Final answer:
Safety concerns associated with the use of lamps and power supplies include electrical shock, fire hazard, and eye injury. Each of these can be mitigated with proper safety systems and devices, such as insulation, grounding, and protective measures for intense light.
Step-by-step explanation:
When dealing with the use of lamps and power supplies, there are multiple safety concerns to be aware of, namely electrical shock, fire hazard, and eye injury. These concerns fall into 'd) All of the above' category.
Electrical shock occurs when electric current passes through a person, which can range from mild discomfort to fatal injuries. Preventive measures such as proper insulation on wires and grounding systems can help minimize this risk. Fire hazards emerge due to thermal hazards where excessive electric power causes undesired heating effects, such as ignition of nearby flammable materials. This can occur during events like short circuits where electric energy is converted into thermal energy at an unsafely rapid rate. Lastly, eye injury can occur if lamps emit intense light or radiation, potentially harming vision without appropriate protective measures such as shades or diffusers.
