Hazardous Drugs

health concerns

Introduction

OSHA says worker exposure to hazardous drugs is a major health concern for workers in healthcare facilities and the pharmaceutical industry. The preparation, administration, manufacturing, and disposal of hazardous medications may expose hundreds of thousands of workers to potentially significant workplace levels of these chemicals.

Health Effects

Potentially harmful exposure can occur when you handle or work around hazardous drugs. These drugs include antineoplastic cytotoxic medications, anesthetics, anti-viral drugs, hormones, and others.

Hazardous drugs can cause serious acute and chronic health effects such as skin rashes, fertility problems, genetic damage, birth defects, organ toxicity, and possibly leukemia and other cancers.

2012 NIOSH List of Antineoplastic and Other Hazardous Drugs

Scenario

A 41-year-old patient-care assistant working on an oncology floor developed an itchy rash approximately 30 minutes after emptying a commode of urine into a toilet. She denied any direct contact with the urine, wore a protective gown and nitrile gloves, and followed hospital policy for the disposal of materials contaminated with antineoplastic drugs. The rash subsided after 1 to 2 days. Three weeks later, she had a similar reaction approximately 1 hour after performing the same procedure for another patient.

Upon investigation, it was found both hospital patients had recently been treated with vincristine and doxorubicin. The patient-care assistant had no other signs or symptoms and reported no changes in lifestyle and no history of allergies or recent infections. After treatment with diphenhydramine (intramuscular) and oral corticosteroids, her symptoms disappeared.

Although the cause could not be definitely confirmed, both vincristine and doxorubicin have been associated with allergic reactions when given to patients. The aerosolization of the drug present in the urine may have provided enough exposure for symptoms to develop.

Hazardous Drug Exposure

exposure

Exposure occurs during manufacturing and packaging, receiving, preparation and administration, and cleaning and disposal activities. Clinical and non-clinical workers with potential exposure include:

  • pharmacists and pharmacy technicians
  • nurses
  • physician assistants
  • physicians
  • nursing home, home health care, and assistive care staff
  • housekeeping and environmental services staff (custodial, laundry, and waste handling workers)
  • shipping and receiving personnel
  • veterinarians and veterinary technicians and assistants

Hazard Communication Standard

The exposure to these hazardous chemicals and drugs due to untrained or unaware workers can cause problems, such as:

  • Personnel who are not aware of the proper work practices or controls may be exposed to the hazardous drugs through the skin, mouth, or by inhalation.

Employers should implement a written program which meets the requirements of the Hazard Communication Standard (HCS) for employees who are handling or exposed to the chemicals, including drugs that represent a health hazard to employees. The written program must provide for worker training, warning labels, and access to Material Safety Data Sheets (MSDSs).

Hazardous Drug Safety and Health Plan

drug plan

When a Hazardous Drug Safety and Health Plan is developed, it should be readily available and accessible to all employees, including temporary employees, contractors, and trainees.

OSHA says the plan should include each of the following elements and indicate specific measures that the employer is taking to ensure employee protection:

  • Standard operating procedures relevant to safety and health considerations to be followed when health care workers are exposed to hazardous drugs.
  • Criteria the employer uses to determine and implement control measures to reduce employee exposure to hazardous drugs, including engineering controls, the use of personal protective equipment, and hygiene practices.
  • A requirement that ventilation systems and other protective equipment function properly, and specific measures to ensure proper and adequate performance of such equipment.
  • The plan should have a provision for information and training and medical examinations of potentially exposed personnel.
  • The circumstances under which the use of specific hazardous drugs require prior approval from the employer before implementation.
  • Employers should designate a responsible person to implement the Hazardous Drug Safety and Health Plan. This includes assigning a Hazardous Drug Officer (who is an industrial hygienist, nurse, or pharmacist health and safety representative) and, if appropriate, establishment of a Hazardous Drug Committee or a joint Hazardous Drug Committee/Chemical Committee.

Informing Employees

Employees must also be informed of the requirements of the Hazard Communication Standard, including:

  • any operation/procedure in their work area where hazardous drugs are present
  • the location and availability of the written hazard communication program

The HCS only applies to pharmaceuticals the drug manufacturer has determined to be hazardous. It also applies to workplaces where employees are exposed under normal conditions of use or in a foreseeable emergency.

Employer Responsibilities

Departments with employees who handle hazardous drugs on a regular basis must:

  • Ensure employees follow the procedures in the hazardous drug safety and health plan.
  • Develop additional written procedures as appropriate.
  • Ensure all hazardous drugs are labeled properly and safety data sheets are available for all drugs in liquid, powdered, and gaseous form.
  • Develop a plan for cleaning up hazardous drug spills and provide spill kits to all areas where hazardous drugs are administered. Whenever possible, spills of liquid hazardous drugs will be handled by employees in the area of the spill.

Employee Responsibilities

Employees who handle hazardous drugs should:

  • Comply with the procedures outlined in the plan and with department- or site-specific procedures related to handling hazardous drugs.
  • Report any exposures (skin or eye contact or inhalation of an aerosol or dust) to their supervisors.

Hazard Assessment

responsibility

The hazard assessment is conducted to help you identify what tasks have the potential for exposure, which employees may be exposed, and how to control exposure. It will form the foundation of your Hazardous Drug Control Program.

Written Hazard Assessment

Here are some steps to help you conduct your hazard assessment:

  1. Develop an inventory of hazardous drugs stored, transported, or otherwise handled in your facility.
  2. Identify the tasks performed where an employee may be reasonably anticipated to have exposure to a hazardous drug.
  3. Characterize the potential exposure for each task, including exposure by contact, injection, or inhalation.
  4. Determine the preventive methods that will be used for each of the identified tasks and exposures for your work operations and worksites.
  5. Complete a diagram of the physical layout of your work areas where hazardous drugs may be located or used; however, a diagram will not be needed for temporary worksites.

HCS Exemptions

There are some exceptions to the standard, such as:

  • Drugs that are in solid, final form for direct administration to the patient. (e.g., tablets or pills)
  • Chemicals with any of the following characteristics are considered hazardous:
    • carcinogenic
    • corrosive
    • toxic or highly toxic
    • irritating
    • sensitizing
    • target organ effecting
