What hazard class is formaldehyde?

What hazard class is formaldehyde? Hazard Class: UN 1198 (3, Flammable) UN 2209 (8, Corrosive) Formaldehyde is a FLAMMABLE GAS or COMBUSTIBLE SOLUTION. Use dry chemical, CO2, water spray or alcohol-resistant foam as extinguishing agents.

What hazard class is formaldehyde?

Hazard Class: UN 1198 (3, Flammable) UN 2209 (8, Corrosive) Formaldehyde is a FLAMMABLE GAS or COMBUSTIBLE SOLUTION. Use dry chemical, CO2, water spray or alcohol-resistant foam as extinguishing agents. Use water spray to reduce vapors. POISONOUS GASES ARE PRODUCED IN FIRE.

What class is formaldehyde?

Organic compound
Formaldehyde/Classification

Is formaldehyde a hazmat?

FORMALDEHYDE (ENVIRONMENTALLY HAZARDOUS SUBSTANCES, SOLID, N.O.S.) may react violently with strong oxidizing agents (hydrogen peroxide, performic acid, perchloric acid in the presence of aniline, potassium permanganate, nitromethane). May generate toxic formaldehyde gas when heated.

What is the CAS number for formaldehyde?

50-00-0
Formaldehyde

Names
Systematic IUPAC name Methanal
Other names Methyl aldehyde Methylene glycol (diol forms in aqueous solution) Methylene oxide Formalin (aqueous solution) Formol Carbonyl hydride
Identifiers
CAS Number 50-00-0

What is the pH of formaldehyde?

Like all aldehydes, formaldehyde absorbs oxygen comparatively readily even from the air and is thereby oxidised to formic acid. Solutions of formaldehyde attain fairly rapidly and maintain a pH of 3.5 or even of 3.

Why is it illegal to pour formaldehyde down the drain?

NEVER dispose of formalin down the drain without neutralizing it, and DO NOT pour neutralized formalin down the drain without authorization from the local Publicly Owned Treatment Works (POTW). Formalin contains methyl alcohol, a biocide which could harm the “good” bacteria in the wastewater treatment plant (WWTP).

What is formaldehyde used in?

Formaldehyde is a strong-smelling, colorless gas used in making building materials and many household products. It is used in pressed-wood products, such as particleboard, plywood, and fiberboard; glues and adhesives; permanent-press fabrics; paper product coatings; and certain insulation materials.

What kind of odor does formaldehyde have?

A colorless liquid with a pungent irritating odor. Contains 37-50% formaldehyde by mass and varying amounts of methanol, added to prevent precipitation of formaldehyde polymers (formaldehyde exists in solution as CH2(OH)2 and its polymers HO(CH2O)xH where x averages about three).

What is the formula for formaldehyde in solids?

Solids containing varying amounts of formaldehyde, probably as paraformaldehyde (polymers of formula HO(CH2O)xH where x averages about 30). A hazard to the environment.

What is the NFPA code for hazardous materials?

NFPA 400: Hazardous Materials Code: NFPA 401: Recommended Practice for the Prevention of Fires and Uncontrolled Chemical Reactions Associated with the Handling of Hazardous Waste: NFPA 402: Guide for Aircraft Rescue and Fire-Fighting Operations: NFPA 403: Standard for Aircraft Rescue and Fire-Fighting Services at Airports: NFPA 405

Why is methanol added to a formaldehyde solution?

Normally stable, even under fire conditions. A colorless liquid with a pungent irritating odor. Contains 37-50% formaldehyde by mass and varying amounts of methanol, added to prevent precipitation of formaldehyde polymers (formaldehyde exists in solution as CH2 (OH)2 and its polymers HO (CH2O)xH where x averages about three).
