Top MSA Safety Products

PK Safety offers a wide selection of MSA’s most trusted safety solutions to help workers detect atmospheric hazards, stay compliant, and operate confidently in high-risk environments.

Here’s an overview of some popular safety equipment:

MSA ALTAIR H2S Gas Detector

The MSA ALTAIR H2S Gas Detector is a single-gas monitor designed for industrial applications where hydrogen sulfide exposure is a risk. It offers two years of continuous H2S monitoring without the need for sensor or battery replacement. The device comes factory-calibrated and only requires periodic bump tests to ensure continued accuracy and compliance.

Coming at an accessible price point, the MSA ALTAIR H2S is a cost-effective H2S monitoring solution ideal for workers in oil and gas, wastewater, and chemical processing.

MSA ALTAIR 4XR Multigas Detector

The MSA ALTAIR 4XR Multigas Detector features MSA's advanced XCell sensors that deliver industry-leading response times, detecting gases twice as fast as the industry average. This technology also provides shorter span calibration times (typically 60 seconds), less gas usage for bump tests (under 15 seconds), and an extended typical sensor life of up to four years.

Built to withstand exceptionally harsh conditions, the ALTAIR 4XR is IP68 rated (dustproof and waterproof, submersible up to 2 meters for 60 minutes) and has been tested to survive multiple incidental drops from an industry-leading 25 feet (7.5 meters) onto concrete.

MSA ALTAIR 5X Multigas Detector Kit

The MSA ALTAIR 5X Multigas Detector is a highly versatile and durable instrument capable of detecting up to six gases simultaneously. In addition to combustible gases (LEL), oxygen (O2), carbon monoxide (CO), and hydrogen sulfide (H2S), the ALTAIR 5X is compatible with PID and infrared sensors for VOCs and CO2 detection. It also integrates seamlessly with the Galaxy® GX2 test system for automatic calibration and data management.

This kit includes the MSA 5 gas detector with LEL, O2, CO, and H2S XCell sensors, a 10’ sampling line, and a 1’ probe. There is an option of a standard mono or a deluxe-colored display screen.

MSA Galaxy GX2 Test Stand for ALTAIR 5X

The MSA Galaxy GX2 automates calibration and testing for MSA ALTAIR 5X Gas Detectors to streamline critical maintenance routines and ensure workers have ready-to-use protection from atmospheric hazards. The GALAXY GX2 comes with pre-configured plugs, barbs, fresh air filter, power supply with corresponding plug, spare parts kit (gas tubing, barbs, and plugs), Ethernet cable (short cable for connection between test stands), screen protector, and QuickStart Guide.

When used with MSA Link™ Pro Software, the GALAXY GX2 system offers advanced data management capabilities that automatically log test results, calibration data, and instrument information. It can also facilitate report generation, fleet management, exposure tracking, and proactive safety program adjustments.

MSA Workman CSE Kit  with Tripod, Rescuer, and Winch

The MSA Workman CSE Kit is a comprehensive safety solution designed for vertical entry and rescue operations in confined spaces such as manholes, tanks, and underground vaults. This kit includes a durable aluminum tripod, a 50-ft Workman Rescuer, and a 65-ft Workman Winch, providing a secure and efficient system for lifting and lowering personnel and materials during non-entry rescue operations. 

Whether for routine maintenance or emergency response, the MSA Workman CSE Kit delivers trusted performance and compliance, making it a go-to solution for confined space safety.

Frequently Asked Questions

What does MSA Safety make?

MSA Safety manufactures a wide range of safety products designed to protect workers in high-risk environments. Their product lineup includes gas detection instruments, respiratory protection (such as SCBAs and face masks), fall protection equipment, head protection (hard hats and helmets), thermal imaging cameras, and confined space entry kits. These products are widely used across industries like oil and gas, construction, mining, fire service, and utilities.

How do you bump test an MSA gas detector?

The easiest way to perform a bump test is by using the MSA Galaxy® GX2 automated test system, which handles the process with minimal user input. For manual testing, apply the test gas using a regulator and tubing, then observe that the detector’s audible, visual, and vibrating alarms activate correctly. Always follow the manufacturer’s bump test procedure for your MSA detector model.

Does MSA offer warranties for its products?

Yes, MSA Safety offers warranties on many of its products, with coverage varying by product type and model. For example, MSA ALTAIR gas detectors typically come with warranties ranging from two to four years, depending on the sensor configuration. Warranty terms cover defects in materials and workmanship under normal use and service. For exact warranty details, it’s best to consult the product documentation or contact MSA or an authorized distributor like PK Safety.
