Gas Monitor Calibration & Safety Equipment

Gas Monitoring, Confined Space Compliance & Respiratory Protection for Fumigators

Accurate gas monitoring and proper respiratory protection are regulatory requirements and life-safety essentials. During fumigation, monitoring verifies lethal concentration while a structure or commodity is under gas, and again during aeration and re-entry. FSS provides professional gas monitor calibration, repair, and respiratory safety equipment for fumigators, grain elevators, and industrial safety managers throughout the Midwest.

As fumigators ourselves, we use this equipment daily. FSS supports crews with calibration, recurring service, and the right respiratory protection, backed by one of the highest concentrations of certified entomologists in the industry.

Fumigation Monitoring: Label Compliance & Worker Safety

EPA fumigant labels require gas-concentration verification during exposure. Without accurate monitoring, lethal concentrations cannot be confirmed, treatment efficacy may be compromised, and worker safety and regulatory compliance are at risk. Common monitored gases include phosphine, oxygen, carbon monoxide, hydrogen sulfide, nitrogen dioxide, and sulfur dioxide.

Confined Space Monitoring & Calibration Services

Grain bins, silos, railcars, tankers, and enclosed process areas demand reliable multi-gas detection.

  • Calibration of Drager and most MSA monitors
  • Routine recurring calibration programs
  • Pre-use bump-testing support
  • Sensor replacement and calibration gas support
  • Select repair services

We keep you aligned with manufacturer recommendations, OSHA confined space standards, and fumigant label requirements, because proper calibration protects your crew and your liability.

Multi-Gas Monitors

The Drager X-am 5000 is a rugged, field-proven multi-gas monitor configurable for up to five gases, with reliable electrochemical sensors customizable for phosphine and other fumigants. We help configure the right sensor package for grain fumigation or confined-space entry.

Respiratory Protection & SCBA

When concentrations exceed exposure limits, air-purifying respirators or SCBA are required. FSS supplies the Drager X-plore 6300 full-face respirator and the PH/CN/CS/P100 phosphine canister, plus Drager PAS Lite SCBA kits for high-concentration environments, such as phosphine above 15 ppm, sulfuryl fluoride above 1 ppm, or methyl bromide above 5 ppm.

Gases We Monitor

EPA fumigant labels require gas-concentration verification during the exposure phase. Without accurate monitoring, lethal concentrations cannot be confirmed, efficacy may be compromised, and worker safety and compliance may be jeopardized. Common fumigation and confined-space gases include:

Phosphine (PH₃)Oxygen (O₂)Carbon Monoxide (CO)Hydrogen Sulfide (H₂S)Nitrogen Dioxide (NO₂)Sulfur Dioxide (SO₂)

Frequently Asked Questions

Why do gas monitors need regular calibration?

Sensors drift over time, so a monitor can read inaccurately and put people at risk. Regular calibration keeps phosphine and safety monitors reading true for compliant, safe fumigation work.

How often should monitors be calibrated?

Follow the manufacturer interval and your safety program, commonly a bump test before use and a full calibration on a set schedule. We can help you build the right calibration cadence.

Which monitors and gases do you service?

We calibrate and service the gas monitors used in fumigation and confined-space work, including phosphine detection, according to manufacturer specifications.

Do you offer loaner or rental monitors during service?

In many cases yes, so your operation stays covered while units are being serviced. Ask us about loaner and rental options.
