IV FIRE AND EXPLOSION H AZARDS DATA
Flash Point (Method): Not flammable, but may be subject to slow oxidation if stored at temperatures above 140 oF.
Extingu ishing Media: Not flamm able. Use appropriate extinguishing m edia for the comb ustible material involved in the fire. If
oxidation should occur, heat will be liberated which could cause surrounding combustibles to burn. If oxidation starts, the pallet
should b e bro ken apart and cooled w ith water to d issipate th e hea t.
Special Firefighting Procedures: Firefighters should wear self-contained breathing apparatus with full protective clothing to prevent
contact with skin and eyes. Fumes from fire are hazardous. Isolate runoff to prevent environmental pollution.
Unusual Fire & Explosion Hazards: Storage at temperatures above 140 oF may cause the black iron oxide to oxidize, generating
heat which could cause surrounding combustibles to burn. Mixtures with aluminum + calcium silicide + sodium nitrate may explode
if ignited . Mix tures w ith alum inum + sulfur rea ct violently if h eated . Ignites on c ontact with hyd rogen trisu lfide.
V HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of o ur know ledge, the chem ical, ph ysical and toxicolog ical pro perties of iron ox ide have not b een thoro ugh ly
investigated and recorded.
Iron compounds have varying toxicity. Exposure to iron oxides is potentially a serious risk in all industrial settings. Some
iron compounds are suspected carcinogens. In general, ferrous compounds are more toxic than ferric compounds. (Sax, Dangerous
Properties of Industrial Materials, eighth edition)
Routes of Entry: Inhalation, Skin, Eyes
Acute E ffects:
Inhalation: May cause irritation of the upper respiratory tract and possibly acute iron poisoning.
Ingestion: No acute health effects recorded.
Skin : No acute health effects recorded.
Eye: May cause irritation.
Chro nic Effects:
Inhalation: May cause chronic iron poisoning.
Ingestion: No chronic health effects recorded.
Skin : Repeated or prolonged contact may cause irritation.
Eye: No chronic health effects recorded.
Target Organs: May affect the blood.
Carcino genicity: This product is not considered a carcinogen by IARC, NTP, ACGIH or OSHA.
Medical Conditions Generally Aggravated By Exposure: Pre-existing resp iratory disord ers.
EMERG ENCY AND FIRST AID PROCEDURES:
INHALATION: Remove to fresh air, keep warm and quiet give oxygen if breathing is difficult. Seek medical attention if necessary.
INGESTION: If conscious, give 1-2 glasses of mild or water and induce vomiting. Get medical attention. Never induce vomiting or
give anything by mouth to an unconscious person.
SK IN: Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water. Seek medical attention
if sym ptom s persist.
EYE: Flush with copious amounts of water for at least 15 minutes lifting upper and lower eyelids. Call a physician if irritation
persists.
VI REACTIVITY DATA
Cond itions Contributing to Instability: Material is not stable if stored at temperatures above 140 oF.
Chem ical Incompatibilities: It is incom patible with strong oxidizing a gents.
Co nditio ns to Av oid: Storage above 140 oF.
Haz ardous D ecomposition Produc ts: None
Hazardous Polymerization: May occur.
VII SPILL OR LEAK PROC EDURES
Steps to Be Taken in Case Material Is Released or Spilled: We ar appropriate respira tory and protective equipm ent specified in
section VIII Special Protection Information. Isolate spill area and provide ventilation. Vacuum up spill using a high efficiency
particulate absolute (HEPA ) air filter and place in a closed co ntainer for p roper d isposal. Tak e care no t to raise dust. Vacuum or use
wet clean-up techniqu es and place waste m aterial in closed container.
Waste Disposal Method: Disposal must be m ade in accordance with Federal, State and Local regulations. Pursuant to 40 CFR part
261 of the Resource Conservation & Recovery Act (RCRA). Regulations currently in effect, discarded Iron Oxide would not be
classified as a hazardous waste.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection: Use of NIOSH approved dust respirator is recommended when exposure limits may be exceeded.
Ventilation: Local ex haust ve ntilation to collector o r containm ent recom mended to contro l dust to below expo sure limits.
Eye Protection: Wear safety glasses or goggles to protect against du st particles.
Gloves: Leather o r rubber glove s.

Safety Stations: An eye wash station should be available to the area of use.
IX SPECIAL PRECAUTIONS
Hazard Label Information: Store in cool, dry area. Store in a tightly sealed container. Wash thoroughly after handling.
Precautions to Be Taken in Handling and Storing: Do not store at temperatures above 140 oF. Small amounts of Fe 3O 4 may
oxidize and ignite container.
Wo rk Practices: Imp lem ent en gineering and wo rk practice controls to re duc e and ma intain c onc entration o f exp osure at low levels.
Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating and
smok ing. Do not blow dust off clothing or skin with comp ressed air.
Other: In accordance with good industrial hygiene practice, avoid contact with skin, eyes, or clothing. Avoid breathing dust. Keep
away from food products. Keep container closed when not in use. Use with adequate, localized ventilation. Wash throughly after
hand ling and before eating, drink ing or u sing toba cco products.
DO T C lass: Not regulated.
There are extrem ely sm all, but d etectab le am oun ts of substan ces regulated unde r Califo rnia鈥檚 Safe Drin king Water an d Toxic
Enforcem ent Act (Proposition 65):
Arsenic: < 3 ppm Beryllium: < 2 ppm Cadmium: 2-6 ppm Chromium VI: < 0.1 ppm Lead: < 10 ppm
These levels are 鈥渢ypical鈥? quantities and may change slightly with different lots. The term 鈥渓ess than鈥? indicates that the substance was
detec ted, but the am oun t was less than the quan tifiable lim it.
Some of the chemicals listed herein are research or experimental substances which may be toxic, as defined by various
governmental regulations. In accordance with Environmental Protection Agency regulations and the Toxic Substance Control Act
(TS CA ), these ma terials should only be hand led by or und er the direct supervision of a 鈥渢echn ically q ualified indiv idual鈥? as de fined in
40 CFR 710.2(a).
The above information is accurate to the best of our knowledge. However, since data, safety standards and government
