Chlorine SafeAir Color Comparator (383010)

The color comparator allows you to pinpoint the exposure dose of the gas when used with the standard badge.

*Does NOT come with the badge. The badge needs to be purchased additionally*

Note: we are not able to ship the badges overseas

Chlorine Information


Color change for Chlorine is from yellow to orange.

The SafeAir Chlorine badge may be used for personnel or area monitoring for exposure times ranging from 15 minute to 48 hours. For higher resolution, this color comparator can be used with the SafeAir chlorine badge (part number: 382009-50).



Chlorine is a greenish-yellow gas with a pungent, irritating odor. Generally, chlorine is a potent respiratory system irritant. Mild exposures to chlorine cause burning of eyes, nose and mouth. Exposure to concentrations as high as 1000 ppm is likely to be fatal after a few deep breaths. The OSHA PEL for chlorine is 1 ppm (ceiling), whereas the NIOSH REL is 0.5ppm (ceiling).

Chlorine is an important chemical commodity widely used in the production of safe drinking water. It is also extensively used in the production of paper products, dyestuffs, textiles, petroleum products, chlorinated solvents, etc.


Principle of Operation

The SafeAir chlorine badge is a monitoring system designed to indicate the presence of chlorine at concentrations below the permissible exposure limit. The SafeAir chlorine badge detects the presence of chlorine 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 chlorine reacts with a flat indicator layer.

 SafeAir chemical detection badges are a visual indication badge that alerts you with a color changing exclamation mark when there is a specific chemical hazard.

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. 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.

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

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

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



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