In production and work places, hazardous areas can develop wherever flammable substances and oxygen are present in sufficient quantities to form an explosive atmosphere.
Typical hazardous areas form in chemical factories, refineries, enamelling plants, paint workshops, cleaning equipment, mills and stores for milled products and other combustible dusts, in tank facilities and loading areas for flammable gases, liquids and solids.
- Demonstrate the concepts of explosive materials.
- Demonstrate how a flammable substance and oxygen (air) can form an explosive atmosphere when present in sufficient quantities.
- Simulate how combustible materials mixed with air have a lower and an upper explosive limit and the explosive range lies between these limits.
