P/N: 810-316
MATERIAL SAFETY DATA SHEET 02440 Pg. 2
3. Hazard Identification/Potential Health Effects
EYES: Irritation may develop.
SKIN: Irritation may develop.
INHALATION: Irritation may develop.
INGESTION: Not available.
MEDICAL CONDITIONS AGGRAVATED: None known.
CHRONIC OVEREXPOSURE: Exposure to formaldehyde over a long period of time can increase
the risk of cancer to the nose, accessory sinuses, and lungs in humans. Various animal
experiments have shown formaldehyde to be a carcinogen in rats.
ACUTE OVEREXPOSURE: Formaldehyde is irritating to the upper and lower air ways. At
concentrations above 5 ppm coughing, tightness in the chest and wheezing can occur. Upper air
way irritation is most common at levels above 1 ppm; however, irritation has occurred in some
workers with exposures as low as 0.1 ppm. Symptoms of upper airway irritation may include
dry or sore throat, itching or burning sensations of the nose, and nasal congestion. Airborne
concentrations between 0.05 ppm and 0.5 ppm can be irritating to the eyes with burning, itching,
redness and tearing. An increased rate of blinking and eye closure is a natural mechanism that
helps to protect the eye from damage at low levels.
CARCINOGENICITY: Formaldehyde is listed by NTP and IARC as a potential cancer causing
agent.
4. First Aid Measures
EYES: Flush with large amounts of water for 15 minutes minimum and consult a physician.
SKIN: Wash affected area with soap and water, wash clothing before reuse and if irritation persists,
consult a physician.
INHALATION: Remove individual(s) to fresh air and monitor breathing. If breathing difficulties
persist, consult a physician.
INGESTION: Not available.
5. Fire Fighting Measures
FLAMMABLE PROPERTIES: Non-flammable.
Flash Point: None. Method Used: Not applicable.
Flammable Limits (% by Volume in Air):
Lower: None. Upper: None.
AUTO-IGNITION TEMPERATURE: Not applicable.
HAZARDOUS COMBUSTION PRODUCTS: Not available.
EXTINGUISHING MEDIA: Standard fire fighting procedures for any class A (combustible)
material such as water, carbon dioxide, dry chemical, or halon.
FIREFIGHTING INSTRUCTIONS: Use of self-contained breathing apparatus is recommended for
fighting fire in confined area to protect against possible products of decomposition.
6. Accidental Release Measures
P/N: 810-316
MATERIAL SAFETY DATA SHEET 02440 Pg. 3
SMALL/LARGE SPILL: If not contaminated, collect for reuse. If contaminated, dispose of
material according to proper procedures.
7. Handling and Storage
HANDLING: Trapped air between material and outer wrap may contain vapors of formaldehyde.
Open bags in well-ventilated areas. Monitor area for airborne concentrations of formaldehyde.
STORAGE: Store in a cool, well-ventilated location and protect from contamination. It is
recommended that warehouses be sprinkler-equipped for fire protection.
8. Exposure Controls/Personal Protection
ENGINEERING CONTROLS: Local exhaust or general.
RESPIRATORY PROTECTION: If workplace exposures exceed the TWA then refer to 29 CFR
1910.1048 Table 1.
SKIN AND HAND PROTECTION: Gloves if found necessary.
EYE AND FACE PROTECTION: Safety glasses with side shields.
OTHER PROTECTIVE EQUIPMENT: None under normal product use.
