a. areas without open doors or windows and poor ventilation.
b. reviewing product labels and instruction sheets for an upcoming job.
c. when the permissible exposure limit is exceeded for a workday.
d. if the safety data sheet lists a requirement for wearing an air - purifying respirator when using a product.

An air - purifying respirator is used to protect against inhaling harmful substances. Areas with poor ventilation (A), exceeding exposure limits (C), and when safety data sheets require (D) are situations that pose inhalation risks. Reviewing product labels and instruction sheets (B) does not involve direct inhalation of harmful substances and thus does not typically require an air - purifying respirator.
