Vocabulary for Exam 6 Flashcards
Is found in products as either the tetrasodium or disodium salt. They react chemically to “bind” calcium, which inhibits the blood clotting mechanism. It is a skin irritant, causing dryness and cracking.
Ethylenediamine Tetracetic Acid (EDTA)
Disease that may be transmitted between individuals, with reference to the organism that causes a disease.
Contagious Disease
An evaluation of exposures that are time-weighted over an established period. It allows the exposure levels to be averaged generally over an 8-hour time period.
Time-Weighed Average (TWA)
Uneven heartbeat.
Arrythmia
Having a higher lethal dose (as compared to highly toxic).
Toxic
Apparatus used for sterilization by steam presure, usually at 250oF/121oC for a specific time.
Autoclave
A carcinogen potentially produced when formaldehyde and sodium hypochlorite come into contact with each other. Normally occurs only in a controlled laboratory setting and requires a catalyst.
Bischloromethyl Ether (BCME)
OSHA required emergency safety device providing a steady stream of water for flushing the eye.
Eye Wash Station
To disperse as an aerosol; minute particles of blood and water become atomized and suspended in air when water under pressure meets the blood drainage or when flushing an uncovered flush sink.
Aerosolization
A specific eye, mouth, or other mucous membrane, non-intact skin, or parenteral contact with blood or other potentially infectious materials that results from the performance of an employee’s duties.
Exposure Incident
Requires employers to provide employees with information and training on hazardous chemicals in their work place at the time of their initial assignment, and whenever a new hazard is introduced into their work area.
OSHA Occupational Safety and Health Administration Act of 1986 (Right to Know Act)
Weakness in the extremities due to damage or degeneration of the peripheral nerves.
Peripheral Neuropathy
A cancer-causing chemical or material.
Carcinogen
A severe infectious bloodborne virus.
Hepatitis B Virus (HBV)
A central nervous system depressant which can cause symptoms including headache, lightheadedness, dizziness, drowsiness, fatigue. In high concentrations, stupor and unconsciousness can occur.
Narcotic
An unstable salt usually produced in an aqueous solution and used as a bleaching and disinfecting agent.
Sodium Hypochlorite
Legal limits established by OSHA to which workers can be exposed continuously for a short period of time without damage or injury. Exposures at this limit should not be more than 15 minutes and not repeated more than 4 times per work day.
Short Term Exposure Limit (STEL)
An agent which can cause non-inheritable mutations in offspring.
Teratogen
Difficult or painful breathing.
Dyspnea
Chemicals which will affect adversely certain organs.
Target Organ Effects
Controls that reduce the likelihood of exposure by altering the manner in which a task is performed; prohibiting recapping of needles, and not allowing blood splatter or aerosolization of blood while draining during the embalming process.
Work Practice Controls
Any comtaminated object that can penetrate the skin include, but not limited to:
- Needles
- Scalpels
- Broken glass
- Exposed ends of wires
Contaminated Sharps
Having a relatively low lethal dose.
Highly Toxic
In contaminated air, the parts of vapor or gas (formaldehyde) per million parts of air by volume; in solution the parts of chemical per million parts of solution.
Parts Per Million (ppm)
These levels are established to ensure adequate protection of employees at exposures below the OSHA limits, but to minimize the compliance burdens for employers whose employees have exposures below the 8 hour permissible exposure limit (PEL). The level for formaldehyde is 0.5ppm. Exposure limit usually one half of the Occupational Safety and Health Administration (OSHA) legal limit for a regulated substance.
Action Level (AL-Exposure Limits)
The presence of the reasonably anticipated presence of blood or other potentially infectious materials on an item or surface.
Contaminated
Human blood, human blood components, and products made from human blood.
Blood
OSHA required receptacle for proper disposal of sharps.
Sharps Container
Bleeding from the nose, a nosebleed.
Epistaxis
Causing visible destruction of living tissue at point of contact.
Corrosive
An agent or material exposing one to risk.
Hazardous Material
Procedures that isolate or remove the bloodborne pathogen hazard from the workplace such as sharps disposal container, self-sheathing needles.
Engineering Controls
Molecules of a compound in which the atoms have a slightly different configuration.
Isomers
Extreme sensitivity to light.
Photophobia
A major agency of the Department of Health and Human Services, with headquarters in Atlanta, Georgia, concerned with all phases of control of communicable, vectorborne, and occupational diseases.
Centers for Disease Control and Prevention (CDCP, CDC)
OSHA regulation limiting the amount of occupation exposure to formaldehyde gas. Went into effect May of 1988.
Formaldehyde Rule
