One small disclaimer

This presentation focuses on fall hazard considerations for:

  • maintenance activity

  • on “flat” roofs


Does a fall hazard exist l.jpg
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 l.jpg
Inventory tasks and locations

  • What are the tasks and specific locations for rooftop work?

  • What are the travel paths for those tasks and locations?

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)

  • Climatic and weather factors

  • Sharp objects and abrasive surfaces

  • Non-ionizing radiation

  • Other

1. Elimination or substitution;

2. Passive fall protection;

3. Fall restraint;

4. Fall arrest;

5. Administrative controls



Roof access and work policy l.jpg
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 l.jpg
‘Temporary’ installation

Construction web camera, 18-24 months.


Some questions l.jpg
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?




Distance from edge l.jpg

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 l.jpg
Protected access point

Note also unit in background, upper right.




Lights l.jpg
Lights

Are these serviced with articulating lift? Or from the roof?


Multiple considerations l.jpg
