1. Hydroxyl radicals only work to remove certain types of odors.

• True
• False

Answer:"Scientifically, hydroxyls are one million times more reactive than ozone. This means that they will disassemble a much larger range of odors and VOCs."

2. What does the relative humidity need to be in the work space for hydroxyl generators to work properly?

• 80% relative humidity
• 60% relative humidity
• 25% relative humidity
• It doesn’t matter.

Answer:"Hydroxyl generators using the patented technology will be effective with humidity as low as 5%. Contractors should never have to add humidity for their hydroxyl generators to work, particularly since this is counterproductive to most projects they are on."

3. Hydroxyl generators can be on around people and contents without safety concerns.

• True
• False

Answer:"Hydroxyl generators do not exacerbate the safety risk one encounters in post-fire environments. Instead, they rapidly break down complex compounds and expedite the cleaning process."

4. For contents restoration, hydroxyl is effective because:

• It removes odor from any material.
• It is not caustic.
• It does not leave a residual chemical-type odor.
• All of the above.

Answer: Annissa takes on the ozone vs. hydroxyl debate!

5. Which does not impact the severity of smoke odors?

• Size of the fire.
• Size of the affected area.
• Number of people affected by the fire.
• Length of time the structure was exposed to smoke.
• Amount of contents in the affected space.

Answer:"When eliminating malodors on fire jobs, remember that there are several factors that can impact the strength of the odor…"
