Hazardous Locations (HazLoc) are among the most demanding work environments in industrial operations. Defined by the presence of flammable gases, vapors, dust, or fibers, these zones require strict adherence to safety protocols and the use of certified equipment.
For frontline workers, the challenge is not only environmental risk but also the need to maintain productivity, accuracy, and compliance under pressure.
Mobile technology has become a cornerstone of modern field operations, enabling real-time data access, digital inspections, and remote collaboration. However, in HazLoc environments, standard consumer devices are insufficient. Rugged, certified solutions are essential to ensure safety, reduce downtime, and support uninterrupted workflows.
This blog explores how rugged mobility solutions, specifically those certified for HazLoc use, enhance operational efficiency, protect workers, and align with regulatory standards.
Through data-driven insights and practical examples, we’ll examine the real-world impact of rugged devices on industrial productivity and safety.
1. HazLoc Classifications and Regulatory Context
Hazardous Locations (HazLoc) are defined by the presence of flammable gases, vapors, dust, or fibers that pose a risk of ignition. These environments are regulated by standards such as:
OSHA 1910.307: Defines hazardous locations and outlines requirements for electrical equipment and wiring in areas where flammable or combustible substances may be present.
NFPA 70 (National Electrical Code): Chapter 5 addresses wiring and equipment standards for hazardous locations, enforced across all 50 U.S. states.
🔍 HazLoc Classification Breakdown
| Class | Division | Hazard Type | Typical Industries |
|---|---|---|---|
| Class I | Division 1 | Flammable gases or vapors present continuously or frequently | Oil & Gas, Chemical Plants |
| Class I | Division 2 | Flammable gases or vapors present only under abnormal conditions | Refineries, Storage Facilities |
| Class II | Division 1 | Combustible dust present continuously or frequently | Grain Handling, Metal Processing |
| Class II | Division 2 | Combustible dust present only under abnormal conditions | Food Processing, Pharmaceuticals |
| Class III | Division 1 | Ignitable fibers or flyings present during normal operations | Textile Mills, Woodworking |
| Class III | Division 2 | Ignitable fibers or flyings present only under abnormal conditions | Furniture Manufacturing |

✅ Why It Matters for Mobile Technology
Devices used in HazLoc zones must be:
- Certified for the specific class and division
- Intrinsically safe or explosion-proof
- Tested for environmental durability
Failure to comply can result in:
- Regulatory fines
- Equipment damage
- Worker injury
2. Rugged Certifications That Matter in HazLoc Workflows
In hazardous environments, mobile devices must do more than function—they must survive. Certifications like MIL-STD-810H and IP68 are critical indicators of a device’s ability to withstand the physical and environmental stressors common in HazLoc zones.
🔐 MIL-STD-810H: Military-Grade Durability
MIL-STD-810H is a U.S. Department of Defense standard that outlines testing procedures for environmental resilience. Devices certified under this standard are tested across 29 categories, including:
| Test Type | Purpose |
|---|---|
| Shock & Vibration | Simulates drops, transport, and use |
| High/Low Temperature | Ensures operation in extreme climates |
| Humidity | Tests resistance to moisture buildup |
| Sand & Dust | Validates sealing against particles |
| Altitude | Assesses performance in low pressure |
📊 Data Point:
Devices with MIL-STD-810H certification can withstand drops from up to 4 feet, operate in temperatures ranging from -20°C to 60°C, and resist vibration from heavy machinery.

💧 IP68: Ingress Protection for Dust and Water
IP68 is part of the IEC 60529 standard, which defines levels of protection against solids and liquids.
| Digit | Meaning |
|---|---|
| 6 | Complete protection against dust |
| 8 | Protection against immersion in water (up to 1.5m for 30 minutes) |
📊 Data Point:
IP68-rated devices are 100% dust-tight and can be submerged in water without damage, making them ideal for outdoor, wet, or particulate-heavy environments.

✅ Why These Certifications Matter in HazLoc Workflows
Field workers in HazLoc zones face unpredictable conditions. Certified rugged devices:
- Reduce downtime due to environmental damage
- Ensure compliance with safety standards
- Enable uninterrupted workflows in extreme conditions
- Protect data integrity during inspections and reporting
These certifications are essential for safe, reliable, and efficient operations in hazardous industries.
3. Workflow Benefits and Productivity Impact for Frontline Teams
In hazardous environments, productivity and safety are tightly linked. Rugged mobile solutions—when properly certified and integrated—can significantly improve how frontline teams operate, communicate, and respond to dynamic field conditions.
📈 Key Workflow Benefits
1. Reduced Downtime
- 30–50% fewer device failures reported when using rugged tablets compared to consumer-grade devices in industrial settings.
- Fewer failures mean less time spent on repairs, replacements, and reboots.
2. Faster Inspections and Reporting
- Digital forms and real-time data capture reduce manual paperwork.
- Field workers can submit reports instantly, improving decision-making speed.
3. Improved Safety Compliance
- Devices certified for HazLoc use reduce the risk of ignition.
- Built-in checklists and alerts help teams follow safety protocols consistently.
4. Enhanced Mobility and Ergonomics
- Features like rotating hand straps, kickstands, and shoulder mounts allow comfortable use in PPE and confined spaces.
- Workers can operate devices hands-free while climbing, inspecting, or handling tools.
5. Real-Time Collaboration
- Secure connectivity enables instant communication with remote teams, supervisors, or control centers.
- Reduces delays in troubleshooting, approvals, and emergency response.
Conclusion
Hazardous locations demand more than rugged hardware, they require mobile solutions that are certified, durable, and designed to support real-world workflows. From reducing downtime and improving safety compliance to enabling real-time data access and collaboration, rugged mobility tools have become essential for frontline teams operating in high-risk environments.
By aligning with standards like MIL-STD-810H, IP68, and Hazardous Location classifications, organizations can ensure their mobile deployments are not only resilient but also compliant with regulatory frameworks such as OSHA 1910.307 and NFPA 70.
