CC PART 5 (PPE & HAZARDS) Flashcards
● The type of PPE used will vary based on the level of precautions required, such as standard and contact, droplet or airborne infection isolation precautions the patient room and closing the door.
DONNING (PUTTING ON)
The procedure for putting on and removing PPE should be tailored to the specific type of PPE.
DONNING (PUTTING ON)
● Fully cover torso from neck to
knees, arms to end of wrists, and
wrap around the back
● Fasten in back of neck and waist
Gown
● Secure ties or elastic bands at
middle of head and neck
● Fit flexible band to nose bridge
● Fit snug to face and below chin
● Fit-check respirator
Mask or respirator
Place over face and eyes and adjust to fit
Goggles or face shield
Extend to cover wrist of isolation
gown
Gloves
DONNING SEQUENCE
- Gown
- Mask or respirator
- Goggles or face shield
- Gloves
READ:
USE SAFE WORK PRACTICES TO PROTECT YOURSELF AND LIMIT THE SPREAD OF CONTAMINATION
● Keep hands away from face
● Limit surfaces touched
● Change gloves when torn or heavily contaminated
● Perform hand hygiene
● There are a variety of ways to safely remove PPE without contaminating your clothing, skin, or mucous membranes with potentially infectious materials
DOFFING (REMOVAL OF PPE)
● Remove all PPE before exiting the patient room except a respirator, if worn. Remove the respirator after leaving the patient room and closing the door
DOFFING (REMOVAL OF PPE)
Remove PPE in the following sequence:
- Gloves
- Goggles or Face Shield
- Gown
- Mask or Respirator
___________________________or immediately after removing all ppe perform hand hygiene between steps if hands become contaminated and immediately after
Wash hands or use an alcohol-based hand sanitizer
● According to compatibility
● Storeroom should be isolated in an area that is not used
for routine work
STORAGE OF CHEMICALS
Records must be kept for the length of employment plus
30 years
RECORD KEEPING OF PERSONNEL DATA WORKING WITH RADIOISOTOPES
Why are records kept for 30 years for those medical workers who worked in nuclear medicine or those exposed in radiation?
Because they are prone to developing cancer
Equipment that emits a variety of wavelengths of electromagnetic radiation that must be protected against through engineered shielding or use of PPE

Red Diamond (top)
Will not burn
Flammability
Yellow Diamond (right)
Stable
Instability
Can cause significant irritation
Can cause temporary incapacitation or residual injury
Can cause serious or permanent injury
Can be lethal
Health
White Diamond (bottom)
__ = unusual reactivity with
water
___ - oxidizer
Special hazards
W = unusual reactivity with
water
OX - oxidizer
Must be preheated for ignition to occur
Must be heated or in increase
ambient temperature to burn
Can be ignited under almost all
ambient temperatures
Will vaporize and burn at normal
temperature
Flammability
Increased temperatures makes unstable
Violent chemical change at
increases temperature or pressures
May explodes from increased
temperature or shock
Instability
Glacial acetic acid, hydrochloric acid, sulfuric acid, nitric and sodium hydroxide
Corrosives
Visible destruction of human
tissues (skin and eyes) on contact. Can cause injury on inhalation or contact
Corrosives
Interfere with metabolic processes when ingested,
inhaled or absorbed through
skin
Toxic substances
Capable of causing cancer
Carcinogen
Chemicals with pH <2 or >12.
Separate in organic acids from organic acids. Concentrate acids & bases can generate large amounts of heat when mixed with water
Corrosives
Cyanides (perfect toxic agent because it is both colorless and odorless), sulfides
Toxic substances
Threshold limit values (TLVs) = safe level of exposure
Toxic substances
Benzidine, formaldehyde
Carcinogen
OSHA requires monitoring of
formaldehyde exposure
Carcinogen
Induce genetic mutations
Mutagens
Benzene, Lead (Associated with
Basophilic Stippling, Jeepney drivers and Plumbism), Mercury (Minamata disease), radioactive material, toluene
Mutagens
Teratogen
Special precaution during pregnancy
Mutagens
Teratogen
Cause defects in embryo
Teratogen
May cause fire
Ignitables
Acetone, alcohols, ether. Xylene
Ignitables
FLASHPOINT: lowest temperature that produces ignitable vapor
Flammables: < 100 F
Combustibles: ≥ 100 F
Ignitables
Flammables: < ___ F
Combustibles: ≥ ___ F
Flammables: < 100 F
Combustibles: ≥ 100 F
May cause explosion
Mixture of oxidizing agents
such as peroxides and reducing
agents such as hydrogen generates head and may
explode
Reactives
Ether forms explosives peroxides on exposure to air or light
Store in explosion proof refrigerator,
Perchloric acid may react explosively with organic compounds
Reactives
Ether, Perchloric acid, Picric acids,
sodium azide
Reactives
Separate from other acids
Picric acids is shock sensitive when dehydrated
More powerful than TNT
Sodium azide solutions can for
explosive lead or copper azides in
drains.
Reactives
On the NFPA Hazard Diamond, 2 means what?
Moderate hazard
Which of the following chemicals is capable of causing cancer?
a. Glacial acetic acid
b. Cyanide
c. Benzidine
d. Lead
c. Benzidine
Xylene, ethanol, methanol, and acetone would be in which hazard class?
a. Corrosive
b. Flammable
c. Oxidizer
d. Carcinogen
b. Flammable
The flash point of a liquid may be defined as the:
a. Minimum temperature at which self-sustained ignition will occur
b. Maximum vapor pressure at which spontaneous ignition will occur
c. Temperature at which an adequate amount of vapor is produced, forming an ignitable mixture with air at the liquid’s surface
d. Temperatures that is 10° greater than the liquid’s boiling point
c. Temperature at which an adequate amount of vapor is produced, forming an ignitable mixture with air at the liquid’s surface
