Fire risks and hazards
• Abnormally high fuel loads.
• Higher density of materials = greater opportunity for ignition and
increases fire intensity.
• Blocked or impeded access/egress.
• Unorthodox items.
• Unorthodox use of utilities =
unsafe cooking and heating.
• No working smoke alarms.
5
Addressing the risk
• Improve operational response.
• Improve system for directing persons to appropriate
treatment and services.
• Enhance risk reduction advice.

To test the hypothesis of greater fire risks being
associated with hoarding.
