Stop the source only if it is safe, keep people away and call 911 if there is fire risk or danger. A cleanup team contains the leak, removes soaked material and cleans pavement and equipment. It can also provide records for the insurer.
OSHA sets safety rules for workers who respond to and clean up hazardous substances. Professional crews follow those rules and use gear matched to the hazard. Employers have their own duties, which safety staff or an attorney can explain.
Ask what training the crew has, how waste is managed and what records you get. Request references and a clear description of the steps. Then decide whether the company fits your site.
Crime scene crews mainly use detergents and EPA-registered disinfectants against germs, not harsh industrial chemicals. Hazmat crews choose products to match the hazardous material instead. Products are never mixed, and labels set the contact time.
Small spills of familiar products may be manageable by following the label. Large, unknown or dangerous spills are not. Never mix products. If in doubt, leave the area, keep people and pets out and call 911 or Poison Control.
Calls are answered 24/7, and the work is kept discreet.
