What safety measures must be remembered when using glassware apparatus?

When using glassware apparatus, always handle glass with care to prevent breakage and potential injuries; use appropriate techniques, such as gripping with a cloth or using gloves if necessary. Ensure that glassware is clean and free from defects before use, as cracks can lead to failure under heat or pressure. Additionally, when heating glassware, avoid sudden temperature changes to prevent thermal shock, and always use appropriate protective equipment, such as safety goggles and gloves, to protect against spills or splashes.
