What is considered hot work?

Definition. “Hot work” means riveting, welding, flame cutting or other fire or spark-producing operation. Hot work in confined spaces. Hot work shall not be performed in a confined space until a designated person has tested the atmosphere and determined that it is not hazardous.

What does OSHA define as hot work?

OSHA defines hot work to include riveting, welding, flame cutting, or similar fire- or spark- producing operations. Requirements for hot work are in 29 CFR 1917.152.

Is using a heat gun considered hot work?

Expanding on OSHA’s definition, hot work means welding, brazing, cutting, soldering, thawing pipes, using heat guns, torch applied roofing and chipping operations, or the use of spark-producing power tools, such as drilling or grinding.

Is cutting concrete hot work?

Hot work is defined as any activity that involves open flames or produces heat and/or sparks capable of initiating fires or explosions. Examples of hot work include: welding, cutting, grinding, drilling, soldering, brazing, torch-applied roofing, etc.

What is hot work with example?

Hot work is a process that involves welding, soldering, brazing, cutting, grinding, drilling and burning or melting metals or other substances such as glass. Use of open flame in the furnace or sparks or such ignition tools are considered hot work procedures.

Is abrasive blasting considered hot work?

Hot work includes welding, cutting, burning, abrasive blasting, and other heat-producing operations. Hot work presents an increased risk of fire and explosion hazards because it is most often performed in confined and enclosed spaces.

Which activities are considered under hot work permit requirements in the chemical industry?

Common hot work processes involve welding, soldering, cutting, brazing burning and the use of powder-actuated tools or similar fire producing operations outside of designated hot work areas. When flammable materials are not present, industrial processes such as grinding and drilling become cold work processes.

Is cutting and grinding considered as hot work?

What must a hot work permit specify?

Hot-work permits are required for any operation involving open flames or producing heat and/or sparks and must be prepared by a competent person. Hot works include brazing, torch cutting, grinding, soldering and welding. Hot work must cease at least one hour before end of shift.

What is hot work and cold work?

The American Petroleum Institute defines hot work as any work that involves welding, burning, or hot tapping or the use of equipment near an open flame or equipment capable of generating a spark. Cold work describes a situation where the task being performed does not generate any sources of ignition.

Is Cold cutting hot work?

Cold cutting is a highly versatile, precise, and safe method of cutting pipe that allows workers to operate the cutting tool from a safe distance. Unlike grinding or torching operations, cold cutting produces no sparks or flames making it inherently safe. A hot work permit is not required in most cases.

How many types of hot work are there?

Is TIG welding considered hot work?

A HWP authorizes hot work operations to be performed outside a designated area established by an Operational Safety Procedure (OSP) including Tungsten Inert Gas/Metal Inert Gas (TIG/MIG) welding.

Does grit blasting require hot work permit?

Grit blasting, de-scaling on deck and in tanks and the use of pneumatic power tools generally present a lower risk, and hence is not within the definition of Hot Work. However when grit blasting in tanks, a hot work approval plan shall be submitted to the office for internal control.

Is drilling classed as hot works?

However, in high-risk environments, where flammable atmospheres are present, the use of low-energy ignition sources may also be categorised as hot work, eg: drilling.

Is grinding cold work?

When flammable materials are not present, industrial processes such as grinding and drilling become cold work processes.

Is cutting metal hot work?

Answer: Yes, metal stud cutting meets the definition of hot work as prescribed in NFPA 51B (see above).

What is the difference between cold work permit and hot work permit?

A hot work permit refers to any situation which arises flames, sparks etc to cause ignition. fire. A cold work permit refers to situations which will NOT lead to ignition at workplace or materials. It will not create a flamable atmosphere.

Which metal working process is not a hot working process?

Cold Working
Explanation: Cold Working: Plastic deformation of metals below the recrystallization temperature is known as cold working. It is generally performed at room temperature.

Is arc welding hot work?

is any work that produces fire or sparks. This includes riveting, flame cutting, soldering, and brazing, but the most common type of hot work is arc welding.
