Safety

Disposal & Waste Management

In the clinical laboratory, the analytical process is only half the job; the safe management of the resulting byproducts is equally critical. Waste management is governed by a complex web of federal regulations (EPA, OSHA, DOT) designed to protect public health and the environment. A failure in this system - whether it be mislabeling a bottle or putting a needle in the trash - can result in severe injury to support staff or massive regulatory fines

Proper Waste Disposal

The foundation of waste safety is Identification

  • Labeling: Every container must be clearly labeled in English with its full contents (no abbreviations) and hazard class. “Unknowns” are dangerous and costly
  • Transport: Moving waste requires secondary containment (carts/bins) to prevent spills. Off-site shipping is strictly regulated by the DOT, requiring UN-certified packaging and trained personnel

Regulated Medical Waste

This category includes infectious materials like blood, cultures, and sharps

  • Color Coding: Use Red Bags for soft infectious waste and rigid Sharps Containers for needles and glass
  • Sharps Safety: Never recap needles. Dispose of them immediately. Never overfill a sharps bin past the “Max Fill” line
  • Treatment: Most biohazard waste is autoclaved (steam sterilized) or incinerated before landfilling

Hazardous/Chemical Waste

Regulated by the EPA under the “Cradle-to-Grave” principle

  • Manifests: The legal paper trail tracking waste from generation to destruction. The lab is liable until the disposal facility confirms receipt
  • Storage: Waste is collected in “Satellite Areas” (at the bench) and moved to “Central Areas” for shipping. Incompatible chemicals (acids vs. bases) must be physically segregated to prevent dangerous reactions
