I'm thinking of potentially sabotaging my former boss's business because of health risks within the building.
What type of health risks does the building have?
They have toxic mold in the building. It's awful.
That is very wrong. Employers are supposed to provide a safe place of employment. You are right to report health violations.
I'm going to take my time to decide on doing this.
I understand wanting to think it over because it's a big deal to come forward with something like that, but I urge you to do it as soon as you can. The employees who work there are suffering and may have long term issues because of the mold. It's important that health officials learn about this as soon as possible.
