A rugged case, an IP rating and a drop-test report do not establish that a handheld may be used in a classified hazardous area. Start with the facility’s documented area classification and the applicable local approval route. Then verify the exact orderable device, its marking, certificate status and permitted operating configuration—including battery and accessories—against that location. If any of those facts is missing, hold the purchase decision for the site’s qualified safety authority rather than treating “rugged” or “intrinsically safe” in a listing as sufficient evidence.
This is a procurement and acceptance guide, not a certification claim for an AIDC GO model or a substitute for site engineering approval. The IP and drop-test guide addresses environmental durability; this article addresses whether a specific electrical device configuration is suitable for a classified location.
Define the location before comparing devices
Ask the site owner for its controlled classification record, including the work area, atmosphere, classification system, relevant gas or dust group, temperature constraints and local jurisdiction. Do not map a US Class/Division designation to an IEC zone by intuition or use a certification from one jurisdiction as automatic permission in another. The US OSHA hazardous-location rule, 29 CFR 1910.307, requires documented area classification and approval suited to the particular hazard; its wording and markings apply to its regulatory scope, not every country.
A quotation should identify where the operator will scan, carry and service the device. The scanner may be used inside a classified process area while charging takes place in a designated nonclassified room. That distinction does not itself authorize battery changes, docks or peripherals inside the hazardous area. Request the site’s procedures and the equipment instructions for each activity.
Match the approval to the exact configuration
Record the manufacturer’s legal product name and model suffix, hardware revision if relevant, approval or certificate number, issue and status, complete marking and installation instructions. Compare these with the site classification and the orderable bill of materials. IECEx explains that its online equipment certificate is the controlled source for a Certificate of Conformity; purchasers can look up the certificate and later issues. A catalog badge or a certificate belonging to a related model is not enough.
Check the exact battery, protective case, stylus, scanner attachment, communications accessory, dock and charging arrangement that the operator will actually use. Determine from the certificate schedule and manufacturer’s instructions which combinations and operations are covered. A component certificate alone is not an approval of an assembled handheld; the IECEx equipment-scheme overview distinguishes certified equipment from components that require additional assessment when incorporated into a system. Ask the issuing body or manufacturer about ambiguous variants instead of extending approval by analogy.
| Evidence | Decision it supports | What it cannot prove alone |
|---|---|---|
| Site classification record | Which approval and conditions are required at the work point | That a proposed handheld has that approval |
| Exact device marking and current certificate | Whether the listed device variant covers the specified classification | That every battery, cable or accessory is permitted |
| Certificate schedule and device instructions | Permitted configuration, conditions of use and servicing boundaries | That the business application works in the field |
| Controlled pilot and site sign-off | Whether the approved configuration performs the intended scan-and-record task | Approval of an unlisted substitute or later revision |
Use a hypothetical purchase gate
Editorial example only: a maintenance team proposes a handheld for asset-label checks in a plant area that its safety file classifies as hazardous. The supplier sends a photo of a rugged handheld and an IECEx certificate number, but the quote lists a different model suffix and an optional pistol grip. The team should not infer that the quoted combination is approved. It first checks the certificate’s equipment description and current issue, the device marking, the accessory list and any special conditions against the site’s documented classification. If the suffix or grip is absent or unclear, the safety owner seeks written clarification or a different certified configuration before any in-area pilot.
Once suitability is established, the team still has a separate workflow test: scan representative labels while wearing required protection, confirm the decoded value in the application, handle a failed scan without unsafe improvisation and reconcile the saved task. This confirms usability of the approved configuration, not the validity of the approval itself. A later battery or accessory substitution reopens the configuration check.
Specify a verifiable purchase and acceptance record
Put the classified location, required approval regime, precise device and accessory part numbers, certificate reference and issue, ambient conditions, charging/service restrictions and responsible site approver into the purchase specification. Require the delivered unit’s marking and documents to match the approved bill of materials. Keep business-app and barcode acceptance results separately. Do not rely on a generic “explosion-proof” marketing phrase, a high IP number or another model’s test report.
Use the handheld range only to identify potential configurations, then send the exact site requirement through Integration Support or Contact. No current AIDC GO product certificate has been supplied for this article; suitability for a hazardous area remains unconfirmed until model-specific documents and site review establish it.
