Spark on the presence of flammable liquids may lead explosion, hence flammable liquid containers should be well stored/ handled to avoid explosion. list 5 sources of spark in laboratory
1. Electrical equipment: Sparks can be produced by malfunctioning or improperly grounded electrical equipment such as exposed wires, faulty outlets, or electrical arcs.
2. Static electricity: When flammable liquids are being transferred or poured, static electricity can build up and cause a spark. This can occur through friction, such as when liquids are poured quickly or in a stream.
3. Welding or cutting tools: The use of welding or cutting tools in the laboratory can produce sparks, which can ignite flammable liquids if they come into contact with them.
4. Open flames: Open flames, such as Bunsen burners or gas torches, can produce sparks and ignite flammable liquids if they are not properly controlled or positioned away from the liquids.
5. Friction or impact: Sparks can also be produced by friction or impact, such as when metal objects collide or are struck against another surface. This can occur during handling, storage, or transportation of equipment or materials.
