  roof process are
• Fall Hazards (From the rooftop inside the attic
  area and from ladders.
• Crushing Hazards (From the tilt-up roof
  collapsing on the workers).

• Employee rides the roof (the live load) up as he
  signals the crane operator.

Accessing the Attic Area

Accessing Attic Area Hazards

Once the roof is tilted up the employee climbs
down from roof into the attic with no fall
protection.

Tilting Up the Roof Ridge Hazards

• Some modular roof designs have an additional
  hinged roof section that connects the roof ridge.
  
• These employees are exposed to fall hazards while
  tilting this final section into place.

11
Securing Roof Supports Hazards

• This employee along with other co-workers are
  lifting the roof up onto the support posts.
• These employees are pulling the roof supports
  into place.
• Both groups are exposed to fall hazards.

Safe Alternative Portable Horizontal Lifeline

• This horizontal lifeline system is designed to be
  attached to 2x4s on residential construction
  sites and could be installed within the attic of
  a module home to be tied off to during the tilt
  up process.

15
Safe Alternative Disposable Anchor Points
16
Safe Alternative Permanent Anchor Points

• These anchor points could be installed on the
  roof peak and / or on top off the ceiling joists
  in the attic area for use during tilt-up roof
  procedures.

17
Safe Alternative Rope Grab (Vertical lifeline)

• Once the tilt-up roof work moves to the roof
  slope, a rope grab could be installed to a roof
  peak anchor.

18
Safe Alternative Rope Grab with a Horizontal
Lifeline

• This rope grab is used in conjunction with a roof
  top horizontal lifeline that also allows the
  worker to move side to side on the roof as well
  as up and down.

19
Safe Alternative Proper Use of Personal Fall
Arrest Equipment

• Once the anchor points are in place the employee
  must properly wear a full body harness and
  connect to the anchor point with a proper
  connecting device
• The connecting device could be a shock absorbing
  lanyard, a retractable lifeline or a rope grab
  device.

20
Crushing Hazards

• During this installation 2 individuals were
  standing under the roof which was being suspended
  by a crane.
• The failure of the crane, the hoist line, or the
  rigging could have crushed the 2 workers.

21
Crushing Hazards

• This installation involved a crew of 5 that were
  standing under of roof suspended by a crane.
• Again, a failure of the crane, hoist line, or
  rigging would have resulted in the roof crushing
  these 5 workers.

22
Roof Jacks Crushing Hazard Safe Alternative

• These devices can be put in place prior to
  hoisting the home.
• In this scenario, the employee would still need
  to access the attic area but could hoist the
  tilted roof without going under the roof.

23
Roof Jacks Crushing Hazard Safe Alternative

• The roof jacks are able to jack the tilted roof
  into place from the ground below on single story
  installations.
• This eliminates the need to climb into the attic
  area reducing the crushing and fall hazards.
