Electrical Installations in Hazardous Areas Video Based Training - (LGC TV)Mr. Scott Mercurio

Electrical Installations in Hazardous Areas Training is intended for, and published for, the Marine Inspector. We currently have short lectures available and will develop technical training episodes as we move forward.

Take a moment and scan though this linked document, written by Bill Rankin - Electrical Engineer / Senior Electrical Inspector, to learn about the Typical Faults, Section 11, you may find during your inspection:

Electrical Equipment in Hazardous Areas: Field Inspections

Hazardous Area Electrical Installations have been, and continue to be, a common deficiency found aboard foreign gas carriers and domestic low flashpoint fueled vessels. The Liquefied Gas Carrier National Center of Expertise created this special channel on LGCTV specifically for Hazardous Area Electrical Installations to increase Marine Inspector knowledge of equipment installation, maintenance, and administrative requirements. Increased Marine Inspector knowledge will assist Ship Builders, Owners, Operators and Crew with understanding the importance of Hazardous Area Electrical Installations; and ultimately help save time and money, all while increasing safety.
