Ultrasonic & Ozone Content Cleaning Flashcards

During ultrasonic cleaning, a technician observes excessive foaming in the tank that is reducing cavitation. What is the most likely cause?

Answer: Too much cleaning concentrate or a soap-based solution incompatible with ultrasonic use

Excess foaming is typically caused by over-concentrated or soap-based solutions that dampen cavitation and dramatically reduce cleaning effectiveness.

What factor most significantly determines the required ozone output and treatment duration for fire-damage deodorization?

Answer: The volume of the space and the concentration of odor-causing compounds present

Space volume and contamination concentration determine how much ozone must be generated and how long treatment must run to achieve adequate deodorization.

An ultrasonic tank that previously cleaned well is now showing significantly reduced cavitation with the same solution and settings. What component should be inspected first?

Answer: The transducer for fouling, scaling, or damage

Fouled or damaged transducers are the most common mechanical cause of reduced cavitation, as mineral scaling or physical damage impairs their ability to transmit ultrasonic waves.

A rubber gasket is accidentally left inside an ozone treatment chamber when the generator is activated. What is the correct immediate response?

Answer: Shut off the generator immediately and ventilate the chamber to prevent ozone degradation of the rubber

Immediately stopping ozone production and ventilating the chamber is the only correct response; ozone degrades rubber rapidly and ventilation removes residual ozone quickly.

Which practice represents an unsafe and improper use of ozone in a residential restoration setting?

Answer: Operating ozone treatment while residents, pets, or plants remain anywhere in the structure

Ozone concentrations required for effective restoration deodorization are toxic to humans, animals, and plants — occupied structures must never be treated.

What does the term 'ozone shock treatment' specifically refer to in the restoration industry?

Answer: Applying high-concentration ozone to an unoccupied sealed space over an extended period to oxidize persistent odors

Ozone shock treatment means flooding an unoccupied, sealed space with high-concentration ozone for several hours to oxidize deeply embedded odors and microbial contamination.

After ultrasonic cleaning, items exhibit white mineral deposits and water spots on their surfaces. What is the most effective practice to prevent this outcome?

Answer: Use distilled or deionized water for all final rinse cycles

Distilled or deionized water contains no dissolved minerals, eliminating the deposits that tap water leaves behind when it evaporates from cleaned surfaces.
