Disconnecting energy sources

Installing ventilation systems

Disconnecting or capping lines

The term "blanking" in confined space procedures specifically refers to the process of disconnecting or capping lines that can contain hazardous materials such as fluids or gases. This is a crucial safety measure designed to prevent the accidental release of these materials into the confined space, which could pose significant risks to personnel entering the area.

By capping or disconnecting lines, workers ensure that no contaminants can leak or flow into the confined space while work is being performed. This further reinforces the overall safety strategy by minimizing the potential for exposure to harmful substances, thus protecting the health and safety of all workers involved in the task. Effective blanking is part of a comprehensive lockout/tagout program that aims to control hazardous energy sources and create a safe working environment in confined spaces.
