Glossary

Biohazard - Any type of biological waste or biological agent, such as a virus, that can be a threat to humans. Biohazards must be eliminated by professionals such as Bio-One, otherwise they can cause serious health effects. Continuous exposure to biohazards, if not properly removed, can lead to long term adverse health effects.

Biohazardous Agent - A biological agent or condition (an infectious organism or insecure laboratory procedures) that is a hazard to humans or the environment.

Biohazard Remediation - The cleanup and disinfection of any biohazard situation: hoarding, commercial or industrial accidents, chemical spills, contamination scenarios. 

Biological Waste - Any material that contains or has been contaminated by a biohazardous agent.

Crime Scene Cleanup - Cleanup and disinfection of blood, other bodily fluids, and other potentially infectious materials from a crime scene. (OPIM)

Cleanup Operation - When hazardous substances are removed, confined, stabilized, or in any other manner taken care of; the end goal being to make the scene safer for people or the environment.

Decontamination - The removal of hazardous substances to avoid or minimize potential dangerous health effects. 

Hazardous Materials Response (HAZMAT) - An organized group of trained professionals who handle and control hazardous substances; quite often, requiring very close proximity to the substance.

Diego and team are fantastic. They are smart, hard-working, respectful, and kind. I had a hoarding cleaning - they worked with my limits, found things I needed them to find, found other things (a passport!) that I hadn't even asked them to find, and in 2 days transformed my house from a toxic site to a home. Part of my direction was to save all photos, books, and paperwork. It took longer, but they stacked them neatly around the edges, by category, making it much easier for me to deal with them. I heartily recommend Bio One of San Francisco. They are safe to work with and worth the money!

If you've ever seen the show hoarders, then you need a team like this one to help you out. Diego and his team were hard-working, communicative every step of the way and very understanding/compassionate throughout the whole cleanup process. The project we hired them for was easily worse than many of the hoarders episodes. Tons and tons (literally) of e-waste, biohazard waste, and things that would condemn a home in a heartbeat. They didn't bat an eye and did everything from junk removal, biohazard remediation, to deep cleaning of the home. They brought a 40 cubic yard dump truck and hauled away 5 dump trucks worth. Every day was a noticeable achievement. What we thought was an insurmountable project suddenly became doable. And most of all, the amount of burden Diego and his team lifted off our shoulders (literally and figuratively) was incredible. Given the scope of work and our timeline (mine, not Diego's) we stopped about 2/3 of the way through and hope to have Diego and his team back out on site later in the year to finish up the remaining 1/3. 100% would recommend his team to anyone.

Miracle workers! This team did such a great job — they were helpful, professional, really good communicators, and very detail-oriented. I'm very detail-oriented myself and it takes one to know one.😉 Can't recommend them enough!

Diego and his crew were so kind and helpful during our time of loss. They did such a wonderful job cleaning and disinfecting the area. It was a pleasure working with people who make a difficult time so much easier. I strongly recommend Bio-One of San Francisco for this specific type of cleaning.

Diego was really easy to work with. Got a fair quote, that was clearly spelled out. Work was done thoroughly and on time. Communication was easy. Highly recommend.

I highly recommend Bio-One of San Francisco. I felt overwhelmed by the enormity of the job I had and Diego reassured me every step of the way. Diego and the crew exceeded every expectation I had and were incredibly professional and thorough. I would highly recommend Bio-One of San Francisco to absolutely anyone who needs help with a cleanup!
