Hi,
I was performing MTT assay in my lab hood. Accidentally, I did not turn off germicidal lamp (UV-C 254 nm) in the hood and I worked for about 25 minutes. I was wearing latex gloves and my hands and arms were completely covered in my labcoat and also my winter coat. My face however was uncovered and I was wearing my glasses. There was hood glass between the lamp and myself and the distance between my face and lamp was as usual as in normal airflow hoods.
This happened 4 days from writing this post. After overexposure, I did not see any symptoms like burns in my cornea or erythema so far. I am really scared as to what fate awaits me after 6-12 months as they say this can lead to skin cancer.
I would be really grateful if anyone could suggest on what I should do and what fate awaits me in the next one or two years.
Regards,
Pratik
What is the transmission of the of latex gloves, labcoat, winter coat, glasses, hood @254 nm ?
I would expect the hood glass not to be glass but rather some kind of plastic and therefore assume, that its transmission @254 nm should be very small. Which makes me assume, that nothing should really be happen to you. Did you get some kind of "sun burn" on you hands ? If not, than the reaction of your body will most likely show, that it was not overexposed to UV.
Keep up the good work while following the lab safety rules.
Thank you Mr. Martin. I have not got any sunburns or any sorts of issues with my skin. The problem is skin cancer symptoms would not be seen until 6-8 months after exposure. So, I am worried on the same.
