Exposure Control Methods (Engineering First) questions for the CSP

Question 1

A phlebotomist finishes a draw and removes her gloves. She has no visible contamination on her hands, and she plans to start the next patient's paperwork right away and wash up later at the end of her shift. What does the standard require?

1. AWash hands immediately or as soon as feasible after removing gloves or other PPE
2. BWash hands only if visible blood is seen on the skin after glove removal
3. CWash hands at the end of the shift, provided clean gloves are worn for each patient
4. DUse hand sanitizer once per hour in place of washing, since no skin contact with blood occurred

Question 2

A fabrication shop's air monitoring shows that, even with a well-maintained local exhaust ventilation system and wet-cutting methods in place, employee exposure to respirable crystalline silica remains above the PEL. The employer has confirmed that no additional feasible engineering or work practice controls are available. What does the silica standard require the employer to do?

1. ADiscontinue the engineering controls and rely on respiratory protection alone, since the controls cannot reach the PEL
2. BKeep using the feasible engineering and work practice controls to reach the lowest feasible exposure level and supplement them with compliant respiratory protection
3. CApply only administrative controls, because respirators are permitted only when no engineering controls exist
4. DRotate employees between tasks so that no one is exposed beyond the PEL for a full shift, and stop using the existing controls

Question 3

At the end of a shift, an environmental services worker is handling two pairs of heavy-duty reusable utility gloves that were used to clean blood-contaminated surfaces in a procedure room. Pair 1 is visibly soiled but its rubber is intact, flexible and free of defects. Pair 2 has peeling material across the fingers and palm. Which handling of the gloves complies with the standard?

1. ADecontaminate Pair 1 for reuse and discard Pair 2 because it shows deterioration
2. BDiscard both pairs, because all gloves used with blood must be treated as single-use items
3. CDecontaminate both pairs for reuse, because utility gloves may be reused after decontamination
4. DDecontaminate Pair 2 and reuse it for non-blood tasks, and discard Pair 1 because it is soiled
