Exposure to excessive noise levels is a serious concern for the long term health of construction workers. Efforts must be made to closely monitor noise levels and adjust working methods accordingly.
See the examples below for how one site addressed this:
- The contractor worked with Pulsar to produce a noise control procedure, developed into a flashing blue siren when 80 decibels is exceeded. This warning is hard to ignore, reminding operatives when hearing protection must be worn.
- Personal noise dosimeters were issued to the workforce. These gadgets attach to a hard hat and record noise throughout a shift, allowing data analysis of the personal noise levels of operatives in different trades.
- The site also registered online with Point of Work Risk Assessments (PoWRA) which allows data gathering into a spreadsheet, real-time monitoring and alerting safety inspectors when changes occur.
- The site team submits its own PoWRA, averaging 500 submissions a week. This data is presented in a live tracking page allowing the team to monitor when changes have to be made to the work process.
This comprehensive approach to noise management encompasses a number of features to provide the site team with a thorough understanding of noise management on site. This data tracking will allow the team to make changes where necessary to secure the safety of the workforce.
