3.5.4. Site-fabricated ladders:

(1)  Any site-fabricated ladder shall have:

(a)  a maximum length of 4.8 m, measured along the side rails;

(b)  a maximum spacing of 400 mm between the side rails, unless the site where the ladder is used precludes this. In such a case, the width of the ladder may be reduced accordingly;

(c)  a maximum spacing of 300 mm between the cleats. Such spacing shall be uniform within a flight.

(2)  Any wooden ladder must have:

(a)  2 side rails of at least:

i.  38 mm × 89 mm for single ladders; or

ii.  38 mm × 140 mm or 89 mm × 89 mm for double-width ladders;

(b)  cleats:

i.  of not less than 38 mm × 89 mm; and

ii.  resting on filler blocks of not less than 38 mm × 38 mm.

(3)  Any double-width ladder shall:

(a)  have 3 rails evenly spaced;

(b)  be at least 1.5 m in width and not more than 2 m in width;

(c)  have cleats in one piece that extend the full width of the ladder;

(d)  be made of materials whose size is corresponding to those listed in subsections 1 and 2; and

(e)  be solidly fastened in place.

(4)  The wood used for a ladder shall fulfil the following conditions:

(a)  it shall be in good condition, shall be derived from species having long non-breaking fibres and shall be free from any defect that might impair its strength;

(b)  it shall be of a quality equal to No. 1 spruce;

(c)  if it is in the form of logs, it shall be debarked;

(d)  it shall not be covered with paint or any opaque coating.

(5)  Where it is foreseen that a site-fabricated ladder will exceed the permitted maximum length of 4.8 m, the ladder must be designed by an engineer, as attested to by a plan or certificate signed and sealed by the engineer.

3.5.4. Site-fabricated ladders:

(1)  Any site-fabricated ladder shall have:

(a)  a maximum length of 9 m, measured along the side rails;

(b)  a maximum spacing of 300 mm between the side rails;

(c)  a maximum spacing of 300 mm between the rungs. Such spacing shall be uniform within a flight.

(2)  Any ladder with wooden rungs shall have:

(a)  side rails of at least:

i.  40 mm × 90 mm for ladders 5.8 m or less; or

ii.  40 mm × 140 mm for ladders over 5.8 m;

(b)  cleats or rungs:

i.  not less than 15 mm × 65 mm; and

ii.  resting on filler blocks.

(3)  Any double-width ladder shall:

(a)  have 3 rails evenly spaced;

(b)  be at least 1.5 m in width;

(c)  have cleats or rungs in one piece that extend the full width of the ladder;

(d)  be made of materials whose size is appropriate to the weight applied; and

(e)  be solidly fastened in place.

(4)  The wood used for a ladder shall fulfil the following conditions:

(a)  it shall be in good condition, shall be derived from species having long non-breaking fibres and shall be free from any defect that might impair its strength;

(b)  it shall be of a quality equal to No. 1 spruce;

(c)  if it is in the form of logs, it shall be debarked;

(d)  it shall not be covered with paint or any opaque coating.
