DIESEL EXHAUST SMOKE/VOC SENSOR MODEL TOX-VOC

TYPICAL INSTALLATIONS:

•••• Bus Garages • Vehicle Maintenance & Storage

•••• Fire Stations Highway Departments

•••• Tunnels Utilities

•••• Truck Warehouses Public Works

•••• Welding Shops

GENERAL DESCRIPTION:

The model TOX-VOC diesel smoke full spectrum sensor is designed
to interface with Toxalert International’s TOX series control units.
The TOX-VOC is a microprocessor-based air quality sensor utilizing
metal-oxide semi conductor technology. This is a full spectrum sensor
sensitive to a wide variety of air pollutants such as smoke,
hydrocarbons, gasoline fumes, acetone, toluene, etc. (see Table 3).
The TOX-VOC indicates its status with indicators for auto-power
on and processor normal, ok, low, mid or high for level of
contaminant detected.

SHEET

BACKGROUND:

The diesel engine exhausts a great percentage of smoke (soot) as
well as, many hydrocarbons (e.g., ethylene, formaldehyde, methane,
benzene, and polynuclear aromatic hydrocarbons) and toxic gases
(e.g., nitric oxide, nitrogen dioxide and oxides of sulfur). The smoke
is particularly evident at the beginning of a work shift, when all
the buses or tracks are started in a maintenance/storage facility.
Even though, the exhaust smoke is not classified as a toxic, it is considered a carcinogen (reference:
carcinogenic effects of exposure to diesel exhaust - NIOSH Publication No. 88-116). Therefore many facility
owners are monitoring the smoke/hydrocarbons (VOC) as well as, the toxic oxides of nitrogen.
