Background information:
Where to lift?
Reduce
force
required
by lifting
far from
hinge

Where’s the hinge?
![Page 5: Safety Tips for Opening catch basin lids - York University · Lid accidentally drops AFTER lift Pelham, ON (2012) One worker lifted the lid of a catch basin with a pickaxe so another](https://reader033.vdocument.in/reader033/viewer/2022051602/5aed84567f8b9a585f9052a2/html5/thumbnails/5.jpg)
Hinge side
![Page 6: Safety Tips for Opening catch basin lids - York University · Lid accidentally drops AFTER lift Pelham, ON (2012) One worker lifted the lid of a catch basin with a pickaxe so another](https://reader033.vdocument.in/reader033/viewer/2022051602/5aed84567f8b9a585f9052a2/html5/thumbnails/6.jpg)
Lift far from hinge
• Insert tool into lid as far
as possible from hinge
• Handle pointing away
from hinge
• Hands as far away from
hinge as possible
![Page 7: Safety Tips for Opening catch basin lids - York University · Lid accidentally drops AFTER lift Pelham, ON (2012) One worker lifted the lid of a catch basin with a pickaxe so another](https://reader033.vdocument.in/reader033/viewer/2022051602/5aed84567f8b9a585f9052a2/html5/thumbnails/7.jpg)
Problem?
Tool inserted too close to hinge
Handle NOT pointing away from hinge
hinge
![Page 8: Safety Tips for Opening catch basin lids - York University · Lid accidentally drops AFTER lift Pelham, ON (2012) One worker lifted the lid of a catch basin with a pickaxe so another](https://reader033.vdocument.in/reader033/viewer/2022051602/5aed84567f8b9a585f9052a2/html5/thumbnails/8.jpg)
Problem?
• Obstruction on non-hinge
side
• Not possible to have tool
inserted far from hinge
with handle pointing away
from hinge
• Ask supervisor for
assistance
• How would we lift it?
• 2 people?
• Skid steer?
• Further research required hinge

Sideways lift or forward lift?
![Page 10: Safety Tips for Opening catch basin lids - York University · Lid accidentally drops AFTER lift Pelham, ON (2012) One worker lifted the lid of a catch basin with a pickaxe so another](https://reader033.vdocument.in/reader033/viewer/2022051602/5aed84567f8b9a585f9052a2/html5/thumbnails/10.jpg)
Sideways lift or forward lift?
• There may not be a single
correct way
• May be subject to individual
preference
• Forward lift
•Hands closer to spine
•Less twisting
• Further research required
![Page 11: Safety Tips for Opening catch basin lids - York University · Lid accidentally drops AFTER lift Pelham, ON (2012) One worker lifted the lid of a catch basin with a pickaxe so another](https://reader033.vdocument.in/reader033/viewer/2022051602/5aed84567f8b9a585f9052a2/html5/thumbnails/11.jpg)
1 or 2 hand lift?
![Page 12: Safety Tips for Opening catch basin lids - York University · Lid accidentally drops AFTER lift Pelham, ON (2012) One worker lifted the lid of a catch basin with a pickaxe so another](https://reader033.vdocument.in/reader033/viewer/2022051602/5aed84567f8b9a585f9052a2/html5/thumbnails/12.jpg)
1 or 2 hands?
• There may not be a
single correct way
• May be subject to
individual preference

Lid accidentally drops AFTER lift
Pelham, ON (2012)

with a pickaxe so another worker could
apply tape to the basin.
While the second worker's hand was in the
basin, the lid slipped from the pickaxe and
crushed that worker's hand.

Manhole cover lifters (rejected)
• In general, the manhole cover lifters we tested didn’t
work well with catch basin lids
• Lever style lifters are designed for lifting one end of
the cover, then sliding it along the ground
![Page 32: Safety Tips for Opening catch basin lids - York University · Lid accidentally drops AFTER lift Pelham, ON (2012) One worker lifted the lid of a catch basin with a pickaxe so another](https://reader033.vdocument.in/reader033/viewer/2022051602/5aed84567f8b9a585f9052a2/html5/thumbnails/32.jpg)
Manhole cover lifters (rejected)
Magnet style lifters would lift the
cover vertically and roll it away
• This would tend to lift the
catch basin lid off of its hinge
• Even with the manhole
covers, rolling the cover away
was difficult when there was a
slope or rough terrain (e.g.
grass)

Manhole cover lifters (rejected)
Manhole cover hooks
don’t allow the hands to
get as far away from the
hinge as the pickaxe does
