WWC WorkWell Consulting Ergonomic Risk Identification & Assessment Page 1 of 14 TASK ANALYSIS WORKSHEET Company: The Corporation of Delta Department: Engineering Operations Job Title: Flood Box Technicians Date: May 8, 2003 & June 25, 2003 Job Summary: The Flood Box Technicians’ tasks and duties are related to maintenance and construction of municipal utilities, roads, dykes and drainage systems. Primary tasks involve cleaning debris at pump stations and drains, as well as grass-cutting. Secondary tasks include driving from one site to another (25% of the shift). Job tasks are shared between the two crew members (sometimes 3 crew members). A routine and pattern has developed, and the work proceeds efficiently. Tasks that involve manual labour, i.e. major clean-ups (heavy debris such as logs) and cutting grass, are performed on Monday, Wednesday and Friday. Minor clean-ups are performed on Tuesday and Thursday. Personal protective equipment include: safety boots and coveralls. When using weed-eaters, the crew members are required to wear a hardhat, hearing protection and rubber boots (if it’s raining). The Flood Box Technicians’ complained about the use of one type of weed eaters (or string line cutters), i.e. STIHL F5 550 (due to the heavier weight and shorter shaft). From May to September (~3.5 months), the crew members spend about 4 – 5 hours of the shift on weed cutting. N.B : This assessment was based on a working population of males only.
