Intent 1:
To limit the probability that:
- inappropriate materials for ladders will lead to:
- inadequate strength to support expected loads, or
- an inability to resist exposure to the environment,
which could lead to corrosion, or
- the inappropriate construction of ladders will lead
to inadequate strength to support expected loads.
This is to limit the probability of
failure of ladders when in use, which could lead to harm to persons.
