Zone 1 means the project site may produce combustible gas, vapor normally when the project operates, here are some recommended explosion proof lighting, control box and fittings for your options subject to EC60079-ATEX and IEC60079-IECEx standard.

What Is Zone 1?
Zone 1 Definition
In Simple Word

Zone 1 area means ignitable concentrations of hazards, flammable gases, vapors, or liquids, are likely to exist under normal operating conditions.

In Quantitative Measurement

Zone 1 hazardous area lighting means ignitable concentrations of hazards, flammable gases, vapors, or liquids, present from 10 hours to 1,000 hours every year.

Area Classification Zone 1
In Accordance with ATEX IEC60079
Where ignitable concentrations of flammable gases, vapors, or liquids:

Are likely to exist under normal operating conditions

May exist frequently because of repair, maintenance operations or leakage

FAQs about Zone 1
Q
What is a Zone 1 area? What is the meaning of Zone 1?
A
Zone 1 area is a location where an explosive atmosphere containing a mixture with air or flammable substances such as gas, vapor or liquid is likely to occur in normal operation or under presenting frequency from 10 hours to 1.000 hours every year. Zone 1 is the area of high risk for the presence of gas or vapor potentially explosive, All sources of ignition related to electrical, static, mechanical, heat are protected so that the equipment can operate safely within potentially flammable atmospheres.

Q
What is ATEX Zone 1 certification?
A
Within Europe, when any kinds of electrical equipment is intended for use in a potentially hazardous area, the equipment must be ATEX certified as per the EU directive 60079- 2014/34 standard. ATEX Zone 1 certification for electrical equipment is certified issued by ATEX authorized body to indicate the users that the electrical equipment comply with requirements of zone 1 in the EU directive 2014/34 standard and can be permitted to be used in Zone 1.

Q
What is the difference between Zone 1 and Zone 2?
A
Zone 1 contains a hazardous gas and air mixture under normal operating conditions. Zone 2 contains a hazardous gas and air mixture only under abnormal operating conditions, that is say hazardous gas exist for a long time for Zone 1, and short time for Zone 2. Among all zones, Zone 1 is already a serve environment with high risk, Zone 2 is a safer area with middle risk compared with Zone 1, thus a zone 1 electrical equipment can be also used in Zone 2 environment.

Q
What is Zone 1 in oil and gas?
A
Oil and gas industry inherently easily produce any flammable substance including flammable gas, vapor, mist considering the whole process from exploitation, transportation and refinery. Zone 1 in oil and gas means location where the mixture of oxygen and flammable substance mentioned above likely to occur in all kinds of plants related to crude oil, nature gas, LNG, LPG, explosion proof zone 1 electrical equipment should be installed to protect the safety.

Q
What is a Zone 0 location?
A
Zone 0 is an area in which an explosive atmosphere is present continuously for long periods of time normally more than 1,000 hours every year or will frequently occur. Zone 0 is the most risky area within all zones, in order to limit the heat and energy at utmost to avoid the ignition source, only some low current instrument, such as remote controller, display front panel, instrument board can be used with intrinsic safety Ex i explosion proof technology.
