Fresno averages over 100°F more than 20 days each summer — and Cal/OSHA doesn't send advance notice before inspections. HeatLog builds your daily heat illness compliance record automatically, every day a threshold is crossed. When an inspector shows up, you have timestamped documentation ready.
HeatLog monitors the weather at each Fresno job site, triggers the checklist when thresholds are crossed, and saves a timestamped record that stands up to an inspection.
Every morning at 6am, HeatLog checks the NOAA National Weather Service for each of your Fresno site addresses — the same government source a Cal/OSHA inspector can independently verify.
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.
Two California laws are currently enforced. Fresno's mix of outdoor agriculture and construction (§3395) plus indoor packing houses and food processing (§3396) means most Fresno employers are covered by at least one.
Grapes, tree fruit, and row crop operations in the San Joaquin Valley. Action level: 80°F. High heat: 95°F with mandatory cool-down breaks.
Residential and commercial construction throughout Fresno County. Framing, roofing, concrete, and site prep crews all fall under §3395.
Maintenance crews, irrigation installers, and grounds workers. One of the most frequently cited industries in Cal/OSHA heat enforcement.
Fresno's packing facilities for citrus, stone fruit, and nuts. Action level: 82°F. High heat: 87°F. The indoor rule has been enforceable since July 2024.
Distribution centers and logistics facilities without full climate control. If your warehouse reaches 82°F, §3396 documentation is required.
Food manufacturing, commercial kitchens, and other hot indoor environments in the Fresno metro. Heat-generating equipment makes 87°F easy to reach.
Yes — and the Central Valley is one of the most actively enforced regions in the state. Cal/OSHA inspects after complaints, after a heat-related illness is reported, and during random enforcement sweeps. Inspectors ask for daily temperature monitoring logs, water and shade documentation, and evidence that supervisors confirmed protocols on high-heat days. Having nothing to show is the fastest path to a citation.
Almost certainly yes. Title 8 §3396 (the indoor heat rule, effective July 23, 2024) covers any indoor workplace where workers can be exposed to heat illness risk — including packing houses, processing facilities, and any building that isn't fully climate-controlled. The thresholds are 82°F for the action level and 87°F for high heat. Fresno's summer ambient temperatures mean many facilities reach these levels without any internal heat sources at all.
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 PDF you can hand over on the spot — with server-recorded timestamps that cannot be backdated.
