Q

To minimize employee exposure, each employer must have a written exposure control plan. The plan must be available to all employees whose duties may result in reasonably anticipated occupational exposure to blood or other potentially infectious materials.

A

bloodborne pathogens

21
Q

Protective measures in the clinical laboratory generally involve work practice and engineering controls focused on prevention of aerosolized particles, containment/isolation, and respiratory protection of N-95 (filtration of 95% of particles >0.3 μm) or better.

A

airborne pathogens

23
Q

which are used in numerous routine procedures, are among the most hazardous materials in the clinical chemistry laboratory because of possible fire or explosion.

A

flammable/combustible chemicals

24
Q

are injurious to the skin or eyes by direct contact or to the tissue of the
respiratory and gastrointestinal tracts if inhaled or ingested. Typical examples include acids (acetic, sulfuric, nitric, and hydrochloric) and bases (ammonium hydroxide, potassium hydroxide, and sodium hydroxide).

A

corrosive chemicals

25
are substances that, under certain conditions, can spontaneously explode or ignite or that evolve heat or flammable or explosive gases. Some strong acids or bases react with water to generate heat (exothermic reactions).
reactive chemicals
26
are substances that have been determined to be cancer-causing agents.
carcinogens
27
It is essential that only properly trained personnel work with radioisotopes. Good work practices must consistently be employed to ensure that contamination and inadvertent internalization are avoided.
personal protection
28
are also a concern in the clinical laboratory. Equipment often emits a variety of wavelengths of electromagnetic radiation that staff must be protected against through engineered shielding or use of PPE
nonionizing radiation
29
types of nonionizing radiation:
low frequency microwaves infrared visible spectrum ultraviolet
30
The fire triangle has been modified into a three-dimensional pyramid known as the
fire tetrahedron
31
classification of fires:
class A B C D
32
ordinary combustible solid materials, such as paper, wood, plastic, and fabric
class A
33
flammable liquids/gases and combustible petroleum products
class B
34
35

class C
36
combustible/reactive metals, such as magnesium, sodium, and potassium
class D
37
fire extinguishers used for class A fire:
pressurized water foam
38
fire extinguishers used for class B fire:
multipurpose-dry chemical carbon dioxide
39
fire extinguishers used for class C fire:
multipurpose-dry chemical carbon dioxide
40
fire extinguishers used for computer fire:

41
fire extinguishers used for class D fire:
sand or ceramic barrier material
42
how to use a fire extinguisher:
Pull Aim Squeeze Sweep
43
in event of fire, remember to:
Rescue Activate Confine Extinguish

which serve a number of functions in the laboratory, present a unique combination of hazards in the clinical laboratory: danger of fire, explosion, asphyxiation, or mechanical injuries.
compressed gas hazards
45
can result in death, shock, or burns. Indirect hazards can result in fire or explosion.
electrical hazards
46
is probably one of the most widely used cryogenic fluids (liquefied gases) in the laboratory
liquid nitrogen
47
equipment such as centrifuges, autoclaves, and homogenizers.
mechanical hazards
48
physical actions can, over time, contribute to repetitive strain disorders such as tenosynovitis, bursitis, and ganglion cysts.
