Environmental Services

Keep your property safe and clean, no matter what.

Protect your property and its occupants from hazardous materials with our environmental and bio-response services. Our certified teams will help you manage hard-to-clean hazards like oil spills, fuel spills, chemical spills, hazardous substance contamination and other complex biohazard events.

Your safety is our first priority. We take the necessary steps to ensure that everyone on site is safe at all times. This includes wearing the correct personal protective equipment (PPE), containing the contaminated area, and properly packing out hazardous materials to avoid impact on surrounding areas.

We respond to environmental and biohazard incidents with teams that hold certifications in cleaning complex and often hazardous situations. This allows us to ensure that your property will be a safe environment for you and your occupants when our work is complete.

Spills, waste and pathogens can quickly spread to surrounding areas and can pose a major health threat if neglected. We thoroughly inspect the areas surrounding the incident, so nothing is missed during the recovery process.

Our environmental and biorecovery services are designed to support you at every stage of your recovery process. Our services include mitigation and reconstruction. Your dedicated agent will remain in contact with you as we mitigate, remediate and restore your property to its previous state.

Let us help you prepare for the unexpected

When disaster strikes, knowing what to expect can make a world of difference. Discover what our specialists have to say about preparing for disaster, expediting recovery, and everything in between. We’re here to help, always.


First Onsite is equipped to handle a variety of small-scale environmental spills, including those involving fuels like diesel or gasoline, chemicals, sewage, oils and agricultural substances.

We offer 24/7 emergency response and aim to be onsite quickly. The exact timing can depend on factors such as the project’s location and the incident’s severity. It is important to note that not all services are available throughout North America. Please contact us for more information.

Safety is our top priority. Our teams adhere to strict training and safety protocols to protect both the employees and occupants of the space. They wear appropriate protective equipment and employ methods that meet or exceed industry and regulatory standards.

While each spill is unique, the general process includes assessing the risk associated with the release, containing it to prevent further spread, removing the spilled substance, cleaning and restoring the affected area, disposing of waste according to applicable laws, and monitoring the site for any ongoing impact.

Bio recovery is the act of assessing risk, mitigating threats, and remediating conditions resulting from the release of biological hazards. This may include crime and trauma mitigation (bloodborne and bodily fluids); suicide cleanup; and response to zoonotic diseases, foodborne diseases, public health threats, illicit drugs and clandestine drug labs.

Yes, we maintain strict compliance with all local, regional and national environmental regulations and guidelines. Our cleanup processes are designed to meet and exceed these standards.

According to the United States Occupational Safety and Health Administration (OSHA), a hazardous substance is any substance that is “designated or listed under paragraphs (A) through (D) of this definition, exposure to which results or may result in adverse effects on the health or safety of employees” [29 CFR 1910.120(a)(3)].
Response to such events triggers training of site visitors according to what is known as the OSHA HAZWOPER [29 CFR 1910.120] standard or Hazardous Waste Operations and Emergency Response. They include the following:
A. Hazardous Substances as defined under the Comprehensive Environmental Response, Compensation and Liability Act. This was also known as Superfund. The USEPA defines which chemicals and processes generate them. These chemicals, and the sites that generate them, can cause acute and latent harm to the environment and human health.
B. “Biological agents” and “other disease-causing agents,” exposure to which can lead to death, disease, behavioural abnormalities, cancer, genetic mutation, physiological malfunctions or physical deformations. These range from environmentally significant biological releases to substances that could be presumed to have, or are known to contain, a biohazard.
C. “Hazardous materials event” as defined by the US DOT This can be a release of gasoline, other fuels, acids, caustics, solvents or chlorine. These events tend to happen when there is a transportation accident. The DOT defines their own Hazardous Materials Regulations (HMR); and all response teams are subject to HAZWOPER for emergency mitigation and or remediation.
D. “Hazardous waste” as defined. OSHA defines “hazardous waste” as the waste form of a “hazardous substance”; that is, a substance that will, or may, result in adverse effects on the health or safety of employees. First Onsite manages all customer generated hazardous waste according to national and local government laws. This includes the management of waste from the mitigation of releases of hazardous substances. The USEPA generates waste codes for the purposes of tracking hazardous waste from a cradle-to-grave process called the Resource Conservation and Recovery Act (RCRA)

Also known as biohazards, this term refers to biological substances that pose a threat to the health of living organisms, primarily that of humans. These can include medical waste or samples of a microorganism, virus, or toxin (from a biological source) that can affect human health. It can also include substances harmful to other animals.

Hazardous substance release cleanups are required for various situations, including crime or trauma scenes, infectious disease contamination, industrial accidents, sewage backups, and fuel and chemical spills.

All hazardous and biohazardous waste is properly packaged, transported, and disposed of at licensed waste facilities in compliance with local and federal laws.
