Question

what chemical,electric, or energy hazard are associated with experiment

Answer 1

Chemical hazards - in laboratory handling various types of chemical is a common practice with so much chemicals around there is great risk involved with it. These risk are as hazards. Various chemical hazards are-

• Contact with chemicals : the nature of chemical varies in laboratory some are acids some are bases. Coming in direct contact with can cause burns bur skin problems.
• Explosive chemicals: some chemicals are so volatile that if kept unchecked can cause explosion in the lab.
• Poisonous chemicals: there are various toxic chemicals , inhaling them by mistake can be lethel.
• Radioactive element: there are some elements which are radioactive in nature. Proper care is needed to handle them.

Electric hazards : for experimentation we need various types of electrical instruments, machines and circuits. The hazard related with this is known as electric or energy hazard.

• Electric shock: the most common risk involved with electric instruments is electric shock. In labs high voltage and current can be used for experiment. There is always risk involved with that.
• Short circuit: with very large number of wires involved a wrong connection can lead to such accident. With so much apparatus involved this can be a common mistake.
• Electric heating: there always heating with the electric instruments. Keeping that in light instruments should be handled with great care as this can cause burns or sometime fire not to mention the damages in instruments.
