AFETY
23-
Contact the distributor/service center or Hydro Mobile for service, repair or technical
advice. Refer to equipment type and serial number when calling.
24-
Each person should access the platform by a staircase, through an opening in the
building or, when the unit is at least 10' (3 m) above base level, by the
back
of the mast,
using the access walkway to reach the platform. The use of the access walkway is
mandatory
to reach the platform by the mast. To avoid crushing hazards, it is important
to make sure that the access ladder is
fully extended
before it is used. In all cases,
transfer must be safe and free from obstruction.
25-
The use of appropriate fall protection equipment is
mandatory
when using the mast for
climbing or descending at heights between 30' (9,1 m) and 69' (21 m), when modifying
plank
confi guration or whenever the worker is exposed to a fall hazard. Failure to use fall
protection equipment can expose the user to serious injury or death. It is not recommended
to climb up the mast to reach work areas at heights over 69' (21 m) because of the time
and effort required to reach such heights. The use of alternate equipment compliant with
local regulations, such as a rapid mast climber, a transport platform system, or a
conventional scaffold stair system will prove to be more effi cient. Refer to local regulations
for more information.
26-
Only one person at a time may evacuate the platform by climbing down the mast. It is
not recommended to evacuate the platform by climbing down the mast when the platform
is at heights beyond 69' (21 m).
27-
In the event of an abnormal occurrence or operation which could compromise security
(ex. malfunction of a motorized unit component, collision with an obstacle, etc.), immobilize
the unit and inform the competent person.
28-
It is strongly recommended not to touch any of the moving parts on the motorized unit
when it is in use.
29-
All access doors and panels on the motorized unit must be closed when they are not in
use. All access doors and panels should be free from any material or obstruction.
30-
The motorized unit must not be used or operated during an electrical thunderstorm.
31-
The deposit of loads on the setup must be done with extreme care and under proper supervision.
Refer to the
Load Capacities
section on p. 80 for more information about placing loads on the
platform. When the motorized unit setup is not in use and
above base level
, loads must not
be left on the platform except for counterweights.
Performance and Safety Rules
General guidelines (cont’d)
Defi nition of a standard installation
A
standard installation
, referred to throughout this owner’s manual and related documentation, is an
installation that
does not require
the use of additional equipment, such as a forward extension bridge,
a swivel bridge or a planking confi guration wider than four planks nor the use of accessories such as
weather protection, a hoist or a monorail.
It is
mandatory
to refer to the
Load Capacities
section on p. 80 for the number of bridges allowed in
a standard single unit or multiple units installation.
WARNING - WIND SPEEDS
The
erection
and
dismantling
of a motorized unit setup (including the base, the bridges,
the masts, the mast ties and all the other components) must not be conducted when wind
speeds exceed
28 mph (45 km/h)
.
Freestanding installations
and
setups equipped
with weather protection
, when allowed, must not be used with wind speeds exceeding
28 mph (45 km/h)
.
Weather protection
, when allowed,
must not be used
when work is
performed on an
open air structure
. A motorized unit setup with
mast ties must not be
operated
when wind speeds exceed
35 mph (56 km/h)
.
When a motorized unit is not in use
- It is mandatory to leave the platform between two tie levels when the motorized unit
is not in use.
- Remove all loads from the setup when the motorized unit is not in use.
- It is mandatory to leave all the counterweights applied on the setup in place when the
motorized unit is not in use.
- In a freestanding installation, when allowed, the motorized unit must be brought down to
base level when not in use.
-
If wind speeds are expected to exceed
94 mph (150 km/h)
, the motorized unit must be
brought down to base level when not in use.
