What must be done before replacing a bag filter?

Before replacing a bag filter, it is crucial to complete the normal shutdown procedures and turn off the main power to ensure safety and prevent any accidental operation of the system during maintenance. Normal shutdown procedures are designed to safely depressurize the system and remove any residual flow or pressure that could cause injury. Shutting off the main power is equally important as it prevents any unexpected activation of pumps or other equipment while the maintenance work is being performed.

This comprehensive approach minimizes risks and ensures that the maintenance is performed safely, avoiding any potential hazards associated with electrical components or residual system pressure. It also aligns with best practices for maintenance, highlighting the importance of thorough preparation before beginning any repair or replacement work on system components.
