Overview of ANSI A10.49: A Qualitative Exposure Assessment Approach to Chemical Hazards in Construction and Demolition

Presented: Dec 6, 2022  Available until: Dec 31, 2023

Safety hazards such as falls, slips and trips, and noise get a lot of attention in construction. But far more construction workers die each year from exposure to chemical hazards (such as asbestos, silica, and lead) than from safety hazards. EHS professionals need to be aware of the chemical hazards associated with construction activities. ANSI A10.49, Control of Chemical Health Hazards in Construction and Demolition Operations provides EHS professionals with a qualitative exposure assessment approach to evaluating chemical hazards. During this webinar, we will review the A10 series of standards and evaluate when to perform a quantitative exposure assessment.


Upon completion, participants will be able to:  

  1. Recall ANSI A10 series of standards cover the requirements for Construction and Demolition Operations
  2. Apply a three-step process to performing a qualitative exposure assessment for chemical hazards associated with construction and demolition operations
  3. Describe the role of a Job Health Hazard Analysis (JHHA) in the qualitative exposure assessment approach
  4. List changes in the upcoming 2022 standard
