Frequently asked questions

Below you can find answers for many of the frequently asked questions about STERISAFE’s whole room disinfection technology

Question

What is the maximum room volume/capacity a STERISAFE PRO can disinfect? 

Answer

130m3 is the maximum room size where STERISAFE PRO can guarantee that the entire room will be homogeneously disinfected for hospital grade disinfection (up to 99,99999% reduction of microorganisms).
The 130m3 is related to the air circulation in the room based on the fans of the STERISAFE PRO robot and ensures that the ozone gas will be dispersed to all cracks and corners at a concentration of 80ppm.
For larger rooms one or more units will be required.

For industries that does not require hospital grade disinfection but will suffice with a 99,99% reduction of microorganisms larger rooms can be treated with only one STERISAFE PRO

Question

How long time does the disinfection cycle take? 

Answer

The STERISAFE PRO’s disinfection cycle are split into 3 phases; build up – disinfection (dwell time) - Purification. The disinfection (dwell time) is always fixed to either 30, 60 or 90 mins depending on needs. The build up and purification phase varies depending on the size of the room. Build up takes no more than 5-10 min but the purification phase takes longer due to safety precautions. For the healthcare facilities the average time for a full cycle is 2,5 – 3 hours for a 130m3 room (maximum capacity) and up to 99.99999% reduction of microorganisms.
For application other than the healthcare sector, shorter cycles of 30 min - 1 hour can be achieved at the expense of lower reductions of microorganisms 99.99%. 

Question

What cycle would you recommend? Short, medium or long?

Answer

The cycle of a STERISAFE PRO depends on your needs.
When you acquire a STERISAFE PRO disinfection robot you will receive extensive training by professionals, to determine the needs of your organization.
Normally it is recommended to use short cycles for general prevention, medium cycles for terminal cleaning and long cycles for containment of outbreaks etc.

Question

What are the consumables and running costs of STERISAFE PRO?

Answer

STERISAFE PRO consumes only water (approx 1l pr. cycle) and electricity.
The running costs is therefore extremely low compared to most disinfection alternatives

Question

Are your disinfection technology efficient against coronavirus?

Answer

Yes, STERISAFE PRO's disinfection cycle is effective against coronavirus.
Our technology have been accredited and tested by thirds party laboratories, see our efficacy page for more info.

Question

Is the use of ozone dangerous for my staff? 

Answer

Like any other disinfection alternative, direct contact with ozone can be dangerous. Ozone is a highly effective oxidizing agent, with known adverse health effects to people but that is why we have made safety our first priority and we have ensured that every precaution have been taken to make the STERISAFE PRO safe to use for everyone. Every STERISAFE user will undergo an operational training that will make them experts in using our robots.
STERISAFE PRO should only be used by trained personnel and the STERISAFE guidelines and safety precautions should be followed at any time according to the manual for safe use.

Question

Are there any materials that cannot withstand ozone?

Answer

Most materials have a high tolerance towards ozone. However, natural rubber, iron and Nitril are the most common types of material that should be removed from the room during a disinfection cycle.
Electronic equipment does not take damage by ozone and can safely be disinfected together with the dedicated room

Question

What is the alert threshold for ozone exposure? 

Answer

According to the European Environmental Agency and The World Health Organization the safe daily 8-hour maximum exposure of ozone is 100 μg/m3 (= 0.10 ppm).
When STERISAFE PRO finishes a disinfection cycle the ozone concentration in any given room with be 100 μg/m3 (= 0.10 ppm). However due to ozone's naturally fast deterioration rate the concentration will quickly drop to 0.00 ppm after entering the room. 

Question

How to ensure that there is no ozone in the room after disinfection?

Answer

The STERISAFE PRO will monitor the ozone levels in the rooms at all times. This can be followed and monitored via a wireless device.
the STERISAFE PRO will revert ozone back into oxygen and when the room is safe to enter, it will be indicated on the wireless device connected to the unit

Question

How do i know if there is a leak of ozone?

Answer

A leak of ozone occurs if the precaution instructions are not followed correctly. it is recommended to use STERISAFE's handheld ozone monitors to check for leakage.
In the case of a leak, it is important to locate the point of leakage and seal it properly. Notice that if there is a leak, the concentration of ozone will deteriorate fast and rarely become a safety issue.
Larger leaks can typically be noticed if the robot is having difficulties building up the sufficient ozone concentration. This could indicate open windows or insufficiently sealed ventilation channels. If larger leaks should occur, the "Abort" button should be pressed on the tablet and the STERISAFE PRO will immediately begin a purification phase and stop the production of ozone. A potential leak can be noticed immediately before it causes any safety issues.

Question

How do I know when I can enter a room after disinfection?

Answer

The STERISAFE PRO is connected to a dedicated tablet that will tell you when the room is safe to enter. The STERISAFE PRO is monitoring ozone levels in the room at all times and can therefore ensure that the room is safe to enter.

Question

How can I ensure that the room have been disinfected properly?

Answer

Besides the fact that our STERISAFE PRO robot have been validated by multiple third party laboratories, it is the sensor and monitoring technologies that are key for proving a successful disinfection.
STERISAFE PRO monitors relative humidity and ozone levels during the disinfection cycle, two variables that are equally important for successful disinfection. The wireless tablet connected to the robot will let the operator know if these variables have been satisfactory to deliver the high level of disinfection that we guarantee.
