Exercise: Identifying Box Connections

Instructions: Imagine you are working on an oil and gas platform. You are tasked with inspecting the connections on a newly installed piece of equipment.

Scenario: The equipment is a pump that will be used to transfer crude oil from a storage tank to a processing facility. The pump has several connections for incoming and outgoing pipes.

Task: 1. Identify the box connections on the pump. 2. Explain why it is important to correctly identify these connections. 3. Describe at least one safety hazard that could occur if a box connection is not properly installed.
