Definitions The following terms and acronyms are used in this procedure:
15-Minute
Occupational
Exposure Limit or
Short Term
Exposure Limit
(STEL)
A 15-minute time weighted average of airborne concentration of a
contaminant to which it is believed that workers can be continuously
exposed for a short period of time without suffering from irritation,
chronic or irreversible tissue damage, dose-rate dependent toxic
effects, or narcosis of sufficient degree to increase the likelihood
of accidental injury, impaired self-rescue or materially reduced
work efficiency.
Bump Test A field test conducted according to Suncor schedule. The test
ensures the detector is working properly.
During a bump test, the detector is exposed to a known concentration
of calibration gas. If the detector responds within predetermined
limits, the instrument is ready for use.
Ceiling Occupational
Exposure Limit
(Ceiling)
The concentration of a substance that must not be exceeded at
any time. The limit is indicated by a “C” in the column entitled “15
minute or ceiling occupational exposure limit” in Schedule 1,
Table 2 of the Alberta Occupational Health & Safety Code.
Immediately
Dangerous to Life or
Health (IDLH)
Circumstances in which the atmosphere is deficient in oxygen or
the concentration of a harmful substance in the atmosphere:
• is an immediate threat to life
• may affect health irreversibly
• may have future adverse effects on health
• may interfere with a worker’s ability to escape from a
dangerous atmosphere.
Lower Explosive
Limit (LEL) The lower value of the range of concentrations of a substance at
which, in a mixture with air, it may ignite.
Occupational
Exposure Limit
(OEL)
An upper limit of airborne concentrations of various contaminants
in the workplace. Typically, Occupational Exposure Limits are
airborne concentrations averaged over an 8 hour work day and
are reported as time weighted average concentrations.
Self-Test This test is performed by pressing the test button (blue button)
once every 24 hours. This test verifies proper functioning of the
electronic circuitry, battery and the visual alarm lights. A self-test
does not verify the sensor’s response to target gas.
Time Weighted
Average Exposure
(TWA)
The average exposure to a contaminant or condition to which
workers may be exposed without adverse effect over a period of
time.

3. Self-Test Fail
Step
Action
3.1 If the self-test fails, the detector emits five short beeps and flashes before
displaying a blank screen. The LCD then returns to the normal operating screen
and again displays “Test”.
Repeat the self-test.
Note: If the self-test fails three consecutive times, the LCD displays a blank
screen and the detector deactivates. Obtain a replacement monitor from
the tool crib.
4. Bump Testing the Personal Gas Monitors
Step Action
4.1 Ensure bump testing is performed at least once per shift cycle. Bump test stations
are located in most operating areas across site. Any of these bump test stations
can be used.
Note: Each bump test station is gas specific. Ensure that H2S and SO2personal
gas monitors are bump tested in correspondingly labeled test stations.
4.2 Ensure the unit is turned on (see Step 1.1). Ensure the front of the monitor is clear
of debris which may interfere with sensor operation.

Displaying the Gas Alarm Set points
Press to display the alarm set points.
Alarm set points are factory configured and cannot be modified.
Maximum Gas Exposure
The detector records the maximum gas exposure that triggers an alarm condition and begins calculating the
number of hours from when the maximum exposure occurred.
For each new exposure greater than the current maximum exposure, the detector resets the maximum gas
exposure to the new level and resets the hours to 0. After 24 hours of gas readings in the acceptable range, the
detector resets both values to 0.
Viewing the Maximum Gas Exposure
Press within 24 hours of receiving a gas alarm. The LCD displays the following:
