What is the guideline for replacing lab coats and gloves during a procedure?

• A. Reuse after cleaning
• B. Replace only when advised
• C. Launder but never replace gloves
• D. Replace if contaminated or torn or permeated; launder or replace lab coat as needed

Answer: (D)

In lab safety, keeping a strong barrier between you and hazardous materials is key. Gloves must be replaced as soon as they’re compromised: if they’re contaminated, torn, or the material shows signs of permeation, you should switch to a clean pair right away. That’s because a puncture or a permeation pathway can allow chemicals or biological agents to reach your skin, undermining protection. Lab coats have a similar protection goal but different handling. They can be laundered between experiments if they’re not heavily contaminated. If contamination is significant, or if there’s any chance material has penetrated the fabric, or the coat is damaged, it should be replaced. In other words, launder as needed, but don’t assume a coat is still safe after heavy exposure—replace when contamination or damage is present. This approach avoids reusing compromised PPE and recognizes that different items may require different remedies. Reusing gloves after cleaning isn’t reliable because some hazards can penetrate or linger; replacing only when advised is too lax for ongoing protection; and gloves aren’t always salvageable through laundering.
