About CAS numbers, the example and our sources

Have the MSDS (Material Safety Data Sheet) of your product ready. It lists the CAS numbers and concentrations.

A CAS number is the unique number assigned to each chemical substance. Benzene is 71-43-2. Look in section 3 of the MSDS, composition and information on ingredients, for the number and concentration. If they are not listed, ask the product supplier.

The example is a site with 20 workers using a product with benzene (71-43-2) 2% and toluene (108-88-3) 5%, last measured on 2026-04-01.

The source is the statutory text from Korea's National Law Information Center (received 2026-10-25). Statutes used: 중대재해 처벌 등에 관한 법률 · 산업안전보건기준에 관한 규칙 · 중대재해 처벌 등에 관한 법률 시행령 · 산업안전보건법 · 산업안전보건법 시행령 · 산업안전보건법 시행규칙. Annexes and effective dates are in the statute list below. Written in Korean

Values were extracted from the statutory annex tables by a parser and tested against 40 reference cases (142 rows) built from the statutory text. Not yet reviewed by experts.

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. Check the unit in section 3 of the MSDS. If you leave it as unknown, the result comes back as conditional. Up to 50 substances.
Last dates (optional)

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