Confined Space Services

Trained crews and full safety protocols for entering, cleaning, and pumping tanks, interceptors, pits, and vaults that most contractors can't safely touch.

Licensed & Insured Trained Crews Full Safety Protocols Documented
Trained. Equipped. Safe.

Trained crews for limited-access spaces

Tanks, interceptors, wet wells, pits, and vaults are classified as confined spaces — areas with limited entry, poor ventilation, and the potential for hazardous atmospheres. Entering them without proper training, monitoring, and equipment is dangerous and, in most cases, illegal. These jobs demand a crew that follows strict safety procedures every single time.

JN Grease Service performs confined-space entry, cleaning, and pumping with trained personnel, atmospheric monitoring, and the right protective and rescue equipment. We get the job done safely and completely, then document the work — so a difficult, high-risk task is handled the right way.

Why It Matters

Why Confined Spaces Demand Specialists

Real hazards

Toxic gases, low oxygen, and engulfment risks make untrained entry genuinely life-threatening.

Strict regulations

Confined-space entry is governed by safety rules requiring training, monitoring, and permits.

The right team

Safe entry needs trained crews, atmospheric testing, and rescue-ready equipment — not just a ladder.

Where we provide confined-space service

Storage tanks

Entry, cleaning, and pumping of above- and below-ground tanks.

Interceptors

Large in-ground grease interceptors requiring internal access.

Wet wells & pits

Lift stations, sumps, and pits that need evacuation and cleaning.

Vaults & manholes

Below-grade structures with limited, hazardous access.

Sludge & residue

Heavy buildup that has to be removed from inside the structure.

Emergency entry

Urgent situations requiring safe, rapid confined-space response.

Transparent Pricing

What Affects Your Cost

Confined-space work is priced around the space, the hazards, and the scope. Here's what we factor into your quote.

Space type & size

The structure and how much has to be cleaned or pumped inside it.

Hazard level

Atmospheric and other hazards determine the safety setup required.

Crew & equipment

The number of trained personnel and the gear the entry demands.

Volume of material

How much sludge, residue, or liquid needs to be removed.

Access

Difficult or below-grade access adds time and equipment.

Scheduling

Recurring or planned work is more efficient than emergency calls.

Safety is never an upsell. Full protocol — testing, monitoring, ventilation, and rescue readiness — is included on every confined-space job, because that's the only way it should be done.
