The Haz-Dust IV Personal Real-Time Monitor Model HD-1004 is a completely portable package that allows true breathing zone measurements and comprehensive graph reporting. The product is designed for aerosol and dust monitoring for industrial hygiene and environmental air investigations.
The human respiratory system is divided into three regions where particulates of certain sizes or aerodynamic diameter are likely to be deposited. OSHA ( Occupational Safety and Health Administration) sets strict guidelines and methods for these different particle sizes.
An understanding of how and where particles are deposited is necessary to properly evaluate the hazards. The Haz-Dust IV has the proper size selective features for measuring the three respiratory regions that are applicable to both EPA and OSHA standards.
Three Interchangeable Sampling Inlets to Measure Health Effects on Specific Regions or the Human Lungs
The Haz-Dust IV Personal Real-Time Dust Monitor is individually worn and offers immediate determination and data storage of airborne particulate concentrations in milligrams per cubic meter ( mg/ m³ ) . The patent pending sensor design that allows the interchange of sampling heads for inhalable, thoracic and respirable separations. The in-line disposable filter cassette allows the user to simultaneously collect filter samples for further gravimetric or chemical analysis.
The signal processing electronics and microprocessor are enclosed in a compact case that attaches to the individual' s waist. A real-time display reports concentrations in milligrams per cubic meter ( mg/ m³ ) . Statistics such as TWA, STEL, Maximum and Minimum can instantly be viewed on the display. The internal user adjustable alarm can be preset to alert the user of approaching threshold limits.
The HD-1004 can be used for a variety of applications including lead, silica, welding fumes, pharmaceutical and construction dust. Accompanying software provides management ready graphs and reports. HD-1004 is an excellent OSHA survey compliance tool for determining worker exposure to airborne contaminants, evaluating levels of respiratory protections, or any application that requires immediate and accurate air monitoring of lung damaging particles.
Applications
• Determining levels of worker respiratory protections for OSHA compliance.
• Compliance program reviews.
• Evaluating work practices and controls of any dust generating practice.
• Can be combined with NIOSH video exposure monitoring for real-time graphical overlays.
• Welding fume exposures.
• Air quality studies in occupational health and industrial hygiene.
• Haz-Mat air quality investigation and waste site remediation.
The Haz-Dust IV Monitor is a useful tool for all air monitoring applications involving lung-damaging particulates.
When used as part of a routine air-monitoring program HD-1004 can significantly reduce the number of filter gravimetric tests and laboratory analysis. For example: OSHA compliance air monitoring program may dictate air monitoring for particulates on a monthly basis to determine that work practices are below Federal Regulations. If a company has 10 or more employees at risk of exposure this can result in as many as 10 to 20 tests per month and subsequent lab analysis. By implementing a HD-1004 real-time dust monitor, particulate concentrations can be determined immediately and in real-time. No special skills are needed and no laboratory analysis is required. HD-1004 actually pays for itself by reducing the number of filter gravimetric tests by 25% to 50% . HD-1004 alerts you in seconds and allows you to take immediate corrective action.
HD-1004 is a personal real-time dust monitor with an internal air sampling pump that is microprocessor controlled. This allows for large data storage and on screen statistical calculations. The detached sensor is miniaturized and easily attaches to the individual' s lapel for true breathing zone measurements.
