Before entering a confined space, what is the essential check to perform?

The essential check before entering a confined space is to make sure to "confirm" and "verify" it is safe to enter. This process involves conducting a comprehensive assessment to ensure that the environment is free from hazardous conditions, such as toxic gases, low oxygen levels, or explosive atmospheres. This confirmation often includes reviewing safety protocols, checking atmospheric conditions, and possibly employing gas detection equipment to monitor air quality.

"Confirming" and "verifying" safety helps to protect workers from the inherent dangers of confined spaces, which can include asphyxiation, exposure to harmful substances, or the risk of entrapment. It is crucial for ensuring that all safety measures are assessed and that the workspace is safe before any entry takes place. This fundamental step is vital for maintaining health and safety standards in the workplace.

While checking for personal protective equipment, ensuring good ventilation, and notifying a supervisor are indeed important safety practices, they are typically secondary to the primary need to verify that it is safe to enter the confined space itself.
