Temperature & Humidity Mapping in Oman: A Complete Regulatory & Technical Guide
In the Sultanate of Oman, environmental control is not just about quality—it is a legal mandate. With the Oman Vision 2040 driving the logistics and healthcare sectors, the Ministry of Health (MOH) and the Ministry of Agriculture have tightened requirements for thermal validation.
At Westcal Calibration Lab, we specialize in ISO accredited mapping services. This guide explores how we help Omani businesses stay compliant across every governorate.
1. Regional Environmental Challenges in Oman
Mapping protocols must adapt to Oman’s diverse micro-climates. We tailor our sensor placement based on local conditions:
| Region | Climate Challenge | Critical Mapping Focus |
| Muscat & Sohar | High Coastal Humidity | Humidity (RH) mapping for medical stores & food hubs. |
| Salalah (Dhofar) | Seasonal Khareef (Fog/Cool) | Year-round stability studies for vaccine & seafood storage. |
| Nizwa & Ibri | Extreme Dry Heat (+48°C) | High-temperature “worst-case” scenario thermal mapping. |
| Duqm (Al Wusta) | Industrial Dust & Salinity | Equipment validation for modular cold rooms in port zones. |
2. Comprehensive Mapping Solutions
Our services cover the entire supply chain, ensuring OQ (Operational Qualification) and PQ (Performance Qualification):
- Warehouse Thermal Mapping: Essential for large-scale GSDP (Good Storage & Distribution Practice) compliance in Rusayl and Sohar Freezone.
- Cold Storage & Walk-in Freezers: Validating +2°C to +8°C and -20°C ranges with NIST-traceable loggers.
- Vehicle & Reefer Mapping: Documenting temperature stability for long-haul transport between Muscat and Salalah.
- Pharmacy & Lab Equipment: Specialized mapping for ultra-low freezers, incubators, and stability chambers.
3. Meeting Oman’s Regulatory Standards
To pass an audit in Oman, your mapping report must be detailed and scientifically sound. Our reports align with:
- Oman Ministry of Health (MOH): Requirements for pharmaceutical and vaccine storage.
- WHO TRS 961 & 1025: Global standards for temperature-sensitive products.
- GSDP Standards: GCC-wide Good Storage and Distribution Practices.
- ISO 17025: Ensuring the data loggers used are calibrated by an accredited laboratory.
Key Audit Tip: Most Omani regulators now look for “Summer” and “Winter” mapping cycles to account for the Sultanate’s extreme seasonal temperature variance.
4. Why Professional Mapping Matters
A simple thermometer isn’t enough. Professional mapping identifies:
- Hot & Cold Spots: Areas near loading bays or under AC vents that fluctuate.
- Power Failure Recovery: How long your stock stays safe if the power goes out.
- Door-Opening Impact: Assessing how frequent access affects internal stability.
Conclusion
Whether you are operating a logistics hub in Duqm or a clinical lab in Barka, Westcal provides the technical expertise and accredited documentation required to succeed in Oman’s competitive market.
