II - To prevent worker injury or exposure to toxic gases.
III - To determine the dew point of the cargo hold.
IV - To prevent an explosion.
It states the standards regarding special training requirements for personnel on certain type of ships.
This term refers to the gaseous phase of a substance that generally exists as a liquid or solid at room temperature.
Which of the four types of gas hazards requires a personal protection type of monitoring for the worker safety?
What regulation states that “When transporting a bulk cargo which is liable to emit a toxic or flammable gas, or can cause oxygen depletion in the cargo space, an appropriate instrument for measuring the concentration of gas or oxygen in the air shall be provided together with detailed instructions for its use”?
What will happen if the space has 21% oxygen and 15%LEL of methane gas?
It is the minimum concentration of a combustible gas in air necessary for burning to occur.
Which of the following statement/s describe/s a gas detector?
I - A device which detects the presence of various gases within an area.
II - Used to detect a gas leak and interface with a control system so a process can be automatically shut down.
III - A device which could sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave the area
III - A device which will evacuate the victim going out of an enclosed space.
This condition inside an enclosed space will happen when chemical reactions, such as rusting or the hardening of paints or coatings occur. The most obvious reason of this condition is the introduction of inert gas into the space.
Which of the following needs to be considered when using tubes or span gases for equipment using the chemical absorption or reaction principles?
From the information given below, which order of operation in using a portable gas meter during measuring mode is correct?
Which portable gas detector is to be carried by a person entering an enclosed space?
