CHST EXAM REVIEW QUESTIONS WITH
ACCURATE SOLUTIONS 2026
▶ What is ionizing radiation? Answer: Radiation with enough energy to
detach electrons from atoms or molecules
▶ What is non-ionizing radiation? Answer: A series of energy waves
composed of oscillating electric and magnetic fields traveling at the speed
of light.
▶ What are some common hazards associated with ionizing radiation?
Answer: x-rays, industrial radiography (profile gauge), nuclear power
plants, radon in soil,
▶ What are some common controls to mitigate the hazards associated with
ionizing radiation? Answer: time, distance, and shielding
▶ What are some common hazards associated with non-ionizing radiation?
Answer: Sun, black light, welding arcs, uv lasers, excessive light, furnaces,
welding, lasers, incandescent bulbs, ovens, televisions, and some radars
▶ What are some common controls to mitigate non-ionizing radiation
hazards? Answer: Solid materials to block the sun, sunscreen, enclosures,
filters, distance
▶ What are some common hazards associated with silica exposure?
Answer: hazards created when cutting, sawing, sanding, drilling, or
crushing concrete, stone, rock, brick, mortar; sanding or drilling into
concrete walls, manufacturing bricks, stone counter tops, concrete blocks -
kidney disease, silicosis, pulmonary disease, lung cancer
▶ What are some controls utilized to mitigate hazards associated with silica
exposure? Answer: training, housekeeping practices, tools equipped
w/vacuums, atmospheric testing, ppe, respirators, water suppression
, ▶ What are some common hazards associated with chemical exposure?
Answer: spills, leaks, mislabeling, offgasing, air contamination, skin
contact, ingestion, airborne particulates
▶ What are some common controls to mitigate chemical exposure?
Answer: Safe material handling, proper storage, GHS, proper disposal,
regular inspection of processes, eliminate the chemicals, move workers
away from the area where chemicals are used/stored, provide ppe, lockout
tagout equipment that could expose workers to chemicals
▶ Where can thermal stress be a problem? Answer: boiler maintenance,
smelting operations, laundries, kitchens, foundries, brick firring, refrigerated
rooms or freezers.
▶ True or False: Thermal stress can be heat or cold. Answer: True
▶ What are the four basic sources of heat to the body? Answer: radiation,
convection, conduction and metabolic
▶ What are some hazards created by extreme temperatures? Answer:
Heat stress, heat rash, heat cramps, dehydration, heat exhaustion, heat
stroke (medical emergency), cold stress, frostbite, trench foot, hypothermia
▶ What are some common controls for mitigating the hazards create by
extreme temperatures? Answer: observance and adherence to the wind
chill factor, proper ppe, proper nutrition, fluid replacement, work/rest cycles,
layered clothing, buddy system, light clothing, avoid caffeine and alcohol,
training, heavies work in coolest part of the day. understand signs and
symptoms of heat related disorders, air conditioning, ventilation, fans,
▶ What are some common hazards associated with vibration and impact
exposures? Answer: grinders, saws, chipping hammers, sanders,
pavement breakers, impact wrenches all can cause hand arm vibration
injury. white finger
▶ What are some common controls to mitigate hazards created by
vibration and impact exposures? Answer: anti-vibration tools, anti-vibration
gloves, rest period, proper tool maintenance, proper tool for the job,
continuous exposure
