Concept explainers
(a)
Interpretation:
Calculate the number of cans required to apply paint on the tunnel.
Concept introduction:
It is given that a spray can holds nine fluid ounces and has the capability to cover an area of approximately 25 ft2.
The tunnel is 8 feet wide, 12 feet high and 148 feet long.
Assume the tunnel is rectangular.
(b)
Interpretation:
List top three hazards that might encounter during the project and suggest safety precaution for each hazard.
Concept introduction:
It is given that a spray can holds nine fluid ounces and has the capability to cover an area of approximately 25 ft2.
The tunnel is 8 feet wide, 12 feet high and 148 feet long.
Assume the tunnel is rectangular.
Material Safety Data Sheet (MSDS) is a s a document that contains information on the potential hazards (health, fire, reactivity and environmental) and how to work safely with the chemical product. Therefore, MSDS can be used to answer this question.
