Question

1. after thousands of failures, what material finally worked in edisons incandescent light bulb?
2. what were the impacts of the light bulb, especially in the cities? (give at least 3 examples)
3. list 3 safety measures that are a direct result of the triangle shirt waist factory fire.

Explanation:

1. After extensive experimentation, Edison's team discovered that carbonized bamboo could serve as an effective filament in the incandescent light bulb. Bamboo was abundant, and when carbonized, it had the right electrical and thermal properties to glow when electricity passed through it, providing a long - lasting light source.

• Extended Work Hours: Factories and businesses could operate longer into the night, increasing productivity. Workers no longer had to rely solely on daylight for manufacturing, assembly, and other tasks.
• Enhanced Safety and Security: Streets and public areas were better lit, reducing crime rates. People felt safer walking at night, and it was easier to monitor public spaces.
• Cultural and Social Changes: Theaters, restaurants, and other entertainment venues could stay open later. This led to a more vibrant nightlife, with people having more options for socializing and leisure activities after the traditional workday.

• Fire Escapes: Mandated the installation of sturdy, accessible fire escapes on multi - story buildings. These provided an additional means of egress in case of a fire.
• Sprinkler Systems: Many buildings, especially those with a high risk of fire (like factories with flammable materials), were required to install sprinkler systems. These systems could quickly suppress a fire or slow its spread.
• Restricted Door Locking: Factory owners were no longer allowed to lock exit doors from the outside during working hours. This ensured that workers could easily escape in case of an emergency.

Answer:

1. Carbonized bamboo.
2. Extended work hours, enhanced safety and security, cultural and social changes.
3. Fire escapes, sprinkler systems, restricted door locking.
