#1
Which of the following is a primary hazard associated with working at heights in construction?
Falling
ExplanationFalling is a primary hazard as it poses significant risk to workers' safety when working at heights.
#2
What is the minimum height at which fall protection is required in construction?
4 feet
ExplanationFall protection is typically required at heights of 4 feet or more to mitigate the risk of serious injury or death from falls.
#3
What does the term 'PFAS' stand for in the context of fall protection?
Personal Fall Arrest System
ExplanationPFAS stands for Personal Fall Arrest System, a critical component of fall protection gear designed to minimize the risk of injuries from falls.
#4
Which of the following is NOT a component of a personal fall arrest system?
Safety glasses
ExplanationSafety glasses are not typically included in a personal fall arrest system, as they primarily protect against eye injuries rather than falls.
#5
Which of the following is an example of passive fall protection?
Guardrail system
ExplanationA guardrail system is an example of passive fall protection, providing a physical barrier to prevent falls without requiring active engagement by the worker.
#6
What is the purpose of a self-retracting lifeline in fall protection?
To arrest a fall after it occurs
ExplanationSelf-retracting lifelines are designed to arrest falls after they occur, rapidly stopping the worker's descent to minimize injury.
#7
Which type of fall protection system is typically used for leading edge work where guardrails are not feasible?
Personal fall arrest systems
ExplanationPersonal fall arrest systems are used in situations where guardrails are not practical, providing individualized protection by arresting falls.
#8
What is the maximum arresting force allowed by OSHA for a personal fall arrest system?
2200 pounds
ExplanationOSHA mandates that the maximum arresting force for personal fall arrest systems should not exceed 2200 pounds to minimize the risk of injury upon fall arrest.
#9
What is the primary purpose of a safety monitor in fall protection?
To prevent falls by monitoring workers
ExplanationSafety monitors play a crucial role in fall prevention by overseeing workers' activities and intervening to prevent falls when necessary.
#10
Which type of fall protection system relies on a system of guardrails to prevent falls?
Guardrail systems
ExplanationGuardrail systems provide passive fall protection by creating a physical barrier along edges or openings, preventing accidental falls.
#11
What is the main purpose of a fall restraint system?
To prevent a fall from occurring
ExplanationFall restraint systems are used to prevent workers from reaching areas where fall hazards exist, reducing the likelihood of falls.
#12
When inspecting fall protection equipment, which of the following should NOT be considered?
Manufacturer's warranty
ExplanationWhile important, manufacturer's warranty should not be the sole factor in assessing fall protection equipment, as other aspects like condition and compatibility are crucial.
#13
Which of the following factors affects the choice of fall protection equipment?
Type of work being performed
ExplanationThe nature of the work being undertaken influences the selection of fall protection equipment, ensuring it is appropriate for the specific tasks involved.
#14
What is the purpose of a self-retracting lifeline (SRL) in fall protection?
To arrest a fall by quickly stopping the worker's descent
ExplanationSelf-retracting lifelines are designed to rapidly arrest falls by automatically stopping the worker's descent, minimizing the risk of injury.
#15
Which of the following statements about the 'hierarchy of fall protection' is true?
Elimination of the fall hazard is the preferred method of protection.
ExplanationThe hierarchy of fall protection prioritizes eliminating fall hazards whenever possible, considering it the most effective approach to ensuring worker safety.
#16
In the context of fall protection, what does the term 'controlled access zone' refer to?
A designated area where fall protection is not required
ExplanationControlled access zones are designated areas where specific safety measures may not be required due to lower fall risks, often under close supervision.
#17
What is the purpose of a 'safety factor' in fall protection equipment?
To account for variations in worker weight and movement
ExplanationSafety factors in fall protection equipment ensure a margin of safety by accounting for potential variations in worker weight, movement, and environmental conditions, enhancing overall system reliability.
