when approaching these hazards.
10. Equipment operators who drive on soft ground around designated walkways could create trip
& fall hazards:
a) True
b) False
RATIONALE: Tire tracks from heavy equipment can leave ruts in soft ground, which may lead to trip
injuries such as sprained joints and broken bones. Operators should avoid driving on soft ground
and pedestrians should be mindful of soft walking surfaces when there are no designated walkways.
11. More slips/trips/falls happen while working at the same level than from working at height.
a) True
b) False
RATIONALE: Statistics show that 65% of falls are from the same level compared to 35% of falls are

d) Some of the signs/symptoms include poor co-ordination, blue lips and fingers, reduced mental
alertness and shivering
e) None of the above
RATIONALE: These are all true of cold stress. Cold is a physical hazard and presents a very real
danger to workers. Prolonged exposure to cold eventually depletes the body’s energy reserves and
affects the brain’s ability to function properly. Never compound the risk by going off by yourself in
the cold.
14. Ergonomic hazards can lead to what type of injuries/illnesses?
a) Chemical burns
b) Sprains and strains to joints, muscles, ligaments and tendons
c) Slip and fall injuries
d) Lacerations and amputations

to muscles, tendons and ligaments.
15. Which factors determine the degree of an ergonomic hazard?
a) Repetition
b) Posture
c) Force
d) All of the above
RATIONALE: The frequency, duration, types of posture, and exertion required to perform tasks are
all potential ergonomic hazards, and must be assessed in order to ensure proper controls are
implemented.
