Sumitomo has its own laboratory, Safety Engineering Laboratory capable of conduct of studies and assessment of process safety and material safety.
A total of 2,592 material safety data measurements were taken in fiscal 2008, 68% of which measured thermal decomposition and thermal stability.

Sumitomo created and regularly updated a safety information database by collecting information on accidents in Japan and overseas and preparing abstracts of such accident cases. As of the end of March 2009, 30,510 data items were stored in the database (28,988 data items as of March 31, 2008). This system allows all employees at each Works or Research Laboratory to search stored abstracts, and their original data can be viewed or printed at individual terminals. This data is also used in process hazard evaluations and case study examinations to prevent similar accidents.
