About the CAS Chemical Safety Library

The CAS Chemical Safety Library is a repository for the scientific community to capture and confidentially share hazardous reaction information from real-world laboratory experiences to reduce and prevent incidents. Information in the library is publicly available and uploaded to PubChem.  

The repository is overseen by an advisory panel made up of experts from CAS, ACS, and academic, industry, and non-profit organizations worldwide.

Pistoia Alliance Logo

Prior to September 1, 2023, the Chemical Safety Library was created and maintained by Pistoia Alliance.

The use of dangerous chemicals in the laboratory can lead to major risks. To prevent related disasters, hazardous reaction incident information must be shared across the global research community. With the CAS Chemical Safety Library:

Search

Learn about hazardous reaction information before you head to the laboratory. Search by CAS Registry Number®, chemical name, SMILES, and more.

Contribute

Help make the library even more valuable to other researchers by submitting your hazardous reaction incident information.

Download

Integrate hazardous reaction information from the library with your internal workflows and knowledge bases.

Chemical Safety Library timeline

Fall 2016

A presentation by Mark Manfredi (Bristol Myers Squibb) at ACS Fall 2016, “Ensuring That Lessons Learned Are Not Forgotten, Leveraging ELN to Transform the Safety Paradigm”, inspired the idea for a simple crowd-sourced hazardous reaction data collection system. Further championed by Ramesh Durvasula (Lilly), the Pistoia Alliance led the development of the Chemical Safety Library.

Spring 2017

Hazardous reaction information from Bristol Myers Squibb was added to the Pistoia Alliance Chemical Safety Library, which was then expanded through datathons, hackathons, and data extraction from C&EN Safety Letters and other sources.

Winter 2018 - Spring 2020

A simplified submission system helped the Pistoia Alliance Chemical Safety Library reach 138 records. Data was made available to users through .csv file requests and the entire library was shared with PubChem (National Library of Medicine).

Summer 2020 - Spring 2024

CAS began hosting the Pistoia Alliance Chemical Safety Library and established the Advisory Panel, chaired by Carmen Nitsche (The Cambridge Crystallographic Data Centre) and Mark Manfredi (Bristol Myers Squibb) to drive future development. A strategic partnership with the Campus Safety, Health, and Environmental Management Association (CSHEMA) was also established and extended outreach to academia. A reusable data collection protocol (Chemical Safety Library in a Box) was developed through data mining projects with Purdue University and the University of Minnesota.

Spring 2024

Chemical Safety Library in a Box was deployed at UCLA and promoted at CSHEMA Safety Week. In March, a datathon was hosted at ACS Spring 2024 to expand the information collection. The resource was officially renamed “CAS Chemical Safety Library” after ownership was transferred from the Pistoia Alliance to CAS. Today, the CAS Chemical Safety Library includes more than 500 records.

CAS Chemical Safety Library™ Advisory Panel
