Hydrogen Sulfide Information

$165.50

Color change for Hydrogen Sulfide is from pale blue to gray.

The SafeAir Hydrogen Sulfide badge may be used for personnel or area monitoring for sampling time from 15 minutes to 48 hours.

Introduction

Hydrogen sulfide is a colorless gas with a strong odor resembling rotten eggs. Continuous exposure to low concentrations (15 - 20 ppm) generally causes irritation to the mucous membranes. It may also cause headaches and dizziness. High concentrations (200 - 300 ppm) can result in respiratory arrest leading to unconsciousness. Exposure for more than 30 minutes at concentrations as high as 700 ppm has been fatal. Continuous inhalation of low concentrations may cause loss of the sense of smell which makes the detection of its presence by odor ineffective. OSHA exposure limit for hydrogen sulfide is 20 ppm (TWA). NIOSH exposure limit for hydrogen sulfide is 10 ppm (TWA).

Hydrogen sulfide is a widely spread pollutant. It is emitted as a byproduct in many industries such as oil refineries, production of sulfuric acid, gelatin, leather,  artificial silk and sugar. As a product of normal biodegradation of bioproducts, hydrogen sulfide is spread in waste water treatment locations.

Principle of Operation

The SafeAir hydrogen sulfide badge is a monitoring system designed to indicate the presence of hydrogen sulfide at concentrations below the permissible exposure limit. The SafeAir hydrogen sulfide badge detects the presence of hydrogen sulfide 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 hydrogen sulfide 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 hydrogen sulfide 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).

Storage

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