Glass bottles of reactive chemicals that are treated to make them break resistant are stored ___.

• A. in a metal cabinet
• B. in a rubber bucket or sleeves
• C. on a shelf
• D. in a plastic bag

Answer: (B)

Containment and secondary protection are the key ideas here. Even bottles that are treated to be more break-resistant can crack or leak if they’re bumped or dropped, so you want a setup that cushions the bottle and contains any spill. Placing the bottle in a rubber bucket or sleeves provides a padded barrier and a secondary containment layer, so if the glass does fail, the liquid is less likely to spray or spread and shards are less likely to cause injury. Storing on a shelf offers little protection against breakage, a metal cabinet doesn’t provide cushioning for a fall or leak, and a plastic bag can tear and fail to contain a spill. So using a rubber bucket or sleeves best reduces the risk of exposure and cleanup hazards.
