Unconnected cylinders shall be stored in an approved storage area, preferably indoors but not near a building entrance. (A) False (B) True Chose the best option according to API 1169

The statement has three main parts:

• "Unconnected cylinders shall be stored in an approved storage area" - This is a fundamental safety requirement for any hazardous material, including gas cylinders.
• "preferably indoors" - Storing cylinders indoors can protect them from weather and theft, and is often a preferred method, though outdoor storage with proper protection is also acceptable.
• "but not near a building entrance" - This is a critical safety rule. Storing cylinders near entrances could obstruct emergency exits, pose a hazard to personnel entering or exiting, and increase risk in case of a leak or fire. OSHA standards, which API 1169 inspectors would be familiar with, require cylinders to be stored away from passageways and exits.

API 1169 emphasizes safety and compliance with applicable regulations (like OSHA) on pipeline construction sites. The principles outlined in the statement align with standard industry safety practices for storing compressed gas cylinders. The requirement to store cylinders in an approved area and away from building entrances is a key safety measure to prevent accidents and ensure clear egress paths. The preference for indoor storage is a common recommendation for protection.

Since all parts of the statement reflect sound safety practices and regulatory compliance expected on a pipeline construction project, the statement is considered true in the context of API 1169.

The correct answer is B.
$\boxed{\text{B}}$
