I wasn't able to find specific documentation on the recommended service life and disposal procedure for rubber gloves used as personal protective equipment (PPE) in our current safety knowledge base, but here are industry-standard safety guidelines:

Always inspect gloves prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with the product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.
