No limit values? Then kick-off  values are possible! 

DOHSBase contains exposure limits for many thousands of substances. The limit values are obtained from various national and international sources, following an adapted version of the hierarchy of the SER guidelines “Working Safely with Chemical Substances”. 

Is there still no limit value to be found? Then you can use the kick-off values, developed by DOHSBase. The kick-off values are based on the “hazard banding” system. More info? click here

The use of kick-off values means that limit values are available for many additional substances, with which the requirements of the Self-inspection of Hazardous Substances can be met. Kick-off values will be accepted by I-SZW if there are no other limit values available.

De Compare® functionality

With the unique Compare® mode you can simultaneously acces up to thirty hazardous substances on their risk potential, even in mixtures. This is a powerful tool if you want to replace a dangerous substance with a less dangerous variant from the ISZW Self-Inspection Tool! After all, replacement is the highest level of measures according to the occupational hygiene strategy.

DOHSBase Compare® ranks substances in four hazard bands (TOX). For the substances with a relevant vapor pressure, the TOX is combined with the relative volitality relative to the limit value (TIX). The TOX and TIX product provides the risk potential (Risk Assesment Score = RAS). This indicates whether a replacement has a lower risk with equal use. More info? Click here.
