On October 22, the Commission for Air Quality Management (CAQM) ordered the implementation of Stage 2 emergency measures under the Graded Response Action Plan (GRAP) to curb the city's air pollution.
 
Under this phase of GRAP, additional efforts focus on tackling dust pollution and limiting emissions from diesel generators, a move aimed at curbing further deterioration. Authorities deploy mechanical and vacuum road sweepers, conduct water sprinkling operations on key roads, and intensify inspections at construction sites to enforce strict dust control measures.
