Contractors frequently work with a wide variety of chemicals to carry out their work. More often than not, these chemicals are hazardous to human health, and they can cause injury if handled incorrectly. In fact, in the United States alone, more than 50,000 fatalities are reported annually due to workplace exposure to hazardous chemicals. If you own a contractor company, it is your responsibility to make sure that your company abides by all chemical safety standards and regulations and that your employees are properly trained for handling hazardous chemicals.
Risks of Handling Hazardous Chemicals
You should always perform thorough research about a chemical before working with it. The detrimental effects of a chemical may not be obvious during exposure, and this is why it is so important to understand the side effects beforehand.
The health risks posed by hazardous chemicals depend on a variety of factors. First, the degree of risk depends on the chemical itself. Second, the risk depends on how long and in what manner a person is exposed to a chemical. Lastly, the risk depends on whether a person is wearing any personal protective equipment (PPE) when exposed to a chemical.
Chemical Assessment Risk Terms:
- Ceiling Limit: The maximum amount a worker can be exposed to a chemical.
- Short-Term Exposure Limit (STEL): The average exposure to a chemical to which a worker may be exposed during a short time period (typically 15 – 30 minutes).
- Time-Weighted Average (TWA): The acceptable average exposure to a chemical over a given period of time, typically 8-hours.
The OSHA Occupational Chemical Database is an important resource for learning about different chemicals and their corresponding safe exposure times.
Overexposure to hazardous chemicals, as well as improper use of PPE when handling hazardous chemicals, can pose a wide variety of short- and long-term side effects. The list of hazardous chemicals is virtually endless, but here are three common examples.
- Chemical Exposure to PVC: PVC, or polyvinyl chloride, is commonly used to coat pipes and provide insulation for electrical wiring. If handled incorrectly, PVC can cause cancer, neurological damage, and reproductive damage.
- Exposure to Formaldehyde: Formaldehyde is often found in polymers used in plywood and carpet manufacture, and it also exists in resins. This chemical is a carcinogen, and it is an irritant to the body’s mucous membranes.
- Exposure to Silica: Silica commonly exists as dust, and it is a component of bricks, glass, and concrete. When inhaled, silica can cause chronic lung problems, lung cancer, and kidney cancer.
