Mesothelioma and Heavy Equipment Mechanics
Heavy Equipment Mechanics Including Diesel and Mesothelioma
In their last release, worksafebc.com reports two cases of heavy equipment mechanics who succumbed to mesothelioma in the last one year. Another report cites the case of a 78-year old mechanic who developed malignant mesothelioma because he was exposed to asbestos dust from the spray-on insulation that was used on hangar doors.What Is Asbestos?
Asbestos is highly carcinogenic. Heavy equipment mechanics carry unusually high risks of exposure to asbestos. They are called upon to diagnose, maintain, and repair heavy equipment used in industrial work, logging, and construction. They inspect and diagnose mechanical problems occurring in boilers, bulldozers, stripers, graders, mowers, automobiles, and trucks. They overhaul diesel and gas engines and repair a wide range of engine parts like gears, shafts, bearings, steering and suspension systems, and brake drums.Most of the machine parts they deal with contain varying amounts of asbestos in them. Machine linings usually contain asbestos and grinding these linings produces very fine dust particles that remain suspended in the atmosphere.
Jason Hoe, a heavy equipment mechanic explains, “Our work is very hands-on. We break things apart and put them back together after repair. So it is not unusual for us to walk through piles of white dust on any working day. Many of us even sweep our work areas clean at least two times a day because the dust gets about an inch thick.”
Heavy equipment mechanics usually perform their duties in an enclosed service garage, although they also work at construction sites, plants, and factories. As a natural part of their work, they grind and cut machine parts that produce a fine white dust. This dust usually contains thin asbestos fibers that float in the air because they are very light. These fibers stick to surfaces and are easily taken in through the nose and mouth. Once they reach the lungs, they stick to the surface of the lungs and lead to a number of asbestos-related diseases that may ultimately lead to death.
