GUIDE *Q&A* (100% Correct) 2025/2026
|VERIFIED|
- What is the condition known as presbycusis?
Hearing loss due to old age
- What does presbyopia refer to?
Impaired vision as a result of aging, particularly difficulty focusing
- What is byssinosis and what industry is it associated with?
A disease caused by inhaling cotton fibers, also known as "brown lung disease" or "Monday
fever," common in the textile industry
- Which type of human error involves leaving something out during a task?
Omission
- How long must employers post OSHA citations after receiving them?
For 3 days or until corrected
- What does an audiogram measure?
It is a written record of hearing thresholds at specified frequencies
- What is an audiometer used for?
It is a device that can present tones of various frequencies at different volumes for hearing testing
- What dB level at 3000 Hz on an audiogram indicates hearing loss for a specific tone?
1
, 30 dB
- Which factors influence noise absorption?
Angle to the noise source, frequency of noise, density, condition of materials, type of mounting,
and shape of surface
- What material properties enhance noise absorption through engineering controls?
Good porosity, thickness, and air gaps
- What is emissivity?
It is the ratio of radiation emitted by a surface compared to a black body at the same temperature
- How does a bright metal surface compare in terms of emissivity?
It has low emissivity, less than 0.1, which makes it a good reflector and effective in reducing
radiant heat
- What is the emissivity of unpolished surfaces?
Close to 1.0, which is high and not ideal for reducing radiant heat
- Which nerve and hand areas are affected by carpal tunnel syndrome?
The median nerve affects the thumb, pointer, and ring fingers, with symptoms like wrist pain and
thenar wasting
- What condition is caused by brief high exposure to metal fumes, such as zinc or magnesium?
Metal Fume Fever, characterized by flu-like symptoms that appear 4 to 12 hours after exposure
- What effect does altitude have on fan horsepower and static pressure?
Altitude reduces the horsepower needed and static pressure but does not change the CFM or fan
RPM
2
,- What are the regulations for air supply in SCBA and airline respirators?
Air must be Grade D or higher, with acceptable oil content and filtering. Medical oxygen is
prohibited
- How do you define abduction and adduction in terms of arm movement?
Abduction increases the angle of the arm away from the body; adduction decreases it, bringing
the arm back toward the body
- What are the required air quality parameters for Grade D breathing air?
19.5%-23.5% oxygen, less than 5 mg/m3 of oil, less than 10 ppm CO, and less than 1000 ppm CO2
- What are the threshold limit values (TLV), permissible exposure limits (PEL), and IDLH for carbon
monoxide?
TLV: 50 ppm, STEL: 400 ppm; IDLH: 1500 ppm; PEL: 35-50 ppm, ceiling 200 ppm, instantaneous
1500 ppm
- What is carbon monoxide and how does it affect human health?
It is a colorless, odorless, flammable gas that reduces oxygen-carrying capacity in the blood,
causing chemical asphyxiation
- What is a teratogen?
An agent that causes malformation in an embryo or fetus without passing across generational
lines
- What is the next best alternative to electric forklifts for reducing emissions?
Converting the forklift to LP gas
- Under what conditions does double insulation fail to protect against shock?
When exposed to water or wet locations
3
, - What are the types of sampling methods in data collection?
Random, stratified, systematic, and cluster
- What does a pH less than 7 indicate?
An acid
- What does a pH greater than 7 indicate?
A base
- What is activated carbon and its main function?
A porous carbon used to absorb various odors and vapors, with a non-polar surface
- How do axial flow fans differ from centrifugal fans?
Axial flow fans provide high volume and low pressure drop, while centrifugal fans work better for
high pressures and have a perpendicular air flow
- What is the main difference between forward and backward blades in centrifugal fans?
Forward blades curve in the direction of rotation, while backward blades curve in the opposite
direction, making them more efficient
- When would a paddle wheel or long-shaving wheel be used?
For buffing exhaust or woodworking exhaust where heavy dust must pass through the fan
- What is the maximum travel distance for a fire extinguisher in light hazard occupancies?
75 feet, such as in churches, clubs, schools, and homes
- What are the inspection items for self-closing doors?
Lubrication on guides, non-bent binders, un-stretched chains, and no painted fusible links
