3. Introduction: The G2N Laboratories in a COVID-19 World

In accordance with the new safety protocols to mitigate the spread of the Covid-19

virus, the access and entry procedures to G2N has been modified. All users are required to

read the new procedures and acknowledge they have been provided this information and

understand the new procedures that have been implemented. The procedures and rules

described in this document are an addendum to the existing operating and safety policies

of the lab. The procedures are set up to maintain a safe working environment that is

intended to protect the researchers who use the facility. Any questions or concerns should

be directed Richard Barber, the G2N lab manager.

The following sections will detail the modified procedures for:

Access and entry to the cleanroom

The criteria for maximum occupancy as define by physical distancing requirements

The flow of movement within each section of the lab

Cleaning procedures for sanitizing surfaces

4. G2N Cleanroom Safety Addendum

In order to minimize potential contact between users and community spread of COVID-

19, new rules will be implemented effective immediately for access to the G2N cleanroom

facility.

The stations in the cleanroom will be cleaned on a regular basis, at least twice daily.

All surfaces associated with the station will be sanitized using alcohol-based disinfectant

(60%-70% isopropanol or ethanol) before beginning work for the day and when work has

concluded for the day. These surfaces include tabletops, keyboards, mice, instrumentation

faceplates, handles, buttons, knobs, cables, and power cords.

4.1. Access into Cleanroom and Maximum Occupancy Criteria

There is a maximum of 7 users in the clean room at any one time. Areas within the

clean room have posted Occupancy Limits. Lab users are required to observe these

occupancy limits while working in the clean room. Figure 1 shows the maximum

occupancy of areas within the clean room. The following procedures will be used to

minimize contact and maintain a safe working environment:

4.1.1. Users entering the clean room MUST BOOK LAB ACCESS IN

ADVANCE (using the online booking system) and provide specific schedules

for entering and existing the lab.

4.1.1.1. The G2N Equipment Booking System will only allow booking spaces

for 7 users.

4.1.2. Access time intervals (slots) are limited to 2 hours. You may book for

shorter times.

6

4.1.3. Requests for extended access time specified in 4.1.2 will be considered if

available slots exist after your final scheduled reservation. Requests need to

be sent to the lab manager in advance of the booking.

4.2. Foyer – Entry

In order to minimize contamination of surfaces and high touch areas in the foyer area

all personal outdoor garments (coats, hats, gloves, etc.) will no longer be allowed into the

foyer. Storage of these garments in the foyer is prohibited. In addition, storage of personal

items within the foyer, such as backpacks or purses, is also prohibited. Bring only what

you need in the clean room. During winter operation, do not change or store outdoor shoes

or garments in the foyer.

A message board in the foyer will provide daily announcements or any critical

warnings; check for messages on the board before proceeding with the gowning procedure.

This board may also be used by lab users to exchange updates and information. Users

should wear gloves before handling markers, which should be sanitized before and after

use.

The following procedures are required in addition to the previous standard gowning

process for entering the cleanroom:

4.2.1. Upon entering the foyer, the hand sanitizer provided at the entry, should be

used. Hands should be thoroughly sanitized for in accordance with the

approved procedure from the Safety Office (See Appendix 1).

4.2.2. Face masks are now required and will be available in the foyer before

entering the lab. Don a face mask.

4.2.3. Don new gloves that are available at the entry.

4.2.4. Safety goggles are required upon entry. All users will be assigned storage

of their own personal goggles in the foyer. DO NOT SHARE SAFETY

GOGGLES!

4.2.5. You may now enter the change-room area and continue with the gowning

process for entering the cleanroom.

4.3. Change Room – Entry

New change room procedures are in place to maintain physical distancing requirements

that will limit the number of persons in the change room. It is possible for 2 individuals (1

entering and 1 exiting) to maintain a 2-meter physical distance while using the change

room. To allow safe distancing, areas have been designated in the change room for

gowning and degowning. Researchers waiting to enter the clean room will stand at

designated locations at the foyer and entry hall way. They will enter the change room only

after they have observed the previous user exit into the clean room hallways. Once gowned

in normal clean-room apparel, users are allowed to enter the clean room in accordance with

the maximum number of users specified above. The following procedures should be

followed for donning lab garments:

4.3.1. Take a new hair cover from the dispensing area. Don the hair cover.

7

4.3.2. Take new shoe covers from the dispense area. Don them while crossing

over the step-over bench.

4.3.3. Take gloves from the dispenser. These gloves should go OVER the

gloves you are already wearing from the Foyer.

4.3.4. Don your stored clean room coveralls (be careful of handling nearby

coveralls in the air-shower storage closet) or take a new suit from the

cupboard. Don the suit.

4.4. Cleanroom Protocol

After fully gowning into the clean-room attire, the physical distancing requirements in

the clean-room must be maintained and followed. You must maintain a two (2) meter

SEPARATION FROM OTHER LAB USERS at all times and observe the maximum

occupancy rules that are posted in each room of the lab. Please observe all rules and be

aware that:

4.4.1. Larger lab spaces (the big rooms) have sufficient space to accommodate

more that one person. Two (2) people can work inside the following rooms:

Test Room 1120, WLO2 Room 1131 and the OLED Room 1136, provided

there is only one person using each piece of equipment.

4.4.2. No more than one (1) person at a time is permitted in the Etch room

(1137A), the AJA room (1129) and the Chemical Storage Room (1130).

4.4.3. While there is only one person permitted in these rooms, a buddy system

is still in place so that no one is alone in the lab.

4.4.4. Special protective equipment for personal safety while using wet benches

may be obtained from the lab manager. Disposable face shields and aprons

will be stocked and provided on request.

4.5. Washroom Access (Room 1127)

4.5.1. Wipe outside door handle with sanitary wipe. Enter.

4.5.2. Dispose of sanitary wipe in the garbage (not in the toilet!)

4.5.3. Wash hands according to the guidelines in the “Health & Safety Guidance

During Covid-19” document from the Safety Office

4.5.4. Use a paper towel to open the exit handle.

4.5.5. Dispose of the paper towel in the refuse bin (not the toilet!).

4.5.6. Immediately don a new pair of gloves from the dispenser.

4.6. Cleanroom – Exiting

Researchers exiting the clean room will wait at the designated locations in the clean

room hallways until the previous individual exits the change room. They may then enter

to remove their clean room apparel in the designated degowning zone. The procedure for

exiting is:

8

4.6.1. Remove your Tyvek suit and replace the suit in your assigned location in

the air-shower storage closets. Carefully avoid contact with other suits already

in the closet.

4.6.2. Remove your hair cover and dispose of it in the refuse bin.

4.6.3. Remove your shoe covers as you cross the wet bench and dispose of them

in the refuse bin.

4.6.4. Follow the marked exit pathway from the degowning area, to exit the lab

through the foyer.

4.6.5. Remove the outer gloves and dispose of them in the refuse bin before

exiting the foyer.

4.6.6. After exiting the foyer, remove your underlying gloves and face mask.

Dispose of them in the refuse bin.

4.7. Traffic Patterns, Flow of Motion, and Occupancy Limits – 1st-floor Lab

This section provides detailed visual descriptions of the required flow of traffic by

users in the 1st floor facilities. The lab will also have markers and directions to reflect the

description of the traffic patterns described. They are intended as a guideline for all users,

with the expectation that lab users will follow the guidelines for their own safety and the

safety of other users. A brief description of the experiments in each lab shown in the floor

plan below is provided along with the maximum occupancy limits (OL) within each

room. Users are only allowed to occupy space where there is a designated station

(described below) in each room.

5. G2N Third Floor Laboratories Safety Addendum

This lab space contains shared experimental equipment that is accessed outside of the

cleanroom environment. The equipment in this area interface with users without the

cleanroom garments that are described above and therefore must have additional protocols

for sanitizing surfaces. Students who wish to use shared equipment must clean all surfaces

associated with the equipment with alcohol-based disinfectant before and after use. These

surfaces include tabletops, keyboards, mice, instrumentation faceplates, handles, buttons,

knobs, cables, and power cords.

5.1. Access to 3rd- floor labs access

When users enter a room, the user must indicate they are working in the room by

placing a sign showing their name and station name beside the entrance door that contains

the station. The sign must remain there even when the student leaves the room for a break.

The student can remove the sign only when they finished using the station and exit the

room.

When more than one student is in a room at the same time, they must communicate to

each other whenever one student wishes to use shared equipment or access storage in close

proximity to the other. It is expected that a student will move away so as to maintain proper

physical distancing in order to let the other student use shared equipment.

Students working on a station must clean all surfaces associated with the station using

alcohol-based disinfectant (60%-70% isopropanol or ethanol) before beginning work for

the day and when work has concluded for the day. These surfaces include tabletops,

keyboards, mice, instrumentation faceplates, handles, buttons, knobs, cables, and power

cords.

16

Students working in the lab space must use hand sanitizer immediately upon entering

and before exiting the lab. It is recommended that students wear a non-surgical face mask

(GPE) when they are working in the lab. Visible markers directing flow of motion and

designated waiting areas will be clearly marked on the floor. Entry into the lab space will

only be allowed through the 3181 entrance. Exiting the lab space will only be allowed

through the 3184 doors. Once in this lab space, entry doors for the user labs will be left

unlocked and the doors open. This arrangement will make it unnecessary for users to touch

door handles and reduce the number of common contact points.

The procedure for entering this lab space will be:

5.1.1. Entry is only permitted at the 3181 entrance.

5.1.2. A hand sanitizer station will be located inside the doors. Everyone

entering this area should use hand sanitizer, following the procedures

outlined in the “Health & Safety Guidance During Covid-19” document

from the Safety Office. See Appendix 1.

5.1.3. Face masks are now required and will be available at the entry. Don a face

mask.

5.1.4. When exiting, follow the exit markers and use the doors at the end of the

hallway (3184).

5.1.5. Passback will be disabled for people using the 3rd floor area in G2N to allow

entry and exiting at the specified locations. Arrange with Richard for

permission to use the area and to have your keys reprogrammed.

5.1.6. While doors inside the lab space will be unlocked, exceptions are in place

for the following rooms:

5.1.6.1. Room 3145A – doors to this room restrict access to a Bio2 hazard

area.

5.1.6.2. Room 3179 – this room contains X-ray hazards.

5.1.6.3. Room 3177 – this room is not accessible through doors at 3181 and

3184

5.1.7. Exiting the lab space should only be performed using your personal key

fob. DO NOT USE THE OVERRIDE FOB on the wall. This key fob is to

be used only in emergency evacuations to maintain sanitary conditions and

minimize potential virus transfer points.

5.1.8. Anyone who uses the override fob should immediately wash their hands

with sanitizer or with soap and water in accordance with the “Health &

Safety Guidance During Covid-19 document” (see Appendix 1).

5.2. Washroom Access (Room 3192)

5.2.1. Wipe outside door handle with sanitary wipe. Enter.

5.2.2. Dispose of sanitary wipe in the garbage (not in the toilet!)

5.2.3. Wash hands according to the guidelines in the the “Health & Safety

Guidance During Covid-19” document from the Safety Office

17

5.2.4. Use a paper towel to open the exit handle.

5.2.5. Dispose of the paper towel in the refuse bin (not the toilet!).

5.3. Traffic Patterns, Flow of Motion, and Occupancy Limits – 3rd Floor Labs

This section provides detailed visual descriptions of the required flow of traffic by

users in the 3rd floor facilities in Fig. 10. The lab will also have markers and directions to

reflect the description of the traffic patterns described. They are intended as a guideline

for all users, with the expectation that lab users will follow the guidelines for their own

safety and the safety of other users. A brief description of the experiments in each lab

shown in the floor plan below is provided along with the maximum occupancy limits

(OL) within each lab. Users are only allowed to occupy space where there is a designated

station (described below) in each room. In addition, the location of hand sanitizer

dispensers are provided in the floor plan.

Sanitation requirements: If the user needs to open a door to enter a lab, the door handle

should first be sanitized before touching the door handle.

Before using any experimental station, the user is required to perform a surface cleaning

(as described in Appendix 2). After finishing using the station, the user is required to

perform a surface cleaning (as described in Appendix 2).

o printer test bench

o Room 3140 – Traffic flow: Different from the other third floor rooms described in this

section, this room is an office space that contains 6 desks for graduate students and does

not contain any equipment or serve as a lab. Occupancy in this room is therefore mainly

limited to students sitting at their designated desks (numbered from 1 through 6) and traffic

flow is limited to a student walking between the door and their desk. To ensure adequate

distancing, occupancy will be limited to a maximum of two students in the room at any one

time with an additional restriction that the occupants cannot be in adjacent desks. Traffic

flow will also be limited to only one person walking between the door and their desk at any

one time. The door is normally open in this room so sanitary cleaning procedures before

and after opening the door is not required.

21

Maximum occupancy: This room has a maximum occupancy limit of 2 (OL2) with the

further restriction that no 2 adjacent desks can be occupied at the same time.

6.1. Access to G2N satellite labs

One additional room in QNC is supported by the G2N staff. This room houses

several experiments in the development of organic electronic materials and devices. This

lab space contains shared experimental equipment that is accessed outside of the cleanroom

environment. The equipment in this area interface with users without the cleanroom

garments that are described above and therefore must have additional protocols for

sanitizing surfaces. Students who wish to use shared equipment must clean all surfaces

associated with the equipment with alcohol-based disinfectant before and after use. In

addition, the room is within the QNC and will follow protocols for entering the QNC

building in order for researchers to access the lab.

Room B508 – Traffic flow: Traffic in this room is in a clockwise direction upon entry

through the door adjacent to the study area in the QNC basement. The service corridor

entry way is not to be used for entry.

HAND SANITIZING STEPS:

1. Apply 1 or 2 pumps of product to palms of dry hands.

2. Rub palms together palm to palm.

3. Rub in between and around fingers.

4. Rub the back of each hand with the palm of the other hand.

5. Rub fingertips of each hand in opposite palm.

6. Rub each thumb clasped in the opposite hand.

7. Rub hands until dry and do not use paper towels.

8. Appendix 2

Surface Decontamination

Surface Cleaning – Cleaning removes organic materials from the surface. This is because

organic substances inhibit the effectiveness of any disinfectant used. Cleaning involves:

o Wearing nitrile or other similar gloves

o Removing organic materials with a disposable towel and discard

o Using a cloth and warm soapy water to wipe down surfaces

o Allowing the surface to dry

Surface Disinfection – The three most important factors to consider when disinfecting a

surface are:

o Disinfectant efficacy against whatever you are trying to kill

o Concentration of the disinfectant is strong enough to be effective.

o Contact time is long enough to allow the disinfectant to perform its action

o Commonly used disinfectants include:

Alcohol based – contact time 2 minutes

Hydrogen peroxide – contact time 5 minutes

Bleach – contact time 5 minutes

Details of proper usage of disinfectants is available from the Safety Office document: Health &

Safety Guidance during Covid-19, which is appended to this document.

(Addendum: Provisions for G2N Access under the COVID-19 Pandemic).

I _____________________________________ have read and understood the

precautions and procedures that have been implemented to protect users of the Giga-

to-NanoElectronics Laboratory at the University of Waterloo.

As a responsible user of the G2N facility I will:

1. Refrain from entering this facility if I am ill or suspect that I have been exposed to any communicable organisms or virus.

2. Maintain appropriate social distancing (2m separation) at all times while working in the labs.

3. Observe the posted limits for the maximum number of people in any lab area. 4. Use hand sanitizer where required. 5. Wear designated protective gear, including hair cover, face mask, gloves, shoe

covers and coveralls while working inside the clean room. 6. Wear designated protective gear in all other G2N facilities. 7. Observe restrictions implemented to maximize my safety and the safety of my

coworkers. In the clean room, these restrictions include: a. Observing the 1 person only in the change room rule. b. Agreeing to schedule my clean room visits through the G2N Room and

Equipment Booking System. c. Observing time limits imposed to prevent crowding yet maximize lab

access. 8. Act all times in a manner which minimizes the risk of transfer of the Covid-19

virus to other lab users or to the lab environment. 9. Identify any areas of risk to lab personnel, and work with lab management to

identify solutions which enhance the safety of users in this facility.
