Biohazard vs general restoration company

What actually separates biohazard/trauma cleanup from general water, fire and storm damage restoration, and why the same company often does both.

After a trauma, a serious water event, a fire or a contamination problem, the person calling around often doesn't know whether to search for a biohazard cleanup company or a general restoration company. In practice that's often a false choice, since the same companies frequently offer both kinds of service (see below).

What matters is whether the specific job involves blood or the other materials that trigger a different set of rules, and whether the company can show it meets them.

What separates the two kinds of work

	Biohazard / trauma-scene cleanup	General water, fire, storm or mold damage restoration
What it responds to	Blood, human tissue, or the other body fluids OSHA's bloodborne pathogens standard defines	Water intrusion, fire and smoke damage, storm damage or mold growth, without a blood or body-fluid element
The framework behind it	OSHA's bloodborne pathogens standard, which governs occupational exposure to blood and a defined list of other body fluids and tissues	The restoration industry's own water-damage categories: a sewage backup, for example, is classified as "category 3" water, the most contaminated tier it recognizes

OSHA's own definition of what counts is a closed list, not an open one: semen, vaginal secretions, cerebrospinal fluid, synovial fluid, pleural fluid, pericardial fluid, peritoneal fluid, amniotic fluid, saliva in dental procedures, any body fluid visibly contaminated with blood, and any unfixed human tissue or organ. A general water, fire or storm-damage job that never touches any of that sits outside the standard the biohazard side of the table above is built around.

Often, the same company does both

SERVPRO's own site lists "Biohazard" as one of its top-level service categories, directly alongside Water Damage, Fire Damage, Mold and Storm/Disaster.

BELFOR groups it differently but keeps the same separation. Its own site places "Biohazard Cleaning Services" under Specialty Services, while Water Damage Repair, Fire Damage Repair, Mold Damage and Storm Damage Recovery sit in a separate Restoration Services group.

Which one actually applies to your job

If blood, an unattended death, a suicide, a homicide or another scene involving human tissue or body fluids is involved, the job sits under the bloodborne-pathogens framework above, no matter which name is on the van. That same OSHA standard requires employers to give exposed employees information and training on the hazard, and separately defines regulated waste. Ask for evidence of that training and ask who takes the regulated waste before anything else.

If the job is water, fire, storm or mold damage without a blood or body-fluid element, the biohazard-specific questions don't apply, and the general-restoration side of the table is what to check instead.

Either way, how to choose a remediation company covers what to ask regardless of which label the company uses for itself, who's registered to do this work covers California's specific public check, and SERVPRO, BELFOR and ATI Restoration's own company profiles show what each of those three publishes about its own history and size.
