This document provides safety rules and instructions for a chemistry laboratory. It outlines policies such as wearing protective equipment like goggles and closed-toe shoes. Specific safety tips are given for handling glassware and chemicals, such as adding acid to water slowly and working with volatile chemicals under a fume hood. Procedures for first aid for various injuries from burns to electrical shock are also described. The document aims to ensure safe laboratory practices are followed.

fire blanket, eyewash station, and first aid
kit.

16. Glassware Safety
When pouring liquids into glassware, make sure
the container you are pouring into is resting on a
table at least a hands breadth from the edge.
Pour from large containers to smaller ones.

17. When inserting glass tubing into a rubber
stopper, apply a lubricant to the glass and use

Rapid cooling may make it shatter.
Check glassware for stars or cracks.

18. Always ADD ACID to water
acid
water
“Do not spit into acid!” – a good phrase to
