Special Hazards Control: Hot work

  1. How is hot work defined by OSHA?

Hot work is any work or undertaking that may be the source off an ignition and includes welding, brazing, or any heat and/or open flames that may create a fire hazard regardless of any flammable material.

  1. Why do you think that one would need to test for flammable gases before starting any hot work?

Test for flammables should be done on a continuous basis in order to eliminate potential flammable sources and to determine that the area is free from any hazard.

  1. What is the OSHA standard for Hot Work?

These standards specify precautions that ought to be taken before, during and after hot work to prevent any hazard because of fire or explosion.

  1. Regarding the cylinders used during hot work, what are the potential hazards and how should they be stored.

Dangers of Hot Work, according to the Chemical Safety Board include the fact that cylinders are prone to explosions and bursting which may lead to damages.


  1. What are the Seven Key Lessons from the US Chemical Safety Board?

The seven key lessons include

  1. There should be use of alternatives wherever possible in order to avoid hot work
  2. The analysis of the hazard should be done before the process is started so as to identify the hot work, potential hazards as well as the mitigation measures
  • The hot work environment should be monitored to avoid any anticipation
  1. The hot work area should also be tested for any inflammable source
  2. Only qualified personnel should be allowed to authorize hot work permits and issues
  3. Proper and thorough training on hot works should be carried out to avoid hazards
  • Safety precautions should be provided for external contractors and the necessary information should be availed that include the presence of any flammable materials present
  1. Select two of the incidents on the final report and SUMMARIZE what the hazards were (chemicals), what was not done to prevent the accident, what should have been done to prevent the accident. Hot Work Permit

On October 19, 2008, the explosion that killed contract workers was because of failure to test for gases thereby leading to the interconnected storage tanks to emit vapor leading to explosion. Hot work permit was not issued and there was no briefing of the contractor thereby leading to lack of information. The second case refers to the Bethune point waste water plant, found at, where two workers were killed and one critically injured when a methanol tank exploded. This was because of failure to test the environment, failure to use written permits and the supervision of external contractors. If the environment was well scanned, such would not have happened. All in all, in both cases, the use of alternative should have been a better option, the hazard should have been analyzed including monitoring the environment as well as training the employees thoroughly could have avoided all these chemical hazards.

  1. What is the minimum “fire safe area” recommended for hot work?

The minimum fire safe area is that reserved and planned location that is designed to carry out tasks related to hot work and has the construction materials being noncombustible and equipped with fire extinguishing materials, detectors and alarm systems.

  1. If you cannot meet the minimum “fire safe area” then what should you do?

In certain situations, temporary hot worksites are used to carry out the hot work. In such a situation, the local authority must be contacted for authority before any work commences. Hot work permit should also be sourced so that control plans for the mitigation of fire matters are addressed.

  1. What does the Hot Work Permit do?

The hot work permit ensures that the program being undertaken or the person undertaking the hot works are being done within the specified area. It also indicates that the person holding the permit has fulfilled all the required procedures in conducting hot works.

  1. Examining the Hot Work Permit that UNH uses, for how long is the fire watch provided?

According to UNH, the fire watch must remain in the area during the hot work and for sixty minutes after the work has been concluded.

  1. How long AFTER the hot work should the area be monitored by the fire watch?

The firewatcher has to remain for around three hours after hot work has been completed or until such a time as designated so that he/she may be able to observe all portions. He is also able to control and extinguish any fire that may arise from unnoticed spark that in an unnoticed location that takes a while before the spark develops into a visible fire after the workers have left.

  1. What type of equipment should the fire watch have on hand?

Among the things that a fire watch ought to have on hand includes a fire extinguishing to put of any fire that may have been left after hot work produced sparks in another location or within the work area. At the same time, the fire watch should have a charged small horse and be trained to watch the place and the adjacent places for any hazard.
