Standards for classifying hazardous areas

There are two main standards for the classification of hazardous areas:

• NFPA / NEC primarily classifies vapors or gasses as “Class I”; with dust, “Class II”; and with fibers, «Class III». Then, «Division 1» indicates that the explosive atmosphere is present or is likely to be present in normal operation, while «Division 2» considers that the explosive atmosphere is not present in normal operation, but may be present in abnormal operation of the process.
• IEC / ATEX classifies atmospheres by zones. “Zone 0” (gas) and “zone 20” (dust) are areas where explosive atmospheres are continuously present, for long periods or frequently. Meanwhile, in “zone 1” (gas) and “zone 21” (dust), the explosive atmosphere is likely to appear in normal operation. In «zone 2» (gas) and «zone 22» (dust), explosive atmospheres are not likely to occur in normal operation of the process and if they do occur it will be for a short time.

Fire safety in fueling operations and motor vehicle repair facilities is dependent on the key requirements of NFPA 30A.

• Flammable fuels for dispensing can present serious hazards. Reduce risk by complying with the 2018 edition of NFPA 30A, Code for Fuel Supply Facilities and Repair Stations, which introduces the latest regulations for fuel storage and pipelines, fueling systems, and retail operating procedures. of fuel, fuel dispensing for maritime use, and fuel dispensing for vehicle fleets. NFPA 30A also covers gaseous fuels for motor vehicles when supplied in the same facilities as liquid fuels.
• NFPA 30A is an essential resource for architects and engineers dealing with the design and construction of fueling facilities, AC and other professionals with supervisory / review authority, and for facility owners and operators.

General Features Explosion-proof components

Power Conditioners

• Provides excellent noise filtering and surge suppression to protect connected equipment from damage, degradation or misoperation. Is a perfect choice where dirty power, caused by impulses, swell, sags, brownouts and waveform distortion can lead to costly downtime because of damaged equipment.

Hardwired Surge Protection

• Surge Protection Device (SPD’s) is a hard wired SPD designed to be installed at the service entrance, branch panels or dedicated sensitive electronic loads. These surge protector feature all mode protection, LED and audible alarm status indication, sinewave tracking and Form C dry contacts.
• These surge protector meet UL 1449, 2nd Edition standards and provide AIC ratings for appropriate and safe distribution panel use. These Surge Protection Devices come in a compact design allowing the user to install the product as close as possible to the sensitive load.
