Misją Instytutu jest dzialalność naukowo-badawcza prowadząca do nowych rozwiązań technicznych i organizacyjnych użytecznych w kształtowaniu warunków pracy zgodnych z zasadami bezpieczeństwa pracy i ergonomii oraz ustalanie podstaw naukowych do właściwego ukierunkowywania polityki społeczno-ekonomicznej państwa w tym zakresie.
Assessment of thermal hazard of the cornea and lens of the eye with IRA and IRB radiation in the range of 780 - 3000 nm
Program supporting assessment of thermal hazard of the cornea and lens of the eye with IRA and IRB radiation in the range of 780 - 3000 nm
The initial values for hazard assessment are:
EIR – eyes irradiance (marked in program as E_IR), in [W/m2],
ti – one-time exposure time in a work shift (marked as. t_i), in [s].
Occupational risk assessment is performed in relation to the applicable admissible values, specified in the Regulation of the Minister of Family, Labor and Social Policy of 12 June 2018 on the highest allowable concentrations and intensities of factors harmful to health in the work environment (Journal of Laws 2018 item 1286). According to the ordinance, the value used to assess the thermal hazard of the eye's cornea and lens with IRA and IRB radiation is eye's irradiance, EIR, in [W/m2]. For this quantity, the maximum exposure value (MDE) is determined as a function of one-time exposure time.
Based on the entered values, the program calculates the value of MDE, MDE times, k, and evaluates the occupational risk resulting from these values. In addition, the program determines the value of the permissible one-time exposure time, tp (marked as t_p), in [s]. Detailed principles of occupational risk assessment are presented in the chapter "Principles of assesment".
Color marking in occupational risk assessment:
green - low risk,
yellow - medium risk,
red - high risk.
Using the program:
Enter the value of the eye's irradiance E_IR and the one-time exposure time in the appropriate fields of the program. The entered values should be confirmed with the Enter key.
