Additionally, we are engaged in efforts designed to further mitigate wildfire risk on multiple levels by inspecting, repairing and hardening our electrical infrastructure, generating better and more location-specific information about high-threat weather conditions, proactively shutting off power in weather conditions known to pose a serious wildfire threat, and trimming excess vegetation that can damage power lines and create an ignition source. We are also actively working with state agencies and local communities to develop the shared solutions and coordinated management needed to most effectively address the growing wildfire threat in California."

Whatever the risk, good machine maintenance and hygiene is central to risk mitigation, because a foreign object lodged in front of the laser can be an ignition source. At the same time, users need to prevent ignition sources reaching areas of particulate build up--this can be as simple as the use of a spark trap, spark arrestor or inerting powders.

For a fire or explosion to occur, the refrigerant must be released from the refrigeration loop, accumulate to a concentration within the flammable range, and be ignited by a competent ignition source. The probability of all three events occurring depends upon (1) the type of equipment, (2) the operational state of the equipment, and (3) the location of the equipment.

The fear is that any ignition source could ignite fumes from the leak, which could in turn mix with petrol fumes.

The automaker is recalling the vehicles because they may leak petrol following a rear-impact crash and a rollover, which in the presence of an ignition source, increases the risk of fire.

Other research has shown a much stronger probability of fuel/lubricant droplets serving as the primary ignition source [6,11], and a great deal of recent work has focused on understanding the effects of fuel [12,13,14,15] and lubricant [16,17,18,19,20,21,22,23] properties, and the interaction of fuel sprays and lubricating oil in the top crevice region [6,24,25].
