HAZMAT responds to heavy industrial pollution air monitor program. The integration of video couple to measure particulate contamination allows a more dynamic assent in identifying and analyzing the air contaminant exposure. This allowing for better control and documentation for improving decision-making.
Applications
* Determining levels of worker respiratory protection for OSHA compliance
* Compliance program reviews
* Evaluating work practices and controls of any dust-generating practices
* Safety audits
* 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
* T9VDM7500 Monitor is a useful tool for all monitoring applications involving lung-damaging particulates
In addition to Occupational Health applications, the T9VDM7500 Video dust monitoring system has benefits for hazardous material remediation, fire fighters, and emergency rescues. Industrial emissions and Insurance company in video documenting any lung-damaging particulate exposure.
