Evaluate & Upgrade lighting to low
temperature & enclosed devices
FUEL FIRED EQUIPMENT - Are they designed, installed, & maintained so they aren't an ignition hazard? (See NFPA 31-Oil Burning, NFPA 54-Fuel Gas, NFPA 85-Boilers Combustion)?
CHECK fuel fired equipment against NFPA
31 requirements
STATIC ELECTRICITY - Does equipment contain design features that include - Conductivity, bonding & grounding, grounded metal combs, other effective means approved by the AHJ?
Consult electrician for Static Electricity minimizations
MACHINES & PROCESSING EQUIPMENT - Are they operated per manufacturer's specifications, at a condition of sharpness to minimize heat, and abrasives used within design life?
Look for equipment generation of sparks and
ignition
