Hard hat…check Eye protection…check Safety gloves…check Protective footwear…check Respiratory protection: . . . uh oh . . . Although he has almost everything he needs to operate that jackhammer safely, this worker is missing one important piece of PPE: respiratory protection to keep him from breathing in the dust he’s kicking up.
