Risk of Injury and Infection from Broken Glass Ampules



Hazard [Health Devices Jan-Feb 1994;23(1-2):56]

Problem

A member hospital reported that, in three separate incidents, employees were cut on the fingers when opening glass ampules of clinical laboratory human-based quality control material.

Discussion

Glass ampules, which can contain different types of solutions, some of which are biohazardous, pose the risk of cuts to the hand and scattering of glass fragments when snapped open at the neck, thus exposing sharp glass on the edges of the lid and base. Also, particulate material can spray when the ampules are opened, creating a biohazard risk.

Recommendations

  1. When opening glass ampules, use a device such as an ampule opener to minimize the risk of injury, especially when the ampules contain biohazardous materials. (Note, however, that these devices may not protect users from glass fragments and/or particulate matter.)
  2. Follow universal precautions when handling biohazardous materials. These precautions include wearing gloves (special puncture-resistant gloves are available to minimize the risk of punctures and/or cuts), facial protection (e.g., shields), gowns or laboratory coats, and plastic aprons, as outlined by the National Committee for Clinical Laboratory Standards (NCCLS).(1) Wrap materials such as gauze and/or paper towels around the ampule to reduce exposure to shattered glass and/or sprayed particulate matter.
  3. Dispose of opened glass ampules in sharps containers. (See our Evaluation "Sharps Disposal Containers" in Health Devices 22[8-9], August-September 1993.)
