WHAT IS A CODE OF PRACTICE? WSCC codes of practice provide practical guidance to achieve the safety requirements of the

Northwest Territories and Nunavut Safety Acts and related Regulations.

As per subsection 18(3) of the Northwest Territories and Nunavut Safety Acts, “For the purpose

of providing practical guidance with respect to the requirements of any provision of this Act or

the regulations, the Chief Safety Officer may approve and issue such codes of practice as he or

she considers are suitable for that purpose.”

WSCC codes of practice apply to workplaces in the Northwest Territories and Nunavut. The Chief

Safety Officer approves codes of practice for use by all occupational health and safety (OHS)

stakeholders. Codes of practice come into effect in each territory on the day they are published

in the Northwest Territories Gazette and Nunavut Gazette.

Codes of practice do not have the same legal force as the Safety Acts and related regulations. A

person or employer cannot face prosecution for failing to comply with a code of practice.

However, in legal proceedings under the Safety Acts and related Regulations, failure to observe

a code of practice may be a consideration when determining whether a worker or employer

complies with the Safety Acts and related Regulations.

Employers and workers should follow WSCC codes of practice unless there is an alternative

course of action that achieves the same or better occupational health and safety outcomes.

Provides practical guidelines.

Adapts to individual work sites.

May serve as evidence.

Should be followed unless there’s a better way.


INTRODUCTION This code of practice provides basic guidelines to ensure worker safety in the workplace through

the use of personal protective equipment (PPE). The code provides information on the

regulatory requirement of standards related to commercial diving operations.

Definition

Personal Protective Equipment means any clothing, device or other article that is intended to be worn or used by a worker to prevent injury or to facilitate rescue.

Diving work involves underwater construction, engineering, inspection, maintenance, repair,

cleaning, salvage, search and rescue, and archaeological and marine research.

The main occupational hazards affecting diving include:

Working under overpressure

Set up of dive locations

Environmental conditions

o Poor visibility

o Cold temperatures

o Water current

Safety of equipment

Exposure to hazardous substances

Biological agents in polluted water

Excessive physical loads

Working hours and rest periods

The use of PPE does not prevent accidents or eliminate hazards. Make every effort to control all

hazards at the source and take appropriate measures to reduce the risk to divers.


REGULATORY REQUIREMENTS The Occupational Health and Safety Regulations identify when to use PPE.

This code provides information on standards from the Canadian Standards Association (CSA). It

is important be familiar with your requirements under the regulations and review the most up

to date applicable CSA standard for specific details about best practice in PPE use.

CSA STANDARDS The Canadian Standards Association develops standards to address needs such as

enhancing health and safety. To view CSA standards online see https://ohsviewaccess.csa.ca/

CSA Group test and certify products to Canadian standards and issue the CSA mark for qualified

products.

UNDERSTANDING CSA CODING

CAN/CSA Stands for Canada and the Canadian Standards Association.

Z259.1 Lettering between CAN/CSA and the last two digits represent the internal

CSA coding of the relevant standard.

-95 The last two digits indicate the year issued.

Technological and research developments result in regular updates to standards. The end of the

CSA reference changes to the year of the update.

The current edition of the occupational safety code for diving operations is CAN/CSA-Z275.2-

F11. This shows that it was amended in 2011. This is the standard that applies to the regulation.

The current edition of CAN/CSA-Z275.4-12 is called the Competency Standard for diving,

hyperbaric chamber, and remotely operated vehicle operations. It supersedes the previous

editions published in 2002 and 1997 under the title Competency Standard for Diving Operations.

The 2012 edition is the standard that applies to the regulation.

MAKE SURE YOU USE THE MOST UP-TO-DATE STANDARD.

https://community.csagroup.org/login.jspa?referer=%252Findex.jspa


1. CAN/CSA-Z275.2-11

The CSA Z275.2, Occupational safety code for diving operations is part of a series of Standards

on diving and caisson systems covering hyperbaric facilities, occupational diving, and

construction work in compressed air.

This Standard addresses equipment requirements for the following diving systems:

SCUBA Diving Systems

Surface-Supply Diving Systems

Deep-Diving Systems

Diving in Contaminated Environments

2. CAN/CSA-Z275.4-12

The CSA Z275.4, Competency Standard for diving, hyperbaric chamber, and remotely operated

vehicle operations supersedes the previous editions published under the title Competency

Standard for Diving Operations.

This Standard applies to occupational diving, hyperbaric facility, and remotely operated vehicle

(ROV) operations conducted in connection with all types of work and employment. The

Standard describes the requirements for minimum competency levels for all personnel directly

associated with the identified techniques of diving or ROV operations.

This Standard addresses competency requirements for the following types of diving:

Occupational (Open-Circuit) SCUBA Diving

Surface-Supplied Diving

o Air:

Restricted Surface-Supplied

Unrestricted Surface-Supplied

o Mixed Gas

Deep Diving

include work techniques associated with underwater diving operations.

include special competency requirements for unexploded explosive ordnance (UXO) diving

operations (see CSA Z275.6 for such requirements).

apply to scientific diving as defined in the Standard (refer to CAUS's Standard of Practice for
