Distillation Equipment Safety Inspection Checklist [FREE PDF]

Distillation equipment inspections are governed by TTB 27 CFR Part 19 (Distilled Spirits Plants), which mandates strict operational and safety standards for all stills, condensers, and spirit-receiving vessels. OSHA 29 CFR 1910.119 Process Safety Management rules apply to distilleries handling flammable liquids above threshold quantities, requiring documented process hazard analyses and mechanical integrity programs. FSMA Preventive Controls under 21 CFR Part 117 further require that equipment u

Pre-Run Safety and Compliance Check

Confirm all regulatory, safety, and operational prerequisites are satisfied before initiating distillation.

• Is the current TTB distilled spirits plant (DSP) permit valid and posted in a visible location within the distillery?
• Have all pre-run equipment logs, maintenance records, and prior inspection findings been reviewed by the operator?
• Are all distillation operators trained and certified on process hazards specific to flammable alcohol vapor handling?
• Is the distillery's Process Hazard Analysis (PHA) current (within 5 years) and available for reference?
• Are emergency shutdown procedures posted at the still and confirmed understood by all on-shift personnel?

Still Structural Integrity Inspection

Inspect the pot still, column still, or hybrid still for physical integrity, seal condition, and pressure safety.

• Is the still body free of visible cracks, pitting, corrosion, or weld fatigue that could compromise pressure integrity?
• Are all manway gaskets, sight glass seals, and copper joints free of leaks and confirmed properly torqued?
• Is the still pressure relief valve (PRV) inspected, undamaged, and confirmed to open at the correct set pressure?
• Are all column plates or packing materials in column stills verified as intact with no blockages or channeling?
• Is the still properly insulated where required, and are all insulation covers intact without gaps or moisture ingress?
• Is the still correctly grounded and bonded to prevent static electricity buildup during alcohol vapor transfer?

Condenser and Worm Tub Inspection

Inspect the condenser, worm tub, cooling water system, and vapor line for proper function and product safety.

• Is cooling water flow to the condenser confirmed at adequate flow rate and entering at or below the required inlet temperature?
• Is the condenser shell and tube bundle free of visible fouling, mineral scale, or blockages that could reduce heat transfer efficiency?
• Are condenser inlet and outlet temperatures monitored and recorded within the expected operational range?
• Is the vapor line from still head to condenser free of obstructions, properly sloped for drainage, and showing no signs of vapor leakage?
• Is the condenser outlet spirit temperature measured and within the acceptable range for product quality and flash point safety?

Spirit Receiver and Distillate Cuts Verification

Verify spirit receiving vessels, parrot, and cut selection processes are compliant with TTB requirements and product safety standards.

• Is the spirit receiver vessel clean, properly labeled with batch number, and constructed of food-grade stainless or copper material?
• Is the distillate parrot (spirit safe) clean, calibrated, and hydrometer functioning correctly for accurate proof measurement?
• Are foreshots being collected separately and confirmed removed from the product stream before hearts collection begins?
• Are distillate cuts (foreshots, heads, hearts, tails) documented with time, proof, and volume for TTB records?
• Is new make spirit proof measured, recorded, and within the TTB-regulated maximum proof for the spirit class being produced?

Flammability and Fire Safety Controls

Inspect all fire prevention, detection, suppression, and flammable vapor control systems in the still house.

• Are fixed flammable gas / alcohol vapor detectors calibrated, alarming correctly, and readings below 10% LEL at pre-run check?
• Is all electrical equipment in the still house rated for Class I Division 1 or Division 2 hazardous locations?
• Are fire extinguishers (rated minimum 40-B:C) located within 50 feet of all still operating positions and inspected within the last 30 days?
• Is automatic fire suppression system (sprinkler or CO2) in the still house confirmed operational with no deactivated zones?
• Is ignition source control enforced including prohibition of open flames, smoking, and hot work within the distillation area during operations?
• Is facility ventilation system operational, providing adequate air exchanges to prevent flammable vapor accumulation in the still house?

Heating System and Energy Source Inspection

Inspect direct fire, steam, or electric heating systems powering the still for safe and regulated operation.

• Is the steam boiler or heat exchanger supplying the still operating within its rated pressure and temperature parameters?
• Are all steam lines, valves, and traps insulated, free of leaks, and showing no signs of water hammer or vibration damage?
• If direct flame heating is used, are burners operating correctly with no signs of flame impingement on structural members?
• Is the heating rate control system (temperature controller or steam regulator) functional and setpoints verified for current batch?
• Are high-temperature alarms and automatic cutoff systems for the heating source tested and confirmed operational?

TTB Regulatory Compliance and Record Keeping

Verify TTB-required gauging, bonding, and production record requirements are met throughout the distillation run.

• Are all distillation gauging instruments (hydrometers, proofing equipment) TTB-certified and within calibration date?
• Is the TTB production record (Form 5000.51 or equivalent) being completed in real time with all required production data?
• Are spirit losses (tails, foreshots, spills) documented and within acceptable variance limits for TTB reporting?
• Are bond amounts current and adequate to cover spirits in process and in storage at the distilled spirits plant?
• Were any equipment defects, process deviations, or safety incidents identified during this distillation run?
• Please document any corrective actions taken, deviations noted, or follow-up maintenance required from this inspection.
