General Contractor License Construction Safety and OSHA 5 — Questions and Answers
Question 1: What action is required when a worker discovers an unguarded floor opening or hole on a construction site?
- Mark it with spray paint and continue working
- Immediately cover or guard it and warn others (Correct answer)
- Report it at the end of the shift
- Install temporary lighting around it
Correct answer: Immediately cover or guard it and warn others
Floor holes and openings must be immediately covered or guarded to prevent fall hazards under OSHA's fall protection standards.
Question 2: What is the required angle (slope) for a ladder to be safely positioned under OSHA standards?
- 1:3 (one unit out for every 3 units up)
- 1:4 (one unit out for every 4 units up) (Correct answer)
- 1:5 (one unit out for every 5 units up)
- 1:2 (one unit out for every 2 units up)
Correct answer: 1:4 (one unit out for every 4 units up)
OSHA requires portable ladders to be positioned at a 1:4 ratio — one foot out from the base for every four feet of height.
Question 3: What is the purpose of a 'toolbox talk' (also called a tailgate meeting) in construction safety?
- To review daily production quotas with workers
- To provide brief, job-specific safety training before work begins (Correct answer)
- To document equipment inspections for OSHA records
- To assign personal protective equipment to new workers
Correct answer: To provide brief, job-specific safety training before work begins
Toolbox talks are short, informal safety meetings held before work begins to address specific hazards workers will encounter that day.
Question 4: Under OSHA, which type of respirator provides the highest level of respiratory protection?
- Half-face air-purifying respirator
- Full-face air-purifying respirator
- Powered air-purifying respirator (PAPR)
- Self-contained breathing apparatus (SCBA) (Correct answer)
Correct answer: Self-contained breathing apparatus (SCBA)
SCBA provides the highest protection level because it supplies breathable air from a portable tank, independent of the surrounding atmosphere.
Question 5: How must compressed gas cylinders be stored on a construction site to comply with OSHA regulations?
- Laying flat to prevent tipping
- Upright and secured with chains or straps away from heat sources (Correct answer)
- Upright without restraints in a ventilated area
- Horizontally in locked storage containers
Correct answer: Upright and secured with chains or straps away from heat sources
OSHA requires compressed gas cylinders to be stored upright, secured with chains or straps, and away from heat sources to prevent rupture or explosion.
Question 6: When must an OSHA 300A Summary of Work-Related Injuries and Illnesses be posted in the workplace?
- January 1 through March 31
- February 1 through April 30 (Correct answer)
- March 1 through May 31
- Year-round in a visible location
Correct answer: February 1 through April 30
The OSHA 300A Summary must be posted from February 1 through April 30 of the year following the recorded injuries and illnesses.
Question 7: What is the maximum load per square foot allowed on a scaffold platform before it is considered overloaded under OSHA standards?
- The scaffold must support 2 times the intended load
- The scaffold must support 4 times the maximum intended load (Correct answer)
- The scaffold must support 5 times the intended load without failure
- The scaffold must support 3 times the maximum intended load
Correct answer: The scaffold must support 4 times the maximum intended load
OSHA requires scaffolds to be capable of supporting at least 4 times the maximum intended load without failure.
