For Petrochemical Sampling, Safety Is First In Sampler Design

Posted by Sentry Equipment on 9/2/15 10:00 AM


In the petrochemical industry, representative samples of liquid petroleum gas and other high vapor pressure gases and liquids are needed for process monitoring, quality control and regulatory compliance. However, in this industry, process fluids and gases are volatile or could be harmful to the operator and the environment, or they could be dangerously altered through a chemical reaction when exposed to the atmosphere – so exposure must be avoided. Because each sample collected may pose a physical or health hazard, and operators may take hundreds of samples per year, samples must be taken safely and correctly using the appropriate equipment and containers.

Why Does Employee Ownership Matter?

Posted by Sentry Equipment on 7/29/15 10:00 AM

In 1985, Sentry Equipment Corp owners Dick and Mary Henszey had the vision and foresight to ensure the company and employees would continue to thrive. They did this by beginning the process of shifting ownership of the company to employees through an Employee Stock Ownership Plan (ESOP).

The plan, designed to secure the company’s and employees’ future, transferred ownership from the Henszeys to all employees over a period of time, with the Henszeys personally guaranteeing the financial obligation associated with the transfer of ownership. While ESOPs were not an entirely new concept, this method of ensuring the financing was creative, and eventually became a model for other ESOP companies.
