Indoor environmental emergencies can happen without warning — and fast action is critical to prevent minor problems from becoming major health and property risks.

Common causes of emergency damage include:

• Plumbing leaks and pipe bursts
• Roof leaks during storms
• Overflow from appliances like dishwashers, washing machines, and water heaters
• HVAC-related floods, such as condensate line failures
• Groundwater intrusion after heavy rains
• Sewer line backups

In every case, the goal is the same: stop the source of damage as quickly and safely as possible, minimize water spread, and protect indoor environmental health.

Throughout this section, we’ll walk you through simple, practical steps to respond effectively in the critical first hours after an event.
