NFPA-99 Practice Exam

When cleaning tools for medical gas work, which type of cleaner is permissible?

1. The natural citrus solvent cleaner/degreaser.

2. Group or Gojo hand cleaner.

3. Trisodium phosphate or sodium carbonate.

4. Water.

The correct answer is: Trisodium phosphate or sodium carbonate.

The correct choice indicates that cleaning tools for medical gas work with trisodium phosphate or sodium carbonate is permissible. These substances are effective at removing grease, oil, and other contaminants, making them suitable for ensuring that tools are properly cleaned and free of residue that could interfere with medical gas systems. The use of trisodium phosphate or sodium carbonate is particularly important in the context of medical gas applications, as they are non-residue forming and do not leave harmful residues that could affect the safety and functionality of the medical gas supply. For cleaning tools specifically used in medical gas applications, it is crucial to avoid cleaners that might leave residues or harmful substances. Certain other options, while they may be effective cleaners in different contexts, might not provide the required cleanliness levels or could introduce contaminants. Therefore, the focus on trisodium phosphate or sodium carbonate aligns with the established standards for maintaining the integrity and safety necessary for equipment that interacts with medical gases.
