Laboratory fire hazard classification
Classifies a laboratory unit by the quantities of flammable liquids in it relative to its floor area.
The classification determines the laboratory unit's separation, ventilation and protection requirements, and the maximum quantities allowed in it.
Demonstration scenario
Quality control laboratory, 85 m², storey 2

- A laboratory unit is not the same thing as a control area; the definitions differ and the two must not be mixed.
- It has not yet been settled whether, and in what context, SI 1530 applies alongside NFPA 45.

ת"י 1530
It needs checking whether the Israeli standard applies, and in which edition, before it is mixed with NFPA 45.

Until the source is obtained, the tool shows the interface and the calculation steps, and presents no regulatory value.
