Standards for Designing a Standard Laboratory

Requirements for Lighting

Lighting is an essential factor in any working environment, especially in places that require a high degree of accuracy. In these environments, light control needs to be more strictly enforced.

According to laboratory design standards, a room can be illuminated by natural or artificial light. Good lighting will support employees in performing tasks in detail, safely and efficiently, thereby reducing unnecessary waste. At the same time, the lighting system design needs to ensure that it does not cause glare or be too dim.

Temperature Requirements

Each laboratory in different industries will have its own specific temperature requirements. Therefore, the temperature needs to be designed to suit the function and purpose of each room. To ensure that the design meets the standard and is not affected by external factors, heat-generating equipment should be placed far away or separated from the workspace.

Ventilation System Requirements

The ventilation system is an essential element in clean rooms and laboratories. This system needs to be installed in accordance with the requirements of each laboratory and must comply with laboratory design standards to ensure an optimal working environment.

Laboratories often use many chemicals, which can produce unpleasant odors, smoke, or toxins. Therefore, it is necessary to establish a local ventilation system in the work areas. Airflow velocity is also an important factor that needs to be monitored regularly to ensure that toxic gases and potential pollutants do not spread to the surrounding environment.

Noise Requirements

When designing laboratories, the selection of machinery and equipment needs to be carefully carried out, including the calculation of noise levels. Measures to reduce or eliminate noise need to be implemented to avoid excessively high noise levels, ensuring that it does not affect work efficiency in the laboratory.

Ergonomic Factors

Machinery and equipment in the laboratory need to be designed and arranged to suit the purpose of the work as well as the operations performed. In particular, it is necessary to limit risks and errors that can affect the safety of workers and product quality.

Layout for working with potentially airborne pathogens

Laboratory design standards must be applied to all laboratories involving biological agents. For microorganisms that are potentially airborne and pose a risk to personal safety and the environment, they must be designed in appropriate locations. In particular, stricter preventive measures are required for microorganisms in risk group III and above.

Laboratory doors

According to laboratory design standards, laboratory entrances and exits must be clearly marked and labeled. In particular, for laboratories containing hazardous biological agents, flammable or explosive substances, or radiation, there must be warning signs indicating the level of danger according to international regulations and the unit’s regulations.

Laboratory safety

As required by laboratory design, all laboratory doors must be lockable and easy to open and close to ensure quick evacuation in emergencies. An internal lock should be provided to restrict entry and contact when conducting experiments with highly hazardous samples. Only authorized personnel who are familiar with the regulations are allowed to enter the laboratory. At the same time, it is necessary to always be prepared for risks related to data theft, equipment theft, or the falsification of biological agents, samples, and chemicals.

Laboratory rules must be strictly adhered to

Before entering the lab, students must ensure that they have a thorough understanding of the general regulations to guarantee safety, as safety is always the top priority.

  • Students are only permitted to conduct experiments under the supervision of a teacher within the lab.
  • It is essential to carefully read the instructions and think critically before starting any experiment.
  • The location of all safety equipment in the lab must always be known.
  • Adherence to the protective clothing regulations is mandatory, including wearing a lab coat, safety goggles, and tying hair back neatly.
  • Lab benches must be cleaned before starting any experiment.
  • Under no circumstances should lab chemicals be tasted, and eating or drinking is strictly prohibited in the lab.
  • Directly looking into test tubes containing chemicals is forbidden.
  • In case of any accidents, such as spilling chemicals, the teacher or lab manager must be informed immediately.
  • After completing the work, hands and face must be washed, and experimental equipment must be cleaned according to the regulations.
  • Any skin contact with chemicals should be rinsed immediately, and if chemicals get into the eyes, they should be flushed with water immediately.
  • Laboratory waste must be disposed of in the designated area according to the instructions.
  • If anything is unclear, do not hesitate to ask for clarification.
