ANSWERS PDF 2026
▶ What are some controls to mitigate the hazards associated with powder
actuated tools? Answer: Visually inspect prior to use, proper training, use
recommended charges, if possible fire a test round, wear proper eye
protection, do not refire
▶ What are some common hazards associated with hand and power tools?
Answer: misuse and improper maintenance, falling flying abrasive, and
splashing objects or exposure to harmful dusts, fumes, mists, vapors, or
gases, wooden handles becoming loose and flying off,
▶ What are some controls to mitigate hazards associated with hand and
power tools? Answer: Keep all tools in good condition with regular
maintenance, use the right tool for the job, examine each tool for damage
before use, operate all tools according to the manufacturer's instructions,
provide and use the proper ppe
▶ What are some common hazards associated with asbestos exposure?
Answer: inhalation of fibers, insulation, floor tiles, vehicle brakes, - buildup
of scar like tissue in the lungs - disability or death
▶ What are some controls to mitigate asbestos exposure? Answer:
Employee exposure monitoring, training, regulate areas, control work
practices, ppe,
▶ What are some common hazards associated with lead exposure?
Answer: Lead dust or fumes cause brain disorders, anemia, nerve
disorders, high blood pressure, kidney disorders, reproductive disorders,
decreased red blood cells, slowed reflexes. Lead exposure may take place
in demo, salvage, removal, renovation, and cleanup
▶ What are some common controls to mitigate lead exposure? Answer:
Air monitoring, mechanical ventilation, administrative controls, ppe,
respiratory protection
, ▶ What are some common hazards associated with noise exposure?
Answer: chipping, hammering, grinding, drilling, generator, heavy
equipment, processes - cause hearing loss, impairment, temporary or
permanent
▶ What are some common controls to mitigate hazards created by noise?
Answer: Hearing protection, lo/to, training, hearing conservation program,
identify hearing protection zones, separate noisy work area, sound
absorbing material, limit exposure, avoid metal to metal contact, keep
equipment well maintained, identify areas that require hearing protection
▶ 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
