What Technical Safety Services does

Technical Safety Services (TSS) is a privately held, US-based provider of controlled environment testing, certification, and calibration services headquartered in Berkeley, California. Founded in 1969 and operating for more than 50 years, the company serves over 11,000 clients across biotechnology, pharmaceutical, medical device, healthcare, academic research, food production, electronics/semiconductor, and aerospace sectors. TSS is a portfolio company of private equity sponsor Levine Leichtman Capital Partners (LLCP) and employs 501–1,000 people, including what the company describes as the largest pool of NSF/ANSI 49 and CETA-certified technicians in the United States.

The company's service portfolio covers the full lifecycle of controlled environments: biosafety cabinet and cleanroom certification, HEPA filter integrity testing, ASHRAE-110 fume hood testing, airflow visualization, microbiological environmental monitoring, laboratory equipment calibration, decontamination (vaporized hydrogen peroxide and chlorine dioxide gas), high-purity water system testing, BSL-3/ABSL-3 commissioning, decommissioning and relocation, pharmacy compliance (USP <797>/<800>), and cGMP validation. Technology underpinnings include two ISO/IEC 17025:2017-accredited microbiology laboratories on both US coasts, MALDI-TOF Smart Biotyper instrumentation for species-level microbial identification, NIST-traceable calibrated sampling equipment, and proprietary digital systems — eData (21 CFR Part 11-compliant documentation), TSSConnect (customer portal for equipment inventory, certification records, and scheduling), and a validated LIMS for sample management and Chain of Custody.

TSS generates revenue through professional services — on-site testing, certification, and calibration — delivered by a nationwide dispatched field technician network, with quote-based pricing (no public rates) and free consultations as the primary acquisition motion. Distribution is direct enterprise field sales supported by content marketing (blog, white papers, FAQs) and organic LinkedIn presence. Since 2022, TSS has executed an aggressive roll-up strategy under LLCP, completing eight acquisitions (AL-TAR Services, CEPA Operations, AIRTEST, Northeast Medical Consulting, Airtest, Cornerstone Commissioning, Quality Systems Integration, Precision Air Technology, and Controlled Environment Management) to broaden geographic coverage across New England, the Southeast, the Southwest, and Southern California, while extending capabilities into commissioning, decommissioning, and pharmacy compliance.
