Plumbing Systems Verification

Check water supply connections for proper installation
Test water pressure at all fixtures for adequacy
Inspect all visible plumbing lines for leaks or damage
Test all drains for proper flow and absence of backups
Verify toilets flush properly and have no leaks
Check sinks and faucets for function and leaks
Test hot water system if applicable
Inspect sewage connections for security and leaks

Fire & Life Safety Assessment

Test smoke detectors for proper function
Check carbon monoxide detectors if applicable
Verify fire extinguishers are present and accessible
Check fire extinguisher inspection dates and pressure
Inspect emergency exit signage for visibility
Verify exit doors are unobstructed and operational
Check that emergency evacuation plans are posted
Test sprinkler system components if equipped
Verify fire alarm systems function if installed
Document any fire safety issues with photos

Accessibility & Site Conditions

Measure ramp slopes for ADA compliance (1:12 max)
Verify doorways provide minimum 32" clearance
Check restroom facilities for ADA compliance if required
Inspect grab bars for proper installation and security
Verify door hardware is accessible (lever-type preferred)
Measure paths of travel for minimum 36" clearance
Check walkways for trip hazards and adequate lighting
Inspect signage for proper display and legibility
Verify tie-downs/anchors are secure if applicable

Safety Pro Tips

Seasonal Inspection Focus: Adjust your inspection emphasis based on seasons—check heating systems before winter, cooling systems before summer, and roof/water intrusion points before rainy seasons.
Documentation Matters: Take dated photos of issues found during inspections to track deterioration over time and justify repair requests.
Involve Occupants: Interview trailer occupants during inspections as they often notice developing problems in their daily use that might not be apparent during a brief inspection.
Coordinate with Site Activities: Schedule inspections to minimize disruption while ensuring access to all areas—early morning or end-of-day inspections often work best.
Prevent Water Damage: Pay special attention to seals around doors, windows, and roof penetrations as water intrusion is the leading cause of trailer deterioration.

Critical Safety Procedures

Emergency Response Planning: Ensure emergency evacuation plans are posted at each exit and all occupants know the assembly point location.
Weather Event Preparation: Secure loose items around the trailer's exterior before high winds and check tie-downs/anchors before severe weather events.
Fire Prevention Measures: Prohibit space heaters without tip-over protection and maintain 3-foot clearance around all heat-producing equipment.
Indoor Air Quality Management: Replace HVAC filters according to schedule and address water intrusion immediately to prevent mold growth.
