When are Roof Anchors and Davits Required for Window Washing?

Permanent roof anchors and window washing davits are two different types of permanent window washing equipment. Which one is installed depends on what criteria the building’s architecture needs.Permanent roof anchors are usually considered for window washing on any building that’s over three storeys high.

Why Are Horizontal Lifelines Important for Fall Protection?

Horizontal Lifelines (HLL’s) are our solutions to providing a complete fall restraint system without sacrificing mobility. When a worker is within 1.8m of a vertical drop – we call this a ‘fall hazard zone or restricted area’ – they are required by law to be tied off to an anchor point (OSHA 1926.502 and ANSI/IWCA 1-14.1). However, single point anchors …

bosun's chair system (Rope Descent System) used for window washing

Guide to Bosun’s Chair Systems (Rope Descent System)

Window Washing is often performed with either a bosun’s chair system (boatswain chair system) or suspended platform in conjunction with Pro-Bel rigging equipment (such as anchors, davits, outriggers, etc.). In OSHA, a bosun’s chair system is referred to as a Rope Descent System (RDS). Read on for a quick RDS guide as outlined in OSHA 1910.27 (Scaffolds and rope descent …

Roof Rigging – Launching a Platform Explained

Roof Rigged Davit Systems are designed for buildings where ground rigging is not ideal. Sometimes, site conditions, particularly at lower levels, do not allow for a platform to be picked up from the ground. Roof conditions such as permanent equipment, parapet/screen wall height, building shape, and especially suspension height must all be taken into consideration when deciding between designing for …

Fall Arrest vs. Fall Restraint “Fall protection” is actually a term that encompasses the method of either “fall arrest” or “fall restraint”. Fall arrest prevents a person from reaching the ground (once a fall …
