What is a necessary safety practice when working in confined spaces?

Using personal protective equipment (PPE) at all times is essential for ensuring safety when working in confined spaces. Confined spaces often present various hazards, including limited mobility, poor ventilation, and the potential for toxic atmospheres or dangerous substances. PPE can include items such as respiratory protection, helmets, gloves, and protective clothing, which help mitigate these risks.

The importance of PPE cannot be overstated; it provides a barrier against injuries that might occur from environmental hazards or physical objects within the confined space. For example, respiratory protection is critical if there are harmful fumes, while a helmet protects against falling objects. Proper PPE enables workers to perform their tasks with a reduced risk of injury or exposure to hazardous conditions.

This practice ensures workers are prepared for unexpected situations that may arise in confined spaces, making it a fundamental component of safety protocols in those environments. In contrast, the other options involve practices that could increase the risk of safety incidents, such as not having a backup team or failing to secure tools appropriately.
