HV Exit Exam • Set 2 Question 14 of 30

What safety floor matting must be placed in front of marine High Voltage switchboards?

✓

Direct Answer

Option D: Tested dielectric insulating rubber matting (rated for operating voltage, e.g. 15 kV - 30 kV rating)

Dielectric insulating rubber matting is a mandatory safety requirement in front of HV switchboards to protect personnel from step and touch potential hazards. These mats must be tested and rated for the specific system voltage to ensure they provide adequate electrical resistance, as specified in marine safety management and electrical installation standards.

All Options

Aluminum plate

Steel mesh mat

Wet cloth rag

Tested dielectric insulating rubber matting (rated for operating voltage, e.g. 15 kV - 30 kV rating) (Correct Answer)

Detailed Explanation & Context

Relevant Framework: STCW 2010 Manila Amendments • DG Shipping E-Learning & Exit Exam Standards • High Voltage Safety Officer & Switchgear Operations (HV).
