SIMPSON UNLIMITED INC
Federal OSHA safety record across 15 records in 3 states.
These records may not all be the same company. The 15 records filed under this name come from 3 states (DC, MD, VA) and unrelated industries (Administrative, Support, Waste Management, Construction). Because records are grouped by normalized name and not by legal entity, this profile probably combines more than one unrelated business, and the totals above should not be read as any single company's record. Treat each record's own employer name, location, and industry as authoritative.
How these records are matched, and what they cover. Records are grouped by normalized employer name — nothing in OSHA's published files ties them to a legal entity. Unrelated companies that happen to share a name are combined onto one profile, and there is no EIN, address, or parent-company check to separate them; conversely, one company filing under several spellings can appear as several profiles. Severe-injury data covers establishments under federal OSHA jurisdiction only: about 22 states run their own OSHA-approved state plans, and severe-injury reports from those states are not in OSHA's published federal file. Verify against the linked OSHA source records before drawing any conclusion about a specific company.

Sources
This profile aggregates federal OSHA records from three published feeds: OSHA Severe Injury Reports, the ITA Establishment-Specific Injury and Illness Data (Form 300/301), and the U.S. Department of Labor Open Data API (OSHA inspections). Records are matched to this employer by normalized name only. That has two consequences worth stating plainly. Small variations in spelling, punctuation, and capitalization collapse to one profile — but so do unrelated companies that happen to share a name, because the published records carry no EIN, parent-company, or address key we can use to tell them apart. And a single company filing under materially different legal names (parent vs. subsidiary, or a distinct hyphenated spelling) will appear here as more than one profile, each showing only part of its record. Coverage is federal only: severe-injury data covers establishments under federal OSHA jurisdiction, and about 22 states run their own OSHA-approved state plans whose severe-injury reports are not in OSHA's published federal file. Verify every record against the OSHA source linked from its detail page.
