Robot causes eye irritation
Some media members who covered the demonstration of a state-of-the- art UVC robotic disinfectant work at Baguio Convention Center (BCC) over the weekend complained of eye irritation shortly after the event.
The demonstration conducted at the lobby of the newly rehabilitated BCC showcased the technological capability of the city in its battle against the coronavirus disease 2019 (COVID-19).
It coincided with the visit of presidential spokesperson Harry Roque and National Action Plan Against COVID-19 deputy chief implementer Vince Dizon, who observed the preparations of the Baguio City government before reopening tourism to visitors from Region 1 on Tuesday.
Three media members recalled getting near the robot, although they were told to observe a distance of at least five meters away.
The three were initially diagnosed to have suffered from minor cornea damage while a photojournalist complained of conjunctivitis (sore eyes) symptoms like itchiness and redness.
Other media members who went to the activity were likewise advised to have their eyes checked.
UVC (ultraviolet-C) light has wavelengths between 200 to 280 nanometers. The UVC light can be used for disinfecting water, sterilizing surfaces and destroying harmful micro-organisms in food products and in air. It is believed to be effective in getting rid of the coronavirus on surfaces and in the air.
Doctors say prolonged exposure to UVC can cause photokeratitis (painful eye), like the feeling of sunburn; photo conjunctivitis or red eye, a condition that causes inflammation and redness of the lining of the white portion of the eyes and membranes surrounding the inner eyelids; and first and second-degree skin burns.
Medical experts advise people to leave an enclosed room when the UV light is on and not to expose eyes and skin to the UV. They also warned that some UVC lamps may cause respiratory irritation to those with pre-existing respiratory problems.
