A recent article on CBSChicago.com highlights an alarming concern regarding the increased risk of cancer among firefighters. The piece focuses on a groundbreaking new study that has uncovered a striking connection between firefighting duties and the likelihood of developing cancer. This comprehensive research involved nearly 15,000 firefighters, and the findings could potentially trigger significant shifts in standard firefighting practices.
The study, which was just released, examined data from around 30,000 firefighters across three major departments—Chicago, San Francisco, and Philadelphia—over nearly six decades. According to Tom Ryan, president of the Chicago Firefighters Union Local 2, "Our cancer rates are significantly higher compared to the general population." The statistics are staggering: Chicago firefighters are two-and-a-half times more prone to contracting mesothelioma due to asbestos exposure. Additionally, they face a heightened risk of digestive and respiratory cancers, as well as earlier-onset kidney, bladder, and prostate cancers—often occurring before the typical retirement age of 65. These risks stem from harmful chemicals released during the burning of contemporary materials, which can be inhaled or absorbed through the skin, even when not directly exposed to flames.
In response to these findings, a complementary study has proposed practical measures to mitigate these risks. It suggests leaving firefighting gear outside the vehicle post-firefighting and storing it in a dedicated, well-ventilated storage area within the firehouse. Furthermore, firefighters are encouraged to take immediate showers upon returning to the station.
This initial research has already identified more than 30 types of cancer linked to firefighting activities. While the full implications are still being analyzed, a second phase of the study is expected later this year. This follow-up will delve deeper into how specific chemical exposures might contribute to particular types of cancer, offering valuable insights for future safety protocols.
As Dan pointed out, these revelations underscore the urgent need for improved protective measures and ongoing research to safeguard the health of those who put their lives on the line every day.
Thanks, Dan!
Shredder Blades For Plastic
Plastic shredding is a technology for processing and recycling waste plastics. It uses a Shredder to shred large or whole plastic items into small pieces or particles for subsequent processing and reuse. This technology plays an important role in the field of modern waste management and resource reuse.
1. Working principle
Shredding process: The plastic shredder shears and tears the plastic through rotating blades or knife rollers, tearing large pieces of plastic into smaller pieces or particles.
Graded shredding: In some cases, plastics need to be shredded at multiple levels. Primary shredding breaks them down into larger pieces, and secondary shredding further refines them to meet different recycling and processing needs.
2. Application areas
Waste plastic products: Shredders are widely used to process various waste plastic products, such as plastic bottles, plastic bags, plastic packaging, pipes, home appliance housings, etc.
Industrial waste: Plastic waste generated during industrial production, such as scraps, defective products, packaging materials, etc., can be recycled after being processed by shredders.
Agricultural waste: Plastic waste such as agricultural plastic films and pesticide containers can also be recycled and reused after being shredded.
