1. choose the best answer.

which of the following is a lab safety rule?
report damaged glassware or equipment.
report accidents at least three days later.
wear sandals whenever you go to the laboratory.
handle chemicals according to instructions from other students.

Explanation:

Lab safety rules are in place to ensure the safety of individuals in a laboratory setting. Reporting damaged glassware or equipment is a crucial safety measure as it helps prevent accidents caused by faulty or broken items. Reporting accidents three days later is not a safety rule; accidents should be reported immediately. Wearing sandals in the laboratory is not safe as they do not provide adequate foot protection. Handling chemicals according to instructions from other students is not reliable; proper instructions should come from authorized sources like lab manuals or instructors.

Answer:

Report damaged glassware or equipment.
