Vietnam General Confederation of Labour
National Institute of Labour Protection
Survey for evaluating
dust-prevention practices
in Vietnamese foundries
This survey supports the National Action Programme on the Prevention of
Silicosis. The purpose of the survey is to (1) review current dust management
practices; (2) identify needed improvements especially low-cost
dust-prevention practices that employers could implement immediately; and (3)
assist the Government of Viet Nam as well as the Viet Nam General Confederation
of Labour in future dust-management planning, for example, establishing new
policies, legislation, and projects to improve working conditions and prevent
silicosis.
Please answer the questions or mark (X) in an appropriate blank square. Thank
you.
