Hazardous Materials, Sharps and Biohazard Waste
- Identify safe handling, storage, and emergency response protocols for hazardous chemicals, antineoplastic medications, and radiation sources.
- Apply safe work practices for sharp-device usage, disposal container management, and immediate post-exposure procedures following a needlestick injury.
- Distinguish regulated biohazard waste from general waste and execute appropriate containment, specimen transport, and soiled linen procedures within the practical nurse scope.
Hazardous Chemicals, Hazardous Drugs, and Radiation Safety
In healthcare environments, practical nurses frequently encounter dangerous substances ranging from concentrated surface disinfectants to hazardous medications. Safety Data Sheets serve as the foundation of chemical safety. These documents provide essential information regarding chemical hazards, safe handling precautions, storage requirements, and emergency spill responses. Facilities are required to keep Safety Data Sheets readily accessible to healthcare personnel during every work shift, whether stored electronically on a workplace network or available in print. The practical nurse must consult the Safety Data Sheet before handling any unfamiliar hazardous substance and don the personal protective equipment specified by the document prior to contact. When chemicals are transferred into secondary containers, the practical nurse ensures they are properly labeled with a product identifier and hazard information consistent with facility hazard-communication procedures, reporting any missing, faded, or damaged hazard labels directly to the charge nurse.
Specific classes of therapeutic agents present severe occupational risks and demand specialized handling barriers. Wear chemotherapy-tested gloves when handling antineoplastic medications; wear a protective gown when the task presents an exposure risk or facility policy requires one. Even when administering intact oral antineoplastic tablets or capsules, practical nurses must wear chemotherapy-tested gloves. Do not crush, split, or open oral hazardous-drug doses at the bedside; refer any necessary manipulation to authorized, trained personnel using required engineering controls and protective equipment. Because hazardous drugs remain active in client excretion pathways, practical nurses must handle body fluids and soiled linens from clients receiving hazardous antineoplastic drugs using appropriate personal protective equipment for at least 48 hours, or longer if required by the drug or facility policy. Handle linens contaminated with hazardous-drug excreta using designated laundry precautions, and dispose of disposable items and body fluids according to facility hazardous-drug procedures.
Caring for clients receiving internal radiation therapy requires strict adherence to physical protection principles. Practical nurses minimize personal exposure by applying three standard radiation safety precautions: minimizing exposure time near the source, maximizing physical distance from the source, and using shielding appropriate to the radiation source. When caring for clients with internal radiation sources, staff members must wear an assigned personal dosimeter whenever required by the facility's radiation safety program to monitor cumulative exposure. Practical nurses who are pregnant should follow facility procedures for declaring pregnancy and consult radiation safety personnel regarding work assignments that involve clients with internal radiation sources.
Common mistakes
- Discarding routine adhesive bandages with tiny spots of dried blood into expensive regulated biohazard containers when facility policy directs them to regular trash.
- Documenting in the client's medical record that an incident report was completed following a chemical spill or needlestick exposure.
- Squeezing a needlestick puncture wound or applying harsh cleansers such as bleach instead of washing the site immediately with soap and water.
- Shaking or rinsing soiled bed linens inside a client's room, which aerosolizes pathogens into the immediate environment.
Key points
- Safety Data Sheets detail hazards, handling rules, and spill protocols, and they must be accessible to staff on every shift.
- Handling oral antineoplastic drugs requires chemotherapy-tested gloves, and client body fluids require hazardous-drug precautions for at least 48 hours.
- Radiation protection relies on minimizing time, maximizing distance, and utilizing shielding, with personal dosimeters worn when required.
- In any chemical spill, clear and isolate the area first, notify the registered nurse and safety personnel, and allow only trained staff to clean large or cytotoxic spills.
- Never recap needles using two hands, activate needle safety devices immediately, and replace sharps containers once they reach the marked fill line.
- Treat needlestick injuries immediately by washing with soap and water, report promptly to the registered nurse or supervisor, and seek occupational health evaluation.
- Regulated biohazard waste involves pourable, squeezable, or flaking blood/OPIM, requiring labeled red leak-proof containment, while soiled linens must never be shaken or rinsed in client care areas.
