SAFETY IN BOILER OPERATIONS

SAFETY IN BOILER OPERATIONS

Explain everything you know about confined space.

Does the code of practices for confined space apply to steam boilers?
What are the potential hazards of confined space?
What are the atmospheric hazards in confined space?
What are the examples of confined space?
What are the examples of activities by authorized entrant persons in the steam boiler?
What are the minimum and maximum oxygen (O2) requirements in a confined space? Why?
What is the flammable gas commonly found in confined space?

What safety precautions must be taken before allowing a man to enter the boiler for repairs? 

What are the precautions to observe when testing a gage glass?
What are the safety precautions during boiler operation?
What are the safety precautions during boiler overhauls or repairs?
What safety precautions must be taken before and after entering the boiler for repairs or cleaning?
When stationing a man outside for safety how long should he stay there?
What is PPE?
Can PPE prevent accident?
What are types of PPE and state their applications
What are the guidelines to follow before preparing chemicals for boiler water treatment?
Suppose the glass of water gage should break discharging water and steam into the room, what would you do?

Should you attempt to raise the safety valve in order to diminish the steam pressure?  NEW 2ND EDITION  
What would you do if the safety valve will not seat?
You walk into the boiler room and observe that there is no water in the gauge glass. What is your next action?
What is your action for a low water level emergency?
The boiler drum pressure gage reading is beyond the MWAP. What do you do?
You hear the boiler vibrating? What do you do?
What is your emergency response plan if you notice low water due to tube failure?
In case of tube failure results in loss of water so great that the water level cannot be maintained with the feed water supply, the procedures are:
What can cause high water in boiler?
What can cause low water in boiler?
What can cause boiler high pressure?
If the boiler feed water pump is operating and the water level in the boiler is not rising, what is the best thing to do? Can you increase the speed of the feed water pump for more water volume?
If a boiler was very low on water and showed signs of overheating, should you fill it with water to cool it down?
You observe steam leaking from the flange of the main stop valve.  What is your next action?
You observe the gage glass is full of water (water line is no longer visible), what is the high water level emergency?
