63,134 farms operate in California, and nearly every one runs outdoor field labor, indoor packing, or both — meaning most are covered by at least one Cal/OSHA heat rule. Harvest crews, dairy operations, packing houses, and farm labor contractors all carry the same documentation burden. HeatLog checks the forecast at each ranch or facility every morning and builds your compliance record automatically, so it's already done before anyone asks.
HeatLog monitors the weather at every ranch, field, or facility address, 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 field, ranch, or facility address you add — the same government data a Cal/OSHA inspector can independently verify. Add unlimited sites across scattered acreage or multiple properties.
Your crew supervisor or foreman gets an email alert with a one-click compliance checklist: shade, water, cool-down breaks, buddy system. On high-heat days, mandatory cool-down periods are logged automatically. Takes under 60 seconds to confirm — no login required.
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 at the ranch gate or packing house on the spot.
California grows more than 400 commodities, and heat coverage isn't limited to row-crop harvest — orchard and vineyard work, dairies, packing floors, and the labor contractors who staff all of them each carry their own documentation exposure.
California grows roughly 80% of the world's almonds. Shaking, sweeping, and harvest crews work orchard floors through late-summer heat — squarely covered by §3395's 80°F action level and 95°F high-heat provisions.
Lettuce, strawberries, tomatoes, and other row-crop harvest labor in the Central Valley, Salinas Valley, and Imperial Valley — hand-harvested crews with the highest per-worker heat exposure of any ag segment.
San Joaquin Valley cotton operations run field and irrigation crews through peak summer temperatures well above the 95°F high-heat threshold, with mandatory cool-down and buddy-system documentation required.
FLCs and growers using H-2A seasonal labor carry the same §3395 liability as the grower — often across multiple ranches in a single day. Documentation has to travel with the crew, not sit at one fixed address.
Citrus, grape, and tree-fruit packing floors frequently reach the 82°F §3396 action level in staging and receiving even with cold storage present — the rule covers every area workers occupy, not just the cold side.
Dairy and livestock operations statewide, plus outdoor and greenhouse cannabis cultivation — an increasingly inspected segment as licensed acreage has grown, and one many operators don't realize falls under §3395.
Add every ranch, field, or facility address as its own site — there's no limit, and each site gets its own independent morning forecast check and compliance record. If your crews move between properties during the week, each location's record stands on its own, so you're covered no matter which ranch an inspector shows up to, even if it isn't the one you own.
Yes. §3396 covers every area where workers are present, not just non-refrigerated zones. If your staging, receiving, or packing floor reaches 82°F even though cold storage nearby is at 34°F, that floor is independently subject to §3396 documentation requirements — a detail that surprises many packing operators who assume proximity to cold storage exempts them.
Yes — California has a dedicated agricultural heat-enforcement program, and harvest season brings both complaint-driven and proactive inspections across the Central Valley, Salinas Valley, and Imperial Valley. Agriculture's combination of outdoor field exposure, indoor packing/processing exposure, and a history of heat-related worker deaths makes it a consistent, year-round enforcement priority — not a seasonal afterthought.
