Sequence of Basic Job Steps / Potential Hazards / Safe Job Procedures
Access the roof to setup the proper tools and equipment needed to install the exhaust fan. Look closely for all fall exposures. Roofs may be accessed by roof hatch openings, extension ladders placed outside against the building, fixed ladders on exterior walls, aerial boom lifts. 100% fall protection is required at all times. / ·  Inadequate fall protection, potential for a fall from the roof. 100% fall protection at all times.
·  Asbestos roofing materials.
·  Roof vents emitting chemical or flammable vapors, etc. / ·  Determine the adequacy of the walking/working surface where the exhaust fan will be located. Use personal fall arrest equipment and life lines when working within 6 feet of any uncovered roof openings. Install fall protection warning line system barrier no closer than 6 feet from roof edges, and provide a safety monitor while working in close proximity to established warning line system barriers.
·  Obtain evaluation or information on roofing materials prior to any work.
·  Evaluate work place prior to any work.
Ensure that the Crane Contractor properly sets up the crane to safely lift the exhaust fan to the roof location. / ·  Severe weather, high wind, unexpected wind gust, overhead electrical power lines that could cause a crane tipover, leading to potential significant injury to personnel. / ·  Establish a severe weather plan that monitors the weather and establishes actions to take upon severe weather approaching.
·  Review the Crane Inspection Documentation and Crane Operator Training Records from the Crane Contractor.
Sequence of Basic Job Steps / Potential Hazards / Safe Job Procedures
Lift the exhaust fan to the roof with the crane and position into proper location. / ·  Unsafe operation of crane can lead to potential personnel injury, property damage, or death from being struck by the crane.
·  Personnel landing the fan on the roof could fall through the roof hole if proper fall protection is not worn.
·  Improper body posture can lead to back injury. / ·  No one should ever be underneath suspended loads. Ensure proper crane lifting procedures are followed.
·  Personnel cutting the roof hole or landing the fan on the roof must wear personal fall arrest system to prevent them from accidentally falling through the roof hole.
·  Proper employee lifting procedures – proper body mechanics or the use of mechanical assistance to reduce strain.
Install proper ductwork. / ·  Improper use of sharp hand tools can lead to injury. / ·  Wear gloves and suitable eye protection when cutting joints apart.
·  Use caution with tools.
Conduct welding, brazing to install electrical copper wires. / ·  Fire hazard due to hot work, can lead to potential fires and/or explosions. / ·  Initiate proper hot work permit which includes fire extinguisher and fire watch.
·  Evaluate all MSDS sheets for all materials being heated. Is lead paint in the area? Ensure respiratory protection is available if needed.
Test the operation of the exhaust fan to ensure effective operation. / ·  Improper electrical safety practices can lead to employee electrical burn or other injury. / ·  Conduct proper electrical safety practices, following Lockout/Tagout procedures, high voltage work procedures, or energized circuit work procedures. Wear appropriate PPE and consider arc flash hazards.
Properly clean the work area when project is complete. / ·  Poor housekeeping can lead to slip, trip or fall. Materials could be blown off the roof! Poor housekeeping could also cause roof leaks on rubber membrane roofing layers. / ·  Perform proper housekeeping practices.
·  Discard materials in a safe way.
