• Corrosion-resistant materials in areas exposed to moisture or chemicals.
• Easy-to-clean surfaces that support effective housekeeping.
• Secure storage for laboratory instruments, glassware, and supplies.

Furniture selection should be based on the laboratory’s specific applications rather than appearance alone. Appropriate laboratory furniture helps improve usability, simplify maintenance, and support long-term performance.

4. Emergency Safety Equipment and Accessibility

Every laboratory should have suitable emergency equipment based on its hazards and activities. Safety equipment must be accessible, clearly identified, and maintained in working condition.

Depending on the laboratory’s risk assessment, essential provisions may include:

• Emergency eyewash stations and safety showers.
• Suitable fire extinguishers and fire detection systems.
• First-aid supplies and emergency communication arrangements.
• Chemical spill response kits.
• Clearly marked emergency exits and evacuation routes.
• Appropriate emergency shut-off controls for relevant utilities.

The location of emergency equipment should be considered during the initial design stage. Routes to emergency facilities must remain clear, and personnel should receive appropriate training in their use.

5. Safe Chemical and Hazardous Material Storage

Incorrect storage of chemicals and hazardous materials can increase the risk of fire, spills, exposure, and dangerous reactions. A modern laboratory should provide storage solutions that reflect the materials being handled.

Effective storage planning includes:

• Segregating incompatible chemicals.
• Providing suitable chemical storage cabinets.
• Using appropriate secondary containment where necessary.
• Ensuring hazardous materials are clearly labelled.
• Maintaining suitable storage conditions for temperature-sensitive materials.
• Separating hazardous waste from general waste.

Storage requirements vary according to chemical properties, quantities, and applicable regulations. Proper planning helps reduce risks and keeps laboratory work areas organized.

6. Electrical Safety and Laboratory Utilities

Modern laboratories depend on electrical systems, water supply, gases, compressed air, vacuum lines, and other specialized utilities. These systems must be coordinated carefully with the laboratory layout and equipment requirements.

Key design considerations include:

• Adequate electrical capacity for laboratory instruments.
• Properly designed electrical protection and earthing.
• Suitable placement of sockets and utility outlets.
• Safe routing and identification of service lines.
• Accessible isolation valves and emergency shut-offs.
• Appropriate coordination of utility connections with laboratory furniture and equipment.

Utility planning should involve qualified professionals and account for equipment specifications, maintenance access, and future expansion requirements.

7. Cleanroom and Contamination Control Measures

Laboratories involved in pharmaceutical manufacturing, biotechnology, medical research, and other controlled activities may require specialized contamination control measures.

Depending on the application, these can include:

• Controlled room layouts and personnel movement.
• Appropriate cleanroom partitions and finishes.
• Air filtration and pressure control systems.
• Suitable gowning and material transfer arrangements.
• Easy-to-clean surfaces and carefully detailed joints.
• Defined procedures for cleaning and contamination prevention.

Cleanroom classifications, air-change requirements, filtration, and pressure differentials should be established according to the process, risk assessment, and relevant standards. These features are especially important in facilities where product quality and sample integrity depend on environmental control.

8. Biological Safety and Containment Provisions

Laboratories handling microorganisms, biological specimens, or potentially infectious materials require safety measures appropriate to the biological risks involved.

Depending on the work performed, these may include:

• Suitable biological safety cabinets.
• Controlled access to designated laboratory areas.
• Appropriate handwashing and decontamination facilities.
• Safe handling and disposal arrangements for biological waste.
• Suitable surfaces and finishes for cleaning and disinfection.
