Chemical Storage & Spill Readiness

OSHA HazCom + EPA-aligned audit of chemical storage rooms, secondary containment, labeling, SDS access, and spill response capability.

Storage Room Conditions

• Chemical storage room is secured, posted, and access is limited to authorized personnel
  Verify the room is controlled to prevent unauthorized access and any required hazard signage is visible at the entrance.
• Floor, shelving, and storage surfaces are clean, dry, and free of residue or incompatible materials
  Look for spills, crystallization, corrosion, damaged shelving, or evidence of incompatible chemical contact.
• Ventilation is present and operating as intended for the stored chemical hazards
  Confirm ventilation is not blocked and any required mechanical ventilation is functioning.
• Incompatible chemicals are segregated by hazard class
  Check segregation of acids, bases, oxidizers, flammables, toxics, and water-reactives as applicable to site inventory.

Labeling & SDS Access

• All primary and secondary containers are labeled with product identity and hazard information
  Confirm labels are legible, intact, and consistent with the chemical identity in use.
• Secondary container labels are present where required and not handwritten in a way that obscures hazard communication
  Verify spray bottles, transfer containers, and decanted containers are labeled per site HazCom procedure.
• Safety Data Sheets are immediately accessible to employees during all shifts
  Confirm SDS access is available without delay via paper binder, kiosk, or electronic system and is usable by employees in the area.
• Current SDSs are available for chemicals stored in the area
  Check that the SDS library includes the chemicals actually present and that outdated or missing SDSs are identified.

Secondary Containment & Storage Controls

• Secondary containment is provided where required and appears sized to the stored containers
  Verify trays, berms, cabinets, or sumps are present for liquid chemicals and are not cracked, overloaded, or bypassed.
• Containment capacity appears adequate for the largest foreseeable release
  Document whether containment is visibly sufficient for the stored volume and container arrangement; note any overflow risk.
• Chemical containers are closed, intact, and stored upright unless designed otherwise
  Check for leaking caps, bulging containers, corrosion, or unstable stacking.
• Flammables and other regulated materials are stored in approved cabinets or locations as required
  Verify storage method matches the hazard class and site procedure, including cabinet condition and door closure.

Spill Response Capability

• Spill kit is present, accessible, and appropriate for the chemicals stored in the area
  Verify absorbents, neutralizers, disposal bags, tools, and PPE match the hazards present.
• Spill kit contents are complete and not expired or depleted
  Check inventory against the site standard and note missing, damaged, or used items.
• Emergency eyewash and shower equipment is accessible and unobstructed
  Confirm access paths are clear and equipment can be reached quickly from the storage area.
• Employees can describe the spill response notification and escalation process
  Verify workers know when to isolate the area, notify supervision, and contact emergency response resources or the AHJ as required.
