Rooftop Maintenance Activitiesand Fall Protection Considerations April 2009
One small disclaimer This presentation focuses on fall hazard considerations for: • maintenance activity • on “flat” roofs
Does a fall hazard exist? • For each building, are employees working on roof protected from fall hazards? • Is roof that employees need to work on “flat”? • Parapets or railings for roof edges? • Screens around equipment • Rails or screens on skylights? • If not fully protected, assess the work locations and hazards
Inventory tasks and locations • What are the tasks and specific locations for rooftop work? • What are the travel paths for those tasks and locations?
List of tasks • Repair/maintenance of equipment • HVAC, transmission/reception, lighting, web cam, weather monitoring, other • Window cleaning (clerestory and side of building) • Gutters and drains • Moving ballast in order to repair leaks • Repairing roof leaks • Flashing work • Replacement of equipment • Roof repair • Temporary installations or tasks • web cams, video taping for commencement, other • Inspection
Travel path • Accessing roof levels • Ladders: fixed and portable • Hatches • Travel paths • Proximity to unprotected edges, skylights • Obstructions
Path of travel to roof hatch Planks over dead wall space
Fall hazard survey • Type of hazard (fall from roof deck) • Configuration of hazard (layout) • Exposure rating (high, medium, low) • Frequency and duration of job • Height of potential fall/ severity level • Suggested solution • Type of rescue equipment (if required)
Environmental factors • Electrical hazards • Unstable, uneven, slippery surfaces • Unguarded openings • Climatic and weather factors • Sharp objects and abrasive surfaces • Non-ionizing radiation • Other
Fall protection hierarchy • Elimination or substitution • Passive fall protection • Fall restraint • Fall arrest • Administrative controls
Fall protection hierarchy 1. Elimination or substitution; 2. Passive fall protection; 3. Fall restraint; 4. Fall arrest; 5. Administrative controls
Roof access and work policy • Does your policy address: • Who can access the roof • How is access controlled • Work on tasks with hazard assessment • Work on tasks without hazard assessment • Procedure for work on tasks without formal hazard assessment • Environmental conditions: night, winter, hazardous weather
‘Temporary’ installation Construction web camera, 18-24 months.
Some questions • How far from an unprotected edge or opening is high, medium, and low exposure? • At what distance to an unprotected edge or opening does someone need a fall restraint or fall arrest system? • In which situations would we use administrative controls? In which situations would we never use administrative controls?
A B Distance from edge How do you protect employees at A (2 ft from edge) and at B (20 ft from edge)?
Protected access point Note also unit in background, upper right.
Lights Are these serviced with articulating lift? Or from the roof?
Multiple considerations Low slope on loose ballast stone. Equipment on flat portion. Gutters that need cleaning.
I’ve done this hundreds of times. I know how towork near an edge.
