San Bernardino County stretches from the valley floor to the High Desert, and summer highs regularly top 105°F across its warehouse corridors and construction sites. Whether your crews are staging freight in Fontana or framing homes in Rialto, HeatLog builds your daily heat illness compliance record automatically. When Cal/OSHA calls, your documentation is ready.
HeatLog monitors the weather at each San Bernardino County 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 San Bernardino County addresses — from the valley floor to Victorville and Barstow.
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.
San Bernardino County is home to one of the largest warehouse and distribution footprints in the country along the I-10/I-15 corridor, plus a steady construction pipeline and a growing manufacturing base. Most county employers are covered by at least one of California's two heat regulations.
Fontana, Rialto, and San Bernardino host some of the largest fulfillment and cross-dock facilities in the state. Action level: 82°F — routinely reached in uncooled buildings during summer.
Residential and commercial development across the county keeps framing, roofing, grading, and infrastructure crews outdoors all summer. High-heat threshold: 95°F.
Metal fabrication, plastics, and assembly operations across the county's industrial parks. Heat-generating equipment raises indoor temps well above ambient.
Drivers and yard crews staging, loading, and inspecting trailers outdoors at the county's distribution hubs fall under the outdoor heat rule for the time spent outside the cab.
Crews servicing the county's residential and commercial developments — one of the industries with the highest Cal/OSHA citation rates for heat illness violations statewide.
Utility, telecom, and agricultural crews working the Victorville/Barstow corridor face some of the county's most extreme daytime highs.
Yes. Title 8 §3396 (effective July 23, 2024) covers any indoor workplace where workers are exposed to heat illness risk, and the county's distribution warehouses are a primary enforcement target. The action level is 82°F, which uncooled or partially cooled buildings in Fontana, Rialto, and San Bernardino routinely reach on summer days above 100°F outside. Once 82°F is hit, documentation of water access, rest opportunities, and worker monitoring is required. At 87°F, mandatory cool-down periods apply. HeatLog triggers automatically and captures everything in one place.
Yes. HeatLog supports unlimited job sites under one subscription. Each site gets its own weather monitoring using its specific address — so a warehouse in Fontana and a crew in Victorville each get the correct local temperature check. Add a site, enter the address, set the contact email, and HeatLog handles the rest. When an inspector shows up at any site, you pull up that site's PDF log and hand it over.
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.
