OSHA has investigated 16 such serious injuries or deaths in the past 10 years, all of which could have been prevented.
“Often workers climb directly onto the roofs or structures and use equipment such as shovels, snow rakes, snow blowers and ladders to access roofs and apply de-icing materials,” said Rick Rabin, a technical assistance and training associate at MassCOSH. “Workers who perform these activities have little experience or training on the hazards they may encounter. It is incumbent upon the employer to evaluate the hazards and provide the necessary training before workers begin the work.”
Based on findings of OSHA worksite investigations, falls cause the most worker fatalities and injuries during rooftop snow removal. Workers may fall off roof edges, through skylights, and from ladders and aerial lifts. Workers also may be injured or killed by a roof collapse.
In order to prevent worker injury when removing snow from roofs, OSHA requires employers to take the following precautions:
-
Use snow removal methods that do not involve workers going onto roofs, when possible.
-
Provide fall protection equipment to workers who go onto roofs.
-
Guard skylights so workers do not fall through.
-
Mark skylights, roof drains, vents that might be hidden by the snow.
-
Avoid contact with electrical power lines. Keep ladders, aerial lifts and workers at least 10 feet away from power lines.
-
Evaluate weight load exerted on the roof to ensure it can hold the snow plus workers and equipment. Do not pile snow on roof.
-
Train workers to recognize fall hazards, use fall protection harnesses and anchor points correctly, use aerial lifts safely, use ladders safely and avoid electrical power lines.
-
Protect people on the ground from snow and ice falling off the roof during removal operations.
