Eco-Friendly Salt Spray Chambers: Use Non-Toxic Salt Solutions for Testing

For teams in oil & gas, mining, chemical processing, and offshore energy, corrosion testing faces a unique, non-negotiable challenge: safety. Traditional salt spray testers lack explosion-proof (Ex) certification, making them unsafe to use in hazardous zones—such as oil platforms, chemical plant floors, or underground mines—where flammable gases, vapors, or dust are present. This forces teams to ship specimens to remote labs for testing, adding weeks of delay, increasing logistics costs, and creating a disconnect between on-site production issues and corrosion data. The ExShield Pro Explosion-Proof Salt Spray Tester, launched by TOBO GROUP (a leader in safety-focused industrial testing solutions), solves this by combining ASTM-compliant corrosion testing with rigorous explosion-proof design, letting teams run tests on-site in high-risk environments while meeting global safety standards like ATEX, IECEx, and NEC Class I Division 1.
The core of the ExShield Pro’s value is its ATEX Zone 1 / IECEx Ex d IIC T4 Ga-certified construction, engineered to eliminate ignition risks in environments with flammable hydrocarbons (e.g., oil vapors) or combustible dust (e.g., mining byproducts). Every component is built for hazard resistance: the chamber uses 316L stainless steel with a flameproof (Ex d) enclosure, designed to contain and cool any internal spark or flame before it can ignite external gases; internal electrical parts (sensors, heaters, fog generators) are sealed in intrinsic safety (Ex ia) modules, limiting electrical energy to levels too low to spark combustion; even user interfaces are protected, with a 10-inch touchscreen rated IP66 for dust/water resistance and non-sparking buttons, while all cables use explosion-proof glands to prevent gas ingress. An offshore oil platform operator previously shipped pipe corrosion specimens to a shore-based lab—taking 3 weeks to get results and delaying maintenance decisions—but with the ExShield Pro, they now run 72-hour salt spray tests directly on the platform (a Zone 1 hazardous area), cutting turnaround time to 3 days. “We used to wait weeks to confirm if a pipe’s coating was holding up,” says their maintenance manager. “Now we test on-site and fix issues before they become leaks.”
High-risk industries don’t just need safe testers—they need tools that simplify compliance with strict standards like OSHA Process Safety Management, API 5L for oil pipelines, and ISO 80079-36 for explosive atmospheres—and the ExShield Pro’s Regulatory Compliance Suite eliminates manual paperwork and reduces audit risks to address this. The suite automatically logs every test detail (timestamp, operator ID, salt concentration, temperature, safety status) in a tamper-proof digital record—required for OSHA and API audits—generates pre-built compliance reports that map test data to specific standards (e.g., “API 5L Corrosion Validation for Carbon Steel Pipes”) with one click (no manual formatting needed), and stores 5+ years of data locally (encrypted) and in the cloud (GDPR/CCPA-compliant), ensuring auditors can access historical records instantly. A chemical manufacturer in Texas used this suite to pass an OSHA audit with zero findings: “Before, we spent 40 hours a month compiling handwritten test logs,” says their EHS manager. “The ExShield Pro auto-generates reports, and we just export them for auditors. It’s eliminated compliance stress.”
The gap between the ExShield Pro and traditional salt spray testers is stark: traditional models have no explosion-proof certification and are unsafe in hazardous zones, while the ExShield Pro meets ATEX Zone 1, IECEx, and NEC Class I Division 1 standards; traditional testers only have IP20 protection (dust-sensitive, no water resistance) compared to the ExShield Pro’s IP65 rating; traditional setups require remote lab testing with 2–4 week delays, but the ExShield Pro enables on-site testing with results in 2–3 days; traditional testers rely on error-prone manual logging that raises audit risks, while the ExShield Pro automates logs and generates compliance reports; and traditional testers only work in 15°C–40°C, whereas the ExShield Pro handles -10°C to 50°C for harsh conditions.
“For oil, mining, and chemical teams, ‘safe’ and ‘fast’ shouldn’t be trade-offs,” says TOBO GROUP’s Industrial Safety Testing Director. “The ExShield Pro lets them test where the work happens—on-site, in hazardous zones—without compromising safety or compliance. It’s not just a tester; it’s a way to keep production moving and teams safe.”
