Is an iPad intrinsically safe? Apple, Samsung and Microsoft tablets in hazardous areas

None of the standard tablets from Apple, Samsung, Microsoft, Lenovo or Google carries an Ex marking, so none of them is intrinsically safe or approved for Zone 1 or Zone 2 on its own. There are three ways to get a tablet into a classified area. The first is a certified case around a standard tablet. The second is a factory conversion, where a specialist rebuilds the tablet inside a certified housing. The third is a dedicated Ex tablet, designed for hazardous areas from the start. This guide goes brand by brand through what exists for each.

Why a standard tablet can’t go into a hazardous area

A tablet can ignite a gas or dust atmosphere in a few ways. The lithium-ion battery can fault and overheat, surfaces can get hot under load, and sparks can form at the charging port, contacts or buttons. None of this shows up in normal office use, which is why consumer tablets aren’t designed or tested for it.

Rugged ratings don’t change that. IP68 covers dust and water, and MIL-STD-810H covers drops, vibration and temperature. Neither assesses ignition risk. A tablet in a tough case is still an uncertified tablet, and in a classified area it can only be used under a work permit backed by gas testing.

Certified tablets manage ignition risk in one of two main ways. Intrinsically safe tablets limit the electrical and thermal energy inside the device so it stays below what could ignite the atmosphere. Explosion-proof (flameproof, Ex db) designs place the tablet inside an enclosure built to contain an internal ignition and stop flame reaching the surrounding atmosphere. Both can be certified for Zone 1. Zone 2 products also use other methods, such as increased safety (Ex ec) and restricted-breathing enclosures (Ex nR). Whichever method is used, the proof is the Ex marking on the label and the certificate number behind it.

Apple iPad

No iPad is certified on its own, but the iPad has the widest choice of certified cases and conversions of any tablet. That reflects how many field teams already use one. Current iPads bring strong cameras, LiDAR on the Pro models, a large catalog of industrial apps, long software support and a device most people already know how to use, so it’s natural for operators to want the same tablet inside the zone.

iPad options for Zone 1

For Zone 1, the iPad sits inside a flameproof (Ex db) enclosure. These products are explosion-proof, and they’re certified for the same zones as intrinsically safe tablets.

The Xshielder iPad Pro 11-inch is the only Zone 1 option in our data for a full-size iPad. It’s a flameproof cover for a standard iPad Pro 11-inch (M5), rated Ex db IIC T6 Gb for gas and Ex tb IIIC T80 °C Db for dust under ATEX, which covers every gas group, the strictest temperature class and conductive dust. Xshielder confirms that the rear camera with 4K ProRes video, LiDAR, the front camera with Face ID, stylus input, USB-C charging and data, and audio all work through the cover. The limits are worth planning around. The certificate is ATEX only, with no IECEx or North American listing yet, the ambient rating tops out at +45 °C, it weighs 1,350 g with the iPad, and its IP65 rating is pending testing.

Every other Zone 1 iPad option is built around the iPad mini. The Atexxo Zone 1 iPad mini 7 is a factory conversion certified under ATEX and IECEx, with a CSA listing for North America, at IIC T4 and 990 g. Its dust group is IIIA, which covers combustible flyings only, and Touch ID is removed. The Xciel XCZ1 iPad mini 7 and The Joy Factory aXtion Extreme iPad mini are flameproof cases with IECEx certificates. Their ATEX markings come from a distributor and a datasheet, and the ATEX certificates aren’t published, so we treat those markings as unconfirmed. Xciel lists gas group IIB, which doesn’t cover hydrogen or acetylene.

iPad options for Zone 2

Zone 2 has more choice. Atexxo converts several iPads for Zone 2/22, including the iPad Pro 11-inch, the iPad (A16) and the iPad mini 7, and Xciel sells its XCRiPad cases, which the customer fits. Both makers state their markings without publishing the certificate or declaration of conformity, so we haven’t been able to check them. The Armadex Ex UniCase takes a different route. It’s a universal restricted-breathing (Ex nR) case for 10- to 11-inch tablets with published ATEX and IECEx certificates for Zone 2/22, and it takes a standard iPad (A16), iPad Air or iPad Pro from Armadex’s supported list. Armadex lists it for pre-order and also says it ships from stock, so check lead times.

Our best iPads for hazardous areas page ranks these options, and Xshielder’s guide to intrinsically safe tablets and iPads covers rolling an iPad out in Zone 1, from app setup to training.

Samsung Galaxy Tab

Samsung builds the Galaxy Tab Active5 and Active5 Pro for field work, but we found no hazardous-area certification for either from Samsung. As with the iPad, certification comes from a specialist.

Atexxo converts the Galaxy Tab Active5 for Zone 1. The Atexxo Zone 1 Galaxy Tab Active5 is a flameproof (Ex db) conversion rated IIC T6 with dust group IIIC, under published ATEX and IECEx certificates, and it weighs 940 g. It’s charged, and its SIM changed, in a safe area only, and our data doesn’t confirm that the Active Key or the S Pen work through the housing. For Zone 2, Atexxo also converts the Galaxy Tab Active5 Pro, Tab A9, Tab S9 FE and Tab S10 FE, again with markings we haven’t been able to check. The Armadex Ex UniCase lists the Galaxy Tab S11, Tab S10 FE and Tab A11+ for Zone 2/22.

Teams that want Samsung’s software without a conversion can look at dedicated Ex tablets instead. The ecom Tab-Ex 05 DZ1 runs Samsung’s One UI with Knox and is certified for Zone 1/21 at IIC T6, with a North American Class I Division 1 listing.

Microsoft Surface and Windows tablets

No Surface is certified on its own, and we found no Surface option for Zone 1. For Zone 2/22, the Armadex Ex UniCase lists the Surface Go 4 for Business. The Joy Factory sells an aXtion Extreme MP case for the Surface Pro 10 that it lists for Class I and II, Division 2, in North America, with the tablet and case certified together as one unit. It also says its aXtion Extreme cases for Surface comply with ATEX Zone 2, but we found no published ATEX certificate for them.

Teams that need Windows in Zone 1 usually choose a dedicated tablet. The Eaton MTL GECMA IS Tablet PC is intrinsically safe (Ex ia) and runs Windows 11 IoT Enterprise on an Intel Atom processor, so x86 desktop software runs natively. The i.safe MOBILE IS945.1 runs Windows 11 IoT Enterprise on an Arm processor, where x86 applications run through emulation. Our best Windows tablets for hazardous areas page compares them with the Zone 2 options from Getac, Durabook, Winmate and BARTEC.

Lenovo, Google and other tablets

We found no certified case, conversion or Ex version for Lenovo’s tablets or the Google Pixel Tablet when we checked in October 2026. Universal cases such as the Armadex Ex UniCase only cover the tablets on their maker’s supported list, so a tablet of the right size isn’t automatically covered. If a supplier says otherwise, ask for the Ex marking and certificate that names your exact tablet model.

Case, conversion or dedicated tablet: how to choose

The three routes suit different fleets. The table sums up the main differences, and the specifics vary by product.

For most iPad fleets, a certified case for a current model keeps current hardware in the zone. The camera, LiDAR and apps are the same as on the iPads used outside it, and the tablet is managed the same way. A conversion suits teams that want the smallest Zone 1 iPad and can accept a fixed unit. A dedicated tablet suits sites that need a wide temperature range, Windows desktop software or charging inside the zone, which in our data only some i.safe MOBILE tablets allow.

What to check before you buy

Start with the zone and the atmosphere. A tablet carried into Zone 1 needs a Zone 1 rating (equipment protection level Gb or Ga), and the gas group and temperature class on the marking have to cover the substances on your site. IIC covers every gas group, and T6 is the strictest temperature class. Dust areas need the right dust group too, and IIIC is the only one that covers conductive dust.

Then check the paperwork. A published ATEX or IECEx certificate number lets you confirm the marking for yourself, and the IECEx online database makes IECEx certificates easy to look up. Several Zone 2 tablet products don’t publish theirs, so ask for the certificate before you order. Check the certified ambient range against your hottest site, and the conditions of use, which say where the tablet may be charged and opened.

Last, check what still works once the tablet is enclosed. Cameras, Face ID or Touch ID, stylus input, buttons and charging all depend on the housing, and the makers’ answers differ. Our tablet pages list what works through each case and conversion, as far as each maker states it.
