Is Formaldehyde Flammable? 

This article will answer the question, is Formaldehyde flammable? It also covers several topics about what Formaldehyde is, the types and products of Formaldehyde, the risks of using Formaldehyde for health, also the formaldehyde safe work practices.

Is Formaldehyde Flammable?

Formaldehyde, although it has the potential to burn, it isn’t easy to ignite. When heated, vapors can combine with air to generate combustible combinations, posing an explosion risk indoors, outdoors, and sewers.

What is Formaldehyde?

Formaldehyde is a transparent hazardous gas produced by the oxidation of methanol and utilized in various applications such as in agriculture, food preservation, metallurgical industry, oil and gas manufacture, and laboratory.

Formaldehyde is frequently sold as a 37 percent solution and is soluble in water. 

What are the Types of Formaldehyde?

Here are some types of chemical-based on Formaldehyde:

  • Melamine
  • Urea Formaldehyde
  • Phenol-Formaldehyde
  • Methylene Diphenyl Diisocyanate
  • 1-4 butanediol
  • Polyoxymethylene

What are the Applications of Formaldehyde?

Here are a few examples of formaldehyde applications in various industries:

  • Preservation of fish, certain oils and fats, cleaning of containers, storage of dried goods, and modification of starch for cold swelling
  • Oil well drilling fluid biocide and auxiliary refining agent
  • Grain preservation, seed treatment, rot prevention for feed, nitrate fertilizer in soils, and protection of dietary protein in ruminants are all examples of agricultural practices
  • Carrier for vapor depositing and electroplating procedures; anticorrosive agent in metallurgical manufacturing
  • In textile printing, formaldehyde-releasing agents offer crease resistance, dimensional stability, and flame retardance
  • Latex biocide, adhesive additive, and synthetic rubber anti-oxidizer additive

What are the Risks of Using Formaldehyde to Health?

It is essential to keep the formaldehyde concentration below the 0.3 ppm threshold, which is the authorized limit in formaldehyde-working situations. Formaldehyde has a detrimental and even toxic effect on numerous tissues and organs in the body.

You may experience various symptoms, such as coughing, sore throat, chest pain, and wheezing. If you have a previous history of asthma and bronchitis, you are more likely to experience a relapse when you inhale these compounds.

This chemical can also cause bleeding in the stomach or intestines and damage the liver, spleen, pancreas, and kidneys. In severe cases, this one chemical can also cause coma to death.

Short-term exposure of this chemical can irritate the skin and can cause itching, irritation, and sunburn. Long-term formalin exposure is associated with cancer potential.

How are the Formaldehyde Safe Work Practices?

Working Environment

  • In terms of corridors, and the outside environment, laboratory rooms must be under negative pressure. The room’s doors must be kept shut at all times
  • Use a properly equipment and certified chemical that does not exhaust into the room when working with concentrated more than 4% formaldehyde solutions
  • Do not utilize hoods or cabinets with laminar flow. When choosing a containment device, think about the procedures that will be done
  • Within the immediate work environment, emergency eyewash and a safety shower must be conveniently accessible

Personal Protective Equipment

  • Spills should be cleaned up as soon as possible
  • Preparing specimens for chemical treatment that have been fixed with Formaldehyde at a concentration of 37 percent or greater, either alone or in combination with phenol
  • Put on a lab coat
  • When there is a big chance of contact, wear two pairs of disposable nitrile exam gloves or one pair of non-disposable nitrile or butyl gloves  with minimum ten mil thickness
  • When work is done outside of proper containment, Formaldehyde may be present in the air. Respiratory protection may be needed if ventilation and other control methods are not adequate or practical
  • Replace gloves after each usage or whenever they become ripped, punctured, or soiled
  • Use safety glasses with side shields or wear facial protection, such as a face shield and a chemical mask, if splash/spatter is a risk


Formaldehyde is very rarely to ignite, even though it can burn. Vapors can interact with air to form fire when heated. Other potential risks are associated with using Formaldehyde, such as health issues or irritation when exposed. 

Several precautions must be taken to avoid the harmful effects of formaldehyde use.

Frequently Asked Question (FAQs): Is Fertilizer Flammable?

What is the primary treatment for formaldehyde exposure?

  • If this chemical contact with eyes and skin irrigate quickly with an adequate number of water occasionally elevating the lower and upper eyelids
  • If this chemical gets into your clothes, remove them immediately and cleanse your skin with moisture. If the irritation remains after you’ve washed it, seek medical help
  • If a person breaths excessive amounts of this chemical, relocate them to fresh air as soon as possible. Perform artificial respiration if breathing has stopped. As quickly as possible, get medical help
  • If swallowed, get medical assistance immediately

What is the procedure for formaldehyde waste management?

  • Collect garbage in a secure container that is durable and chemically suitable
  • Formaldehyde-containing chemical waste, specimens or tissue sample must be separated and is classified as hazardous waste
  • All trash cans must be adequately sealed or closed
  • Double plastic any used and infected disposable things that aren’t substantially contaminated. Before throwing it in the garbage, label it as non-hazardous waste
