Using local exhaust ventilation or respiratory protection is essential for preventing fume and gas exposure in confined spaces because these methods actively reduce the concentration of harmful substances in the air. Local exhaust ventilation systems are designed to capture and remove fumes, vapors, and gases at their source before they can be inhaled. This is particularly important in confined spaces where airflow may be limited and harmful pollutants can accumulate quickly.

Respiratory protection, such as masks or respirators, provides a barrier between the worker and the hazardous environment, ensuring that the air inhaled is free from harmful contaminants. This combination of proper ventilation and personal protective equipment is crucial in maintaining a safe working environment and protecting the health of individuals working in confined spaces.

Other methods, such as sealing a space tightly or working quickly, do not effectively mitigate the risks associated with fume and gas exposure, while simply wearing a standard mask may not provide adequate protection in environments with specific hazards present.
