Biohazard Disposal & Exposure Control Plans
Key Takeaways
- OSHA requires sharps containers to be puncture-resistant, leakproof, closable, and labeled with the biohazard symbol, and to be replaced when they are three-quarters (3/4) full.
- Used needles must never be recapped by hand; if recapping is unavoidable, a one-handed scoop technique or a mechanical recapping device must be used.
- The OSHA Bloodborne Pathogens Standard requires every employer with occupational exposure risk to maintain a written Exposure Control Plan, reviewed and updated at least annually.
- After a needlestick or sharps injury, the exposed worker must immediately wash the site with soap and water, then report the exposure to a supervisor or occupational health right away.
- Post-exposure prophylaxis (PEP) decisions are time-sensitive and may need to be made within hours of exposure, so medical evaluation must not be delayed.
Sharps Containers and Safe Disposal
Sharps — needles, lancets, scalpel blades, and any other item that can puncture skin — are the single greatest bloodborne-pathogen exposure risk a CPCT/A faces, so OSHA regulates exactly how they must be contained.
A compliant sharps container must be:
- Puncture-resistant, with leakproof sides and a leakproof bottom
- Closable and kept upright during use
- Labeled with the universal biohazard symbol or color-coded (typically red)
- Located as close as possible to the point of use, so a used sharp never has to be carried across a room
The 3/4-full rule: a sharps container must be replaced — not forced closed or shoved down to make more room — once it reaches three-quarters full. Overfilling raises the risk of a needlestick during disposal and can cause the container to leak or fail to close properly.
Never recap a used needle by hand. Recapping, bending, or breaking needles by hand is prohibited because it is a leading cause of needlestick injuries. If a specific procedure absolutely requires recapping, the CPCT/A must use a one-handed scoop technique or a mechanical recapping device — never bring the second hand near the exposed needle tip. Wherever possible, facilities use safety-engineered sharps devices, such as needles with a retractable or shielding mechanism, as an engineering control that reduces the chance of an accidental stick even further.
Biohazard Waste and Regulated Medical Waste
Items saturated or dripping with blood or other potentially infectious material (OPIM) — soaked dressings, cultures, discarded sharps — are regulated medical waste and must be segregated from ordinary trash. OPIM includes body fluids beyond blood itself, such as semen, vaginal secretions, cerebrospinal fluid, synovial fluid, amniotic fluid, and any body fluid that is visibly contaminated with blood; unfixed human tissue and organs are also OPIM.
- Regulated medical waste is placed in red biohazard bags (or red/labeled rigid containers for sharps) marked with the universal biohazard symbol.
- Biohazard bags must be leak-resistant and closed securely before removal from the patient-care area.
- Regulated medical waste is picked up and disposed of through a licensed medical-waste hauler, not regular municipal trash.
- Non-contaminated items — an empty specimen cup, an unused glove, ordinary paper waste — do not belong in a biohazard bag; overusing red-bag waste increases disposal cost without adding any safety benefit.
Correct segregation protects housekeeping staff, waste haulers, and the public from unintended exposure to bloodborne pathogens.
OSHA Exposure Control Plan
Any employer whose staff have reasonably anticipated occupational exposure to blood or OPIM must maintain a written Exposure Control Plan under OSHA's Bloodborne Pathogens Standard (29 CFR 1910.1030). The plan must include:
| Element | What it covers |
|---|---|
| Exposure determination | Job classifications and tasks with occupational exposure risk |
| Methods of compliance | Standard precautions, engineering controls (sharps-safety devices, sharps containers), work-practice controls, and required PPE |
| Hepatitis B vaccination | Offered free of charge to at-risk employees, generally within 10 working days of initial assignment |
| Post-exposure evaluation and follow-up | The procedure a facility follows any time an exposure incident occurs |
| Recordkeeping and annual review | The plan is reviewed and updated at least annually to reflect changes in technology and procedures |
Employers must also provide bloodborne pathogens training at the time of initial assignment and at least annually thereafter, at no cost to the employee and during working hours. An exposure incident is formally defined as specific eye, mouth, other mucous-membrane, non-intact-skin, or parenteral (needlestick or cut) contact with blood or OPIM that occurs while performing job duties. Every CPCT/A must know their facility's Exposure Control Plan and where to find it, because it dictates exactly what happens in the minutes after an exposure.
Post-Exposure Steps After a Needlestick or Sharps Injury
Timing matters after an exposure — some treatment decisions must be made within hours. The sequence:
- Wash the site immediately with soap and water; flush exposed mucous membranes or irrigate the eyes with clean water or saline. Do not squeeze the wound or apply bleach or other caustic agents to it.
- Report the exposure immediately to a supervisor or the facility's occupational health department — do not wait until the end of the shift.
- The source patient is evaluated, with consent where required, for HBV, HCV, and HIV status to guide treatment decisions.
- The exposed worker receives a medical evaluation, and post-exposure prophylaxis (PEP) is started as soon as possible if indicated — this decision may need to be made within hours of exposure, so evaluation must not be delayed.
- The incident is documented on the OSHA 300 Log and/or Sharps Injury Log, and the exposed worker completes any required follow-up testing and counseling.
Following this sequence exactly, without skipping or reordering steps, is what the exam expects — and what protects the CPCT/A after a real exposure. Notice that washing the site comes before reporting, and reporting comes before any decision about treatment: a CPCT/A is never expected to diagnose or decide on PEP independently, only to act immediately on first aid and get the exposure into the facility's evaluation process without delay.
