1.0 Purpose
To define Entrance Procedures for Physical Plant staff and Contractors and any other
ancillary staff that may enter Radioisotope Laboratories or Radioisotope Areas as a part
of their duties. Prescribed entrance procedures are required to reduce or eliminate
exposure to potentially harmful radioactive material to support or service personnel
(Physical Plant, Security Services and Contractors) and to limit the spread of radioactive
contamination.
2.0 Policy
Areas permitted to use or store radioactive material shall be labelled in manner to identify
the potential presence of radioactive material. Physical Plant staff, Contractors and any
other ancillary staff shall not be allowed to enter areas, dispose or work with equipment
or in areas where radioactive material has been used or stored without a documented
decommissioning, unless:
a)
They have documented training to ensure they understand the risks and
can identify and mitigate the hazards.
b)
They are accompanied by someone that is trained to recognize the hazard
signage and able to supervise the safe performance of activities in regards
to the radioactive materials.
3.0 Definitions
Permit Holder The Permit Holder or Responsible User is the person whom applies
for an Internal Radioisotope Permit. See the Terms of Reference (RSP-120) for
specific responsibilities.
Laboratory Radiation Supervisor (LRS) Is a Designated Worker (person
permitted to use radioactive material) nominated by a Permit Holder to assist the
Permit Holder to carry out his duties as specified in this manual. The LRS is
noted on the Permit.
“LRS” Laboratory Radiation Supervisor
“EHSO” Environmental Health and Safety Office
Radiation Warning Symbols The radiation warning symbols shall be
used as outlined in RSP-410 and RSP-510 to identify all areas where
radioactive material are used or stored.

Radioactive Contamination Radioactive contamination is the presence of
radioactive materials in any place where it is not desired, in particular where its
presence may be harmful. Contamination may present a risk to a person’s health
or the environment. Contamination has also been determined to be the cause of
failed experiments. Control of contamination is one of the key concerns
whenever radioactive materials are used.
Contractors Non-Physical Plant staff that provide service or construction work as
authorized by Physical Plant, EHSO or Academic Departments.

4.0 Responsibilities
4.1
All Departments (Physical Plant, Security Services, Administrative or
Academic) are responsible to ensure that Departmental staff and Contractors who
work in areas radioactive materials are permitted, or direct the work of others
these areas are:
a)
Trained to recognize the hazard signage and perform their duties
safely in regards to the radioactive material, or
b)
Accompanied by staff that are trained to recognize the hazard
signage and able to supervise the safe performance of activities in
regards to the radioactive materials.
c)
Supervised to ensure that safe procedures are followed and
prescribed personal protective equipment is worn as prescribed in
this procedure.
4.2
The Environmental Health and Safety Office is responsible to communicate to
all Departments the requirements as set out in this procedure.

5.0 Entrance Procedure for Radioisotope Laboratories
or Areas
Departmental staff (Physical Plant, Security Services, Administrative or Academic) and
contractors are to look for the Door Sign: “Radioisotope Laboratory” or “Radioisotope
Area” that is required to be posted on every entrance to a room or enclosure where
radioactive materials are permitted to be used or stored. The Door Sign will indicate
either “caution” or “no admittance”
5.1
If the room is signed “caution”:
a)
b)
Look for areas or equipment marked with the Radiation Warning
Symbol.
Talk to the Permit Holder or LRS (Laboratory Radiation Supervisor) as
indicated on the Door Sign and have the radioactive material moved away
from the area in that you will be working.
c)
Apply the Principals of Radiation Safety to reduce your potential exposure
to radiation.
1) Limit the time you spend close to the radioactive material, and
2) Increase your distance from areas or items labelled with the
Radiation Warning Symbols. For the types of radioactive
materials in use at the University, 2 metres is considered an
adequate safety zone. It is safe to be within 2 metres for a short
period of time.
3) Stay on the outside of any shielding to reduce your exposure.
4) Use PPE and good hygiene to limit the possibility of becoming
contaminated or spreading contamination.
d)
To enter a room marked “caution” and visually inspect, Personal
Protective Equipment would not normally be required. If in doubt, get
information from lab staff as indicated on the door sign or EHSO.
e)
Do not work on equipment or any installation marked with Radiation
Warning Symbol prior to contacting ESHO-Radiation Safety Office
(RSO).

f)
If the work is an emergency and it is not possible to contact the RSO. Use
the Full/Maximum Personal Protective Equipment in Section 6 and use the
Procedure as outlined in Section 7.
g)
To contact EHSO-RSO during Regular hours 789-3613 or 789-3359 or
474-6633 and asked to have RSO paged. After hours, contact Security
Services (474-9341) and indicate a “Radiation Safety Emergency”.
If the room is signed “no admittance”
1.
Contact Radiation Safety prior to entering room for a
decommissioning and a specific work procedure for the
project prior to entering room, or
2.
Use the Full/Maximum PPE in Section 6 and Procedure as outlined in
Section 7. In the event of an emergency where there is impending
injury, loss of life or major damage/loss of property, immediate
access to restricted areas without Personal Protective Equipment
is appropriate. Where possible, efforts to confine the spread of
possible contamination are indicated. During such access,
handling or tampering with labelled radioactive materials is not
allowed. All such instances shall be reported to the EHSO-RSO
without delay.

6.0 Full/ Maximum Personal Protective Equipment
All Personal Protective Equipment should be collected after use, sealed in a bag or pail
and given to EHSO-RSO in case it has radioactive contamination.
a)
b)
Lab coat, apron or overalls (disposable or washable) required minimum.
Recommended: Tyvek suit.
Gloves: re-useable chemically resistant gloves recommended. Use thicker
gloves when physical hazard is also present. Disposable gloves are
required if radioactive contamination is a possibility and may be worn
under or over reusable gloves.
c)
Safety glasses, goggles or face shield are required if there is any
possibility of projectiles, dust, aerosols or splashes such as when
drains or vents are being opened.
d)
Respiratory protection required if procedure has any risk of producing
dusts, hazardous vapors or aerosols. IF drains or vents are being
opened or there is any other risk of dust, vapors or aerosols being
generated: Combination Hepa/multi- contaminant respirator
required.
