Hydrazine Dual Level SafeAir Badge (382020-50)

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.

Quantity = 50 badges  *clips are NOT included*

Hydrazine Information

$248.25

Color change for Hydrazine Dual Level is from orange to maroon.

The SafeAir Hydrazine badge may be used for personnel or area monitoring for exposure times ranging from 5 minutes to 2 consecutive days.

For better determination of hydrazine concentrations at relative humidities greater than 55%, it is recommended that the results obtained from reading the badge be multiplied by a correction factor of 1.13 for every 10% RH greater than 55%.

Introduction

Hydrazine is a colorless liquid with a penetrating odor resembling that of ammonia. It is extremely destructive to the tissues of the mucous membranes and upper respiratory tract. Symptoms of exposure may include coughing, shortness of breath, wheezing, laryngitis, headache, nausea and vomiting. OSHA exposure limit for hydrazine is 1 ppm (TWA). NIOSH exposure limit for hydrazine is 0.03 ppm (2 hour ceiling). NIOSH recommends that hydrazine be handled as a potential occupational carcinogen in the workplace.

Hydrazine is used predominantly as a fuel for rocket and jet engines and in the manufacturing of pharmaceuticals. Hydrazine salts are used in refining and as corrosion inhibitors.

Principle of Operation

The SafeAir hydrazine dual level badge is a monitoring system designed to indicate the presence of hydrazine at concentrations below the permissible exposure limit. The SafeAir hydrazine dual level badge detects the presence of hydrazine by forming a color change in the shape of a half triangle. This indication is produced by a color-forming reaction which occurs when hydrazine reacts with a flat indicator layer. A color change may appear on the front and/or the back side of the badge, depending upon the exposure dose.

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 half triangle will change color when hydrazine is present. Please note that the color change will appear underneath the printed exposure dose (sensitivity).

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

Storage

The ChromAir hydrazine dual level monitor should be refrigerated in its sealed bag at all times.
