How to Make LPG Safer in the Laboratory
The following must be observed in the laboratory:
1. The LPG cylinders should be kept outside the laboratory in a ventilated room.
2. A typical store room for cylinders may be constructed for eight to sixteen cylinders depending on the requirement of the lab. Do not connect all the cylinders to the feeder pipes simultaneously; two to four cylinders are sufficient.
3. Regulate the pressure of the gas to the optimum level.
4. In the laboratory ensure that all the burners connected to gas supply are in working condition and the tubing used for connection is IS1 approved.
Never use ordinary rubber tubing. Inspect the rubber tubing for its condition and replace if needed once in a year at least.
5. Ensure that highly volatile liquids are never heated directly on the flame.
6. Give clear instructions to the students to close the burner knobs after the use. Also ensure that the cylinder knobs are closed are the laboratory work is over.
7. Use spark freeswitches.
