Supporting Kern County's massive farming economy requires rugged, compliant sanitation built for the fields. We provide expert agricultural portable toilet rental in Bakersfield CA, supplying trailer-mounted restrooms specifically designed for growers and harvest crews. Farm labor contractors face constant pressure from Cal/OSHA Title 8 inspections and the logistical nightmare of maintaining clean field hygiene. We handle the heavy lifting with certified, fully stocked field toilets and mobile washing setups that move seamlessly with your crew.
Section 3457 requires more than just dropping a porta potty in the field. The standard mandates separate toilet facilities for each sex for every 20 employees or fraction thereof engaged in hand-labor operations. A mixed crew of 40 needs at minimum 2 units for women and 2 for men — not 2 total. Handwashing facilities are required alongside every toilet unit — one station per 20 workers. And all of this must be within a quarter mile or 5-minute travel time of where workers are working.
Kern County is the third-largest agricultural producer in the United States by value. Grape harvest in Arvin and McFarland runs August through October. Citrus picking runs October through March. Almond harvest hits in August. Pistachio harvest peaks in September and October. We plan deployments around those windows — not around what's convenient for our service schedule.
Cal/OSHA inspectors can and do conduct field inspections during harvest season. Violations of Section 3457 carry a minimum civil penalty of $750 per violation. We provide the Cal/OSHA Form 46C documentation you need as part of every agricultural account — at no extra charge.
National porta potty brokers know what construction OSHA requires. Most don't know Section 3457 from Section 3364. Section 3364 covers non-hand-labor agricultural operations while Section 3457 covers the crews actually picking fruit. We do. If you're managing a harvest crew in Shafter or a vineyard in Arvin, that distinction determines what you're required to provide.
Here's the version you need before the inspector shows up — not what a national rental company's FAQ says. What the regulation actually says.
| Regulation | Requirement |
|---|---|
| Cal/OSHA Title 8 §3457 | Toilet count, handwashing, placement, records for hand-labor ag operations |

| CA Labor Code §6712 | FLC joint liability — contractor may be responsible for compliance |
| Cal/OSHA Form 46C | Field Sanitation Compliance Form — required documentation for cited employers |

Every agricultural operation type has specific Section 3457 compliance considerations. Select your operation type below.
Grape harvest in Arvin and McFarland runs August through October — Kern County's highest-volume labor period. Hand-harvesting crews require Section 3457-compliant separate-sex facilities at or within a quarter mile of every active block. We carry standby inventory specifically during this window. Priority dispatch available for harvest accounts with 24-hour response.
Almond harvest peaks in August; pistachio in September and October. These operations often involve combination hand-labor and mechanical shaking crew types — determining whether Section 3457 or Section 3364 applies depends on what each crew type is specifically doing. We help growers pre-determine the correct standard before deployment to avoid citation risk.
Citrus picking in Kern County runs October through March — a cross-season deployment that often continues while other operations are winding down. Carrot harvest is essentially year-round. These are hand-labor operations fully subject to Cal/OSHA Section 3457. Running-water handwashing is particularly important for pesticide and agrichemical-adjacent field work.
Farm labor contractors in California face joint liability with growers for Section 3457 compliance. Under California Labor Code Section 6712, an FLC who contracts in advance of production and exercises substantial control may be considered an "agricultural establishment" under Section 3457 — meaning the compliance obligation can fall on the FLC, the grower, or both. We set up accounts by site, with service records maintained per grower location under a single FLC contract.
A unit breaks down during harvest. A Cal/OSHA inspector shows up and finds a unit out of service. A late-season crop comes in faster than expected and the crew doubles overnight. Agricultural field emergencies don't happen 9 to 5. We run a live emergency dispatch line at (661) 605-7813. Agricultural accounts with an existing relationship get priority dispatch. We carry standby inventory during August through October specifically because unit shortfalls during harvest are common and costly.
Kern County's harvest schedule determines your compliance window. We plan your units around these windows — not around what's convenient for our service routes.

"We had a national company drop standard construction toilets. Inspector showed up and pointed out they didn't meet Section 3457 minimum specs. $750 citation."
What We Do Differently: We deliver units that meet the 8 sq ft minimum and separate-sex requirement. We know which standard applies before we load the truck.
"Our foreman had to translate for the service crew every week. Half the time nobody showed up because dispatch couldn't confirm the address."
What We Do Differently: We run Spanish-speaking dispatch for agricultural accounts. Section 3457(b)(4) requires employee notification — we support that communication chain.
"We got cited and needed 5 years of annual written statements. The previous company didn't keep our service records. We had nothing to show."
What We Do Differently: We maintain written service records per site, per account. Cal/OSHA Form 46C documentation included. 2-year retention is our standard practice, not an add-on.
Proven success delivering Cal/OSHA Section 3457 compliant sanitation across Kern County's agricultural operations.
"We had a Cal/OSHA inspector show up during grape harvest in McFarland. Our units were placed within the quarter-mile requirement, we had the separate-sex count right, and they handed us the compliance paperwork for Form 46C on the spot. No citation. These guys know Section 3457 — most companies don't."
"As an FLC operating across Arvin and Shafter, I needed one account that could handle multiple grower sites. They set us up by site, maintained records per location, and their Spanish-speaking dispatch made coordination with our crews seamless. I've worked with three other Bakersfield companies and none of them understood the FLC compliance structure the way these guys do."
"During almond harvest in Shafter, one of our units went down. I called at 6:30 AM and they had a replacement on-site by 11. During the Aug–Sept peak window when every other company says 'we'll get to you next week.' That emergency response is why we stayed with them year-round."
