WAC 296-864-30010
Make sure the restraint device meets
these requirements.
You must:
• Make sure the restraining device or barrier can
withstand a rim wheel separation that occurs at one hundred
fifty percent of the maximum tire pressure specified.
• Make sure the restraining devices and barriers will
contain any components that may be thrown out during a wheel
separation of any rim wheel.
• Make sure restraining devices and barriers are visually
inspected:
– Prior to each day's use;
AND
– After any separation of the rim wheel components or
sudden release of air.
• Make sure any restraining device or barrier that shows
damage is immediately removed from service. Examples of
damage include:
– Cracks at welds;
– Cracked or broken components;
– Bent or sprung components caused by mishandling, abuse,
tire explosion or rim wheel separation;
– Pitting of components due to corrosion;
OR
– Other structural damage that would decrease its
effectiveness.
• Make sure restraining devices or barriers removed from
service are not used until they are repaired and reinspected.
• Make sure restraining devices or barriers that need
structural repair are not used until they are certified by
either:
– The manufacturer;
OR
– A registered professional engineer.
Note:
The certification needs to show that the barrier can withstand a force of one hundred fifty percent of the maximum
tire pressure in the event of wheel separation.
