Fall-protection Section 2 – General Safety Precautions
2.3 Fall-protection
The guardrail system is the primary fall-protection
system of the MEWP platform.
If personal fall-protection equipment (PFPE) is
required, by an employer or the authority having
jurisdiction, Skyjack recommends the use of a full
body harness with a lanyard. PFPE must be attached
only to approved fall-protection anchorage points in
the platform.
All PFPE must be compliant with applicable
government rules and must be inspected as per the
manufacturer’s recommendation.
WARNING
Fall hazard.
▪Only enter and exit the MEWP using the three
points of contact principle.
▪Only use the equipped access openings.
▪Only enter and exit the MEWP when the
platform is fully lowered.
▪Face the MEWP when entering or exiting the
platform.
Failure to follow these instructions could result in
death or serious injury.
Enter or exit the platform from the ground only. Use
the three points of contact principle, which is when
two hands and one foot, or one hand and two feet are
in contact with the MEWP or the ground at all times.
Face the MEWP when entering or exiting the platform.
2.4 Worksite inspection
Make sure the operating environment, ambient
temperature, Electromagnetic Compatibility (EMC),
and Hazardous Location Rating (locations with
potentially flammable gases, explosive gases or
particles) are appropriate for the MEWP specifications
(refer to Section 7.4).
Be sure to follow all national, state/provincial/territorial,
and local rules that relate to operating the MEWP.
Perform a full worksite inspection before operating the
MEWP. Identify potential hazards in the area.
