord Remove damaged cord and replace it
Caught-In/Between Working beside trench Use trench protection and keep materials away from edge
Wrap-Up Discussion

Ask students:

"If you could prevent only one of the Focus Four hazards on a jobsite, which would save the most lives and why?"

Expected discussion: Falls are typically the leading cause of fatalities, but all Focus Four hazards require prevention because each can be deadly.

Key Reminder: The OSHA Focus Four hazards account for the majority of serious injuries and deaths in construction. Recognizing hazards before work begins is one of the most effective ways to stay safe on the jobsite.

Auto diagnostic walkthrough 4.6/5

Why: Logical simple-to-involved order (scan and freeze frame, visual, fluids, fuel trims, plugs, coil swap, smoke test, fuel pressure, injectors, compression, leak-down) with tools and what each result means, and it flags a flashing MIL as catalyst-damaging. It doesn't warn to relieve fuel pressure or mention GDI high-pressure fuel before connecting a gauge, skips TSBs, and the 5 reflection questions have no answers.

Prompt

Write a step-by-step diagnostic walkthrough for high school automotive students: a 2012-2018 gasoline car comes in with a check engine light and code P0300 (random/multiple cylinder misfire). Show the logical order of tests from simplest to most involved, what tools are needed, what each result means, and safety notes. Format it as a student handout.

Always:

✅ Wash hands thoroughly with soap and water before handling safe foods.

✅ Clean and sanitize work surfaces, cutting boards, utensils, and equipment before use.

✅ Use separate utensils, containers, and cutting boards when preparing allergen-free foods.

✅ Read ingredient labels every time a product is used.

✅ Store allergen-containing ingredients in clearly labeled containers.

✅ Prepare allergen-free meals first whenever possible.

✅ Change gloves after touching allergen-containing foods.

✅ Inform the instructor immediately if ingredient information is unclear.

Never:

❌ Assume a food is safe because it was safe before.

❌ Use the same knife, spoon, spatula, or cutting board without washing and sanitizing.

❌ Reuse marinades, sauces, or frying oil for allergen-free foods.

❌ Remove an allergen from a finished dish and assume it is safe.

❌ Taste food with a utensil and return it to the product.

Emergency Awareness
