Intrinsically safe devices ensure that the available electric energy in the device to maintain low and will not ignite within any hazardous atmosphere. This is achieved by only supplying the device with low voltages and currents which still operate the device but ensure that no significant energy stored.
A recent study by Forrester has found that 12% of workers already use a tablet at work, so why not go mobile in dangerous environments? By adding intrinsically safe devices to your mobile technology, this will allow you to reap technological benefits currently available for phones and tablets in hazardous areas.
1) Preferred Method – Customer performs the installation by themselves and carry the workmanship liability. Direct ship to customer / end user accepts the below disclaimer:
You, the customer, acknowledge that you have no certification to install iPads into the XCiPad enclosure and that Xciel or SEE Forge has no responsibility for any installation not performed by Xciel or Xciel-approved installers. If the workmanship of such an installation is not properly performed, the customer bears all liability for any damages that may result from such workmanship. If the customer replaces the iPad in the XCiPad enclosure, or otherwise repairs the XCiPad enclosure, the same above-described disclaimers apply wherein Xciel and SEE Forge is not responsible.
2) Customer sends their mobile devices (iPhone/iPad) to the sell (Xciel or partners) to be installed and returned to the customer. Xciel to perform the installation and cary the workmanship liability. This must be agreed to in writing by SEE Forge or Xciel prior to shipping devices.
Classes and Divisions (cases)
Explanation of Intrinsically Safe Classes and Divisions.
The hazardous location ratings are divided into Class, Division, and Group to indicate the existence of flammable gases or vapors, ignitable dust, fibers, or filings under normal or unlikely conditions of operation.
Class l - Areas in which flammable gases or vapors may be present in sufficient quantities to be explosive or ignitable.
Class ll - Areas made hazardous by the presence of combustible dust.
Class lll - Areas in which there are easily ignitable fibers or flyings present, due to the type of material being handled, stored or processed-but in which such fibers or flyings are not likely to be in suspension in the air in quantities sufficient to produce ignitable mixtures.
Division 1 – Normal Situation: A hazard is present in the everyday normal production operation or during frequent repair and/or maintenance activity.
Division 2 – Abnormal Situation: Potentially hazardous material is expected to be safely confined within closed containers or closed systems, and will be present in the atmosphere only through accidental rupture, breakage, or abnormal operation.
Group A, B, C & D Gases and vapors in Class l locations are classified into four groups, by the code A, B, C, and D. These materials are grouped according to the ignition temperature of the substance, its explosion pressure and other flammability characteristics.
Groups E, F & G Combustible dust in Class ll locations are classified according to ignition temperature and the conductivity of the hazardous substance.
Flammable Gas, Flammable Liquid Vapor or Combustible Liquid Vapor, such as Hydrogen
Flammable Gas, FlammableLiquid Vapor or Combustible Liquid Vapor, such as Ethylene
Flammable Gas, Flammable Liquid Vapor or Combustible Liquid Vapor, such as Propane
Atmosphere contains combustible metal dust, including Aluminum, Magnesium and other commercial alloys
Atmosphere contains combustible carbonaceous dust, including Coal, Carbone black, Charcoal, and Coke
Atmosphere contains combustible dust, including Flour, Grain, Wood, Plastic, and Chemical
Always check what your company policy is for Classes, Divisions and Groups.
