Managing the risks from handling cytotoxic medicines

Guidance on how to find and control hazards and risks when handling cytotoxic medicines in the workplace.

The risk management process

A hazard is something that can cause harm. A risk is the chance of a hazard causing harm. Harm includes injury, illness and death. Like other industries, handling cytotoxic medicines has a wide range of hazards and risks. The risks must be controlled by duty holders, so far as is reasonably practicable.

A safe and healthy workplace requires an organised approach to finding and controlling hazards and risks. This approach is known as the risk management process.

The risk management process follows a series of steps:

  1. Identify hazards.
  2. Assess the risks those hazards create.
  3. Control risks. Do this by eliminating the risk. If it's not reasonably practicable to eliminate risks, reduce them as far as is reasonably practicable.
  4. Review and revise risk control methods.

The importance of consultation

A successful risk management process involves consultation between employers and employees, as well as any Health and Safety Representatives (HSRs). Consultation is a requirement under Part 4 of the Occupational Health and Safety Act 2004 (OHS Act). 

Consultation draws on the experience and knowledge of employees and HSRs. It must, so far as is reasonably practicable, happen at each stage of the risk management process. For example:

  • When identifying hazards and risks arising from cytotoxic medicines. This includes:
    • before changing systems of work that are likely to change the risk of managing cytotoxic medicines
    • when a registered medical practitioner has identified adverse health effects through health monitoring 
    • when following up any adverse incident involving managing cytotoxic medicines 
    • where risk control measures do not adequately control risks
    • on request from a health and safety representative.
  • When determining which control strategies to apply to eliminate or reduce risks from the handling of cytotoxic medicines.
  • When reviewing the effectiveness of control measures.
  • After an incident occurs that is notifiable under Part 5 of the OHS Act (notifiable incident) and involves cytotoxic medicines.

Consultation should take place as early as possible:

  • when planning to introduce new cytotoxic medicines into the workplace
  • if a Safety Data Sheet (SDS) is updated. 

Consulting employees and HSRs at each step of the risk management process encourages everyone to:

  • identify hazards and risks associated with the storage and handling of cytotoxic medicines
  • put in place effective control measures.

Ways to consult with employees include:

  • direct discussion
  • staff meetings
  • health and safety committee meetings
  • health and safety inspections
  • special working parties 
  • any combination of the above.

You must make relevant and accurate safety information available to employees and their HSRs. This may include:

  • the SDS
  • any other information relevant to the storage and handling of cytotoxic medicines and their waste.

HSRs need to be given time to:

  • meet with employees
  • meaningfully consider options 
  • propose ideas to employers.

It is important to consider the needs of employees and HSRs from non-English-speaking backgrounds. As an employer, you have a duty to provide information, instruction and training to employees in a language they can understand. This is so they can do their work safely and without risks to their health. 

The steps of the risk management process

Hierarchy of control for cytotoxic medicines

This is an example of a hierarchy of control that may help employers control risks from cytotoxic medicines in the workplace. You may not be able to eliminate the use of cytotoxic medicines, but redesigning processes may eliminate risk for some employees.

Level 1: Eliminate the risk

Control
Examples
Eliminate the risk – most effective

It is rarely possible to eliminate the need for cytotoxic medicines for treatment. 

A first-level risk control measure may be to identify an alternative supply for cytotoxic drugs, including:

  • Buying cytotoxic medicines in ready-to-administer (RTA) preparations. This eliminates the risk for those who prepare medicines (like pharmacy employees) 
  • Establishing supply arrangements with a company or healthcare institution that specialises in preparing cytotoxic medicines.

Level 2: Reduce the risk 

Control
Examples

Substitution

Substitution involves using a less hazardous substance or a substance in a less hazardous form.

  • It is rarely possible to provide alternative treatments where cytotoxic drugs are required.

Isolation

Isolation involves separating people from the substance by distance or barriers to prevent or reduce exposure.

Using the following control measures together:

  • adopting closed-system transfer devices
  • isolating employees from cytotoxic medicines in a fit-for-purpose secure cleanroom, with a suitable drug preparation cabinet such as a CDSC for preparation
  • placing dispensed medication in impermeable packaging for delivery to administration areas
  • administration of intravenous preparation using the back priming technique.

Engineering controls

Engineering controls are physical controls or processes that:

  • reduce the generation of substances
  • suppress or contain substances
  • limit the area of contamination in the event of spills and leaks.

Prepare cytotoxic medicines in a purpose-designed clean room that comprises:

  • A primary barrier to provide drug containment and aseptic handling. For example, a CDSC with high efficiency particulate air (HEPA) filters.
  • A secondary barrier to prevent contamination of the outside environment. This should supply HEPA-filtered air to the cleanroom that is at a lower pressure than air outside the cleanroom.

Use:

  • wide-bore needles to transfer, reconstitute and draw up cytotoxic medicines
  • CSTDs  
  • needle-less injection sets for drug administration.

Incorporate secure storage facilities.

Level 3: Use administrative controls

Administrative controls

There may still be a risk even after higher levels of control have been used. Administrative controls such as systems of work and work procedures may further reduce the risk. 

Administrative controls are ways of working that reduce employee exposure to cytotoxic medicines and related waste.

For administrative controls to be effective, employees need to fully cooperate. It is important to consult as controls are developed. Adequate supervision and training are crucial for these new work practices.

  • Allocate responsibilities for health and safety. This may be an area manager or delegated to an employee.
  • Reallocate jobs for specific risk groups (such as pregnant employees) based on risk assessment.
  • Keep containers of cytotoxic medicines secure when not in use.
  • Use cytotoxic signs and labels to clearly identify all cytotoxic medicines and waste.
  • Store cytotoxic waste in specific, clearly identified areas, separate from other waste.
  • Develop and use standard work procedures for all activities.
  • Set cleaning schedules and clean work areas regularly.
  • Develop emergency procedures to deal with spills.
  • Ban eating and drinking in work areas.
  • Ban wearing of jewelry and cosmetics in preparation areas.

Level 4: Use PPE

Personal Protective Equipment

PPE is something worn that provides a barrier between the person and the hazard. It is one of the controls required for employees who handle cytotoxic medicines or waste. 

Employers must ensure that all employees know how to fit and use PPE. Look for guidance from:

  • suppliers of cytotoxic medicines
  • suppliers of PPE
  • published technical standards.

Make sure PPE is:

  • properly selected for the individual and task
  • readily available
  • clean and functional
  • correctly used when needed
  • maintained by appropriately trained employees, in keeping with relevant standards.

See: Personal protective equipment for handling cytotoxic medicines for more information.

PPE needs to meet approved standards for use with cytotoxic medicines. For example, American Society for Testing and Materials International (ASTM) standards.

PPE can include:

  • coveralls
  • gowns
  • head coverings
  • closed footwear
  • overshoes
  • nitrile gloves
  • safety glasses
  • respiratory protective equipment (for example, P2/N95).

Step 4: Review and revise risk controls

Employers must review risk controls to make sure they are working as planned:

  • Before changing any system of work in a way that could alter the risk associated with the handling of cytotoxic medicine. This could be, for example, when introducing a new cytotoxic medicine.
  • If a registered medical practitioner advises that health monitoring has identified adverse health effects.
  • If the risk control measures do not adequately control the risks. For example, employees are unable to identify patients who require cytotoxic precautions.
  • After a notifiable incident involving cytotoxic medicines at the workplace.
  • After receiving a request for review from an HSR. An HSR can make a request if they believe, on reasonable grounds, that:
    • any of the circumstances listed above exist
    • the employer has failed to properly review the risk controls
    • in conducting a review of, or revising, the risk controls, the employer has failed to consider any of the circumstances listed above. For example, the employer has failed to consider a change to a work system that may lead to an increase in risks.

It is also good practice to review risk controls periodically.

Employers can review the effectiveness of risk controls by, for example:

  • conducting regular safety inspections
  • asking for feedback from employees who use the risk controls.

Review control measures

Action
Example
Look at how control measures are working in practice, to ensure they perform as intended and continue to provide adequate control.

Reviewing control measures may include:

  • frequent inspections
  • visual checks to ensure controls are being properly applied in the workplace
  • testing equipment
  • preventative maintenance
  • remedial work
  • consulting with employees and HSRs
  • monitoring where relevant standards exist; for example, using commercially available wipe-testing kits to check surfaces for cytotoxic medicines.
