Which of the following is NOT a method to ensure safety in confined spaces?

To ensure safety in confined spaces, it is vital to implement adequate ventilation strategies to reduce the risks associated with hazardous atmospheres. Adequate ventilation helps to disperse harmful gases, vapors, or airborne contaminants, enabling a healthier environment for workers. Ignoring ventilation needs can lead to dangerous situations, such as oxygen deficiency or the accumulation of toxic gases, increasing the risk of accidents and health issues for individuals working in those spaces.

On the other hand, regular atmospheric monitoring, use of personal protective equipment (PPE), and training workers on hazards are proven methods that contribute to safety. Monitoring helps in identifying toxic levels early, PPE provides a barrier between workers and potential hazards, and training educates workers about risks and safe practices. All these measures are crucial for maintaining a safe working environment in confined spaces, while neglecting ventilation is a significant oversight that can lead to catastrophic outcomes.
