SafetySpect Inc., a California-based company, is developing the Contamination and Sanitation Inspection and Disinfection (CSI-D) device, which scans surfaces to find respiratory droplets and other substances not visible to the naked eye, but could endanger health.
Red River High School in Grand Forks will be the first test site for the device in the school system, said Chris Arnold, director of buildings and grounds for Grand Forks Public Schools. A prototype of the device was demonstrated for four high school custodians earlier this month, he said.
Custodians will be asked to use the CSI-D device and provide feedback that SafetySpect can use in product development, Arnold said.
“It’s one of those things we’re doing that nobody else in the country is doing,” he said. “It’s an exciting partnership — a really neat thing that Grand Forks Public Schools is a part of.”
“Patents have been issued, and patents are pending worldwide. There’s no one else in the world that can identify respiratory droplets besides us, visually,” Kenneth Barton, SafetySpect CEO, said.
SafetySpect is working with ComDel Innovation, in Wahpeton, N.D., to manufacture the device, Barton said, noting that his company is hopeful the first batch of devices will be ready for commercialization in January.
The hand-held CSI-D emits a structured (ultraviolet) light which causes biological contamination to light up on a screen, according to Barton.
Linked to the CSI-D is a tablet which shows an image that highlights saliva, general biological contaminants and fecal matter; each is color-coded.
The device can be operated at a safe distance from the contaminant, Barton said.
“The purpose of the device is, first of all, to make sure (custodians) are working in a safe environment, so we protect them and we protect the students , who are the most important, of course,” said Nejma Djabelkhir, who recently earned a doctorate in petroleum engineering at UND and heads an office SafetySpect has established at the UND Center for Innovation.
Her husband, Kouhyar Tavakolian, associate professor and director of the biomedical engineering program in the UND College of Engineering and Mines and principal investigator on the SafetySpect project, is among a team which is helping to develop the device.
While an operator conducts the scan, sensors will be placed on the operator’s body to detect the intensity of back-reflected UV light, according to a UND news release. Tavakolian’s team will study the results to gauge how much personal protection equipment will be needed for safe operation.
The use of the CSI-D was recently demonstrated on UND aircraft.
The SafetySpect scanner uses ultraviolet light to detect an enzyme in human saliva, making the saliva show up as bright white spots in the image on the tablet.

This semester, the SafetySpect system will be tested in UND labs, where researchers will “contaminate” various materials then assess the light’s safety and effectiveness at decontaminating them, according to UND.
“We’re using the CSI-D tool to identify respiratory droplets on sensitive airplane equipment that you cannot traditionally just spray down with disinfectant,” Barton said.
This use of UVC isn’t novel, but SafetySpect’s pairing of a tablet device to tune its visual output, as well as record the sanitation process, can provide administrators with improved record-keeping, through incident reports, and more accountability in matters of public health.
“All of the process will be recorded, time-stamped, dated and location-stamped in a digital record in the cloud,” said Fartash Vasefi, chief technology office at SafetySpect.
Other UV systems offer only the disinfection aspect.
“They don’t have the imaging and documentation to go with it,” he said.
In a school setting, if a student is ill and has symptoms, the device can be used to scan for respiratory droplets in a 10-foot area around that person’s desk, Barton said.
“We can’t say if the coronavirus is there, but we know the droplets shouldn’t be there,” he said.
The custodian can turn up the UVC LEDs and aim the device at surfaces in the area, so the contaminant is no longer harmful. Then the custodian can clean away the droplets in a safe manner, because any virus would have been neutralized by the UVC light, Barton said.
The feedback from custodians who use the device will help the company create a computer app that outlines Sanitation Standard Operating Procedures, or SSOPs, and draft protocols for its use in the workflow.
“That is important to us, because we need that feedback,” Barton said.
“North Dakota will be our first entrance to the public school system,” he said, noting that company leaders have given a presentation to State Superintendent Kirsten Baesler on the device and how it could be used in other North Dakota schools.
In addition to schools and the airline industry, SafetySpect leaders expect that the CSI-D device will be a valuable tool for restaurants, emergency vehicles, supermarkets, nursing homes, hospitals, hotels, public transportation vehicles and meat-processing plants.
