1. INTRODUCTION

Personal, direct reading gas monitors are an important tool used daily throughout the Plant to
detect and monitor atmospheres for safe work.

2. SCOPE & PURPOSE

This standard specifies the selection, use, specification and care of personal gas monitors at Q-
Chem in order to protect the health and safety of the individuals carrying them. Q-Chem in this
standard refers to Q-Chem, Q-Chem II and RLOC facilities.

3. DEFINITIONS

 Bump Test – A verification test of the gas detectors calibration using a test gas of known
concentration to “bump” the sensors into alarm states.
 Calibration – The adjustment of the gas detectors reading to coincide with a known
concentration (generally a certified standard) of test gas.
 DSR - Designated Site Representative
 FSC - Fire and Safety Coordinator
 Personal Gas Monitor (e.g. H2S & SO2 detector) – A device worn by a person that
measures airborne gases and provides a warning when alarm levels of hazardous gases are
reached.
 SCBA – Self-Contained Breathing Apparatus

4. PROCEDURE

4.1. General Requirements

i. The Safety Department/Industrial Hygienist shall approve all personal gas monitors used on
site.

4.2. Issuing of Personal Gas Monitors

i. Personal gas monitors are available in the Materials Warehouse under stock item number
501698 for H2S and 507504 for SO2 detector.
ii. The Materials Warehouse shall not issue any personal gas monitors directly to employees.
An employee can obtain a new device as per the following procedure:
a) The employee’s supervisor shall send an email to the Industrial Hygienist with the
following details:
 Employee Name
 Staff Number
 Unit / Department
 Cost Centre and G/L Account
b) The Industrial Hygienist shall withdraw the required quantity of devices from the
Materials Warehouse.
c) The devices shall be registered into the gas monitor database by the Industrial Hygienist.

d) The Industrial Hygienist shall notify the end user to collect when ready.

4.3. Personal Gas Monitors for Visitors / Call-off Hire

There are some cases where certain departments bring in vendors, guests or call-off
personnel to site. Personal gas monitors (when required) shall be managed and issued as
follows:
i. The host department shall stock and maintain an appropriate quantity of personal gas
monitors that can be issued to the vendor/visitor/call-off employee when required.
a) These can be withdrawn from the Materials Warehouse following the same procedure
described above. No employee name/number is required.
b) It is the duty of the host department to register these devices in advance with the
Industrial Hygiene Section.
ii. The IH Section will provide each monitor with a unique identification number.
iii. The host department/DSR shall maintain a register/log book whereby they track the details
of whom these monitors are issued to when used. The minimum information required shall
include the following:
a) Name of employee / guest
b) Job title / position
c) Company name
d) Gas monitor number (Department-specific number)
e) Date & time issued
f) Date & time returned
g) Employee signature
iv. It is the responsibility of the host department to ensure the end-user follows all usage
requirements as indicated in this standard.

4.4. Use of Personal Gas Monitors

i. Personal gas monitors shall be worn where hazard identification and risk assessment
identifies the requirement.
ii. Personal gas monitors shall be used as per the requirements of this standard.
iii. Personal gas monitors shall be worn within the worker’s breathing zone.
a) The breathing zone is within a 25cm (10 inch) radius of the worker's nose and mouth.
b) Personal gas monitors shall only be attached to the front of the body (e.g. pocket, collar
or lapel).
iv. Alarm settings shall be set as per manufacturer’s instructions.
a) Whenever possible, changes shall be locked out and only performed by authorized
personnel.
b) Settings shall be in accordance with Q-Chem adopted exposure limits.

Instrument Alarm Settings

Gas Name
Low High
Hydrogen Sulfide (H2S) 10 ppm 15 ppm
Sulfur Dioxide (SO2) 2 ppm 4 ppm

v. When a monitor goes into alarm, it is indicating there may be a dangerous environment
present.
a) The wearer shall ensure the work area is evacuated immediately and in a safe manner.
b) Work shall not continue in the area until the source of the alarm has been identified and
controlled.
c) The alarm event and any corrective actions shall be communicated to the Industrial
Hygienist and documented.
 The instruments data shall be downloaded into the device-specific database
management software.
 Fire and Safety Coordinator (FSC) shall download the data after hours.

NOTE
Personal gas monitors should not be worn while donning SCBA or Airline
Respirators to perform planned work on equipment expected to contain
high H2S/SO2 concentrations. Exposure of the device to such high
concentrations could damage the sensor. The gas concentration should
be measured in such instances with the portable multi-gas detectors.

4.5. Bump Testing

i. Personal gas monitors shall be bump tested prior to being put into service and before each
use (See Appendix I for procedure).
ii. Personal gas monitors that are used only occasionally shall be bump tested at least
monthly to ensure they continue to remain functional.
iii. Bump testing records shall be downloaded at quarterly intervals.
iv. Personal gas monitors which fail the bump test shall be removed from service and sent to
the Industrial Hygienist for inspection.

4.6. Bump Stations

i. Bump stations are located at strategic points throughout the facility; you can do a bump test
at any of the locations (See Appendix II for locations).

4.7. Care of Personal Gas Monitors

i. Personal gas monitors shall be cleaned and stored according to the requirements of this
standard.
a) Do not substitute any components.
b) Do not activate the detector after the date on the package.
c) Ensure the sensor grill is free of dirt, debris and is not obstructed.
