Q11What personal protective equipment (PPE) is required when performing a voltage test on an energized PV array?
✓ Correct answer: B. Voltage-rated gloves, safety glasses, arc-rated clothing, and insulated tools
When testing voltage on energized PV arrays, workers need proper electrical PPE including voltage-rated gloves, safety glasses, arc-rated clothing, and insulated tools to protect against electrical shock and potential arc flash incidents.
Q12Which of the following is a required element of an emergency action plan for a PV installation site?
✓ Correct answer: A. Evacuation procedures
An emergency action plan must include evacuation procedures so that all workers know how to safely exit the worksite in case of an emergency, such as fire, severe weather, or other hazardous situations.
Q13What is the proper safety procedure when a worker discovers damaged PV modules with exposed wiring on site?
✓ Correct answer: D. Stop work, cordon off the area, and report the hazard to a supervisor
The proper procedure is to immediately stop work, cordon off the area to prevent access, and report the hazard to a supervisor. This prevents potential electrical shock hazards while ensuring the situation is properly addressed by qualified personnel.
Q14What is the main purpose of holding a daily safety briefing before starting PV installation work?
✓ Correct answer: C. To identify and communicate site-specific hazards for that day's work
Daily safety briefings help identify and communicate site-specific hazards, ensuring all workers are aware of risks and safety protocols for that day's tasks. This proactive approach helps prevent accidents and ensures everyone is prepared for the day's specific challenges.
Q15According to OSHA requirements, how often should portable ladders used in PV installations be inspected?
✓ Correct answer: B. Before each use
OSHA requires that portable ladders be inspected before each use to identify any defects or damage that could lead to falls or other injuries. This frequent inspection helps ensure that ladders remain in safe working condition.
Q16What is the proper safety measure when installing PV panels during high wind conditions?
✓ Correct answer: A. Suspend work until wind conditions improve
High winds create significant hazards for PV installation work, including the risk of panels acting as sails and workers being blown off balance. The safest response is to suspend work until wind conditions improve to prevent accidents.
Q17Which of the following is a proper control measure for heat stress when installing rooftop PV systems in hot weather?
✓ Correct answer: D. Scheduling frequent rest breaks in shaded areas and ensuring adequate hydration
Scheduling frequent rest breaks in shaded areas, along with ensuring adequate hydration, are essential measures to prevent heat-related illnesses such as heat exhaustion and heat stroke during hot weather PV installations.
Q18What safety equipment is required when cutting conduit for a PV installation?
✓ Correct answer: C. Safety glasses, gloves, and dust mask
When cutting conduit, safety glasses protect eyes from flying debris, gloves protect hands from sharp edges, and a dust mask prevents inhalation of harmful particles, providing comprehensive protection from the hazards associated with conduit cutting.
Q19What is the most appropriate first aid response for a worker who has received an electrical shock from a PV system?
✓ Correct answer: B. Call emergency services immediately and keep the victim still
The most appropriate first response is to call emergency services immediately while keeping the victim still. Moving a shock victim can worsen injuries, and prompt medical attention is essential even if the victim appears to recover quickly.
Q20Which of the following represents the correct hierarchy of hazard controls, from most to least effective?
✓ Correct answer: A. Elimination, substitution, engineering controls, administrative controls, PPE
The hierarchy of hazard controls ranks methods from most effective to least effective: elimination (removing the hazard), substitution (replacing the hazard), engineering controls (isolating people from the hazard), administrative controls (changing work practices), and PPE (protecting the worker with equipment).
