you are allowed to enter the chemical preparation/storage area any time you need to get an item.
true
false

Explanation:

• For the first question, in a laboratory, long hair should be tied back or kept out of the way with a hair - band, etc. to prevent accidents (e.g., from getting caught in equipment or coming into contact with chemicals). Holding it with one hand is not practical for long - term work, cutting it short is not necessary, and “neatly groomed” is too vague.
• For the second question, chemical preparation/storage areas often have specific access requirements (e.g., proper training, authorization, and sometimes only during certain times or with supervision). So, you are not allowed to enter any time you need to get an item.

Answer:

• First question: tied back or kept entirely out of the way with a hair band, hairpins, or other confining device
• Second question: False
