Study Notes
Occupational Health and Ergonomics Q&A
-
Question 1: Dermatitis is the most common occupational disease.
-
Question 2: Exposure to petroleum products, grease, and solvents is most likely to cause dermatitis.
-
Question 3: Cumulative Trauma Disorders (CTDs) are disorders resulting from repeated movements over time, affecting body parts, and leading to a cumulative effect on the individual.
-
Question 4: The Lift Index for a 22lb weight, with a 16lb recommended weight limit, is 1.375
-
Question 5: Pocket dosimeters measure employee exposure to radiation.
-
Question 6: The volume fraction of 18.9 ft³ carbon dioxide (CO2) in a 20 x 20 x 10 ft container is 0.006.
-
Question 7: Increasing air velocity increases heat transfer rates through convection.
-
Question 8: Dilution ventilation is suitable for situations involving air contaminants that are not highly flammable or toxic and are not produced at a high rate.
-
Question 9: The concentration of solvent vapor in a room, after 2 hours, at a rate of 0.9 ft³/min with a ventilation rate of 1,500 ft³/min is 0.06ppm, under standard temperature and pressure (STP) conditions.
-
Question 10: A key factor in local exhaust system design is to ensure the system effectively removes all emitted contaminants, with the exhaust air volume flow rate being proportional to the contaminant generation rate.
-
Question 11: A worker exposed to 95dBA for 5 hours has a noise dose of 125%.
-
Question 12: The noise dose expressed in percentage of the OSHA permissible exposure level for the provided periods and levels is not provided in the given context.
-
Question 13: Cochlea is the primary part of the inner ear.
-
Question 14: The primary factor damaging hearing in noise-induced hearing loss (NIHL) is high-frequency noise.
-
Question 15: Noise-induced hearing loss (NIHL) depends on sound intensity and exposure time.
-
Question 16: Radioisotopes of a given material have the same atomic number but differing atomic masses.
-
Question 17: It will take 15.2 days for Radon 222Rn86 to reduce to 1/16 of its initial gram quantity.
-
Question 18: At twice the distance, the radiation level measured will roughly be one-quarter the initial level, resulting to 0.015 rem.
-
Question 19: A Geiger-Mueller radiation measuring instrument can be used to measure Gamma Rays, Alpha Rays, and beta rays.
-
Question 20: Erythema is caused by overexposure to sunlight.
-
Question 21: Loss of vision, or scotoma, in a portion of the visual field is most likely due to exposure to infrared radiation.
-
Question 22: Simple asphyxiants prevent normal hemoglobin function, reducing the availability of oxygen in the body, and they can also reduce oxygen concentration.
