Paint and solvent-handling manufacturing facilities require a specific thermography precaution most other facility types don’t: any hazardous-area (classified zone) electrical inspection, including the infrared camera itself, must use intrinsically safe or explosion-proof rated equipment in zones with flammable solvent vapour present, since a standard thermal imaging camera is itself a potential ignition source in that atmosphere.
IS 15656 hazardous area classification requirements apply to paint manufacturing’s solvent storage and mixing areas, and the Institution of Engineers India has noted that facilities sometimes commission general (non-intrinsically-safe) thermography surveys that skip classified zones entirely for this reason, leaving exactly the highest-consequence areas of the plant unscanned, a gap that undermines much of the survey’s protective value even when the rest of the facility is thoroughly covered.
In a thermography survey Elion completed for a paint manufacturer in Kanpur, Uttar Pradesh, intrinsically safe equipment was used to scan the solvent mixing and storage zones alongside standard scanning of the general production and utility areas, and a connection point above the NFPA 70B priority threshold was identified on a panel feeding the mixing area, outside the classified zone itself. Corrective tightening was estimated at under ₹70,000.
For any facility handling flammable solvents, Elion recommends explicitly confirming with the thermography provider, before the survey, that classified zones will be scanned using appropriately rated equipment rather than skipped — a general commercial thermography quote that doesn’t specify intrinsically safe equipment for hazardous areas is very likely excluding exactly the zones where a hotspot finding would matter most.
Paint and solvent-handling plants need intrinsically safe thermography cameras in classified (flammable vapour) zones — a standard camera is itself an ignition risk there. Facilities should confirm before the survey that classified zones will actually be scanned, not skipped.

FAQs
Q1: Why does paint plant thermography need intrinsically safe cameras?
Paint plants may handle flammable solvents and generate potentially hazardous atmospheres. In classified hazardous areas, electrical and electronic equipment used for inspection must be suitable for the applicable hazardous-area classification. An intrinsically safe or appropriately certified thermal imaging camera helps prevent the inspection equipment itself from becoming an ignition source. The exact certification required depends on the classified zone, gas/vapour group, and temperature class.
Q2: What is the cost of a thermography survey for a solvent-handling manufacturing plant?
The cost depends on the plant size, number of electrical assets, hazardous-area classification, number of scanning points, accessibility, camera certification requirements, operating conditions, and reporting scope. Because classified-area thermography may require specialized equipment and competent personnel, it can cost more than a conventional electrical thermography survey. A site-specific quotation is therefore preferable to a fixed rate.
Q3: What is hazardous area classification for paint manufacturing?
Hazardous-area classification identifies locations where flammable gases or vapours may be present in concentrations that could create an explosion hazard. Paint manufacturing may have classified areas around solvent storage, mixing and processing equipment, filling areas, vents, pumps, and other potential release sources. The classification and zone extent depend on the substances handled, release sources, ventilation, operating conditions, and applicable standards.
Q4: How can I confirm a thermography provider will scan classified zones?
Before awarding the survey, ask the provider to confirm in writing that they can safely inspect the specified hazardous zones. Check the thermal camera’s hazardous-area certification, including the applicable zone, gas/vapour group and temperature class, and verify that the certification is valid for the intended environment. Also confirm that the thermographers are trained and competent to work under the site’s hazardous-area procedures and permit-to-work requirements.
Q5: What happens if classified zones are skipped during a thermography survey?
Skipping classified zones can leave critical electrical equipment and connections uninspected, potentially allowing overheating or developing faults to remain undetected. It also creates a gap in the survey’s coverage and may undermine the purpose of the condition-monitoring programme. Classified areas should not simply be omitted because they are hazardous; they should be assessed using equipment and procedures appropriate for the area’s classification.
