Using improper respiratory protective equipment significantly increases the risk of respiratory illness. Proper respiratory protection is designed to filter out harmful particulates, gases, and vapors that workers may encounter in hazardous environments. If the equipment is not suitable for the specific contaminants present, or if it fails to establish an adequate seal, it may not provide the required level of protection. This exposure can lead to serious health issues, including chronic respiratory diseases, lung damage, and other significant health complications.

The other options, while appealing, do not directly relate to the consequences of using improper respiratory equipment. Improved visibility and enhanced comfort may be subjective benefits that do not address the primary concern of respiratory safety. Faster work completion is also not a valid consequence; in reality, improper protection could lead to work stoppages due to health-related issues, thereby delaying project timelines. Thus, the main takeaway is that using the correct respiratory protective equipment is crucial for safeguarding workers' health.
