This paper attempts to construct a useful laboratory for the chemistry class of a high school in Tanzania.
The overall safety profile of schools would be greatly improved if the chemistry laboratory, preparation room and chemical stores area were properly designed in the first place. Many schools are now in the process of renovating or building new chemistry labs.
A laboratory is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratory services are provided in a variety of settings physicians’ offices, clinics, hospitals, and regional and national referral centers.
School science lab supplies play an important role in the advances and technologies being made in the world. Today, high school science education aims to provide scientific literacy for all as part of a liberal education and to prepare students for further study, work, and citizenship. As the goals of Tanzania educational policy is to provide young scientists, promoting of science subjects and using of the schools’ laboratories can stand as a powerful tool to build up the minds’ sets of our students to scientific universe.

Project Goals and Scope
The primary aim of this project is to address the lack of specialized infrastructure by transforming an existing classroom into a modern, safe, and efficient chemistry laboratory. The initiative seeks to transition from substandard experimental conditions to a professional environment that adheres to safety and technical standards for chemistry education.
- Enhancement of practical chemistry subject mastery for students.
- Improvement of safety standards for students and teachers during experiments.
- Establishment of design requirements for modern laboratory health and safety.
- Acquisition of necessary chemical reagents and laboratory equipment.
- Creation of a conducive environmental setting for academic research and practical work.
Excerpt from the book
Laboratory Design Considerations
1. The laboratory shall be bound by four walls and a roof or ceiling.
2. Each laboratory using hazardous materials, whether chemical, biological, or radioactive, should contain a sink for hand washing.
3. All work surfaces (e.g., bench tops, counters, etc.) should be impervious to the chemicals and materials used in the laboratory.
4. The laboratory shall be designed so that it can be easily cleaned. Bench tops should be of a seamless one-piece design to prevent contamination. Penetrations for electrical, plumbing, and other considerations should be completely and permanently sealed
5. The walls shall be non-porous and painted with durable, impervious finish to facilitate decontamination and cleaning
6. Should have fumes hood: A good rule of thumb is to keep the fume hood location away from heavy student traffic areas and main exits.
