Color change for Carbon Monoxide is from light brown dark brown/black.

The ChromAir Carbon Monoxide badge may be used for personnel or area monitoring for exposure times ranging from 5 minute to 48 hours. For higher resolution, the ChromAir carbon monoxide badge may be used in conjunction with the ChromAir carbon monoxide color comparator (part number: 384006).

Introduction

Carbon monoxide is a colorless, odorless gas. It is the only commonly used industrial gas which is both highly toxic and odorless. Symptoms of exposure to carbon monoxide include headaches, weakness dizziness, palpitations and nausea. Low levels of carbon monoxide in air, which are not immediately hazardous to life, may impair reaction time or sensory perception. Chronic exposure to low levels of carbon monoxide may adversely affect the cardiovascular system. Loss of consciousness and death may result from continued or more intense exposure. OSHA exposure limit for carbon monoxide is 50 ppm (TWA). NIOSH exposure limit for carbon monoxide is 35 ppm (TWA).

Carbon monoxide is a widely spread air pollutant. It is a byproduct in the combustion of gasoline, diesel, kerosene and coal fuel, therefore, carbon monoxide may exist in different industries, residential areas and highways.

Principle of Operation

The ChromAir passive monitor is a patented direct-read autogenic exposimeter. The device is constructed from six cells attached on one side to a flat indicator layer and on the other side to a series of different diffusive resistances. Carbon monoxide gas diffuses to the cells through the different diffusive resistances and reacts with the indicator layer, producing color change from light brown to brown to black. The color produced on the indicator layer is a direct measure of the exposure dose. Visual color comparison is achieved by observing the formation of the brown threshold color on the individual cell and reading the corresponding exposure dose.

Direct Read Color Comparator Safety Monitor

Pictured above is the additional color comparator that is used for higher resolutions and accuracy (available for Carbon Monoxide, Formaldehyde, Mercury).

Operating Instructions

1. Remove the pouch from refrigerator and allow it to warm to room temperature.

2. Remove the badge from its protective pouch.

3. Enter all pertinent information on the I.D. label before monitoring is started (i.e. name, location, date and start time).

4. Prior to exposure, remove the protective strip from the first cell on the front of the badge.

5. For personnel monitoring, attach the badge near the user's breathing zone (i.e. collar) with the front side exposed to the surrounding atmosphere.

6. For area monitoring, attach the badge to a stand and mount in a centralized area with the front side exposed to the surrounding atmosphere.

7. Check the back side of the badge periodically to determine the exposure dose (ppm•hr).

8. To read the badge, locate the highest level cell with brown threshold color.

9. To obtain the average concentration (ppm) in the surrounding atmosphere, divide the exposure dose (ppm•hr) by the exposure time in hours.

EXAMPLE: If the sampling time is 2 hours and the badge reads 10 ppm•hr, the average conc

Storage

The ChromAir carbon monoxide monitor should be refrigerated in its sealed bag at all times.
