Hilger Crystals achieves ISO 45001: 2018 Occupational Health and Safety Certification

NEWTON, Mass., September 22, 2020 - Dynasil Corporation of America ("Dynasil" or the "Company"), a leading developer and manufacturer of optics and photonics products, optical detection and analysis technology and components for the homeland security, medical and industrial markets, today announces that its subsidiary Hilger Crystals has achieved certification for the ISO 45001:2018 Occupational Health and Safety Standard.

It is the first of all Dynasil subsidiaries to meet accreditation of the three integrated management systems standards: ISO 9001, ISO 14001, and now ISO 45001.

ISO 45001:2018 specifies an international benchmark for organizations to identify, control, and decrease risks associated with occupational health and safety and an organizational commitment to continual improvement of its systems to ensure an ever safer and healthier workplace. Adherence to this standard also improves overall business performance by increasing productivity and reducing workplace illness and injury.

"This certification marks an important goal for Hilger in optimizing our productivity, while reaffirming our commitment to workplace health and safety. We strive to provide safe and secure processes throughout our facility – from crystal growth to machining and assembly and on through packaging and shipping. This certification gives our employees and customers reassurance that we have robust safety processes in place", said Jim Telfer, general manager of Hilger Crystals. “We could not have achieved this without the support of all our employees. I’m very proud of our entire team for their notable and sustained efforts to reach this goal, and during a global pandemic no less." Both the audit of the Hilger Crystals processes and facilities and certification was provided by BSI (certificate number OHS 718450).
