According to the Environmental Protection Agency (EPA), “Hazardous waste is waste that is dangerous or potentially harmful to our health or the environment. Hazardous wastes can be liquids, solids, gases, or sludges. They can be discarded commercial products, like cleaning fluids or pesticides, or the by-products of manufacturing processes.” There is a growing awareness of the dangerous side effects of hazardous waste contamination. Years ago, many industrial plants discharged heavy metals and unstable organic compounds directly into streams or injected them into the earth’s subsurface through wells, causing illness in populations with close proximity to these toxic sites. This lesson teaches the industrial sources of land, air, and water pollution, the health dangers that environmental pollutants present, and the types of actions that industrial facility workers must complete in order to control industrial pollutants and respond to environmental incidents. -
In this course you’ll learn about the chemistry of Hydrogen Sulfide and how it is formed, the properties and characteristics of the gas, where Hydrogen Sulfide is likely to be located in your workplace, the potential health hazards of short term and long term H2S exposure, how to work safely with Hydrogen Sulfide and emergency response steps to take should you or a co-worker be exposed to this gas. -
The Occupational Safety and Health Administration (OSHA) has issued a final rule to curb lung cancer, silicosis, chronic obstructive pulmonary disease and kidney disease in America's workers by limiting their exposure to respirable crystalline silica. The rule is comprised of two standards, one for Construction and one for General Industry and Maritime. This lesson is designed to improve the safety of workers in environments where silica exposure hazards exist by increasing employee awareness of this hazard and by demonstrating how the hazard can be recognized and addressed in the workplace. -
The purpose of the NFPA standard 70E is to provide a standard for safety-related work practices for the construction, maintenance, operation and demolition of electrical systems in the workplace. This Overview covers awareness-level information for workers who have jobs or assignments that bring them into contact with electrical hazards, such as arc flash and electric shock. Completing this lesson does not designate an employee as an electrically-qualified worker. -
To protect you from the serious hazards posed by the unexpected start-up or operation of equipment during repair or maintenance, the Occupational Safety & Health Administration (OSHA) has established a Control of Hazardous Energy standard. It is commonly referred to as the lockout/tagout (LOTO), or energy isolation standard. This standard requires the application of markings and barriers that prevent unauthorized persons from energizing and operating equipment.Energy in any form becomes hazardous when it builds to a certain level or is released inadvertently or unexpectedly. Lockout/tagout refers to specific practices and procedures that safeguard employees from the unexpected startup of machinery and equipment, or the release of hazardous energy, during service or maintenance activities. -
