Linking chemical accident substances
to Korea's regulatory lists

We resolved the substance names in Korean chemical accident records to CAS numbers and linked them to the four designation lists under the Chemicals Control Act. The list below shows accident substances designated as hazardous chemicals but not as accident preparedness substances, by number of accidents.

Enter your worker count and the substances you use to check occupational safety duties.

Check duties for your workplace

There is also a card for each substance in the annexes, with the original text and the conditions that make it apply.See substance duty cards →

Duty check

Check your workplace duties

Enter your regular headcount and the CAS numbers and concentrations of the substances you use. For each duty you get whether it applies, the legal basis, the base fine and the next due date. ONTOFLOW computes the result with rules transcribed from the Korean Ministry of Government Legislation texts.

What you enter is used only for the check and is not stored by this website.

  1. 1. Number of regular workers
  2. 2. Substance (CAS) and concentration
  3. 3. Check duties
First time here? Try the example first.
workers

If left empty, the Serious Accidents Punishment Act duty comes back as Cannot determine.

Substances you use

The check matches by CAS number. A name alone is not matched against the annexes and comes back as Cannot determine, so that substances sharing a name are not mixed up.

  1. Substance 1

    pH is used only for substances whose annex entry has a pH condition (for example, sulfuric acid).

Enter 100 for a pure substance. Up to 50 substances.
Last dates (optional)

With these, the next due date and whether it has passed are computed.
