**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful by inhalation and if swallowed. Irritating to eyes,
respiratory system and skin. Limited evidence of a carcinogenic
effect. May cause sensitization by skin contact.
Potential Health Effects
Eye:
May result in corneal injury. Causes severe eye irritation and
burns.
Skin:
May cause skin sensitization, an allergic reaction, which becomes
evident upon re-exposure to this material. May cause hives. Causes
severe skin irritation and possible burns. Contact with dust causes
drying, cracking, and scaling of the skin.
Ingestion:
Symptoms may include: headache, excitement, fatigue, nausea,
vomiting, stupor, and coma. May cause systemic toxicity with
acidosis. May cause severe digestive tract irritation with abdominal
pain, nausea, vomiting and diarrhea. May be harmful if swallowed.
Inhalation:
May cause severe irritation of the upper respiratory tract with
pain, burns, and inflammation. May cause anosmia (loss of smell).
Inhalation of high concentrations may cause pulmonary edema. Harmful
if inhaled.
Chronic:
Prolonged or repeated eye contact may cause conjunctivitis. Repeated
inhalation may cause chronic bronchitis. Repeated exposure may cause
sensitization dermatitis.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Remove contaminated clothing and shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do NOT use
mouth-to-mouth resuscitation.
Notes to Physician:
Treat exposed person for anion gap acidosis. Treatment for ingestion
includes gastric lavage with water or saline until clear, followed by
activated charcoal with saline or sorbitol catharsis.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Dusts at sufficient concentrations can form
explosive mixtures with air. Combustion generates toxic fumes.
Flammable solid. May re-ignite after fire is extinguished. May burn
rapidly with flare-burning effect.
Extinguishing Media:
For large fires, use water spray, fog or regular foam. For small
fires, use dry chemical, carbon dioxide, sand, earth, water spray or
regular foam. Cool containers with flooding quantities of water
until well after fire is out.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Avoid generating dusty conditions. Remove all sources of
ignition. Provide ventilation. A vapor suppressing foam may be used
to reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Wash hands before eating. Remove
contaminated clothing and wash before reuse. Use only in a
well-ventilated area. Minimize dust generation and accumulation. Do
not get on skin or in eyes. Do not ingest or inhale.
Storage:
Keep away from heat and flame. Keep from contact with oxidizing
materials. Store in a cool, dry, well-ventilated area away from
incompatible substances. Keep containers tightly closed. Keep away
from strong bases.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 30525-89-4:

safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant respirator use.

Carcinogenicity:
Paraformaldehyde -
Not listed by ACGIH, IARC, or NTP.
Other:
See actual entry in RTECS for complete information.
**** SECTION 12 - ECOLOGICAL INFORMATION ****
Ecotoxicity:
Fish: Channel catfish: TLm = 32 ppm; 24 Hr; Fresh water
(Unspecified)Paraformaldehyde hydrolyzes as it dissolves in water,
and its solutions behave like methanol-free formaldehyde solutions.
Formaldehyde forms a strongly acidic aqueous solution, and this
property may cause adverse environmental effects. It is readily
biodegradable and it is not likely to bioconcentrate.
Other
Harmful to aquatic life in very low concentrations.
**** SECTION 13 - DISPOSAL CONSIDERATIONS ****
Products which are considered hazardous for supply are classified as Special
Waste and the disposal of such chemicals is covered by regulations which may
vary according to location. Contact a specialist disposal company or the local
waste regulator for advice. Empty containers must be decontaminated before
returning for recycling.
