BSO PLUS SIX MONTH SAFETY REFRESHER TEST ANSWERS
September 2012
1.
Who is responsible for protecting you from workplace hazards?
a.
You
b.
Employer
c.
Supervisor
d.
All of the above
RATIONALE: Safety starts with the worker. However, employers and supervisors
must also take every precaution reasonable in the circumstances for the protection
of a worker. OSHA Section 25(2)(h) employer’s duties and Section 27(2)(c)
supervisor’s duties.
2.
Which of the following are “tools” we use to communicate and mitigate
hazards?
a.
Safety meetings
b.
Tool box talks
c.
TASC/JSA
d.
OBS (Observation-Based Safety)
e.
All the above
RATIONALE: These are tools and programs designed to help keep workers safe.
Results of a recent WSIB project show the Sarnia area is 25 times safer than the
rest of the province. These elements were cited as part of the reason.
3.
Which of the following actions will help minimize housekeeping hazards?
a.
Clean up after yourself throughout the day
b.
Store tools and materials in a clean and organized manner
c.
Only clean up at the end of a task
d.
Both a & b
RATIONALE: Effective housekeeping is an ongoing operation and is “maintained”
not achieved. Cleaning and organizing must be done regularly to prevent
workplace hazards. Everyone is responsible for maintaining a clean work space.
4.
Who must understand and sign the safe work permit prior to starting the
job?
a.
Operations, the team lead and the supervisor
b.
Every crew member working on the job
c.
Operations, the permit receiver and the safety attendant
d.
None of the above

The correct process for energy isolation is;
a.
Neutralize the energy, identify the energy source, verify “zero energy” and
physically prevent the energizing
b.
Identify the energy source, neutralize the energy, verify “zero energy”
and physically prevent the energizing by locking out the system
c.
Identify the energy source, physically prevent the energizing by locking out
the system, neutralize the energy, verify “zero energy”
d.
Both b & c
RATIONALE: This is the correct process for energy isolation. Operations
personnel have the overall responsibility for energy isolation. However, each trade
can put a lock on the machine and ask operations to verify “zero energy” prior to
starting work.
6.
Which of the following is NOT true of H2S?
a.
It is a colourless gas
b.
It can be found in low lying areas
c.
It has a rotten egg odour; therefore you can always rely on your sense
of smell to detect it.
d.
Affects your central nervous system, your ability to breathe, is highly toxic
and can kill you in seconds.
RATIONALE: H2S only has an odour at low concentrations and can irritate your
nose and throat. At moderate concentrations, your sense of smell is paralyzed and
you can no longer detect it by smell.
7.
Friable asbestos refers to asbestos which can be crumbled into dust by hand
pressure.
a.
True
b.
False
RATIONALE: This is a characteristic of friable asbestos. Once it becomes
airborne it can be inhaled into the body and pose negative health effects.
8.
Fall Prevention is always the best choice when working at heights.
a.
True
b.
False
RATIONALE: Fall prevention keeps you from reaching the hazard in the first place,
while fall arrest protects you once you have already fallen.
9.

RATIONALE: Your body sweats as a way of cooling you down. When your body
no longer has enough water to cool you down, you will stop sweating. This is a
sign of dehydration and can lead to heat stress.
10. The four personal states that lead to injury/incidents at work are:
a.
Rushing, irritation, fatigue, complacency
b.
Rushing, frustration, fatigue, boredom
c.
Rushing, frustration, fatigue, complacency
d.
Rushing, frustration, exhaustion, complacency
RATIONALE: These personal states of mind can lead to critical errors which can
then lead to a greater risk. A safety attendant who is in a state of fatigue is not
attentive or thinking about the task at hand. This could lead to an injury or even a
fatality. Remember to stop and think while you still have control.
11. Workers may refuse work if they have reason to believe the work is unsafe.
a.
True
b.
False
RATIONALE: OHSA Section 43.1

to believe that,
(a) Any equipment, machine device or thing the worker is to use or operate is likely
to endanger himself, herself or another worker.
(b) The physical condition of the workplace or the part thereof in which he or she
works or is to work is likely to endanger him or herself

of this Act or the regulations of the existence of any hazard of which he or she
know.
13. When using a stepladder, the highest rung you are allowed to stand on is…

RCF. RCF also has an MSDS.
18. The following are true regarding silica;
a. Silica-containing dust can be produced during such activities as grinding, jackhammering, concrete drilling, and abrasive blasting with sand
b. Silica dust will be released into the air so proper PPE should be worn when
performing these tasks.

Be made available to all workers by the employer
b.
Be less than 3 years old
c.
List a product’s hazardous ingredients

information about a hazardous substance, check your MSDS.
22. TASC cards should always be filled out in the lunchroom before work starts.
a.
True
b.
False
RATIONALE: TASC cards should be filled out at the job site before work starts to

working at height.
a.
True
b.
