A-15 Refractory Bulkhead
A-15 refractory bulkhead is a type of fire-resistant partition used on marine vessels. It is designed to prevent the spread of fire between compartments for at least 15 minutes, meeting the A-15 fire rating as per the International Maritime Organization (IMO) standards.
Overview
Key features include:
1. Fire Resistance: The bulkhead can withstand exposure to high temperatures for 15 minutes before allowing heat transmission through the structure.
2. Materials: Typically made of fireproof or refractory materials, such as ceramic fibers, mineral wool, or specially treated steel panels.
3. Applications: Installed in key areas of a ship, such as engine rooms, control rooms, and living quarters, where fire safety is critical.
4. Insulation: Often combined with thermal insulation to reduce heat transfer and maintain structural integrity during a fire.
