Msa Safety 10076729 Single-gas Hcn Detector

Product Description

The MSA SAFETY 10076729 is a portable single-gas detector designed to monitor hydrogen cyanide (HCN) concentrations in the work environment. Built around a lithium battery and an LCD display, this clip-style personal gas monitor alerts the wearer through three simultaneous alarm modes: audible at 95 dB, visible indicator, and vibration. The detection range runs from 0 to 30 ppm, with preset alarm thresholds at 4.7 ppm and 10 ppm. It is sized for all-day wear at 3.4 inches tall, 2 inches wide, and 1 inch deep. Industrial hygienists, safety officers, and confined-space entry teams rely on this unit for continuous personal exposure monitoring.

This detector is suited for industrial environments where hydrogen cyanide exposure is a recognized hazard, including metal finishing, chemical processing, and confined-space operations. Its compact form factor makes it practical for workers who need continuous personal monitoring throughout a shift without carrying bulky equipment. The operating temperature range of -20 to 50 degrees C allows deployment in cold-storage areas, outdoor worksites, and process facilities with elevated ambient temperatures.

Key Features

• Monitors hydrogen cyanide from 0 to 30 ppm
• Dual alarm set points at 4.7 ppm and 10 ppm for TWA and STEL thresholds
• Triple alarm notification: 95 dB audible, visual indicator, and vibration
• LCD display provides real-time gas concentration readout
• Lithium battery for extended service life between replacements
• Compact body at 3.4 x 2 x 1 inches for comfortable all-day clip wear

Compatibility

Designed as an OEM personal gas monitor for use in single-gas HCN monitoring applications; consult MSA SAFETY documentation for compatible calibration gas, bump-test equipment, and docking station accessories.

Installation Notes

This detector is a personal worn device and does not require fixed installation; however, setup and calibration should be performed by a qualified safety professional following the manufacturer's instructions and applicable OSHA confined-space entry requirements. Before placing the unit in service, perform a bump test to confirm sensor response and alarm function. Do not expose the sensor to cleaning solvents or paint aerosols, as these can degrade sensor accuracy or cause false alarms.
