Burning pallets of hand sanitizer created challenges for Los Angeles firefighters.
"Water cannot be used safely in these conditions, as alcohol can float on water and spread flames. Crews are instead focused on protecting nearby structures and limiting environmental impact from runoff," an LAFD spokesperson told KCAL.
Sand dams were built to protect storm drains and firefighters considered using dirt to suffocate the flames.
Crews were expected to monitor the flames in the storage lot throughout the night.
