Spills in areas where pharmaceuticals are produced are not just a problem of cleanliness. They can create a number of significant problems associated with product quality, operator safety, compliance to rules and regulations and protection to the environment. Therefore spillage management is a fundamental component of Good Manufacturing Practices (GMP) within the environment of pharmaceutical production to ensure cleanliness, no contamination and safety of production environments.
This article will cover why spills need to be controlled, types of spills, how to respond to and clean up a spill including preventative measures, the importance of documenting spills and cleaning processes, as well as regulatory requirements for controlling spills and training of personnel on these issues.
In addition to the potential for contamination, there may also be a risk to operator safety with chemical spillage. Some compounds are toxic, flammable or irritating and if spills are left unattended, then this may increase the potential for operators to slip or fall or to experience prolonged exposure to a hazardous material.
Regulatory agencies such as the U.S. Food and Drug Administration and the European Medicines Agency require that manufacturers maintain a clean environment with appropriate conditions and that they establish an effective system for responding to spills. Spillage management also assists in the protection of the environment by preventing the introduction of chemicals into the drainage and ventilation systems.
1. Material spills are usually the result of raw materials, either APIs, excipients or finished product ingredient spills, that if not contained will create contamination hazards due to the risk of cross-contamination with other materials.
2. Chemical and solvent spills will be the result of using cleaning agents, disinfectants or solvent in any of the methods used for manufacturing products. Some chemicals may have volatility or flash point vulnerabilities.
3. Biological or water spills may occur as a result of either water spills or buffer solution or biologically active material spills that may create slip hazards and wet contamination hazards.
Each type of spill will require a different method of response and a different type of PPE.
- Identification of chemical hazards and their toxicity level
- Volume of materials being handled
- Proximity to critical production areas
- Airflow/ventilation patterns
After identifying the potential for spills, companies will then write standard operating procedures (SOPs) for each type of spill.
- Absorbent pads/granules
- Neutralising agents (to neutralise either acid/bases)
- Waste disposal bags
- Personal protective equipment (PPE)
- Dedicated brushes/scoops for clean-up
Spillage response kits should be located strategically near the high risk areas and check regularly to make sure they are available and in working conditions.
Operators need to:
- Notify all personnel in the immediate area
- Wear personal protective equipment (PPE)
- Control the spill using absorbents or barriers
- Prevent any further spread of the material to uncontaminated areas
- If you have spilled any solvent or chemicals, increase ventilation to reduce concentrations of vapors in the air.
1. Use an absorbent starting from the outer edge of the spill inwards.
2. For spilled powder, you may want to use wet rags or a specialized vacuum for powder to prevent aerospacing of the powder particles.
3. For spilled liquid, you would put down an absorbent pad first then sweep up into a container after the pad absorbs most of the liquid.
4. Once the physical part of cleaning up is completed, you would need to disinfect and/or neutralize the area where the spill took place based on the spill material.
5. Decontamination also applies to any tools that were used when cleaning up the spill. Brushes, shovels and other tools used for cleanup should be cleaned and returned to their respective spill kit.
- Place labels on waste containers
- Keep chemical waste separate
- Use approved waste streams
- Document your disposal of waste materials
Personnel must never pour any chemicals down drains unless they are specifically authorized by the environmental rules and regulations.
- Date and time of spill
- What was spilled
- Where it happened
- Who was involved
- Cleanup methods used
- Actions taken to prevent future incidents
Having documentation can provide quality to support investigations and trends. If there was a spill that may affect product quality, an investigation may occur under a deviation or CAPA (Corrective and Preventive Action) processes.
- Identifying hazards
- Basic risk assessment
- Using spillage kits
- Emergency response procedures
- Documentation requirements
Training should happen periodically and when new processes or chemicals are created.
To reinforce your training, the operators should be assessed to show that they understand what they have learned through an evaluation process.
- Validation program for cleaning
- Environmental monitoring
- Compliance With Safety Data Sheets (SDS)
- Control of deviations
- Internal auditing
Integration of overall quality and spill management will allow for both addressing spills and utilizing them as learning experiences to improve processes.
- Written procedures for spillage
- Personnel training records
- The asset maintenance tag (for all spillage kits and associated equipment)
- All records of past spills
- Any CAPA created from a spill incident
Implementing a proper spillage management system shows a manufacturer's dedication to maintaining high levels of product quality in compliance with applicable regulations.
- Secondary containment trays
- Designated transfer stations
- Closed transfer systems (powders and liquids)
- Spill sensors in close proximity to high-risk equipment
- Improved ergonomic design to minimize operator error
By minimizing spills, facilities can protect product quality, maintain safety and improve productivity.
To achieve compliance with regulations, maintain the integrity of our products and ensure the safety of our employees, spillage management in pharmaceutical production areas is crucial to the success of any business. A robust spillage management system includes all components (risk assessment, effective cleanup processes, staff training on procedures, documentation and continuous improvement).
By effectively and systematically managing spills, pharmaceutical manufacturers can protect patients while also creating a culture of quality and safety in the facility.
Why Spillage Management Matters
It is common for pharmaceutical processes to be carried out in areas that have been subjected to limited control over temperature, humidity and use of chemical substances. The handling of these materials is performed in a manner that minimizes the risk of spillage; however, when spillage does occur, it poses a threat to the integrity of the product being produced. If a spillage occurs in a sterile manufacturing environment, there is a possibility that the contamination will affect the integrity of the product, resulting in rejection of the product or recall of the product, which will be very costly.In addition to the potential for contamination, there may also be a risk to operator safety with chemical spillage. Some compounds are toxic, flammable or irritating and if spills are left unattended, then this may increase the potential for operators to slip or fall or to experience prolonged exposure to a hazardous material.
Regulatory agencies such as the U.S. Food and Drug Administration and the European Medicines Agency require that manufacturers maintain a clean environment with appropriate conditions and that they establish an effective system for responding to spills. Spillage management also assists in the protection of the environment by preventing the introduction of chemicals into the drainage and ventilation systems.
Types of Spills in Pharmaceutical Production
In the pharmaceutical industry, spills are typically categorized into three groups:1. Material spills are usually the result of raw materials, either APIs, excipients or finished product ingredient spills, that if not contained will create contamination hazards due to the risk of cross-contamination with other materials.
2. Chemical and solvent spills will be the result of using cleaning agents, disinfectants or solvent in any of the methods used for manufacturing products. Some chemicals may have volatility or flash point vulnerabilities.
3. Biological or water spills may occur as a result of either water spills or buffer solution or biologically active material spills that may create slip hazards and wet contamination hazards.
Each type of spill will require a different method of response and a different type of PPE.
Elements of Spillage Management
Several important components of an effective spillage management plan include:1. Risk Assessment and Planning
Before production starts, a risk assessment is done to find out where there is the highest chance of having a spill (i.e. raw material transfer zones, where product is made or mixed and high-risk process steps like weighing or granulation). The assessment should include:- Identification of chemical hazards and their toxicity level
- Volume of materials being handled
- Proximity to critical production areas
- Airflow/ventilation patterns
After identifying the potential for spills, companies will then write standard operating procedures (SOPs) for each type of spill.
2. Ready Access to Spillage Equipment
Spillage response kits must be easy to find and labelled so they can be located quickly. There are many different items that make up a spillage response kit; they include:- Absorbent pads/granules
- Neutralising agents (to neutralise either acid/bases)
- Waste disposal bags
- Personal protective equipment (PPE)
- Dedicated brushes/scoops for clean-up
Spillage response kits should be located strategically near the high risk areas and check regularly to make sure they are available and in working conditions.
3. Quick Response & Containment
If there is an alleged release of someone’s material or products then what is the first step to be taken? Stopping their company from becoming compromised would be your first priority.Operators need to:
- Notify all personnel in the immediate area
- Wear personal protective equipment (PPE)
- Control the spill using absorbents or barriers
- Prevent any further spread of the material to uncontaminated areas
- If you have spilled any solvent or chemicals, increase ventilation to reduce concentrations of vapors in the air.
4. Cleaning Up & Decontamination
When cleaning up a spill, you should follow cleaning procedures, (see Approved Guidelines for Cleaning Up Chemical Spills):1. Use an absorbent starting from the outer edge of the spill inwards.
2. For spilled powder, you may want to use wet rags or a specialized vacuum for powder to prevent aerospacing of the powder particles.
3. For spilled liquid, you would put down an absorbent pad first then sweep up into a container after the pad absorbs most of the liquid.
4. Once the physical part of cleaning up is completed, you would need to disinfect and/or neutralize the area where the spill took place based on the spill material.
5. Decontamination also applies to any tools that were used when cleaning up the spill. Brushes, shovels and other tools used for cleanup should be cleaned and returned to their respective spill kit.
5. Disposal of Waste Materials
Disposal of spilled materials must meet requirements of both environmental and safety regulations. Therefore, you must perform the following actions:- Place labels on waste containers
- Keep chemical waste separate
- Use approved waste streams
- Document your disposal of waste materials
Personnel must never pour any chemicals down drains unless they are specifically authorized by the environmental rules and regulations.
Documentation and Reporting
All spills should be documented no matter how big. Important elements of the documentation include:- Date and time of spill
- What was spilled
- Where it happened
- Who was involved
- Cleanup methods used
- Actions taken to prevent future incidents
Having documentation can provide quality to support investigations and trends. If there was a spill that may affect product quality, an investigation may occur under a deviation or CAPA (Corrective and Preventive Action) processes.
Training and Competency
To manage spillage effectively, you need trained people. Training programs should cover:- Identifying hazards
- Basic risk assessment
- Using spillage kits
- Emergency response procedures
- Documentation requirements
Training should happen periodically and when new processes or chemicals are created.
To reinforce your training, the operators should be assessed to show that they understand what they have learned through an evaluation process.
Integration with Quality Systems
Spill management must not be done in isolation. It should tie into the larger quality management system (as follows):- Validation program for cleaning
- Environmental monitoring
- Compliance With Safety Data Sheets (SDS)
- Control of deviations
- Internal auditing
Integration of overall quality and spill management will allow for both addressing spills and utilizing them as learning experiences to improve processes.
Regulatory Expectations
Regulators have the expectation that pharmaceutical facilities will keep their areas clean and free from contaminants. During the inspection process, inspectors will look at things such as:- Written procedures for spillage
- Personnel training records
- The asset maintenance tag (for all spillage kits and associated equipment)
- All records of past spills
- Any CAPA created from a spill incident
Implementing a proper spillage management system shows a manufacturer's dedication to maintaining high levels of product quality in compliance with applicable regulations.
Preventive Measures
It is important that you respond effectively but prevention is still our best means of control. Some examples of preventive strategies include:- Secondary containment trays
- Designated transfer stations
- Closed transfer systems (powders and liquids)
- Spill sensors in close proximity to high-risk equipment
- Improved ergonomic design to minimize operator error
By minimizing spills, facilities can protect product quality, maintain safety and improve productivity.
Continuous Improvement
Spillage incidents that occur, regardless of their severity, is an opportunity for organizations to enhance their systems. Conducting a root cause analysis provides the opportunity to improve layout and procedures or to develop additional training. If an organization monitors the trend of spills, adjustments can be made to processes so as to reduce the occurrence of future spills.To achieve compliance with regulations, maintain the integrity of our products and ensure the safety of our employees, spillage management in pharmaceutical production areas is crucial to the success of any business. A robust spillage management system includes all components (risk assessment, effective cleanup processes, staff training on procedures, documentation and continuous improvement).
By effectively and systematically managing spills, pharmaceutical manufacturers can protect patients while also creating a culture of quality and safety in the facility.
