Safety is Pasquill’s number one priority, for both employees and customers and therefore we have produced a number of documents to help you improve safety on site, highlighting how to safely unload, store and install your roof trusses.

Unloading your Roof Trusses

It is your responsibility for providing the following:

  • The right number of able bodies for the unloading of materials, with the right skills
  • Barrier tape
  • The necessary mechanical handling equipment – i.e. a crane or forklift
  • A timber bearer (required for inverted trusses)
  • Personal Protective Equipment (PPE) – hard hat, safety footwear, safety gloves, high visibility outerwear

 

Roof Trusses are generally delivered in tight bundles using bindings; your trussed rafters (also known as roof trusses) must be unloaded safely following the correct procedures, so it does not overstress the trusses.

In most circumstance mechanical handling equipment, such as a forklift or a crane, is required to unload your trusses on site. It is your responsibility to ensure you have the correct mechanical handling equipment and labour on site when the trusses are delivered.

Mechanical handling equipment avoids the need for anyone to access the bed of the lorry, thus removing the risk of an injury. To assist contractors on site Pasquill use different coloured bandings or restraints to reduce the risk of the incorrect band or rope being cut.

We have a number of Safe Unloading documents to assist you when unloading your trusses on site. View the documents below or take a look at more in our Technical Library.

Storing your Roof Trusses

The delivery of your roof trusses should be arranged closer to the time of installation to reduce on site storage time. However, if your roof trusses are not to be installed immediately after the delivery to site, it is important to think about, prior to the delivery, how and where your trusses are going to be stored.

Roof trusses can be stored safely in a vertical or horizontal position at ground level, or on an appropriately designed storage platform, above ground level. The trusses must not make direct contact with the ground or any vegetation, with either method you have used. Your trusses need to be arranged to avoid distortion and secured to prevent the trusses collapsing. They should be protected from the elements and should not be left in an area which is damp or near water.

If the trusses are stored vertically, bearers should be positioned appropriately to provide a more firm and safe support. Alternatively, if you decide to store them horizontally, to prevent any distortion, level bearers should be positioned between each truss node. Covers should be used to protect your trusses and fixes to allow for proper ventilation.

Installing your Roof Trusses

Installing your roof trusses should only be carried out by suitably trained and qualified personnel (such as those with a Level 2 Diploma in Site Carpentry). Furthermore, a full site-specific risk assessment must be completed before installation begins.

See below the steps in which you should take prior to installing the trusses.

  • Read and check all the assembly drawings and information provided
  • Ensure all PPE is worn
  • The scaffolding is in place and has been signed off to use
  • A safe working platform within the structure
  • Hop-ups and the scaffolding edge protection are in place
  • Once reading the layout drawings identify the easiest starting point using the simplest roof of trusses

Take a look at our guide ‘How to Safely Install Roof Trusses’ for a step-by-step guide to the safe installation of your trusses. Here you can find a more in depth guide to the steps below.
