Enviro-STAR, Inc.
HEPA filter testing, safety training and site inspections from San Leandro.
Acerca de
The name is an acronym. Enviro-STAR, Inc. stands for Environmental Safety, Training, and Resources, Incorporated, and the three words after the hyphen are the three things it does: field testing of HEPA filtration systems, safety training programs, and inspections and surveys of buildings and workplaces. Ralph Guzman is the president. The office is at 2194 Edison Avenue, Suite I, in the light-industrial grid of west San Leandro between Interstate 880 and the Oakland airport, an easy base for a firm whose work happens at other people's sites.
Three service lines
DOP testing checks that a HEPA filter and its housing actually stop the particles they are meant to stop. A technician introduces an aerosol upstream, scans the filter face and seals downstream, and records any leak; hospitals, laboratories, cleanrooms and abatement contractors need this done on a schedule and after any filter change. Enviro-STAR asks that tests be booked at least a day ahead.
Safety training covers the courses that regulators expect employers to provide before staff handle hazardous materials or enter regulated spaces. Inspections and surveys are the third line: walking a building or a job site, sampling where needed, and writing up what was found. Directory listings add asbestos, lead and mould work to that list, which the firm's own site does not spell out, so ask.
Scheduling a test or a class
Give the firm the filter make, size and location, or the course and headcount, when you call, and allow at least twenty-four hours for DOP testing or a survey. Ask for a written scope and what the report will contain, whether a failed filter can be re-tested on the same visit, and, for training, whether the class can be delivered at your site and in which languages. If a regulator or a client is waiting on the paperwork, say so at booking.

Preguntas frecuentes
Típico de este tipo de negocioHow often does a HEPA filter need DOP testing?
It depends on the setting and the rules that apply to it. Hospitals, laboratories and cleanrooms commonly test annually and after any filter change or housing repair; ask which standard your site falls under and keep the reports on file.
What information does the tester need before the visit?
The filter make and size, where it is installed, how it is accessed, and whether the system can be shut down or must be tested in operation. Give at least a day's notice so the visit can be scheduled.
Can safety training be held at our workplace?
Many firms deliver classes on site for a group. Ask about the minimum headcount, the length of the course, which languages it can be taught in, and what documentation attendees receive afterwards.
What does an inspection report include?
Ask before booking. A useful report describes what was inspected, any samples taken and their results, the findings in plain language, and recommended next steps, so that a contractor or regulator can act on it.
