SAFETY & COMPLIANCE
CTI Service is your gas detection compliance companion. Every member of our team knows the industry standards and best practices that keep your system compliant and performing as expected.
In accordance with IIAR 6, our field service technicians are scheduled to visit facilities refrigerated with ammonia every 6 months to calibrate toxic gas sensors and perform an annual test of alarm, ventilation and shutdown outputs. Our team is also trained to service and provide safety assessments for gas detection systems monitoring CO2, CO, NO2 and synthetic refrigerants like Freon, with a recommended calibration frequency of every 6 months.

Compliance Without the Complexity
Your Facility’s Safety is our Top Priority.
CTI Service team members complete extensive technical and compliance training to help you prevent costly compliance surprises, reduce downtime, and provide confidence that your facility is properly equipped while minimizing gas detector repair costs.
Advanced Appointment Scheduling & Upcoming Calibration Reminders.
We understand you have a lot on your plate, which is why CTI’s service schedulers send timely calibration reminders to ensure your gas detector maintenance remains aligned with current industry standards.
Annual Functional Output Testing of Shutdowns, Ventilation and Alarms.
Proper calibration confirms your sensors are reading accurately, but it doesn’t confirm your system meets current standards. CTI field technicians can evaluate your whole system and identify gaps most providers aren’t trained to look for.
Secure and Accessible OSHA Documentation.
All service records and compliance documents are securely stored on CTI servers and are readily available when needed.

Audit-Ready Documentation
Documentation is just as important as the service itself. CTI provides detailed PSM reports that verify system performance and support your compliance efforts.
All service documentation is securely stored on CTI servers, giving your facility easy access to critical inspection, calibration, and maintenance records when they’re needed most.
Each audit-ready PSM report is completed by the CTI Technician who performed the work and reviewed by PSM documentation experts for accuracy before delivery. Built to support OSHA PSM Standard 1910.119(j)(v)(iv), CTI documentation helps demonstrate compliance, verify system reliability, and support the ongoing safety of your facility.
