Malden residents may encounter hazardous chemicals during:
- Apartment and building remediation (repairs, cleanup, sealing, or restoration after leaks)
- Turnover work where products are stored, mixed, or applied quickly to meet deadlines
- Construction and renovation near busy streets and public access areas, where ventilation can be inadequate
- Maintenance of older buildings where past materials and hidden hazards complicate cleanup
- Third-party vendor work—when a contractor’s practices affect tenants, neighbors, or workers
In many of these situations, the exposure is discovered after symptoms begin—or after someone realizes that the “strong odor” or visible fumes weren’t normal.
