Understanding Fire Protection Regulations in Wisconsin

Wisconsin businesses must adhere to stringent fire safety standards set by the National Fire Protection Association (NFPA) and enforced by the state Department of Safety and Professional Services (DSPS), along with local fire authorities. Thanks to improved regulations and rigorous enforcement, fire-related fatalities in Wisconsin have declined dramatically—by nearly 50% over the past three decades. However, fire inspectors regularly uncover common violations that pose serious risks.

Below, we highlight the most frequently encountered fire protection code violations in commercial and industrial facilities and provide practical strategies to help your business avoid them.

Common Fire Protection Code Violations & Solutions

1. Lapsed Fire System Maintenance

Violation:
  • Fire alarm systems not tested annually (weekly self-tests required in Milwaukee)
  • Portable extinguishers not professionally serviced annually

  • Schedule yearly inspections for alarms, sprinklers, and extinguishers
  • Maintain dated inspection tags and detailed maintenance records on-site

Properly maintained extinguishers can successfully extinguish up to 80% of fires in their initial stages.

2. Blocked or Improper Exits

Violation:
  • Exits obstructed by storage, furniture, or equipment
  • Locked, chained, or propped-open exit and fire doors

  • Regularly inspect exit routes to ensure they remain clear and accessible
  • Keep exit signage and backup lighting functional
  • Ensure fire doors are never wedged open unless equipped with automatic hold-open devices tied to the fire alarm system

Historically, blocked exits are a leading cause of casualties during fires.

3. Improper Use of Extension Cords and Electrical Hazards

Violation:
  • Extension cords used as permanent wiring
  • Daisy-chained or damaged cords
  • Cluttered electrical rooms with insufficient clearance

  • Use extension cords strictly for temporary purposes
  • Hire an electrician to install additional permanent outlets
  • Maintain at least a 36-inch clearance around electrical panels and equipment

Regularly inspect and immediately remove damaged or frayed cords to prevent potential fires.

4. Fire Doors Not Functioning or Propped Open

Violation:
  • Fire doors propped open or without functional self-closing mechanisms
  • Door closers disconnected or tampered with

  • Ensure all fire-rated doors have working self-closers
  • Train staff never to prop open fire doors or disable closers
  • Immediately remove any wedges or obstructions found in doors

Properly functioning fire doors significantly slow the spread of smoke and fire, protecting escape routes.

5. Storage and Housekeeping Violations

Violation:
  • Insufficient clearance below sprinkler heads (less than 18 inches)
  • Storage of combustible materials or flammable liquids improperly located
  • Accumulation of trash, especially near ignition sources

  • Clearly mark maximum storage heights below sprinkler heads
  • Store flammable liquids in approved fire-resistant cabinets
  • Maintain daily housekeeping routines to remove trash and combustible materials

Sprinklers require at least 18 inches of clearance below them to effectively disperse water during a fire.
