Occupational risk assessment: review of wooden scaffold board application in Malaysian oil and gas industry

Timber scaffold boards have been widely utilised in the offshore construction industry. However, technical specifications and inspection procedure for the application of scaffold boards from a wood material were inadequate. In the development of the standard requirements, evaluation of actual engine...
