Frequently Asked Questions
Can’t I just find the hazard classes on the safety data sheet (SDS)?
No. Material safety data sheets (SDS) do not generally provide hazard classifications for materials based on the International Fire and Building Code hazard class definitions. SDS provide classification based on the UN Globally Harmonized System (GHS) adopted by OSHA and the US Department of Transportation (DOT) system used specifically to address the hazards of materials in transportation.
HMEx chemical classifications and hazard ratings are assigned by a team of technically qualified chemists, chemical engineers and industrial hygienists. We’re committed to providing classifications based on best available documentation and research.
Who classifies the chemicals?
Our team consists of highly qualified Ph.D. chemists, chemical engineers, and special experts who evaluate and classify materials using technical references, safety data sheets, code definitions and professional judgement.
Why do I need to include a safety data sheet (SDS)?
In some cases, the best information about the material or product hazards comes from the manufacturer. Where little information is known or available in technical references, we may rely on the SDS to evaluate a material’s hazardous properties.
What if I have IP chemicals with little or no information?
In many high-tech and research and development industries, it is not uncommon to encounter materials that are a company’s intellectual property (IP), and few details of the chemical components are available or listed on the SDS.
HMEx allows ‘user-classified’ chemicals and identifies them on the Inventory Statement, so code officials can determine whether to accept the classifications or require further review.
Our classification team will not classify chemicals if there is not sufficient information to make sound decisions.
Will I be notified when my chemicals are available in the database?
We’ll do our best to let you know when the chemicals you recommend are available in the database. But the best way to stay informed and up to date on all the latest product enhancements and new features is to sign up for our quarterly Newsletter. We promise not to bombard your inbox, and you can unsubscribe any time!
