Certified Confined Space Entry for Flour, Grain & Starch Silos
Audit-Ready Silo & Storage Hygiene
24/7 Emergency DispatchService Overview
Flour, grain, and starch silos are OSHA-classified permit-required confined spaces. Cross-contamination, mold growth, and insect debris inside storage vessels are major AIB and SQF audit deficiencies. Our certified confined space teams deliver dry and wet FSMA-compliant sanitation — documented for every audit cycle.
Key Benefits
OSHA 1910.146 Compliance
Written entry permits, atmospheric testing, LOTO procedures, and certified entry teams on every job — no shortcuts.
Cross-Contamination Elimination
Full interior sanitation removes allergen residue, mold, and product buildup that cause audit deficiencies and product recalls.
Dry & Wet Methods
We select the appropriate sanitation method (dry vacuuming, pressure washing, chemical application) based on your stored product and vessel type.
FSMA-Ready Documentation
Atmospheric test logs, entry permits, before/after photos, and cleaning records are provided after every job.
Our Process
Permit Authorization
A written confined space entry permit is issued, documenting all hazards, atmospheric test results, and emergency protocols.
Atmospheric Testing
Continuous multi-gas monitoring for oxygen levels, flammable gases, and toxic contaminants before and during entry.
Lockout/Tagout (LOTO)
All energy sources — augers, conveyor belts, pneumatic lines — are locked and tagged out before any entry.
Interior Sanitation
Dry or wet sanitation is applied to all interior surfaces. A final inspection confirms audit-ready cleanliness.
