Question 41Construction Focus Four (Construction industry curriculum)

Under OSHA's construction standards, at what minimum height must employees be protected from falls by guardrail systems, safety net systems, or personal fall arrest systems?

  1. 10 feet
  2. 15 feet
  3. 6 feet Correct answer.
  4. 4 feet

Explanation

The construction fall protection standard (29 CFR 1926.501) generally requires fall protection at 6 feet above a lower level, though specific activities such as scaffolds and certain equipment have different trigger heights.

Question 42Construction Focus Four (Construction industry curriculum)

A worker is using a personal fall arrest system on a construction site. What is the maximum allowable free fall distance before the system must arrest the fall?

  1. 10 feet
  2. 4 feet
  3. 2 feet
  4. 6 feet Correct answer.

Explanation

OSHA limits free fall to 6 feet for personal fall arrest systems (or the system must be designed to prevent any free fall). Limiting free fall reduces the arresting forces on the body.

Question 43Construction Focus Four (Construction industry curriculum)

Which of the following best describes the purpose of a guardrail system's toeboard on an elevated work platform?

  1. To anchor personal fall arrest lanyards
  2. To support the midrail at the proper spacing
  3. To prevent tools and materials from being kicked off the edge Correct answer.
  4. To provide a handhold for workers climbing onto the platform

Explanation

Toeboards are edge barriers that keep objects from falling off elevated surfaces and striking workers below. They are part of the falling object protection required along with guardrails.

Question 44Construction Focus Four (Construction industry curriculum)

An excavation on a construction site is 7 feet deep. What does OSHA require regarding protection from cave-ins for employees working inside?

  1. Only a warning line around the edge is required
  2. No protection is required because the depth is under 10 feet
  3. Protection is required only if the soil is classified as Type A
  4. Protective systems such as sloping, shoring, or shielding must be provided Correct answer.

Explanation

Excavations 5 feet or deeper generally require a protective system unless the competent person determines there is no indication of potential cave-in. At 7 feet, a protective system is expected.

Question 45Construction Focus Four (Construction industry curriculum)

What is the primary hazard associated with working in a confined space that lacks adequate ventilation on a construction site?

  1. Poor lighting conditions
  2. Excessive noise levels
  3. Slip and trip hazards
  4. Atmospheric hazards such as oxygen deficiency or toxic gases Correct answer.

Explanation

Confined spaces can accumulate toxic or flammable gases and become oxygen-deficient without ventilation. Atmospheric testing and ventilation are core controls for these spaces.

Question 46Construction Focus Four (Construction industry curriculum)

Which practice most directly reduces the risk of electrocution when using portable electric tools on a construction site?

  1. Using tools with damaged cord insulation
  2. Working on wet surfaces without protective equipment
  3. Using tools equipped with ground-fault circuit interrupter protection Correct answer.
  4. Bypassing the grounding pin on a plug

Explanation

GFCI protection rapidly de-energizes a circuit when a ground fault is detected, reducing the chance of electrocution. OSHA requires assured equipment grounding conductor programs or GFCI protection for temporary power.

Question 47Construction Focus Four (Construction industry curriculum)

A crane is operating near overhead power lines on a construction site. What is the safest approach to prevent electrocution?

  1. Maintain the required minimum clearance and use a spotter or de-energize the lines Correct answer.
  2. Ground the crane to the power line
  3. Operate quickly to minimize time near the lines
  4. Have a worker hold the crane load steady near the lines

Explanation

The primary control is to maintain the required clearance distance from energized lines, and where that is not feasible, to de-energize and ground the lines or use other protective measures. A spotter helps the operator maintain clearance.

Question 48Construction Focus Four (Construction industry curriculum)

Which of the following is a required element of a lockout/tagout procedure for controlling hazardous energy during construction equipment servicing?

  1. Notifying affected employees and applying locks to energy-isolating devices Correct answer.
  2. Relying on verbal warnings only
  3. Allowing equipment to coast to a stop without isolating energy
  4. Removing lockout devices before servicing begins

Explanation

Lockout/tagout requires isolating energy sources, applying locks and tags, releasing stored energy, and notifying affected employees. These steps prevent unexpected energization during servicing.

Question 49Construction Focus Four (Construction industry curriculum)

What is the leading cause of fatalities in the construction industry according to OSHA's Focus Four framework?

  1. Electrocutions
  2. Struck-by incidents
  3. Caught-in or between incidents
  4. Falls Correct answer.

Explanation

Falls consistently account for the largest share of construction fatalities, which is why fall protection is a central focus of the Focus Four training. The other three categories are struck-by, electrocution, and caught-in/between.

Question 50Construction Focus Four (Construction industry curriculum)

A worker is struck by a falling brick from scaffolding above. This incident is best classified as which Focus Four hazard category?

  1. Fall
  2. Caught-in or between
  3. Electrocution
  4. Struck-by Correct answer.

Explanation

A struck-by hazard occurs when a worker is hit by a falling, flying, or swinging object. Falling objects from overhead work are a classic struck-by hazard.
