When should barriers be put up around a confined space?

Barriers should be put up around a confined space before any work begins to ensure that the area is securely isolated from unauthorized personnel and to prevent accidental entry. This is crucial for maintaining safety, as confined spaces often have unique hazards that can pose significant risks to individuals who are not trained or equipped to work in those environments.

Establishing barriers prior to starting work allows for the implementation of safety protocols that are intended to minimize the risk of accidents, injuries, and exposures to potentially dangerous conditions. It serves as a proactive measure to prepare the worksite and ensure that the environment remains controlled until all safety checks and preparations are in place. Ensuring that barriers are established early also communicates to all personnel that the area is designated as hazardous and promotes vigilance among workers who will be entering the confined space.
