The first step in cleaning a Self-Contained Breathing Apparatus (SCBA) involves rinsing the entire unit with clean water from a hose. This initial rinsing process helps to remove surface contaminants such as dust, dirt, and other debris that may have accumulated on the SCBA during use. By using clean water, you ensure that any harmful particles are washed away before proceeding with more thorough cleaning steps, such as disinfection and drying. This foundational step is crucial for maintaining the integrity and functionality of the SCBA, preventing contamination, and ensuring that the equipment is safe for future use.
