Contact between two moving surfaces, or one moving surface and a stationery one, can lead to the production of electrostatic changes. List the measures that can be taken to reduce the risk of a fire occurring as a result of build up of such charges.
b. Friction is also common source of ignition in industrial workplaces and is again associated with movement. Explain concisely the difference between friction and the electrostatic charges as asource of ignition.
c. List measures that may be taken to reduce the risk of a fire occuring as a result of the build up of heat by friction
