STORAGE AND HANDLING RECOMMENDATIONS
Proper storage and handling will help protect your planks from damage that may reduce their useful life. To help ensure optimal
performance and the longevity of your planks, please carefully read the following handling and visual inspection instructions. Scaffold
planks that have been improperly stored or damaged should be removed from service immediately. Failure to remove improperly stored
or damaged planks from service may result in injury or death.
RECOMMENDED STORAGE METHODS
PROTECT FROM
EXTREME CONDITIONS.
• KEEP SCAFFOLD PLANKS DRY. The strength and performance of a scaffold plank is reduced
by increased moisture content.
• Store planks in a dry, well-ventilated area. Storing in wet or unventilated areas will accelerate
wood decay and plank deterioration. Always allow wet planks to dry quickly by providing proper
air circulation.
• Protect planks from extreme weather conditions, including excessive exposure to water and
temperatures exceeding 150 degrees Fahrenheit. Store planks under roof or under a porous cover
Fig. 1
DO NOT
MISALIGN STICKERS.
that will shed water while allowing moisture to escape. (Fig. 1)
• Keep planks stacked in bundles off the ground and supported by stickers spaced no more than
8' apart between each layer. Be sure to line up the stickers between bundles with the ground
stickers. This will allow for easy forklift access and provide air circulation. Misalignment of the
stickers can damage the planks by creating a bow. (Fig. 2)
• Do not store heavy objects on the planks.
RECOMMENDED HANDLING METHODS
Fig. 2
DO NOT
OVERLOAD PLANKS.
• Do not overload the planks; refer to the span charts for loading capacity. Immediately remove
planks that have been overloaded from service and visually inspect prior to reusing. (Fig. 3)
• Throwing planks from scaffolding may cause damage. A thrown plank should be inspected
and evaluated before reuse. (Fig. 4)
• Do not push or hit bundles of scaffold planks with the fork ends. Stickers should be of thick
enough material to allow forklift handling without causing damage to the planks. (Fig. 5)

VISUAL INSPECTION AND EVALUATION
LP LVL H42 Scaffold Planks should be thoroughly visually inspected by a qualified person* prior to each use. Visual inspection along
with proper handling and storage are the best means of assuring safe performance of laminated scaffold planks.
Immediately remove damaged scaffold planks from service. Failure to remove planks from service may result in injury or death.
The following pictures detail the most common examples of damage that affect the structural strength of scaffold planks.
RECOGNIZING VISUAL DEFECTS
End Splits - A separation that extends through the plank from face to face. End splits are
Fig. 6
caused by repeated exposure to wet/dry conditions. If an end split exceeds 18," remove the plank
from service. (Fig. 6)
Saw Cuts, Drilled Holes and Notches - Saw cuts across the face or through the edge of the plank, drilled
Fig. 7
holes or notches will reduce the plank’s load carrying capacity. Planks with saw cuts, drilled holes or notches
should be removed from service and inspected by a qualified person*. (Fig. 7)
Edge Splits - A separation of the narrow edge of the plank usually caused by forklift damage.
A diagonal split may be caused by overloading. Probe the split to determine the depth; shallow
Fig. 8
weather checks are acceptable. If an open split is detected, remove the plank from service. (Fig. 8)
Dents, Gouges and Depressions - Dents can indicate internal structural damage. Dropping the plank or
impact from heavy objects on the plank will dent the plank. Remove the plank from service and visually
Fig. 9
inspect the plank before reuse. (Fig. 9)
Face Breaks - Irregular cracks across the face of the scaffold plank. Usually a result of overloading,
face cracks dramatically reduce the strength of the plank. Remove planks with face breaks
from service. (Fig. 10)
Fig. 10
There are other visible signs of damaged planks. These include DISCOLORATION possibly caused by exposure to chemicals, high temperature or decay.
ODOR may also indicate chemical deterioration. SOFT SPONGY WOOD can be caused by chemical exposure or decay. Planks with discoloration, odor or
soft spongy wood should be removed from service to determine the cause of the problem and the effect it will have on the load capacity of the plank.
*QUALIFIED PERSON, as defined in OSHA Safety and Health Standards and by the SIA, means one who, by possession of a recognized degree,
certificate or professional standing or by extensive knowledge, training and experience, has successfully demonstrated the ability to solve or resolve
problems relating to the subject matter, the work or the project.
