Final answer:
To prevent broken glass from contaminating food or food-contact surfaces, all lights should have a protective cover. Protective eyewear is also important to protect the eyes from ultraviolet radiation. LED and CFL lamps are energy-efficient alternatives to incandescent lamps.
Step-by-step explanation:
In order to prevent broken glass from contaminating food or food-contact surfaces, all lights should have a protective cover. These covers can be made of materials such as polycarbonate, which is commonly used for household cookware and sealed beam car headlamps.
Protective eyewear is also important when working with lights, as it helps to protect the eyes from ultraviolet radiation. Full coverage eye protection is recommended, and most plastic lenses, such as polycarbonate, offer more protection than glass lenses.
Moreover, the use of light-emitting diode (LED) lamps and compact fluorescent lamps (CFL) as more energy-efficient alternatives to incandescent lamps is being phased in many countries, including the United States, since 2012.
