Work at Height Permit

PPE

Personal Protective Equipment (PPE) encompasses all equipment, clothing, and devices worn or used by workers to protect them from workplace hazards that cannot be fully eliminated through other control measures. In the hierarchy of controls — the universally accepted framework for managing workplace risks — PPE is positioned as the last line of defense, used only when hazards cannot be adequately controlled through elimination, substitution, engineering controls, or administrative measures. Common categories of PPE in industrial settings include head protection (hard hats), eye and face protection (safety glasses, goggles, face shields), hearing protection (earplugs, earmuffs), respiratory protection (masks, respirators, self-contained breathing apparatus), hand protection (gloves rated for specific hazards), foot protection (safety boots), fall protection (harnesses, lanyards), and specialized clothing (flame-resistant coveralls, chemical suits, high-visibility vests). The selection of appropriate PPE must be based on the specific hazards identified during the risk assessment — using the wrong type of PPE can be as dangerous as using none at all. In the permit-to-work process, required PPE is explicitly specified on the permit document based on the task risk assessment, and verification that all workers have the correct PPE is a prerequisite for work to commence. PPE must be properly fitted to each worker, regularly inspected for damage or wear, maintained according to manufacturer specifications, and replaced when it no longer provides adequate protection. Training workers in the correct use, care, and limitations of their PPE is equally important.

Rescue Plan

A rescue plan is a documented emergency response procedure that defines exactly how workers will be rescued if an incident occurs during high-risk work activities. It is a mandatory requirement for work that takes place in environments where standard evacuation procedures may be inadequate — including confined space entry, work at height, work over water, and operations in remote or isolated locations. The rescue plan must be specific to the work activity and location, not a generic document, because rescue requirements vary dramatically depending on the type of hazard, the physical environment, and the number of workers involved. A comprehensive rescue plan identifies the rescue team members and their roles, specifies the rescue equipment that must be on-site and ready for immediate use (such as harnesses, winches, breathing apparatus, and first aid supplies), defines communication protocols for activating the rescue response, details the physical access and egress routes that rescuers will use, and establishes the interface with external emergency services. Crucially, the rescue plan must be communicated to all workers before work begins — typically during the pre-task toolbox talk — and should be rehearsed or tested where practical to ensure that the rescue can actually be executed within the required timeframe. In permit-to-work systems, the rescue plan is a prerequisite for permit issuance: the permit cannot be approved until a site-specific rescue plan has been reviewed and accepted by the approving authority. Many regulatory frameworks mandate that rescue capability must be demonstrated before high-risk work commences, making the rescue plan not just a best practice but a legal requirement.
