Most noteworthy, the in-appropriate use of timber blocks to chock and/or support equipment whilst undertaking maintenance creates risk. Consequently supporting structures may fail and force equipment to fall onto individuals working around and/or underneath. As a result, serious crush injuries and death can occur. Failed jack, poor quality support stands and various unsafe use practices also attribute to these problematic situations.
- Unsuitable workshop facilities and tooling
- Poor selection and use of equipment that are not fit for purpose
- Lack of appropriate work safe systems i.e. No Safe Work Method Statement/Safe Work Procedure/Risk Assessment etc.
- Failure of individuals and/or organisations to recognise the hazards
- Poor risk assessment and control measures
- Specifically designed, fit for purpose, equipment support stands.
- Relevant State/Country Standards of operation to certify equipment support stands.
- Suitable concrete slab used in workshops to raise and support elevated machinery/loads. Improvisation of repairs on uneven, rough or non-concrete ground in general operating areas creates an unacceptable risk.
The risk assessment process may consider timber blocks in some cases:
- Increase the level of friction between the steel chassis or machinery contact area and the contact head of the support stand.
- Vibrations, possible lateral movement or other accidental contacts with the supported machinery that could shift the load.
- Furthermore to support components that could be damaged by the contact area of the steel stand.
