Most experienced professionals will tell you it’s always best to plow with the storm. The deeper the snow, the harder the job. Deep snow also decreases your productivity. If you expect snow accumulation of greater than one inch, you should plan on plowing.
When we think of “safety” with regards to snow removal, there are some significant considerations that have to be taken into account. The timing of the work that is required comes into play. The vast majority of work done in winter snow removal operations is done at night. This presents some challenges that don’t normally incur during landscape operations. Additionally, a good portion of the work is done “behind the wheel”, and this too is different than most landscape/tree care/irrigation/excavation work.
