  1. A solar crew chief is conducting a Job Hazard Analysis (JHA) before a roof installation. Which step comes FIRST in the JHA process?

    Answer: Break the job into basic steps

    A JHA begins by breaking the task into sequential steps before hazards can be identified and controls assigned.

  2. During a hot-work permit process for a rooftop installation requiring grinder use, which condition requires an immediate work stoppage?

    Answer: A fire watch is not posted within 35 feet of the work

    NFPA 51B and site hot-work permits require a fire watch within 35 feet of hot work; absence of a fire watch is grounds for immediate stoppage.

  3. What is the correct sequence for donning Arc Flash PPE before working on an energized PV combiner box?

    Answer: Arc-rated clothing → face shield/hood → rubber gloves with leather protectors → other PPE

    Arc-rated clothing is donned first to establish the base layer, followed by head/face protection, then rubber insulating gloves with leather protectors, then ancillary PPE.

  4. A solar installer in Arizona is working outdoors in July. OSHA's Heat Illness Prevention guidance requires a rest break in the shade when the heat index exceeds which threshold?

    Answer: 103°F

    OSHA's heat illness prevention guidance recommends mandatory rest breaks and enhanced controls when the heat index reaches 103°F (39°C) or above.

  5. Which document must be available on-site at all times during a construction phase PV installation to comply with OSHA Hazard Communication requirements?

    Answer: Safety Data Sheets (SDS) for all hazardous chemicals on site

    OSHA 29 CFR 1910.1200 (HazCom) requires SDS for all hazardous substances to be readily accessible to workers during each work shift.

  6. A module develops a hot spot during commissioning and its surface temperature reads 185°F. What is the FIRST action the technician should take?

    Answer: De-energize the string using the combiner disconnect, then assess the module

    The first step is controlled de-energization of the affected string via the combiner disconnect before physically handling or assessing the overheated module.

  7. Under NEC 690.56, what is required at a building with a PV system to enable first responders to quickly disconnect power?

    Answer: A building disconnecting means accessible from the outside or identified for emergency responder use

    NEC 690.56 requires a building disconnecting means for PV systems that is readily accessible and identified for use by emergency responders.
