Top Recommendations for i.safe MOBILE Explosion-Proof Smartphones & Tablets | PT Panca Makmur Baru

i.safe MOBILE explosion-proof smartphones offer a professional communication solution for companies requiring mobile devices to operate in environments with potentially explosive atmospheres. Unlike standard smartphones, devices intended for hazardous areas require more than just a rugged or water resistant body; they must possess protection and certifications that align with specific workplace area classifications.

For sectors such as oil & gas, petrochemicals, chemicals, pharmaceuticals, mining, manufacturing, utilities, and general industrial processing, the selection of communication devices must account for risks associated with flammable gases, vapors, mists, or dust.

One brand specifically dedicated to developing communication devices for these needs is i.safe MOBILE. This German manufacturer offers a range of smartphones, tablets, mobile phones, wearables, and accessories designed for industrial and hazardous area applications.

In this article, we will discuss:

• What are explosion-proof smartphones and tablets?
• What is the difference between Zone 1/21 and Zone 2/22?
• What do ATEX and IECEx certifications signify?
• Which i.safe MOBILE smartphones are suitable for industrial needs?
• Which explosion-proof tablets are the best fit?
• When should you choose Android versus Windows?
• What distinguishes Zone 1 devices from Zone 2 devices?
• Which features are truly essential for field workers?
• How do you select a device based on the specific job?
• Why is it important to purchase industrial devices through authorized distributors?

So, if you are looking for an explosion-proof smartphone, an ATEX tablet, an IECEx smartphone, a rugged smartphone for the oil & gas industry, or an intrinsically safe communication device, this guide serves as an excellent starting point before making your product selection.

Smartphone Explosion-Proof

The term “explosion-proof smartphone” is often used to refer to smartphones designed for use in areas with potentially explosive atmospheres.

However, technically speaking, not all rugged devices are automatically safe for use in hazardous areas.

A standard rugged smartphone might feature:

• IP68 rating
• Impact resistance
• Dust resistance
• Water resistance
• MIL-STD-810H compliance

Yet, these features do not automatically make the smartphone safe for use in areas requiring “Ex” (explosion protection) standards.

For hazardous areas, a device must feature a design that protects against ignition sources and possess certifications corresponding to the specific area classification.

i.safe MOBILE develops communication devices specifically intended for such environments; these devices hold various certifications such as ATEX and IECEx along with other regional approvals for specific models.

Therefore, when looking for an explosion-proof smartphone, do not simply ask:

“Is this phone rugged/shock resistant?”

The more important questions are:

“What certifications does this device have, and for which Zone is it rated?”

Understanding Zone 1/21 vs Zone 2/22 Before Buying

This is an aspect often overlooked when companies select industrial smartphones.

i.safe MOBILE categorizes devices for hazardous areas based on the classification of the usage environment, including Zone 1/21 and Zone 2/22.

Zone 1 and Zone 21

These areas carry a higher level of risk.

Zone 1 refers to areas where an explosive atmosphere consisting of flammable gases, vapors, or mists is likely to occur during normal operations.

Zone 21 refers to areas where an explosive atmosphere involving combustible dust is present.

Due to the higher risk level, devices intended for these areas require an appropriate level of protection.

i.safe MOBILE offers a range of ATEX and IECEx certified devices for Zone 1/21, including smartphones and tablets.

Zone 2 and Zone 22

Zone 2/22 involves different conditions.

Explosive atmospheres are not expected to occur under normal operating conditions but may arise for short periods during abnormal situations.

i.safe MOBILE also provides ATEX and IECEx devices specifically designed for Zone 2/22.

Therefore, Zone 1 and Zone 2 should not be treated as the same.

Mistakenly selecting a device simply because it is “explosion-proof” can result in equipment that is unsuitable for the specific requirements of the work environment.

Before purchasing, ensure you verify your company’s area classification.

ATEX vs. IECEx: What’s the Difference?

Two terms that almost always appear when looking for explosion-proof devices are ATEX and IECEx.

• ATEX
  ATEX is the European regulatory framework for equipment and protective systems used in potentially explosive atmospheres.

• IECEx
  IECEx is an international certification system that utilizes IEC standards for equipment used in explosive atmospheres.

In practice, it is not enough for a company to simply look for the “ATEX” or “IECEx” label.

It is more important to examine the specific markings and approvals, and then match them against the company’s hazardous area classification.

For instance, certain i.safe MOBILE devices feature markings for gas and dust, as well as specific temperature classifications. These details vary from one model to another.

The takeaway: do not select a device based solely on the brand name. Choose based on the correct model certification.

Company software requires Windows.

Recommendation: IS945.1 for Zone 1/21 requirements.

Choose a Tablet if:

• Reading technical documents frequently
• Using digital checklists
• A larger screen is required
• Performing maintenance/inspections
• Extensive data input is required
• Using industrial software
• Data visualization or technical drawings are needed

Recommendation: IS930.1/IS930.2 or IS940.1/IS940.2.

Choose a Windows Tablet if:
Company software requires Windows.

Recommendation: IS945.1 for Zone 1/21 requirements.

Don’t Just Look at the IP68 Rating

This is one of the most common mistakes made when purchasing industrial smartphones.

IP68 ≠ Explosion Protection.

IP68 relates to a device’s level of protection against the ingress of dust and water.

In contrast, Ex protection concerns how a device is designed to prevent it from becoming an ignition source within environmental conditions covered by its certification.

The same applies to MIL-STD-810H.

MIL-STD-810H indicates resistance to specific environmental conditions, but it is not a substitute for ATEX or IECEx certification.

Consequently, a smartphone might be:

Rugged + IP68 + MIL-STD-810H

but not necessarily:

ATEX/IECEx certified for your hazardous area.

This is why industrial companies must exercise greater care when selecting mobile devices.

A feature that is often underestimated, even though it is important for field workers

Industrial smartphones are about more than just being “rugged phones.” They offer a range of features that are highly practical for daily operations.

• Glove Friendly Screens
  Field technicians cannot always remove their safety gloves just to operate a smartphone. Certain i.safe MOBILE devices feature screens designed to remain responsive while wearing gloves.

• Amplified Loudspeaker
  Factory floors, compressor areas, workshops, and industrial plants are often extremely noisy environments. An amplified loudspeaker ensures that communications remain audible. The IS540.1, for instance, features an amplified loudspeaker specifically engineered for noisy work environments.

• Programmable Buttons
  Instead of navigating through multiple steps to launch an app, physical buttons can be programmed for specific functions, such as:
  • Push to Talk (PTT)
  • SOS
  • Lone Worker
  • Specific applications
  • Communication functions

• Replaceable Battery
  For long shifts or continuous operations, a replaceable battery offers a significant advantage. Users do not need to halt their work simply because the battery has run out. The IS540.1, IS541.1, and several i.safe MOBILE tablets feature replaceable batteries.

• ISM Interface
  This is a key feature distinguishing industrial devices from consumer smartphones. The ISM interface allows the device to connect to compatible industrial accessories, such as PTT devices or remote speaker microphones. The IS540.1, for example, is equipped with a 16-pin ISM interface for approved accessories.
