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.

acute exposures	Exposure that occurs suddenly or over a short period of time. Acute exposure occurs either once or a few times within a very short period.
aprons	A fluid-resistant or impermeable cover that shields the torso to the mid-calf. Aprons provide protection against exposure of the body to hazardous materials.
benzene	An organic chemical compound that is often used as a solvent. Benzene is hazardous.
biological hazards	Naturally occurring substances that may be harmful to employees. Biological hazards may include mold, human waste, or bloodborne pathogens.
bloodborne pathogens	Hazards carried by the blood. Employees may be exposed to bloodborne pathogens when another employee has an injury that results in bleeding.
cancer	Any type of the various malignant cells that surround and invade nearby tissue. Carcinogens in MWFs have been greatly reduced.
chemical hazards	Substances, mixtures of substances, or synthetic substances that are harmful to employees. Harmful chemicals may occur in the form of liquids, vapors, fibers, or dust.
chronic exposures	Exposure that occurs over a long period of time. Chronic exposure to even small amounts of a hazard can cause injury or illness over time.
coating	A finish used for protective and decorative purposes. Coatings like paint or varnish are applied to products in an industrial manufacturing setting as a component of the part creation process.
condensation	The liquid that has been converted from a vapor or gas. Condensation collects on cold surfaces when the air is humid.
dosage	The amount of exposure to a hazard. Higher levels of exposure usually cause greater harm.
duration	The length of time of exposure to a hazard. Breathing hazardous fumes for a few seconds is harmful, but breathing them for a few minutes may be deadly.
electromagnetic waves	Oscillating waves from magnetic fields. Electromagnetic waves are produced by the motion of electric charges such as electric current.
environment	The surroundings in a given place. The workplace environment consists of various components, including noise and air quality.
environmental components	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.
environmental hazards	Components in the workplace environment that can cause injury, illness, or death. Some hazards cannot be avoided.

ergonomic hazards	Physical factors within the environment that harm the musculoskeletal system. Ergonomic hazards include uncomfortable workstation height and poor body positioning.
evaporation	The vaporization of liquid into the atmosphere. A carrier typically evaporates from a coating mixture upon application to a surface.
exposure limits	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.
extremities	Any limbs of a human body. Extremities are often affected by vibration.
eye contact	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.
gloves	Protective hand covers that reduce the risk of injury and exposure to bloodborne pathogens. Latex gloves protect broken, burned, and abraded skin from bacteria.
hazard communication	The means through which employers inform their employees about hazards in the workplace. Means should include training sessions and the usage of SDS.
hearing protection	A type of personal protective equipment specifically designed to prevent hearing damage. Earplugs are the most common form of hearing protection.
helmet	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.
HIV	Human Immunodeficiency Virus. HIV is the virus that causes AIDS.
illness	Sickness or impairment that often affects a whole body or whole system, such as the lungs. Illnesses have many causes, including chemical exposure.
ingestion	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.
inhalation	Breathing in an airborne substance. Inhalation is one of the most common forms of exposure.
injury	Localized damage or harm. Injuries can be caused by events, such as accidents or physical trauma from something like repetitive motion.
