1.2 MOUNTING SYSTEM
Solar modules are installed on rooftops where there is danger of personnel falling off
of the roof. Scaffolding, stepladders, and ladders may be dangerous and require
caution. The installation of solar modules involves work in high places, take extreme
precautions to avoid falling from roof. To prevent accidents, safety regulations must
be observed. Always take the following precautions to prevent accidents and injury.
1 Take the following precautions before starting work.
• Plan the job and visit the site before starting work.
• On site, do not work alone. Always work with at least one other person.
• Inspect power tools before using them.
2 When conditions make it necessary, tell workers to stop working.
• When it is raining, or there is a strong probability that it will start raining.
• Immediately after rain, and when work areas are slippery.
• When high wind conditions exist, or are expected, or when a high wind warning
has been issued.
• When it is snowing, or when there is snow underfoot.
• When the condition of the scaffolding and ladders are not satisfactory.
3 Wear appropriate work clothes and protective equipment.
• Work clothes for both the upper and lower body should fit well and allow you to
move freely.
• Always wear protective equipment such as harnesses and lifelines.
• Wear a helmet and secure it correctly.
• Wear non-slip shoes. Shoes get dirty when worn on a roof, so keep the soles clean.
4 Observe safety regulations for ascending and descending ladders and
stepladders.
• Before use, always inspect ladders and stepladders to makes sure they are in good
condition.
• Choose a safe spot to anchor ladders and stepladders.
• Always work with a partner. One person should hold the ladder steady.
• Ladders from a first-story roof to a second-story roof are very dangerous. Do not
set up a ladder on a roof. When there is no other choice, straddle the ridge and lay
down a rubber anchor mat, and secure the ladder to the mat. Always have one
person hold the ladder firmly.
• When you use a two-stage ladder, secure it with ropes or stays to prevent it from
sliding sideways, and have two persons hold the ladder steady.
