What is the minimum number of personnel required for confined space entry under OSHA regulations?

Under OSHA regulations, the minimum number of personnel required for confined space entry is two. This requirement is in place to ensure safety during confined space operations. Having a minimum of two personnel allows for one individual to enter the confined space to perform work while the other remains outside as a monitor or attendant. This designated attendant is responsible for keeping an eye on the worker inside, maintaining communication, and being prepared to initiate rescue procedures if needed.

The presence of a second individual significantly enhances safety and communication. If an emergency occurs inside the confined space, the attendant can quickly call for help or execute a rescue, ensuring that help is available in a timely manner. Therefore, having at least two personnel helps to mitigate risks associated with confined space work, such as hazardous atmospheres or potential for entrapment.

In situations where additional hazards are identified, or where the risks are particularly high, OSHA may require more personnel to ensure safety measures are effectively implemented.
