Color change for Carbon Monoxide is from brown to black.

The SafeAir Carbon Monoxide badge may be used for personal or area monitoring for exposure times ranging from 15 minutes to 10 hours.

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 the 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 SafeAir carbon monoxide badge is a monitoring system designed to indicate the presence of carbon monoxide at concentrations below the permissible exposure limit. The SafeAir carbon monoxide badge detects the presence of carbon monoxide by forming a color change in the shape of an exclamation mark inside the triangle. This indication is produced by a color-forming reaction which occurs when carbon monoxide reacts with a flat indicator layer.

Operating Instructions

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

2. Remove the badge from its protective pouch.

3. Remove activation label before monitoring.

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

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

6. The exclamation mark appears within the triangle when carbon monoxide is present. Please note that the exclamation mark will appear underneath the printed exposure dose (sensitivity).

7. To obtain the average concentration, divide the exposure dose (ppm-hr) by the exposure time in hours (hr).

Storage

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