In seismic-prone areas, cables should be tightly secured to racks and cable trays to minimize movement during seismic activity. Properly securing the cables prevents them from being damaged due to excessive motion, which could lead to outages or damage to connected equipment.

Detailed Explanation:

Loose cables can be vulnerable to shaking or sudden jolts during an earthquake, increasing the risk of disconnection or damage. By tightly organizing and securing cables, you ensure they remain in place, even during significant movement, thereby maintaining connection integrity and reducing the risk of physical damage.

EPI Data Center Specialist References:

EPI training includes considerations for data centers in seismic zones, advising that cables be firmly anchored to support structures to reduce movement and mitigate potential damage during seismic events.

Fire-rated glass must be installed within manufacturer’s tested maximum exposed area. Oversized panes risk failure under fire conditions. If the window exceeds 2 m², the correct approach is to subdivide it into smaller sections, each ≤2 m², using approved fire-rated frames.

Options B and C (silicone or aluminum splits) are not certified fire-rated framing methods. Option A is unsafe because normal glass provides no fire protection.

Therefore, option D ensures compliance and safety.

In a wet pipe system, the piping is always filled with water under pressure. When a sprinkler head is triggered by heat, water is discharged immediately. This is the most common sprinkler system for general buildings.

Dry pipe: Pipes contain air or nitrogen; water enters only after valve activation.

Deluge: Pipes are empty, and all heads open simultaneously, releasing water everywhere.

Pre-action: Pipes are dry until detection and valve activation; reduces accidental discharge risk, recommended for IT rooms.

Since the definition describes immediate discharge from water-filled pipes, this is a wet pipe system.
