On days likely to cause heat stress, activities which cause a high metabolic workload or require working in an enclosed area should be scheduled and performed in the early part of the day. All employees should adjust their work rate to a moderate level. Walking about with moderate lifting and pushing is an example of a moderate level of activity. Fresh water should be readily available in the work vicinity in order that the employees can frequently drink small quantities. It has been demonstrated that areas such as stairwells and hallways can be at a higher heat stress level than outdoor areas.
Air movement provided by fans can significantly lower the level of heat stress.
Every Hour 1. A light workload would be performing light hand or arm work. A moderate workload would be walking about with moderate lifting and pushing.
