Crystalline silica is a common mineral in the earth's crust, and is found in many types of rock including sand, quartz, and granite. When you inhale crystalline silica, the lung tissue reacts by developing fibrous tissue around trapped silica particles. Silica is present in both work and non-work environments, and exposure to crystalline silica dust has long been known to cause a disease called silicosis.
OSHA states that you have the right to a safe and healthful workplace, free of serious recognized hazards. While we may think only the "obvious" hazards in our workplace are potentially dangerous, such as machinery, chemicals, noise, or traffic, there is something that is just as dangerous that we may not be aware of.
According to OSHA, caught-on or -between hazards collectively is one of the four deadliest dangers found on a construction site, and one of the biggest hazards for workers in industrial processing as far as unguarded machines and equipment. Workers' fingers, arms, hair, and other body parts as well as protective clothing can be caught or entangled in unguarded machine parts or equipment, which is known as a caught-in or -between hazard.
According to the U.S. Bureau of Labor Statistics, one-third of all workers compensation claims are due to ergonomic issues. Simply defined, ergonomics is the study of work. More specifically, it is the science of fitting the job to the worker, rather that forcing the worker's body to fit the job. This can be done in various ways, such as adapting work stations, tasks, tools, and equipment to fit the worker to reduce the physical stress and illness on the worker's body.
