Riverside Bio Clean covers Ontario ZIP codes 91761, 91762 and 91764, and 91758, and connects callers with cleanup companies for blood and trauma cleanup, unattended death cleanup, suicide cleanup, hoarding cleanup and meth or fentanyl residue decontamination, at homes and at work sites.

Workplace and warehouse blood cleanup in Ontario

Ontario's economy leans heavily on logistics. The city's economic development office describes more than 100 million square feet of industrial, manufacturing and distribution space. Workplaces on that scale face biohazard situations that homes do not: an injury on a warehouse floor, an assault in a parking lot, a death in a truck cab or an employee restroom.

Employers carry a duty that homeowners do not. Under the federal OSHA bloodborne pathogens standard, workers who may be exposed to blood must have protective equipment and training, so asking a general janitorial crew or a shift lead to clean up after an injury is a risk. A registered trauma scene cleanup company takes the exposure off your staff and leaves disposal records you can keep with the incident report.

  • Keep staff away from the area until it is cleaned, and note who was exposed.
  • If police are involved, wait for them to release the area.
  • Tell the cleanup company about forklifts, racking or equipment in the affected zone, and shift times.
  • Ask for the waste disposal paperwork for your records.

Company vehicles and trucks are handled the same way; ask the cleanup company whether it will work at your yard or needs the vehicle moved.

Ontario homes and rentals

Ontario's housing sits between Fontana's and San Bernardino's in age, with a median year built of 1980 and about half of homes built in 1979 or earlier. Around 58 percent of homes are owner-occupied. In the older half, cutting out drywall or trim may disturb lead-based paint in homes built before 1978, so ask the cleanup company how it handles that. Landlords with rental units should see the property managers page.

Ontario cleanup questions

Can our own staff clean up blood after a warehouse injury?

Employers must protect workers from blood exposure under the OSHA bloodborne pathogens standard, which requires training, protective equipment and an exposure control plan. Unless your staff are trained and equipped for it, a registered trauma scene cleanup company is the safer choice.

Who confirms a scene is released in Ontario?

The Ontario Police Department. Dispatch is (909) 986-6711, and the front desk for reports and other police matters is (909) 395-2001.

Can cleanup be scheduled around shifts?

Ask the cleanup company on the call. Tell it your shift times, where forklifts and racking are, and whether the area can be closed off while the work is done.

Which Ontario ZIP codes are covered?

91761, 91762 and 91764, plus 91758. The same number covers Chino, Upland, Guasti, Rancho Cucamonga and Eastvale.
