Working-at-Heights and Fall Protection

STAC Climber Training Guidelines
This document was developed to assist the Canadian tower industry’s efforts to harmonize fall protection training requirements by identifying baseline training and retraining requirements for climbers with various levels of expertise, and by outlining a coherent training curriculum through which those requirements can be taught effectively. These guidelines offer guidance to trainers, trainees/climbers and employers that can help ensure tower climbers know how to properly protect themselves and each other when working at heights in the communications industry.

Telecommunications Rooftop Site Access, Work and Visits
The objective of this document is to raise awareness about the hazards associated with working on rooftops when accessing, installing or planning for rooftop telecommunication systems, including the steps required to mitigate those hazards and the regulations and standards that govern rooftop work.

The ultimate goal of this document is to ensure that all parties in the chain of development – from vendor to installer – recognize and understand the hazards of rooftop work, and then use that understanding to promote conversation and develop their own processes for safe work procedures.

PLEASE NOTE that this document has been temporarily removed from publication as the STAC project team works to provide an updated version of the document following the release of new federal fall protection regulations in July 2019. In particular, STAC notes that the previous version of this document listed fall hazard zones as second in the order of hierarchy of fall protection systems, whereas new federal

Worker Antenna Mount Access – Current & Best Practices
The intent of this document is to promote conversation on worker safety in regards to antenna mount structural adequacy to support workers and associated fall protection anchorage locations and strengths for workers to use.

The goal is to create conversation through pictures and current designs to ensure tower engineers are aware of the problems that exist for workers installing equipment on pinwheel mounts, and to then develop best practices or design changes to mitigate the hazards.

RF Safety

Identifying & Responding to RF Hot Zones (Best Practices and Guidelines)
This document is intended for use by workers in the Canadian communications or tower industries who work around RF antennas in the 3 kHz to 300 GHz range.

This document uses the expertise and observations of experienced workers to help define industry best practices for identifying transmission antennas and other common RF equipment, and for determining whether such equipment or equipment installations pose a potential safety hazard.

Personal RF Monitor Best Practices & Guidelines
This document is designed to provide an overview of important information that Canadian tower and communications workers should be aware of before using a personal RF monitor or working around RF emitting equipment. This document is designed to duplicate information that should be provided to all workers who intend to work around RF emitting equipment during their introductory RF training.

Tower Engineering

STAC Study – Mitigating Anchor Shaft Corrosion and Related Tower Failures
This document provides information about how corrosion affects below-grade steel anchor shafts on guyed communications towers, as well as factors that can affect corrosion rates.

The intent of this document is to provide communication tower owners and operators with a resource to help inform decisions relating to guy tower siting, anchor shaft corrosion protection and anchor shaft inspections. Notably, however, this document is not prescriptive and is not intended to provide explicit direction on how to apply protective measures or conduct inspections. Rather, this document outlines factors that companies and crews should consider when studying protection or inspection options and priorities.

Recommended Anchor Shaft Inspection Priority Matrix
This matrix is designed to assist communications tower owners assess the relative urgency of recommended anchor shaft inspections for each guyed tower in their inventory. Importantly, there may be additional considerations not accounted for in this matrix that may justify increasing the inspection priority for individual or groups of towers.

National Safety Code (NSC) Standard 10 – Cargo Securement
This document provides an overview of Canadian Council of Motor Transport Administrators (CCMTA) cargo securement regulations, as provided under National Safety Code for Motor Carriers (NSC) Standard 10. These general compliance guidelines are designed to instruct workers and companies in the transmission tower industry, and focus only on NSC regulations that are likely to affect crews in this industry.


National Safety Code (NSC) Standard 11 – Maintenance and Periodic Inspection Standards
This document provides an overview of Canadian Council of Motor Transport Administrators (CCMTA) maintenance and periodic inspection standards. These general compliance guidelines are designed to instruct workers and companies in the transmission tower industry, and focus only on NSC regulations that are likely to affect crews in this industry.

UAV Services for the Communications Tower Industry
This document was developed to help tower owners and tower contractors identify the various unmanned aerial vehicle (UAV) services that are currently available and applicable to the communications tower industry.

This document was developed in consultation with members of the STAC New & Emerging Technologies Committee, including representatives of UAV operators and suppliers: Canadian UAV Solutions Inc., Gap Wireless and inUAVi.

STAC Governance Policy
This document was developed to provide STAC with a consistent set of rules that will govern how the Council operates, including how its leadership is selected and the means through which committees, meetings and activities are run.
