What is a critical factor for entering any confined space?

Pairing with another worker trained in confined spaces is essential because it enhances safety by ensuring that there is someone who can respond if an emergency occurs. Confined spaces often present a range of hazards, including limited access for rescue, dangerous atmospheres, and the potential for physical entrapment. Having a second individual who is also trained increases the likelihood of recognizing hazards, implementing safety protocols, and providing immediate assistance if needed. This collaborative approach allows for better communication, shared responsibilities, and improved overall safety in potentially life-threatening environments, establishing it as a best practice within the industry.
