What is the minimum number of people required for a confined space?

The minimum number of people required for a confined space is two. This requirement is primarily for safety reasons. When working in confined spaces, having at least one person designated as a safety watcher or attendant is crucial. This attendant observes the worker inside the confined space and is responsible for calling for help if needed.

The presence of a second person helps ensure that there is someone who can provide assistance or initiate an emergency response if the worker inside becomes incapacitated or requires immediate help. This practice follows safety regulations and standards aimed at reducing the risks associated with confined space entry, where hazards such as toxic atmospheres, lack of oxygen, or potential engulfment can pose serious dangers to workers.

Ultimately, having two people ensures a safer working environment and is considered a best practice in confined space operations.
