A low profile explosion proof by containment enclosure includes a base wall having first and second edge sections that are joined with third and fourth edge sections to define a substantially planar surface. First and second side walls extend from the first and second edge sections, and third and fourth side walls extending from the third and fourth edge sections and are joined with the first and second side walls. The base wall, first and second, and third and fourth side walls define an interior zone. A cover is coupled to the first and second, and third and fourth side walls to enclose the interior zone and provide containment to any flammable events. At least one of the first and second side walls, third and fourth side walls, base wall, and cover includes one or more unobstructed openings that provide fluid drainage while also providing containment to any flammable events.

1. A low profile explosion proof by containment enclosure comprising: a base wall having first and second opposing edge sections that are joined with third and fourth opposing edge sections to define a substantially planar surface;first and second opposing side walls extending from the first and sec
1. A low profile explosion proof by containment enclosure comprising: a base wall having first and second opposing edge sections that are joined with third and fourth opposing edge sections to define a substantially planar surface;first and second opposing side walls extending from the first and second opposing edge sections;third and fourth opposing side walls extending from the third and fourth opposing edge sections and being joined with the first and second opposing side walls, the base wall, first and second, and third and fourth opposing side walls defining an interior zone; anda cover coupled to the first and second, and third and fourth opposing side walls, the cover being spaced from the base wall so as to enclose the interior zone and provide containment to any internal flammable events;wherein at least one of the first and second opposing side walls, third and fourth opposing side walls, base wall, and cover includes one or more unobstructed openings that provide fluid drainage while also providing containment to any internal flammable events;wherein the aspect ratio of the openings is such that all flame is prevented from passing from a region inside of the enclosure to and region outside of the enclosure. 2. The low profile explosion proof by containment enclosure according to claim 1, further comprising a flange extending about the first and second, and third and fourth opposing side walls. 3. The low profile explosion proof by containment enclosure according to claim 2, wherein the flange has a thickness between about 0.667-inches (about 16.94-mm) and about 0.780-inches (about 19.81-mm). 4. The low profile explosion proof by containment enclosure according to claim 2, further comprising: a plurality of mechanical fasteners extending through the cover and into the flange. 5. The low profile explosion proof by containment enclosure according to claim 1, wherein the one or more unobstructed opening includes at least two unobstructed openings in each of the first and second opposing side walls. 6. The low profile explosion proof by containment enclosure according to claim 1, wherein the one or more unobstructed openings includes a diameter of between about 0.040-inches (about 1.02-mm) and about 0.096-inches (about 2.44-mm). 7. The low profile explosion proof by containment enclosure according to claim 6, wherein the one or more unobstructed openings includes a diameter of about 0.060-inches (about 1.52-mm). 8. The low profile explosion proof by containment enclosure according to claim 1, wherein the one or more unobstructed openings includes a length of between about 0.125-inches (about 3.18 mm) and about 1.0-inches (about 25.4-mm). 9. The low profile explosion proof by containment enclosure according to claim 8, wherein the one or more unobstructed openings includes a length of about 0.815-inches (about 20.7-mm). 10. The low profile explosion proof by containment enclosure according to claim 1, further comprising: a plurality of fastener receiver members extending substantially perpendicularly outward from the base member, each of the plurality of fastener receiver members including a central passage. 11. The low profile explosion proof by containment enclosure according to claim 10, further comprising: a plurality of fastener openings formed in the cover, each of the plurality of fastener openings being registered with a corresponding one of the plurality of fastener receiver members. 12. The low profile explosion proof by containment enclosure according to claim 11, wherein the central passage of each of the plurality of fastener receiver members includes a plurality of threads. 13. The low profile explosion proof by containment enclosure according to claim 12, further comprising: a plurality of mechanical fasteners extending through corresponding ones of the plurality of fastener openings and threadably engaging with the plurality of threads in each of the plurality of fastener receiver members. 14. A method of relieving pressure in a low profile explosion by containment enclosure having first and second, and third and fourth opposing side walls, the method including: allowing air to pass through at least two unobstructed openings formed in one or more of the first and second, and third and fourth opposing side walls, the openings having an aspect ratio and being disposed so as to prevent all flames that may exist in an interior portion of the low profile explosion proof by containment enclosure from passing to an exterior of the low profile explosion proof by containment enclosure. 15. The method of claim 14, further comprising: passing fluid through the at least two unobstructed openings from the interior portion of the low profile explosion proof by containment enclosure.
