What safety measures should be taken when working in confined spaces?

Ensuring proper ventilation and following entry protocols is essential when working in confined spaces due to the potential hazards associated with these environments, such as the presence of toxic gases, low oxygen levels, or the risk of engulfment. Proper ventilation helps to maintain safe air quality by reducing the concentration of harmful substances and providing a supply of breathable air. Following established entry protocols ensures that all safety measures are adhered to, including monitoring atmospheric conditions, having emergency rescue plans in place, and using appropriate personal protective equipment.

The other choices do not address the critical safety considerations necessary for confined space work. While standard gloves may offer basic protection, they do not provide comprehensive safety measures. Working in teams, while beneficial for communication and support, does not inherently address the physical safety risks present. Similarly, using electric tools may be advantageous, but if not accompanied by proper safety measures such as ventilation and protocols, it does not ensure a safe working environment.
