| Chemical Properties | Back Directory | [Appearance]
Formaldehyde is a colorless, pungent gas or
aqueous solution. The Odor Threshold is 0.8 ppm. Also,formalin is an aqueous solution that is 37% formaldehyde
by weight; inhibited solutions (added to prevent polymeri zation) usually contain 6 12% methyl alcohol. |

by weight; inhibited solutions (added to prevent polymeri zation) usually contain 6 12% methyl alcohol. | [Potential Exposure]
Formaldehyde has found wide indus trial usage as a fungicide, germicide; and in disinfectants
and embalming fluids. It is also used in the manufacture of
artificial silk and textiles, latex, phenol, urea, thiourea and
melamine resins; dyes, and inks; cellulose esters and other
organic molecules; mirrors, and explosives. It is also used
in the paper, photographic, and furniture industries. It is an
intermediate in drug manufacture and is a pesticide
intermediate. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
30 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, includ ing resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medi cal attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Medical observation is recommended for 24 to 48 hours
after breathing overexposure, as pulmonary edema may be
delayed. As first aid for pulmonary edema, a qualified med ical professional might consider administering a corticoste roid spray. Cigarette smoking may exacerbate pulmonary
injury and should be discouraged for at least 72 hours
following exposure. If symptoms develop or overexposure
is suspected, chest X-ray should be considered. | [Shipping]
UN1198 Formaldehyde solutions, flammable,
Hazard Class: 3; Labels: 3-Flammable liquid, 8-Corrosive
material. Cylinders must be transported in a secure upright
position, in a well-ventilated truck. Protect cylinder and
labels from physical damage. The owner of the compressed
gas cylinder is the only entity allowed by federal law
(49CFR) to transport and refill them. It is a violation of
transportation regulations to refill compressed gas cylinders
without the express written permission of the owner.
UN2209 Formaldehyde solutions, with not<25% formal dehyde, Hazard class: 8; Labels: 8-Corrosive material.
UN3077 For solids containing varying amounts of formal dehyde : UN3077
Environmentally hazardous substances, solid, n.o.s., Hazard
class: 9; Labels: 9-Miscellaneous hazardous material,
Technical Name Required. | [Incompatibilities]
Pure formaldehyde may polymerize
unless properly inhibited (usually with methanol). May
form explosive mixture with air. Incompatible with strong
acids; amines, strong oxidizers; alkaline materials; nitrogen
dioxide; performic acid; phenols, urea. Reaction with
hydrochloric acid forms bis-chloromethyl ether, a carcino gen. Formalin is incompatible with strong oxidizers, alkalis,
acids, phenols, urea, oxides, isocyanates, caustics,
anhydrides. | [Waste Disposal]
Return refillable compressed
gas cylinders to supplier. Incineration in solution of combus tible solvent. Consult with environmental regulatory agen cies for guidance on acceptable disposal practices. Generators
of waste containing this contaminant (≥100 kg/mo)
must conform with EPA regulations governing storage, trans portation, treatment, and waste disposal. | [Definition]
ChEBI: Formaldehyde is an aldehyde resulting from the formal oxidation of methanol. It has a role as a carcinogenic agent, an allergen, an EC 3.5.1.4 (amidase) inhibitor, a disinfectant, an environmental contaminant, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a one-carbon compound and an aldehyde. |
