OEL Atlas is built to make defensible exposure-limit lookup faster, clearer, and easier to navigate across jurisdictions.
Browse occupational exposure limits across U.S. and international sources from one app instead of juggling disconnected files and bookmarks.
Search by chemical name, synonym, or CAS-style reference information to get to the relevant limit faster when time matters.
Use a map-driven explorer to move between jurisdictions and understand which source library or region you are pulling from.
Keep the reference source close to the result so you can quickly understand the origin of the limit and follow up when documentation is needed.
Designed around the way industrial hygienists and occupational health teams actually compare limits during surveys, planning, and record review.
A dedicated OEL lookup experience for professionals who want exposure reference access without opening a much larger toolkit first.
Move from question to answer quickly, then keep the supporting context nearby.

For anyone making chemical safety decisions across more than one jurisdiction
Staff writing one standard for sites in several countries, who need to know whether Germany, Japan, or Australia sets a stricter limit than OSHA before the policy is published.
IHs checking a substance against ACGIH TLVs, OSHA PELs, and NIOSH RELs side by side rather than opening three references in sequence.
Consultants advising clients who operate across borders and need a defensible, sourced answer in the meeting rather than after it.
Leaders who need exportable comparison sheets for the compliance file and a clear view of which chemicals carry carcinogen designations.
Teams assessing where a formulation runs into the tightest exposure limit worldwide.
Practitioners who need the whole picture offline, on a plant floor with no signal.
What people ask before subscribing
OEL Atlas is a subscription app and includes a 30-day free trial, so you can work with the full database before paying anything. A military and veteran discount is available in-app. Subscriptions are billed through the App Store and can be cancelled anytime in your App Store settings.
Data from 30+ regulatory bodies across 22 countries. That includes OSHA, NIOSH, and ACGIH in the United States alongside German, Japanese, Australian, Singaporean, and 26 other jurisdictions' limits for direct comparison.
Most tools show one jurisdiction's rules. OEL Atlas shows them together. The Chemical Heat Map surfaces which jurisdiction sets the strictest limit for a substance at a glance, and the World Map lets you tap a country to pull its data immediately — a breadth of side-by-side comparison that doesn't otherwise exist on iOS.
Yes. The full database is bundled with the app, so a plant floor, a basement, or a flight with no connectivity doesn't stop you working.
Yes. Generate PDF comparison sheets covering the jurisdictions you selected, with sources attributed, so the reasoning behind a control decision is documented.
Yes. Chemicals carrying carcinogen designations from OSHA, ACGIH, or IARC are flagged, so a substance that needs different handling doesn't slip past on the exposure number alone.
