Code of Practice

A code of practice is a documented set of recommended practices, rules, and minimum expectations for how specific activities should be carried out and controlled. In industrial and regulated manufacturing environments, it commonly refers to guidance issued by industry bodies, regulators, or companies themselves to standardize safe, compliant, and consistent operations.

Core characteristics

A code of practice typically:

• Addresses a defined topic, process, or risk area, such as machine safety, lockout/tagout, data integrity, or hygienic manufacturing
• Describes practical methods and controls for meeting high-level legal, regulatory, or policy requirements
• Is usually written as guidance or recommended practice, not as law, although it may be referenced by regulations or contracts
• Provides a common reference for training, audits, and operational procedures

In an individual company, a code of practice can be an internal governance document that sets out how employees and contractors must perform certain tasks, often sitting above detailed work instructions and standard operating procedures (SOPs).

Use in industrial and manufacturing environments

Within industrial operations, codes of practice commonly apply to:

• Health, safety, and environment (HSE), such as hazardous materials handling, confined space entry, or emergency response
• Quality and GMP-related activities, such as cleaning, contamination control, or data recording in MES and quality systems
• OT and IT practices, including cybersecurity controls, access management, and configuration management for production systems
• Equipment use and maintenance, such as calibration, lockout/tagout, or guarding standards
• Information management, document control, and record retention for regulated operations

Operationally, codes of practice influence how procedures are written, how MES/ERP workflows are configured, how training is structured, and how internal audits or inspections assess adherence to company and industry expectations.

Relationship to laws, standards, and procedures

A code of practice often sits between high-level requirements and day-to-day instructions:

• Laws and regulations define mandatory requirements at a high level.
• Standards (for example, those published by industry or standards bodies) provide structured frameworks and terminology.
• Codes of practice translate these into topic-specific, practical guidance and expected behaviors.
• SOPs and work instructions provide step-by-step instructions tailored to a site, process, or machine.

In some jurisdictions, complying with an officially recognized code of practice may be considered one accepted way to demonstrate that legal obligations are being addressed, although alternative approaches can exist. Internal company codes of practice may be mandatory under company policy even if they are not legal instruments.

Common confusion

• Code of practice vs. standard: A standard usually defines common technical or management requirements and terminology. A code of practice is more focused on how to apply requirements in practice in a specific area.
• Code of practice vs. SOP: An SOP gives detailed, step-by-step instructions for a particular task or process at a site. A code of practice is higher level, describing principles, required controls, and general methods that multiple SOPs might implement.
• Code of practice vs. code of conduct: A code of conduct focuses on ethical and behavioral expectations for people. A code of practice focuses on how processes and activities should be carried out and controlled.

Context in regulated operations

In regulated manufacturing, codes of practice may influence how companies design quality systems, document control, training programs, and system configurations. They are frequently referenced during internal and external audits as evidence of an organization’s approach to managing specific risks, though they do not themselves constitute proof of compliance.
