Introduction
While cannabis has been fully legalized in Canada and in many states in the US, it is a new and emerging
industry that is moving at a very fast pace in many other parts of the world. While legalization is being
deliberated by governments and legislative bodies, companies are creating their own infrastructure
in anticipation of legal approval. Meanwhile, government regulators and the societies they serve are
grappling with the lack of consistent rules and guidance to deliver safety, security and sustainability
of cannabis facilities and operations, while growers and producers use their own judgment on how to
establish and operate facilities.
It has become very clear that the global cannabis market is opening up very rapidly. The cannabis
product and the industry will become more and more ubiquitous as the global barriers start to lower
and come down. If the current trend continues, it is predicted that well over one third of the globe will
accommodate cannabis by 2024.
What is unique about this new and emerging industry is that it is coming from an illicit status into
decriminalization and evolving into a legitimate burgeoning business. Due to its pioneering status, very
little exists in terms of research, studies, historical experience and best practices. Standardization is
likewise very slow on the uptake and the cannabis industry remains severely underserved.
There are therefore distinct challenges for the safety, security and sustainability of cannabis facilities
and operations, which the IWA 37 series seeks to address as follows:
— Part 1 (this document): Requirements for the safety of cannabis buildings, equipment and oil
extraction operations;
— Part 2: Requirements for the secure handling of cannabis and cannabis products;
— Part 3: Good production practices (GPP).
In addition to the requirements for sites, facilities, buildings, and equipment specified in this document,
statutory and regulatory requirements and codes can apply.
NOTE Annex A provides information on international construction codes to consider when working with
this document.
Supporting material to accompany the IWA 37 series is available at the following website:

International Workshop Agreement IWA 37-1:2022(E)
Safety, security and sustainability of cannabis facilities and
operations —
Part 1:
Requirements for the safety of cannabis buildings,
equipment and oil extraction operations
1 Scope
This document specifies a minimum level of protection and safety for buildings or parts thereof,
which are used for the commercial cultivation, specific to processing of cannabis plants and cannabis
products, and ancillary activities associated with cannabis plants and cannabis products.
This document specifies a minimum level of safety for the installation of devices, equipment, and
systems used for cannabis cultivation, processing, and ancillary activities and addresses the risks
of fire, electric shock, injury to persons, and explosion associated with these devices, equipment and
systems.
This document includes minimum considerations for training of personnel and equipment maintenance.
This document specifies direction for the safe methods of extracting oil from cannabis plants, including
but not limited to, initial extraction and post-processing refinement.
Where buildings or premises combine cultivation and processing of cannabis plants, including ancillary
activities along with other operational activities, the requirements of this document are intended to
apply to only that portion of the facility.
NOTE In many cases, a building or facility can be used for both the cultivation of cannabis plants and
processing of cannabis products, along with a retail store front, call centre, or office administration space. Where
such joint use activities are present in a common building, it is possible that local building or fire codes can
require the installation or extension of certain life safety systems, such as fire alarm and fire sprinklers.
This document does not address the following:
— general building construction features that are normally a function of applicable codes;
— premises used exclusively for operational activities such as office space, call centres, and retail
outlets, used for the distribution, marketing, or sale of cannabis;
— any use of the cannabis plant or cannabis products;
— the physiological or other attributes or effects that can result from the use of this equipment;
— the transportation of cannabis or cannabis related products;
— occupational health and safety requirements governing cannabis workers and personnel except as
specifically identified in this document;
— security of the supply chain monitoring system, including cybersecurity and notifications;
— outdoor grow area (including cannabis and industrial hemp).
NOTE 1 Shipping and receiving of products from the production facility for further distribution are not
considered as a retail outlet.

NOTE 2 This document is not intended to apply to facilities that are used exclusively for operational activities
such as selling, marketing, or other business administrative purposes. This can include but not be limited to,
retail rental space, call centres, or other facilities that are not combined with cultivation and ancillary activities
associated with the growing, processing, and storage of cannabis plants and cannabis products.
All requirements in this document are generic and intended to be applicable to all organizations in the
cannabis supply chain, regardless of size and/or complexity.
