Narrative
Describe in detail what happened including the concern or potential issue, the environment (weather, terrain, fire behavior, etc), and the resulting health issue.
On May 30, 2017 we were putting in saw line on the Divide Creek Fire. We were using STIHL 461 saw's. Around 1100 the saw began to sputter and quit. The crew member took the saw out of the black away from the fire. He opened the saw with the fuel tank pointing away from himself. Opened the gas cap and the saw vented a little but did not spew out. As soon as the cap was fully removed the fuel boiled out of the tank very rapidly. This happened to another STIHL 461 on the same fire around the same time.
On May 31, 2017 we were putting in saw line on the Divide Creek Fire. Again we were using a STIHL 461. We were mopping up and cutting hot Juniper trees. The saw began to sputter and quit. The crew member took the saw out of the black and away from the fire. He opened the cap pointing away from himself. The saw vented from the cap but did not spew out. After the cap was fully removed it boiled out of the tank very rapidly. This happened twice with the same saw. Once at 1000 and then again at 1300.
Immediate Action Taken
Reporting Individual : please describe actions you took to correct or mitigate the unsafe/unhealthful event.
When the saw began to sputter and stop. We removed the saw from the black away from the fire line. We assumed it was vapor locking, and took the necessary precautions to avoid spilling the fuel on ourselves. When we opened the cap it was pointed away from ourselves.
