By opting for the Smart-Ex® 02 or the Ex-Handy 10 you are not only acquiring a smartphone that is rugged, reliable and intrinsically safe, but one that also caters for the safety of your employees around the world.
Ecom’s intrinsically safe smartphones with lone worker protection (LWP) functionality have been specifically designed for the safety of people working alone. The requirements of the users vary as they are from various industrial sectors requiring modern communication technology with personal emergency response devices.
This was the drive for Ecom to provide safe working in high-risk and isolated areas. These phones are able to help locate anyone who has suffered an accident and immediately initiate the necessary measures.
Employees are exposed to higher risks and rely on fast assistance in case of emergency. With increased risk, the use of a personal emergency response system is recommended or even mandatory in case of critical hazard. In the case of deficiencies relating to workplace safety, injuries, accidents and subsequent damage to people or plants may occur.
Ecom Smart-Ex 02 & Ex-Handy 10
For people working in hazardous areas or extensive terrains, companies must ensure that the rescue chain is always guaranteed. The mobile communication device must also be triggered if the injured person is incapacitated without anyone noticing the accident. Ecom smartphones and featurephones are components of a tested and according to BGR-139 certified Lone-Worker-Protection-Solution or person-emergency-response system from Swissphone.
They are equipped with dedicated side buttons for one-touch access to PTT services such as the yellow PTT button and the red emergency button. Together with fully developed Lone-Worker-Protection-Applications from well-known vendors on the market, these mobile solutions reliably protect the user and document the process.
Smartphone or tablet send an emergency signal to the control center in case of emergency by pushing the button (will-dependent emergency call) as well as by triggering the position or impact sensor (automatic emergency call). In case of a triggered alarm, an automatic call setup is the standard procedures for checking the constitution of the employee.

Ex d Flameproof
Thanks to HazardEx for allowing T&D to publish the following article
This article by Jacob Thumberger, Business Assurance Product Certification Specialist at DNV GL – Business Assurance, looks in detail at the general requirements for obtaining Ex d certification for hazardous area location equipment such as enclosures.
Whereas other protection types aim to prevent an explosion by removing one of the legs of the fire triangle, the intent of the Ex d type of protection is to contain/quench an explosion by use of a suitably designed enclosure where all of the paths from the inside of the enclosure to the outside atmosphere, called flamepaths, are tightly controlled.
In order to contain an explosion, the enclosure walls must be suitably thick. The exact thickness needed will depend on the enclosure volume, the internal configuration, and the specific explosive gases that the enclosure is intended to be used with.
In order to quench an explosion, all flameproof joints must adhere to strict requirements. The exact requirements depend on what kind of joints are utilized (flanged, cylindrical, spigot, threaded, etc.), and the flammable gases that will be present. In all cases, the intent is the same: prevent an internal ignition from being transmitted outside the enclosure.
For threaded joints, this is accomplished by ensuring a minimum number of engaged threads, in addition to minimum thread length and tolerance requirements. For non-threaded joints, this is accomplished by maintaining minimum width and maximum gap values for the flameproof joint, in addition to testing for non-transmission of an internal ignition. Specific details on these requirements can be found in Clause 5 of EN/IEC 60079-1.
As with any hazardous area certification, all Ex d designs must be assessed and tested against the applicable requirements of EN/IEC 60079-0 (General Requirements) and also against the requirements of EN/IEC 60079-1 (Flameproof Enclosures).
For AEx certification, the design is evaluated against the U.S. versions of the 60079-0 and 60079-1 standards that contain national deviations that make them compatible with Article 505 of the National Electrical Code (NFPA 70).
The requirements for flameproof enclosures to be used under the Class/Division system in the National Electrical Code have different construction and test requirements. As a minimum, this includes:
– Determination of maximum temperature rise (either via assessment or testing) and assignment of temperature classification (i.e. T4 or T135°C). These requirements are defined in Clause 5.
– Assessment of enclosure materials, both metallic (Clause 8) and non-metallic (Clause 7).
– Assessment of any safety critical fasteners (Clause 9).
o Note: These requirements are supplemented by Clause 11 of EN/IEC 60079-1.
– Verification of earthing provisions (Clause 15).
– Assessment of enclosure entries (Clause 16).
o Note: These requirements are supplemented by Clause 13 of EN/IEC 60079-1.
– Enclosure testing, including resistance to impact, drop test (portable equipment), and ingress protection testing (where IP rating is safety critical). These requirements are detailed in Clause 26.4.
o Note: Where critical enclosures are constructed of non-metallic materials, thermal endurance to heat/cold is also applicable, and is conducted prior to all other enclosure tests (Clause 26.4.1.2).
– Verification of product marking details, including any applicable warnings (Clause 29).
– Verification that product instructions contain all applicable details, including a recapitulation of all certification marking details, warning markings, and special conditions (X) from the certificate (Clause 30).
Note: While the above list details the minimum requirements to be considered for all Ex d designs, it is by no means all-inclusive. Depending on the specific design and construction of the Ex d equipment under consideration, other requirements may be applicable. Reference EN/IEC 60079-0 for a full listing of all applicable general requirements.
The following assessment and testing is applicable for nearly all Ex d certifications:
– Identification and verification of all flameproof joints (Clause 5). This may include, but is not limited to, threaded covers, flanged covers, and threaded joints. Non-threaded flameproof joints shall be in accordance with Tables 2 and 3. Threaded flameproof joints shall be in accordance with Tables 4 and 5.
– Assessment of fasteners and openings (Clause 11).
– Assessment of enclosure entries (Clause 13).
o Note: These requirements are supplement the entry requirements of Clause 16 of EN/IEC 60079-0.
– Performance of Ex d type testing, including:
o Determination of explosion pressure – Reference pressure (Clause 15.2.2).
Note: For ambients below -20°C, additional consideration is necessary.
o Overpressure test (Clause 15.2.3).
o Test for non-transmission of an internal ignition (Clause 15.3).
Note: For ambients above +60°C, additional consideration is necessary.
– Assignment of routine testing, if any (Clause 16).
– Verification of product marking details, including any applicable warnings (Clause 20).
o Note: See also the marking requirements of EN/IEC 60079-0 Clause 29.
– Verification that product instructions contain all applicable details.
o Note: See also the instruction requirements of EN/IEC 60079-0 Clause 30.
Depending on the specific design and construction of the equipment under consideration, the following additional requirements may apply:
– Where cemented joints or fused glass joints are utilized, the requirements of Clause 6 apply.
– Where operating rods or shafts/bearings are utilized, the requirements of Clauses 7 or 8 apply, respectively.
– Where breathing or draining devices are utilized, the requirements of Clauses 10 and 15.4 apply. In addition, the requirements of Annexes A and B may also apply.
– Where switchgear for Group I is being evaluated, the requirements of Clause 17 apply.
– Where lamps holders or lamp caps are being evaluated, the requirements of Clause 18 apply.
– Where safety depends on one or more non-metallic materials, the requirements of Clause 19 apply.
o Note: These requirements do not apply to sealing rings of cables glands (see Clause C.3 instead), cemented joints (see Clause 6 instead), glass (see Clause 9 instead) or non-metallic parts on which the type of protection does not depend.
– Where the equipment under consideration is a cable gland, thread adapter, or bushing, the requirements of Annex C apply.
– Where the equipment under consideration is an empty flameproof enclosure, or where an already certified empty flameproof enclosure is being utilized, the requirements of Annex D apply.
– Where the equipment under consideration incorporates one or more cells or batteries, the requirements of Annex E apply.
Note: The following documentation requirements are taken from IECEx OD 017, Clause 4.1 (general requirements):
– All drawings shall be identified by: Drawing Number; Revision Number; Date of Revision; Title; Name of the Design Authority in whose Drawing Record System the drawing is recorded (with relationship to the manufacturer if different).

Note: The following documentation requirements are taken from IECEx OD 017, Clause 4.2 (flameproof enclosure d)
It is a good idea to create a certification drawing or drawings that contains all of the necessary information critical to Ex d certification rather than using production drawings. When a product is certified, the drawings used for the certification become “schedule drawings”, which means they will be listed in the certificate and any changes to those drawings have to be approved by the certification agencies before they can be applied.
The production drawings then become “related drawings”, which of course need to be linked to and match the requirements on the certification drawings, but changes to these drawings that do not affect the Ex d requirements can be made without having to have them pre-approved by the certification agency.
– Length of flamepath and maximum flamepath gap for each constructional gap/joint with maximum constructional tolerance.
– Length, size and minimum yield strength or grade of fasteners. Fastener data and characteristics may be included in a table cross referenced to the applicable drawing(s)
– Spacing of bolt holes in covers.
– Size and tolerance of clearance holes for fasteners. This may be included in a table cross referenced to the applicable drawing(s)
– Depth of drilling and tapping. This may be included in a table cross referenced to the applicable drawing(s)
– Minimum thickness of metal around holes. This may be included in a table cross referenced to the applicable drawing(s)
– Maximum and minimum diameter of shafts and bores together with maximum “m” and minimum “k” radial clearances of rotating parts.
– Location and details of threaded entries, including range of sizes and maximum number, pitch, class of fit, length of thread provided in enclosure (chamfers and undercuts taken into account)
– Area in which cable entries, switch operators, windows, receptacles etc may be fitted to be shown.
– Method of retaining a non-threaded fitting e.g. a fitting having a spigot joint.
– Hole spacing on face of enclosure where a certified component is to be fitted.
– Overall dimensions of the enclosure including minimum wall thickness
– Weld type and size.
– Minimum thickness of window, material and method of mounting.
– Surface roughness of flamepaths.
– Cemented joints require cement to be specified and manufacturers data sheet submitted and the shortest distance through the cemented joint is to be specified.

o Location of sources of heat, for temperature classification purposes, for temperature withstand of plastic parts, window cement, other potting materials, cable entries, etc., and for confirming the local ambient for items such as IS safety barriers
o Dimensions relevant to pressure piling effects
o Where the certificate is to cover variations in content, sufficient detail of the range must be given so that the design limits for each variant are absolutely clear. The certification agency can then select the worst-case arrangement(s) for test purposes.
1) Once a design is ready for certification, the first step in obtaining certification is to prepare the certification drawings. These drawings will detail all certification critical aspects of the design.
a. Note: Reference the previous two sections for key features to be included on these drawings.
2) After preliminary certification drawings are available, a request for quote (RFQ) and be made. In the RFQ, you will answer various questions which will help us determine exactly what certification(s) you require.
3) In nearly all cases, testing will be required for Ex d certification. During the RFQ phase we will help you determine the quantity of samples required for testing, and what configurations are necessary.
a. Note: As a minimum, two (2) samples are necessary. Where safety depends on non-metallic materials, up to four (4) samples may be necessary.
b. Note: Testing is normally conducted at our certification lab in Høvik, Norway. However, if you have the ability to conduct the necessary testing at your facility, we are able to witness testing on-site.
4) After testing is completed, all necessary certification reports will be completed. Minor drawing changes may be necessary during this time.
5) Draft certificates are generated and provided for customer review.
6) When all above steps are completed, the project is submitted for technical review and certificate issuance.
