LA's San Fernando and San Gabriel valleys regularly hit 110°F during summer heat events — and Cal/OSHA's Los Angeles district office is one of the most active in the state. HeatLog builds your daily heat illness compliance record automatically, every day a threshold is crossed, so you're never caught unprepared.
HeatLog monitors the weather at each Los Angeles job site, triggers the checklist when thresholds are crossed, and saves a timestamped record that stands up to a Cal/OSHA inspection.
Every morning at 6am, HeatLog checks the NOAA National Weather Service for each of your site addresses — whether it's in the Valley, South Bay, East LA, or anywhere in LA County.
Your supervisor gets an email alert with a one-click compliance checklist: shade, water, cool-down breaks, buddy system. Takes under 60 seconds to confirm.
The confirmed record is saved with a server timestamp that cannot be backdated. Download your full monthly audit log as a PDF and hand it to an inspector on the spot.
Los Angeles County has the most workers of any county in California. Its size means heat compliance touches industries that don't always think of themselves as high-heat environments — from Valley construction to Vernon food processing.
LA's perpetual construction market — residential infill, commercial, infrastructure — employs hundreds of thousands of outdoor workers. Valley job sites routinely reach the 95°F high-heat threshold by mid-morning in summer.
Landscape maintenance is one of the most heavily cited industries in Cal/OSHA heat enforcement statewide. LA's massive residential and commercial landscape industry makes this a significant compliance exposure.
Outdoor film, TV, and event production crews — grip, electric, stunts, extras — working on location in LA heat. If your crew is working outside when it's 80°F, §3395 applies.
The Vernon industrial district and greater LA food processing corridor includes bakeries, meat processing, and prepared food facilities where heat-generating equipment pushes indoor temps above the 82°F action level.
Warehouses in Commerce, Carson, and the South Bay that lack full climate control. On hot Valley days, uncooled warehouses frequently exceed the 82°F threshold that triggers §3396 documentation.
Street maintenance, utility installation, and public works crews across LA County. DWP, contractors, and municipal crews all fall under §3395 for any outdoor work during heat season.
Yes — and LA is one of the most active enforcement districts in the state. Cal/OSHA inspects after worker complaints, after reported heat illness incidents, and during unannounced sweeps focused on high-risk industries. With the largest workforce in California, LA employers are proportionally the highest target. Heat violation fines are assessed per worker per violation, which means a single inspection at a construction or landscaping site can result in six-figure penalties.
Yes, but the threshold determines when documentation kicks in. §3395 is triggered at 80°F for the action level and 95°F for high heat. Coastal areas may have fewer high-heat days, but a September heat event in Santa Monica or El Segundo can still push past 80°F — triggering the action level requirement. HeatLog only logs when a threshold is actually crossed, so coastal sites will simply have fewer records. The key is that when a threshold is crossed, you have documentation.
Inspectors want to see: daily temperature at each work location, documentation that water (1 qt/hr per worker) was available, confirmation that shade was accessible within 2 minutes of request, logged cool-down rest periods on high-heat days (95°F outdoor / 87°F indoor), and evidence the buddy system and emergency response plan were followed. HeatLog captures all of this in a single timestamped PDF you can hand over on the spot — with server-recorded timestamps that cannot be backdated.
