People who work around chemicals may also be at an increased risk for hazardous chemical injury. Some of the most common chemicals causing injury or death include carbon monoxide, ammonia, chlorine, hydrochloric acid, lead, mercury, fluorides, ozone, zinc, cadmium, and sulfuric acid. These chemicals can take liquid, gas, or even solid form.
Many of these chemicals can be colorless, clear, and even odorless, making them difficult to identify if they are not contained in a properly labeled container. Exposure can cause sudden illness or even death; however, in other cases, it may take long-term exposure before an injury becomes evident. Exposure to caustic chemicals can also cause burning to the skin, eyes, mouth, and lungs.
