Which of the following is important for ensuring safety in environments with toxic substances?

Ventilation
Hiding the substances
Minimizing spacing
Avoiding training

The correct answer is: Ventilation

Ensuring safety in environments that contain toxic substances is critically dependent on adequate ventilation. Proper ventilation helps to dilute and disperse harmful vapors or fumes, thereby reducing the concentration of toxic substances in the air. Good airflow ensures that any hazardous gases are regularly replaced with fresh air, which is essential for maintaining safe breathing conditions for workers and minimizing the risks associated with exposure to toxins. In contrast, the other options do not contribute effectively to safety in environments with toxic substances. Hiding substances would not eliminate the risks associated with exposure; in fact, it could exacerbate safety issues by concealing potential hazards. Minimizing spacing might refer to reducing the distance between substances, which can actually increase the risk of exposure and complicate emergency responses. Lastly, avoiding training would leave workers unprepared to handle toxic substances safely, making them more vulnerable to accidents and exposure. Therefore, implementing effective ventilation is a key practice for maintaining safety in such environments.
