2.31 ft/psig

1.98 psig would equalize feet of head 4’7”

4.583/2.31 = 1.98. .583 is 7”/12”


So round off to 2.0 psig to get steady stream of bubbles

Answer:

ACCIDENT PREVENTION RECOMMENDATIONS  

Fatal Fact made us to understand some of the prevention techniques as stated below.

1. Use approved ground fault circuit interrupters or an assured equipment grounding conductor program to protect employees on construction sites.  

2. Use equipment that provides a permanent and continuous path from circuits, equipment, structures, conduit or enclosures to ground.

3. Inspect electrical tools and equipment daily and remove damaged or defective equipment from use until it is repaired.

Explanation:

In order to gain a better understanding of the answer above let explain some terms

Ground Fault Circuit Interrupters :

    A ground fault circuit interrupter (GFCI), or Residual Current Device (RCD) is a type of circuit breaker which shuts off electric power when it senses an imbalance between the outgoing and incoming current. The main purpose is to protect people from an electric shock caused when some of the current travels through a person's body due to an electrical fault such as a short circuit, insulation failure, or equipment malfunction.

So the first statement is implying that in order to prevent this accident that  this device (GFCI) should have  been used in that  construction site, or as  an alternative before the  construction commenced  the company should have drafted a lay down conductor program(i.e. a step by step conductor program) that assured equipment grounding  in order to protect employees on construction sites
