Quest & Metrosonics® Heat Stress Monitors First to Receive ATEX Intrinsic Safety Approval.

Press Release, Oconomowoc, WI, April 21, 2004

Monitors protect industrial & service industry workers and first responders to bioterrorism.

Quest Technologies Inc, an employee-owned world leader in the development and manufacture of monitoring instrumentation and software for occupational and environmental health & safety (OEHS) applications, today announced that it’s QUESTemp° Series and Metrosonics model HS-32 Portable Heat Stress Monitors have been independently tested and certified by KEMA Quality B.V. of The Netherlands to meet the requirements of ATEX Directive 94/9/EC. The QUESTemp° Series and HS-32 monitors are used to evaluate indoor and outdoor environmental conditions for the potential to cause heat stress or heat-related injuries or illnesses. In addition to industrial & service industry workers, first responders to bioterrorism are very susceptible to heat stress as a result of the chemical protective clothing they must wear. Quest is the first and only company to achieve certification of heat stress monitors, sometimes referred to as WBGT meters, to the new ATEX requirements. The ATEX approvals are in addition to existing ETL approvals for intrinsic safety. The ATEX directive has been adopted by the European Union (EU) to facilitate free trade in the EU by aligning the technical and legal requirements in the Member States for products intended for use in potentially explosive atmospheres. The Directive covers electrical and mechanical equipment and protective systems, which may be used in potentially explosive atmospheres (flammable gases, vapors or dusts.) Since July 1, 2003, it has been necessary for all products placed on the market or put into use within the EU to comply with the ATEX Directive.

“This is the second time in less than a year that we have been first to market with products meeting the new ATEX Directive,” said Dan Webster, CEO & President of Quest Technologies. Late last year we were also first to obtain certification of personal noise dosimeters to this Directive and they remain the only such products with this approval. Quest has always made it a priority that our products meet applicable international standards for performance and safety. It seems contradictory to us for users to spend dollars on products for worker safety that are not themselves confirmed inherently safe. So wherever possible, we make sure our customers have access to certified safe products.”

The QUESTemp° Series and HS-32 monitor will be on display at numerous trade shows this year around the world. See our Events page for a complete tradeshow listing.

Second Quest & Metrosonics® Calibration Laboratory Receives Independent Accreditation.

Press Release, Oconomowoc, WI, April 21, 2004

Both authorized U.S. service centers now meet requirements of ISO 17025 and ANSI Cal Lab Standards

Quest Technologies Inc, an employee-owned world leader in the development and manufacture of monitoring instrumentation and software for occupational and environmental health & safety (OEHS) applications, today announced their Rochester (NY) Technical Center (RTC) was accredited by the American Association for Laboratory Accreditation (A2LA) on April 13, 2004 for technical competence in the field of calibration. RTC was determined to meet the requirements of ISO/IEC 17025-1999 “General Requirements for the Competence of Testing and Calibration Laboratories” and ANSI/NCSL Z540-1-1994 “Calibration Laboratories and Measuring and Test Equipment – General Requirements”.

“Our industry is plagued by opportunistic companies lacking the training, competencies and credentials to provide calibration services. Independent customer satisfaction surveys indicate our customers choose Quest, in large part, because of the high quality and reliability of our products. It goes hand-in-hand that high quality products should be supported by high quality services. Our customers spend substantial dollars each year collecting and analyzing exposure data using our products. That data is used to protect the lives of workers and control the liabilities of employers. That data can only be as meaningful as it accurate, and claims of accuracy must be traceable to standards that are meaningful. This accreditation confirms that customers using our service centers for calibration will have the traceability they need,” said Dan Webster, CEO & President of Quest Technologies.

Accredited calibration services are now available from Quest at their Oconomowoc, WI and Rochester, NY facilities. Calibrations can be arranged on-line or by phone.

Quest & Metrosonics® Noise Dosimeters Receive MSHA Intrinsic Safety Approval.

Press Release, Oconomowoc, WI, April 21, 2004

First Dosimeters in World to Incorporate Exposure Alarms -- Enables Administrative Control When Engineering Controls Are Not Feasible.

Quest Technologies Inc, an employee-owned world leader in the development and manufacture of monitoring instrumentation and software for occupational and environmental health & safety (OEHS) applications, today announced that it’s NoisePro™ Series and Metrosonics model db-4000EZ Noise Dosimeters have been independently tested and certified by the Mine Safety & Health Administration (MSHA) to meet the requirements of Title 30 Code of Federal Regulations, Part 18 and are approved as permissible for use in gassy underground mines. The NoisePro Series and db-4000EZ monitors are used to evaluate worker exposure to harmful noise levels. Prior to the introduction of these new monitors in October 2003, noise dosimeters were limited to measuring and reporting accumulated noise exposure levels. Within the mining industry, feasible engineering controls are often not available or cost prohibitive. By incorporating visual and tactile alarms into these new MSHA-Approved dosimeters, mine operators are afforded a whole new method for controlling noise exposures and hearing loss. Quest is the first and only company to manufacture MHSA-approved noise dosimeters capable of telling a miner when they need hearing protection and when they have reached their daily exposure limit. This capability allows mine operators to apply administrative controls in applications where engineering controls are impractical.

“We have enjoyed a long and successful relationship with the U.S. Mining industry, both at the enforcement level and with the mine operators. We are excited to be able to bring to them some innovative technology that is supportive of both MSHA’s mission and the mine operator’s needs,” said Dan Webster, CEO & President of Quest Technologies.

The NoisePro Series and db-4000EZ dosimeters will be on display at numerous trade shows around the world. See our Events page for a complete tradeshow listing.

November 2003

Oconomowoc, Wisconsin (November 2003) – Effective July 1, 2003 many electronic safety and industrial hygiene instruments such as noise dosimeters, sound level meters, gas detectors and other electronic safety instrumentation were required to meet newer, more stringent requirements in order to be approved for use in hazardous or potentially hazardous environments within the member countries of the European Union. These new requirements were enacted under the ATEX Directive. The ATEX Directive voids all previously granted Ex and Eex approvals, requiring manufacturers to resubmit their products for testing and re-approval to the new standards in order to continue to claim intrinsically safe operation. Changes in the intrinsic safety performance standards are significant enough that many manufacturers are finding it necessary to modify or redesign their products to meet the new requirements.

Quest Technologies announced today that the new NoiseProTM Series of Quest dosimeters and db-4000EZ Metrosonics dosimeters, which they introduced at AIHce 2003 in the United States, are the first noise dosimeters in the world to be granted intrinsic safety approvals in accordance with the ATEX Directive. Simultaneously, the company received Underwriters Laboratories (UL) approval in accordance with U.S. and Canada intrinsic safety requirements. Details on both the Quest brand NoisePro Series and the Metrosonics brand db-4000EZ can be accessed through the company's corporate web site portal located at http://www.Quest-Technologies.com.
