Stageline Mobile Stage Inc. designed its stages to meet or exceed applicable requirements as descri-
bed in the current building codes and their supplements. The nature of the structures manufactured by
Stageline requires that environmental loads considered for the designs are reduced using the provisions
contained in ANSI E1.21 2013. Thus, for safety concerns, specific procedures need to be applied by
trained personnel (refer to official Stageline documents for details) depending on current and forecasted
weather conditions.
During winter in regions where snow and ice accumulations are possible, the weather can be hard to predict to an acceptable degree of
precision. To guarantee a safe use of Stageline mobile stages during this season, special measures described herein are mandatory and
pertain to standard safety procedures.
The following restrictions apply:
1. If installed over a snow covered surface, a certified technician must remain on site at all times while the stage is open. If the
technician needs to leave the site for more than 2 hours, the stage must be closed.
2. During use of the stage, monitor regularly (minimum every 2 hours) and check for abnormalities such as sinking, slippage on the
ground or snow/ice formations on the structure.
3. Overall structure resistance is calculated at 20 psf. Snow can weigh as much as 10 psf for every 1 foot of accumulation. It is
therefore recommended to remove snow or ice from the roof before it builds-up; thicker than 6 inches of snow, or 1 inch of ice.
During wintertime, to account for loads generated by precipitations as described above, rigging capacity of the roof should
therefore be used at 50% of its normal capacity.
