The most common fire standard for equipment fire protection in the oil, gas and petrochemical industry is UL 1709. This Underwriter’s Laboratories® standard applies to the “Rapid Rise Fire Tests of Protection Materials for Structural Steel.” In layman’s terms, UL 1709 is a high temperature fire test to prove that fire protection materials can withstand exposure to high rise temperature fires.
A UL1709 test evaluates the performance of protective material through a test in a furnace capable of reaching 2,000°F (1103°C) within 5 minutes of operation. The materials must provide sufficient fire protection so that equipment maintains structural integrity for 30 minutes in a 2,000°F fire.
Three main types of passive fire protection systems that can be used to fireproof equipment in accordance with UL1709 standards:
