PART C Flashcards
Minimize employee exposure by either reducing or removing the hazards at the source or isolating the worker from the hazards
Engineering Controls
Include eliminating toxic chemicals and replacing harmful toxic materials with less hazardous ones, enclosing work processes or confining work operations, and installing general and local ventilation systems
Engineering Controls
Alter the manner in which a task is performed
Work Practice Controls
Following proper procedures that
- minimize exposures while operating production and control equipment;
- inspecting and maintaining process and control equipment on a regular basis;
- implementing good house-keeping procedures;
- providing good supervision; and
- mandating that eating, drinking, smoking, chewing tobacco or gum, and applying cosmetics in regulated areas be prohibited
Work Practice Controls
Include controlling employees’ exposure by scheduling production and workers’ tasks, or both, in ways that minimize exposure levels
Administrative Controls
Example, the employer might schedule operations with the highest exposure potential during periods when the fewest employees are present
Administrative Controls
5 Job Hazards
- Air Contaminants
- Chemical Hazards
- Biological Hazards
- Physical Hazards
- Ergonomic Hazards
Job Hazard
Commonly classified as either particulate or gas and vapor contaminants
Air Contaminants
Job Hazard
What are the most common particulate contaminants include
dusts, fumes, mists, aerosols, and fibers
Air Contaminants
Are solid particles that are formed from solid or inorganic materials by reducing their size through
mechanical process.
DUSTS
Air Contaminants
Are formed when material from a volatilized solid condenses in cool air
Fumes
Air Contaminants
Is a finely divided liquid suspended in the atmosphere
Mist
Air Contaminants
Are formless fluids that expand to occupy the space or enclosure in which they are confined
Gasses
Air Contaminants
Change into vapor and mix with the surrounding atmosphere through evaporation
Liquids
Job Hazard
Harmful chemical compounds in the form of solids, liquids, gases, mists, dusts, fumes, and vapors exert toxic effects by inhalation, absorption, or ingestion
Chemical Hazards
Job Hazards
These include bacteria, viruses, fungi, and other living organisms that can cause acute and chronic infections by entering the body either directly or through breaks in the skin
Biological Hazards
Job Hazards
Any occupations that result in contact with bodily fluids pose a risk to workers from ______ hazards
biological
Includes excessive levels of ionizing and nonionizing electromagnetic radiation, noise, vibration, illumination, and temperature
Physical Hazards
The science of _____ studies and evaluates a full range of tasks including, but not limited to lifting, holding, pushing, walking, and reaching
Ergonomic
Result from technological changes ; some problems arise from poorly
designed job tasks
Ergonomic Hazards
Rule _____, Occupational Health and Environmental Control
1070
Rule _____, Work Environment Measurement (WEM)
1077
Established the threshold limit values for toxic and carcinogenic substances and physical agents which may be present in the atmosphere in the work environment
1070 - Occupational Health and Environmental Control
The employer shall maintain and control the working environment in comfortable and healthy conditions for the purpose of maintaining and promoting the health of his
workers
1077 Work Environment Measurement (WEM)
