Final answer:
The first two standing sprays at a funeral should be placed near the casket. It is also important for safety equipment in a laboratory, like fire extinguishers and eyewash stations, to be located in easily accessible areas.
Step-by-step explanation:
In the instance there are multiple standing sprays at a funeral, the first two sprays should be placed near the casket. This is typically done to honor the deceased and is a traditional location for floral displays at funerals. When arranging multiple sprays, it is important to maintain a respectful atmosphere and ensure that the placement does not obstruct the view of the casket or interfere with the proceedings.
Similarly, ensuring safety in a laboratory is crucial. Students should know where specific safety equipment is located, such as the fire extinguisher and the eyewash station. These should be in accessible locations, typically near the entrance of the lab or in clearly marked and unobstructed areas to facilitate quick response in case of an emergency.
