In a city with frequent building turnover and ongoing projects, exposures can be easy to overlook at first. A release might occur during maintenance, a strong odor could be noticed by multiple people, or symptoms might start after a shift, a transit delay, or time spent indoors while work is happening.
In Massachusetts, insurers and defendants commonly push back on:
- How soon symptoms began after the exposure
- Whether the substance was the one tied to your diagnosis
- Whether other factors (seasonal illness, asthma, irritant exposure from everyday activities) explain your symptoms
That’s why early legal guidance matters: it helps you build a clean timeline while memories are fresh and records are still obtainable.
