Perform a job hazard analysis (JHA) to identify chemical exposures for a worker. When complete, you will recommend if air sampling is required or if the hazards can be mitigated by engineering or administrative controls. You must justify your answer. You will receive up to 10 points for each chemical evaluated in the processes below for a total of 30 points. Points will be awarded for thoroughness of information collected and for accuracy in determining the correct need for further sampling or just using controls.
