Consulting / Site Assessment / Safety Audit

It is very easy for people to ignore or not identify the potential safety hazards that surround them on a rooftop when working on the roof is not a part of their everyday routine.  Statistics show that falls from heights are a leading cause of fatalities in the workplace.

GRASP Safety Services provides consulting & site assessments to identify these hazards and present a detailed report of our findings along with recommendations on how to eliminate these hazards.  Safety in the work place should be a main focus, and the rooftop should not be overlooked.

Below are potential areas where/when most roof top hazards exist within hazard of fall distance (3m) of roof edge:

·         Access point (roof hatch, or door entrance) to rooftop located right at roof edge

·         Maintenance & Repair of HVAC equipment, or security cameras

·         Clearing of roof drains

·         Snow & Ice removal

Engineered Drawings

All safety anchoring & horizontal lifeline (HLL) systems are required to be engineer approved. As such, all systems are required to have an approved drawing that has been stamped, signed, and dated by an engineer.  All engineered drawings must contain the following contents to make it compliant with CSA Z91-02 and M.O.L. guidelines with respect to window cleaning. 

“As a minimum, the sketch should include, but not be limited to:

• a plan view showing essential structural members, including anchors and approach anchors
• details of the equipment and its installation
• the safe working loads of the equipment and any use restriction on the equipment
• all relevant obstruction and structures or other obstacles that impede the safe use or operation, or both, of the equipment
• the distance between anchors
• the location of all windows
• details of anchor system including, capacity, size and material used for every component
• related codes and standards used in designing the anchor system
• drawings that are signed and sealed by a professional engineer – clause 8 of CAN/CSA Z91-02”

Engineer Load Testing

As per CSA Z91-02 all roof anchors are to be load tested by a professional engineer prior to first use.  As well, all anchors that have been fastened by adhesive chemicals must be re-tested every five (5) years or sooner.  A record of this testing is to be kept onsite where the anchoring system is located in either the initial installation log book, or the annual anchor inspection log book.

Annual Inspections

All roof anchor systems are to be inspected by a competent person once within every twelve (12) month period.  This inspection is to check for visual damage or disruptions found within the system, and are to be recorded and available on site for all workers needing to perform any work/visit to roof top areas.  Within the report there are specific requirements that are to be met according to the CSA codes.

As per CSA Z91-02,

“The inspection shall include, but not be limited to,

(a)   a review of the design drawings to ensure compliance with current regulations, standards, and engineering standards,

(b)   an assessment of the system to ensure compliance with engineered drawings;

(c)   an inspection of all exposed, visible, and accessible components of the system for signs of distress; and

(d)   an inspection of all adhesive and expansion fasteners.”

GRASP’s inspection reports not only clearly outline any issues (or potential issues) with your existing anchoring system, it also provides options for the best way to rectify these issues to ensure compliance with the governing codes and guidelines.
