The Mercury SafeAir Badge is a visual chemical detection badge designed to provide a quick, reliable indication of hazardous mercury vapor levels in the workplace. When mercury is present, a color-changing exclamation mark appears on the badge — changing from white to purple — alerting you to potential danger before exposure becomes harmful.
This badge is ideal for personal or area monitoring and can be used for exposure times from 15 minutes to 48 hours.
Why Monitor for Mercury?
Mercury is a silver-white, heavy, mobile liquid metal with no distinctive odor, making it difficult to detect without proper monitoring. It can be absorbed through the skin, respiratory tract, and gastrointestinal tract.
Chronic exposure to mercury can lead to:
- Inflammation of the mouth and gums
- Kidney damage
- Muscle tremors
- Depression
- Nervousness
Mercury spills or heated mercury vapors are particularly hazardous.
Exposure Limit: OSHA and NIOSH set the ceiling exposure limit for mercury vapor at 0.1 mg/m³.
Where Mercury is Found
Mercury is commonly used in:
- Barometers, thermometers, hydrometers, pyrometers
- Mercury arc lamps producing ultraviolet light
- Pharmaceuticals and agricultural chemicals
- Antifouling paints
How the Mercury SafeAir Badge Works
The SafeAir Mercury Badge is designed to detect mercury below the permissible exposure limit. When mercury vapor is present, it reacts with a special indicator layer inside the badge. This reaction produces a distinct purple exclamation mark within a triangle, giving a clear, unmistakable warning of exposure.
This color change can appear on the front, back, or both sides of the badge.
Operating Instructions
- Warm to room temperature – Remove the pouch from refrigeration and allow the badge to reach ambient temperature.
- Open and attach – Remove the badge from its protective pouch. For personal monitoring, attach near the breathing zone (e.g., shirt collar) with the front side exposed.
- For area monitoring – Attach the badge to a stand in a central location, front side exposed.
- Watch for color change – If mercury vapor is present, a purple exclamation mark will appear.
- Calculate average concentration – Divide the exposure dose (mg/m³∙hr) by the total exposure time (hr) for results.
Storage
For best performance, store the Mercury SafeAir Badge in its sealed pouch inside a refrigerator when not in use.

Protect Yourself from Hidden Mercury Hazards
Mercury vapor is colorless, odorless, and dangerous — and you may not know it’s there until it’s too late. The Mercury SafeAir Badge offers peace of mind and reliable detection whether you’re monitoring a workstation, laboratory, or spill site.
