Preventive Measures To Be Taken By AC Coach

Ensure provision of two numbers of DCP type fire extinguishers in A.C. coaches.
Ensure that no protection (MCB/FUSE etc.) is by-passed.
Proper rating of MCBs / fuses shall be used.
Look for any overheating sign after putting ON all electrical loads.
Check the electrical connections, switches, fuses with the help of Infrared temperature gun to detect any overheating.
In the absence of infrared cameras, carry out at least close visual monitoring of all bolted or crimped joints.
Look for tell-tale signs of overheating, such as softened, distorted or charred cable insulation or terminal boards.
Loose or temporary connection, hanging wires/ exposed joints etc. should not be allowed.
Check condition of PVC bushes/ glands provided in junction-boxes.
Replace worn-out bushes/ glands during schedules.
Check condition of insulation especially in junction-boxes. Don’t permit damaged/ broken/ cracked insulation.
Rubbing of cables shall not be permitted.
Check physical condition of wire/ cables for external damage and overheating marks, discoloration of lugs due to excessive flow of current/ overheating.
If smoke/fire observed anywhere in the coach then switch ‘OFF’ power supply immediately.
The locking and securing arrangement for the doors and covers of electrical control/power cubicle and terminal boards should be ensured to prevent unauthorized access to the live parts of electrical equipment.
