INTRODUCTION
Spark Elimination
The workspace location must be configured and properly equipped to eliminate the potential for
mechanical or electrical sparking in compliance with your fire or other safety jurisdiction standards.
Power outlets for the oven and its vacuum pump to plug into must be located outside of the
workspace hazardous (classified) location to preclude the potential for sparking in the presence of
any explosive concentrations of gases or vapors. Ovens and pumps with hardwire power feeds may
be wired to the power source within the hazardous location or area, but the connection must meet
all safety compliance requirements for the location, division, or zone.
Additional Workspace Requirements
You must also satisfy all laws, ordinances, standards bodies, or regulations required by the safety
authority having jurisdiction for your location. This includes following relevant national and regional
laws as well as local ordinances dealing with potentially explosive vapors and gases.
Fire safety and other safety authorities having jurisdictions may have differing interpretations of
national directives or codes for hazardous location equipment. The oven manufacturer strongly
recommends consulting with these authorities to determine their compliance requirements when
purchasing a flammable solvents oven. These ovens are engineered to meet IECEx 60079-1 and
60079-2 with UL, CSA, and ATEX national and group differences for equipment safety requirements
for explosive atmospheres in their specified Zone or Division types.
Maximum Hazard Frequency Reminder (Zone 2, Class 1 Zone 2, and Class 1 Division 2)
The workspace location around the oven must conform to the requirements previously discussed in
this chapter and stated in the Safety Certs and Statements Chapter: Specifically, the maximum
hazard frequency allowed by the zone or division type.
