If there are no chemical controls which can be implemented at your worksite than one should wear recommended PPE for protection .
- PPE means personal protective equipment .
- PPE at the worksite is selected to reduce the risk to health and safety .
- PPE includes aprons , overalls , gloves , footwear face shields , chemical resistant glasses , and respirators .
- The PPE and administrative control measures depends upon the behavior and supervision of human .
- The efficacy of PPE depends entirely on the workers following the procedures and instructions appropriately .

Answer:
B
Explanation:
When a phospholipid is found in a sphere of water, the hydrophilic head is expected to point towards the water while the hydrophobic tail will point away from the water.
The term hydrophilic means water loving, So it is expected that the hydrophilic head will move towards water molecules at it has affinity for water molecules.
The opposite is the case for the hydrophobic tail. The hydrophobic tail moves away from water molecules
What these cases suggest is that both regions are acting base on their chemical make up. While the hydrophilic head contains molecules which are capable of interacting and bonding with water molecules, the hydrophobic tail contains strictly non polar molecules which are not capable of water interaction. Hence the interactions a phospholipid has with water is through its head region
Answer:
Neon
Explanation:
1s² 2s² 2p⁶ 3s¹ or [Ne] 3s¹
The outer most shell is the 3s¹.
For this atom to achieve stability, if it loses the electron in the 3s shell, it would resemble an inert element with a complete octet configuration. Therefore, the atom would be like:
1s² 2s² 2p⁶ which is the configuration of Ne
