    (a) training employees in PPE use
    (b) providing PPE to every worker
    (c) conducting a hazard assessment
    (d) writing a safety policy

    (b) conduct hazard assessments regularly
    (c) properly wear and maintain PPE
    (d) approve PPE budget requests

    True/False Questions

    13. True/False: Employees are responsible for properly wearing PPE and reporting when it needs repair or replacement.
    14. True/False: Conductive shoes should not be worn in explosive environments to prevent the buildup of static electricity.
    15. True/False: Hearing protection is required at 90 dB if exposure exceeds 8 hours.
    16. True/False: The comfort and proper fit of PPE are important because they encourage employees to use it.
    17. True/False: Employees should never drill holes or paint hard hats, since this may reduce their protective integrity.
    18. True/False: PPE that is too loose, too tight, or uncomfortable often leads to workers not wearing it consistently.
    19. True/False: PPE should be treated as the first line of defense rather than the last resort.
    20. True/False: Safety glasses or a face shield should be worn during any work task that may cause foreign objects to enter the eyes. For example, during welding, cutting, grinding, nailing.
    21. True/False: Hard hats should be routinely inspected for dents, cracks or deterioration, and get replaced after a heavy blow or electrical shock.
    22. True/False: Construction workers are supposed to use earplugs or earmuffs in high-noise work areas where chain saws or heavy equipment are used.
    23. True/False: Personal protective equipment can protect employees from all workplace hazards.
    24. True/False: Employer should provide PPE at no cost to the employee.
