(a)
Interpretation:
Among acetylsalicylic acid, acetic acid, phosphoric acid, and acid anhydride, that are hazardous to breathe dust/vapor/fumes should be explained.
Concept introduction:
Material Safety DataSheet is a document that contains details on the potential health effects of exposure to the chemicals. It also provides guidance for safe procedures to handle chemical products. The hazard evaluations on the use and storage of chemicals and the safety measure taken if accidents occur.
(b)
Interpretation:
Among acetylsalicylic acid, acetic acid, phosphoric acid, and acid anhydride the compounds that are most likely to be inhaled accidentally on the basis of their boiling point should be determined.
Concept introduction:
The temperature at that the vapor pressure of a liquid is equal to the atmospheric pressure is termed as the boiling point of that liquid. Lower the atmospheric pressure above a liquid, the lower is the temperature to boil the liquid. The temperature at that a substance changes state from its solid-state to liquid state is known as its melting point. The solid and liquid phase of a substance exists in equilibrium at the melting point.
(c)
Interpretation:
Among acetylsalicylic acid, acetic acid, phosphoric acid, and acid anhydride, the compounds that are most dangerous to inhale based on the GHS hazard information should be explained.
Concept introduction:
Chemicals used in the laboratories affect our lives. The widespread utilization of chemicals has caused the development of sector-specific regulations. Therefore, readily available information about hazardous properties of chemicals and recommended control measures make the use and disposal of chemicals to be managed safely. Globally Harmonized System of Classification and Labelling of Chemicals
explains and classifies hazards related to a chemical product.
(d)
Interpretation:
Among acetylsalicylic acid, acetic acid, phosphoric acid, and acid anhydride the compounds that are used to be handled in fume hood should be determined.
Concept introduction:
A fume hood is an enclosed device except for the necessary exhaust purposes that are on three sides, top and bottom. It is designed to draw air inward by means of mechanical ventilation and also used to control the exposure to hazardous substances.
