Common safety and health topics: 



Hazard Communication Standard 
Hazard

Exposure to  hazardous chemicals and drugs due to untrained or unaware workers:

  • Personnel who are not aware of proper work practices and controls may be exposed to hazardous drugs through the skin, mouth, or by inhalation.
    • The OSHA Technical Manual provides guidance regarding the  adverse health effects from hazardous drugs, ranging from nausea and dizziness, to adverse pregnancy outcomes (OTM vi.2.3).
Example Controls

Implement a written program which meets the requirements of the Hazard Communication Standard to provide for worker training, warning labels, and access to Material Safety Data Sheets (MSDSs).

  • The Hazard Communication Standard, which is generally applicable to hazardous chemicals, is also applicable to certain drugs. 
    • The HCS only applies to pharmaceuticals that the drug manufacturer has determined to be hazardous and that are known to be present in the workplace in such a manner that employees are exposed under normal conditions of use or in a foreseeable emergency [OSHA Interpretation Letter (1994, March 3)].
    • There are exemptions to the standard such as:
      • Drugs that are in solid, final form for direct administration to the patient, e.g., tablets, or pills [1910.1200(b)(6)(vii)]. Note: Many nursing home facilities use only drugs which fall within this exemption.
        • Final form exemption would also apply to tablets or pills that are occasionally crushed, if the pill or tablet is not designed to be dissolved or crushed prior to administration.
      • Consumer products that are subjected to the labeling requirements of the terms as defined in the Consumer Product Safety Act and the Federal Hazardous Substances Act [1910.1200(b)(5)(v)].
  • Chemicals with any of the following characteristics are considered hazardous: carcinogenic, corrosive, toxic or highly toxic, irritating, sensitizing, or target organ effecting. [Hazard Communication Standard Appendix A and chemicals listed in 1910.1000 Table 2].
  • Provide readily available Material Safety Data Sheets (MSDSs) for all hazardous chemicals, including hazardous drugs that meet the Hazard Communication Standard criteria. 
  • All personnel involved in any aspect of the handling of covered hazardous drugs (physicians, nurses, pharmacists, housekeepers, employees involved in receiving, transport or storage) must receive information and training to appraise them of the hazards presented by hazardous drugs in the work area.
  • Employee access to exposure records is required by 1910.1020.

Other Recommended Good Work Practice:

  • Develop, implement and maintain a written hazardous drug safety and health plan to protect those employees who handle or are otherwise exposed to drugs that pose a health hazard to them. 
    • The OSHA Technical Manual Part V, A#1, offers guidance in the development of a drug safety and health plan. 
  • Nursing stations on floors where hazardous drugs will be administered should have spill and emergency skin and eye decontamination kits available and relevant MSDS's for guidance.

  • A list of drugs covered by hazardous drug policies and information on spill and emergency contact procedures should be posted or easily available to employees. 

The Utility, Dietary, and Maintenance, modules also address hazardous chemicals and the Hazard Communication Standard.

Hazardous Drugs During Preparation

Hazard

Exposure to hazardous drugs during preparation due to ineffective engineering/work practice controls and PPE:

Example Controls
  • PPE: OSHA 1910.132 requires the employer to assess potential hazards and then select and ensure the use of appropriate PPE to protect employees from hazardous chemicals, including hazardous drugs as defined by the Hazard Communication Standard.
  • Eye and Face Protection: OSHA 1910.133 requires the use of chemical-barrier face and eye protection  whenever splashes, sprays, or aerosols of HD's may be generated that could result in eye, nose, or mouth contamination. 

Other Recommended Good Work Practice: 

  • Biological Safety Cabinets: Approved Biological Safety Cabinets (BSC) should be used when preparing hazardous medications. (OSHA Technical Manual Part V, Section B, #2). 
  • Class II, type B, or Class III BSCs that vent to the outside are recommended. (Part V, Section B, #3, c).  
  • OSHA does not recommend Horizontal BSCs for the preparation of hazardous drugs, since they increase the likelihood of drug exposure. (Part IV, Section A, #3).
  • The BSC should also contain:
  • Covered needle containers for needle disposal.
  • Covered waste container for excess fluids disposal.
Personal Protective Equipment (PPE) The OSHA Technical Manual, describes the effective use of gloves and gowns when working with Hazardous Drugs (Part V, Section B, #6).
  • The thickness of the gloves used in handling hazardous drugs is more important than the type of material. The best results have been seen with latex gloves.
  • Double gloving is recommended because all gloves are permeable to some extent, and their permeability increases with time.
    • When double gloving, one glove should be placed under the gown cuff and one over. The glove-gown interface should be such that no skin on the arm or wrist is exposed.
    • To limit transfer of contamination from the BSC into the work area, the outer gloves should be removed after each task or batch, and should be placed in "zipper"-closure plastic bags or other sealable containers for disposal.

 

  • Gloves should be changed regularly (hourly) or immediately if they are torn, punctured, or contaminated with a spill.
  • Thicker, longer, latex gloves that cover the gown cuff are recommend with minimal or no powder since the powder may absorb contamination.
  • The worker should wear a protective disposable gown made of lint-free, low-permeability fabric, with a solid front, long sleeves and tight-fitting elastic or knit cuffs.
  • Handwashing: Hands should be washed before gloves are put on, and after they are removed.

Restricted Preparation areas: OSHA and the American Society of Hospital Pharmacists recommend that hazardous drug preparation be performed in a restricted area, with signs restricting the access of unauthorized personnel prominently displayed (Part V, Section B, #1).

  • Restricted Activities: Smoking, drinking, applying cosmetics, or eating where hazardous drugs are prepared, stored, or used, increases the chance of exposure, and should be prohibited (Part V, Section B, #1).

 

 

Handling Practices

Hazard

Exposure to hazardous drugs (HDs) through improper:

Example Controls

When handling hazardous drugs good work practice includes: 

  • Hazardous Drugs should be prepared by pharmacists, not by nurses or physicians without proper PPE and engineering controls. The risk of exposure to hazardous drugs through inhalation or direct skin contact, is present in procedures such as:
    • Transferring hazardous drugs from one container to another, reconstituting or manipulating them.
    • Withdrawal of needles from drug vials.
    • Expulsion of air from a drug-filled syringe.
      • Expelling air from syringes should be done in the biological safety cabinet, not by the health care worker giving the injection. Technical Chapter Part V, Section C, #1.

 

Sharps Handling: OSHA and the American Society of Hospital Pharmacists (ASHP) recommend that all syringes and needles used in the course of preparation be placed in "sharps" containers for disposal without being crushed, clipped or capped. Technical Chapter Part V, Section C, #1, b. 

Priming of tubing for hazardous drugs: The OSHA Technical Manual Part V, Section C, #1, c, recommends that drug administration sets be attached and primed within the BSC prior to addition of the drug. This eliminates the need to prime the set in a less well-controlled environment. It also states that the priming should be done with non-drug containing solution or that a back-flow closed system be used.

Labeling Practices: In addition to standard pharmacy labeling practices, all syringes and IV bags containing hazardous drugs should be labeled with a warning label such as: Special Handling/Disposal Precautions.  Technical Chapter Part V, Section C, #1, a.

 


Hazardous Drugs During Administration

Hazard

Exposure of administering personnel to hazardous drugs during administration including aerosolized drugs.

Example Controls

Good work practice recommends: 
  • Personnel administering Hazardous Drugs wear gowns, latex gloves, and chemical splash goggles or equivalent safety glasses. OSHA's Technical Manual Chapter (Part V, Section C, #2) and the National Study Commission on Cytotoxic Exposure.
  • When administering aerosolized drugs additional precautions may be necessary to protect the employee from exposure such as:
    • Wearing NIOSH-approved respirators.
    • The use of treatment booths with local exhaust ventilation systems, or isolation rooms with separate HEPA filtered ventilation systems.

The American Society of Hospital Pharmacists (ASHP) recommends these guidelines when administering hazardous drugs:

  • Only those trained to administer hazardous drugs should be allowed to perform this function.
  • Disposable gloves and gowns should be worn. The glove and gown cuffs should be worn in a manner that produces a tight fit (e.g., loose glove tucked under gown cuff; tight glove fitted over gown cuff).
  • Intravenous containers designed with venting tubes should not be used.
  • The use of plastic backed absorbent liners under I.V. tubing during administration of hazardous drugs to absorb any leakage and prevent the solution from spilling onto patient skin.
  • Work at waist level, if possible; avoid working above the head or reaching up for connections or ports.
  • Until the reproductive risks associated with handling Hazardous Drugs have been substantiated, staff who are pregnant or breast-feeding should avoid contact with these drugs.

 

 

Hazardous Drugs During Care Giving

Hazard

Exposure to Hazardous Drugs during care giving:

  • When dealing with excreta that may contain high concentrates of hazardous drugs.

Example Controls

Special precautions need to be taken by personnel while caring for the patient who has been taking hazardous drugs.

OSHA requires:

  • If personnel are unable to differentiate between body fluid types, care should be given in accordance with the Bloodborne Pathogens Standard
    • Universal precautions must be observed to prevent contact with blood or other potentially infectious materials.

Other Recommended Good Practices:

  • Personnel (nursing, housekeeping) dealing with excreta, primarily urine, from patients who have received Hazardous Drugs in the last 48 hours, should wear PPE, gloves, and gowns.
  • The American Society of Hospital Pharmacists (ASHP) recommends: 
    • Gloves be discarded after each use and immediately if contaminated. 
    • Gowns should be discarded on leaving the patient-care area and immediately if contaminated.
    • Hands must be washed thoroughly after hazardous drugs are handled. 
    • Disposable linen or protective pads should be used for incontinent or vomiting patients. 
    • Contaminated non-disposable linen or protective pads require pre-washing.

 

 

Disposal of Hazardous Drugs

Hazard

Exposure to Hazardous Drugs during disposal:

Example Controls

Bagging and labeling:

OSHA requires:

Other Recommended Good Practices:

  • Thick, leak-proof plastic bags, colored differently from other hospital trash bags, should be used for routine collection of discarded gloves, gowns and other disposable material, and labeled as Hazardous Drug-related wastes.
    • The Technical Chapter suggests the waste bag should be kept inside a covered waste container clearly labeled "Hazardous Drug WASTE ONLY." At least one such receptacle should be located in every area where the drugs are prepared or administered. Waste should not be moved from one area to another. The bag should be sealed when filled and the covered waste container taped.
  • Hazardous Waste Disposal and Containers: The OSHA Hazardous Drugs Technical Chapter (Part IV), Section A recommends:
    • Labeling needle containers and breakable items of hazardous waste as Hazardous Drug waste only.
    • The use of properly labeled, sealed and covered disposal containers, handled by trained and protected personnel, as required under the Bloodborne Pathogens Standard if such items are contaminated with blood or other potentially infectious materials.
Hazardous drug-related wastes should be disposed of according to EPA, state and local regulations for hazardous waste.

 

 

Hazardous Drugs During Storage

Hazard

Exposure to hazardous drugs during storage.

Example Controls

The OSHA Technical Manual recommends:

  • Storage of Hazardous Drugs: Access to areas where Hazardous Drugs are prepared and stored is limited to authorized personnel only, with signs restricting entry.
  • Storage Area for Hazardous Drugs: Bins or shelves where Hazardous Drugs are stored should be designed to prevent breakage and to limit contamination in the event of leakage with bins with barrier fronts, or other design features that reduce the chance of drug containers falling to the floor.
    • Warning labels should be applied to all HD containers, shelves, and bins, where these containers are stored.
    • The American Society of Hospital Pharmacists (ASHP) recommends hazardous drugs requiring refrigeration be stored separately from non-hazardous drugs in individual bins designed to prevent breakage and contain leakage.

 

Latex Allergy

Some employees, develop latex allergy from exposure to latex in products like latex gloves. This can cause reactions from irritant contact dermatitis, and allergic contact sensitivity to immediate possible life threatening sensitivity.

Hazard

Developing latex allergies from exposure to latex products.

Example Controls

OSHA requires:

  • Bloodborne Pathogen Standard states, The employer shall ensure that appropriate personal protective equipment in the appropriate sizes is readily accessible at the worksite or is issued to employees. Hypoallergenic gloves, glove liners, powderless gloves, or other similar alternatives shall be readily accessible to those employees who are allergic to the gloves normally provided [1910.1030(d)(3)(iii)]. 
    • Please note that hypoallergenic gloves, glove liners, or powderless gloves are not to be assumed to be non-latex or latex free. 

Other Recommended Good Practices:

  • Research indicates the thickness of the gloves used in handling hazardous drugs is more important than the type of material used. Non latex gloves and other latex free products are available. 
  • If latex is used, choose a low protein, powder free glove. (Powder free gloves seem to reduce systemic allergic responses.)

The Laundry, and Bloodborne Pathogens Modules also address Latex Allergy.
