Regulations and unions are still never enough no matter what you do. There must be no shortage of integrity & knowhow. The problem arises when the chemicals on site add up to a need for professional handling exceeding that which exists at the site. The top person has to actually know what to do, and actually step up to the plate and do it in complete co-operation with the ones at the front lines handling the materials. And everyone in between. Another whole level of risk management needs to focus on exposure radius when it can extend beyond the confines of the recognized hazardous site. The degree of risk relative to proximity can build to where many off-site occupants are not informed when things escalate beyond a minimal amount. Which almost never happens ideally, even when it's a purpose-built chemical facility. In an "office" building it can be a real slippery slope. Soldering a few cables or treating PCBs may not seem like a problem for an occasional prototype. And then with growth pressure you get a dozen people doing it all day every couple months. Pretty rough, but at least it's not every day and at least it's not every month. How you get there and where you go from there is really the defining characteristic.
