Haze often originates from regional forest fire, exacerbated during dry spells and carried into Singapore by prevailing winds. 

Businesses may be affected in the following ways:

Employers are encouraged to:

• Take essential precautions outlined in the Guidelines for Employers on Protecting Employees from the Effect of Haze issued by MOM

• Ensure Business Continuity Plan (BCP) is in place and employees are familiar with the process and procedures.  

• Businesses especially those with outdoor operations should maintain at least a 1-week supply of N95 masks
