Under the Occupational Safety and Health Act of 1970, employers are responsible for providing a safe and healthful workplace for their employees. Cleaning up after a storm encompasses a variety of tasks, each of which can carry risks if performed incorrectly or without proper safeguards, according to the Occupational Safety and Health Administration (OSHA).

Common hazards include:

• Electric shock from contact with downed power lines or the use of ungrounded electrical equipment;
• Falls from snow removal on roofs or while working in aerial lifts or on ladders;
• Being struck or crushed by trees, branches or structures that collapse under the weight of accumulated snow;
• Carbon monoxide poisoning from gasoline-powered generators in inadequately ventilated areas or idling vehicles;
• Lacerations or amputations from unguarded or improperly operated chain saws and power tools, and improperly attempting to clear jams in snow blowers;
• Slips or falls on icy or snow-covered walking surfaces;
• Being struck by motor vehicles while working in roadways; and
• Hypothermia or frostbite from exposure to cold temperatures.

OSHA offers these tips for addressing these hazards:

• Assume all power lines are energized, keeping your distance and coordinating with the utility.
• Make certain that all electrically powered equipment is grounded.
• Provide and ensure the use of effective fall protection.
• Properly use and maintain ladders.
• Use caution around surfaces weighted down by large amounts of snow.
• Be sure all powered equipment is properly guarded and disconnected from power sources before cleaning or performing maintenance.
• Use and wear eye, face and body protection.
• Clear walking surfaces of snow and ice, and use salt or equivalent where appropriate.
• Establish and clearly mark work zones.
• Wear reflective clothing.
• Use engineering controls, personal protective equipment, and safe work practices to reduce the length and severity of exposure to the cold.
