Keeping our laboratory safe and compliant is our top priority. Our unit manages biohazard risk assessments, safety audits, and emergency response plans that surpass OSHA, CDC, and BMBL guidelines.

Biosafety & Chemical Safety

We take a comprehensive approach to safety, covering both biological and chemical hazards. Our Biosafety and Biosecurity Manual outlines procedures for handling biological materials safely, while our Chemical Safety Program ensures proper storage, labeling, and disposal of hazardous chemicals.

  • Risk assessments to identify and mitigate potential hazards.
  • Personal protective equipment (PPE) guidelines tailored to biological and chemical risks.
  • Training & compliance programs to keep staff informed and up to date.
  • Emergency protocols for spills, exposures, and other incidents.

Incident Reporting & Emergency Response

Quick reporting of incidents, near misses, and spills is essential to maintaining a safe laboratory environment. Our Incident Response Program provides clear protocols for handling various emergencies, including medical incidents that require first aid or emergency contact assistance, spill response procedures for both biological and chemical materials, and critical safety measures for active shooter situations and shelter-in-place events.

Respiratory Protection Program

For areas with airborne hazards, our Respiratory Protection Program ensures that respirators are properly selected and fit-tested, that personnel undergo medical evaluations to confirm safe use, and that they receive training on how to wear and maintain their equipment correctly.

Packaging & Shipping Guidelines

Safe transportation of infectious substances is critical. We offer 6.2 Hazardous Materials Shipping Training for in-house employees and our supporting sentinel labs. Our in-house trainer is also available to answer any questions about compliance and best practices.
