Environmental Safety Hazards 241
Environmental Safety Hazards details the risks of chemical, biological, physical, and ergonomic hazards in the work environment. Hazard exposure can cause injury and illness, causing short- and long-term effects. Many hazards can be detected using the senses, but special equipment is sometimes necessary. There are many forms of hazard communication, including SDS. Using PPE diminishes risks posed by exposure to environmental hazards. There are government agencies that help assure employees’ safety by creating standards and legislation and studying hazards. However, the employer is ultimately responsible for providing a safe and hazard-free environment.
Awareness of environmental safety hazards can prevent employee injury, reducing time off and workplace accident rates. After taking this course, users will be able to identify various hazards in the workplace and their possible effects on the human body.

The factors that make up an environment. In the workplace, these include noise, air quality, machine vibration, workstation height, and any materials contacting the employee.
Components in the workplace environment that can cause injury, illness, or death. Some hazards cannot be avoided.
Environmental Protection Agency
EPA. The government agency responsible for administrating laws to control and reduce the pollution of air, water, and land systems. The EPA carries on federal research, monitoring, standard-setting, and enforcement activities to ensure environmental protection.
Physical factors within the environment that harm the musculoskeletal system. Ergonomic hazards include uncomfortable workstation height and poor body positioning.
The vaporization of liquid into the atmosphere. A carrier typically evaporates from a coating mixture upon application to a surface.
The maximum amount or concentration of a hazard that can be present or that a worker may experience without causing a health hazard. Exposure limits are tested using sophisticated collection and measuring equipment.
Any limbs of a human body. Extremities are often affected by vibration.
Absorption by or direct physical touching of the eyes. Eye contact with liquid and gaseous forms of chemicals can damage a person's vision.
general duty clause
A statement contained within OSHA's standards that requires employers to furnish employment and places of employment which are free from recognized hazards to the health and safety of their employees. The general duty clause covers situations for which there is no specific standard.
Protective hand covers that reduce the risk of injury and exposure to bloodborne pathogens. Latex gloves protect broken, burned, and abraded skin from bacteria.
The means through which employers inform their employees about hazards in the workplace. Means should include training sessions and the usage of SDS.
A type of personal protective equipment specifically designed to prevent hearing damage. Earplugs are the most common form of hearing protection.
A protective head covering that shields an employee's head from falling debris and other types of hazards. A helmet may be required in environments where work is being done overhead.
Human Immunodeficiency Virus. HIV is the virus that causes AIDS.
Sickness or impairment that often affects a whole body or whole system, such as the lungs. Illnesses have many causes, including chemical exposure.
To take into the body by means of swallowing or absorption. Chemical and biological hazards can be ingested when they settle on food, drinks, skin surfaces, or clothing.
Breathing in an airborne substance. Inhalation is one of the most common forms of exposure.
Localized damage or harm. Injuries can be caused by events, such as accidents or physical trauma from something like repetitive motion.
The process by which two or more substances produce a new substance. When chemicals or medicines interact, they may become hazardous.
The reaction created when two or more substances are combined. Some interactions can cause substances to become hazardous.
A protective, full-body covering to shield an employee from hazardous materials. A jumpsuit can be useful when welding in extreme situations.
