IV FIRE AND EXPLOSION H AZARDS DATA
Flash Point (Method used): N/A Flam mab le Limits: LEL: N/A UEL: N/A
Extingu ishing Media: Dry chemical, Class D extinguisher. DO NOT USE W ATER.
Special Fire Fighting Procedures: Firefighters sh ould wear a N IOS H/M SH A approve d self-c ontained breathing apparatus and full
protective clothing.
Unusual Fire & Explosion Hazard: Product will burn under fire conditions. May react with water liberating flamm able, explosive
hydrogen gas. Like all organic and most dry chemicals, as a powder or dust, this product (when mixed with air in critical proportions
and in the presence of an ignition source) may present an explosion hazard.
V HEALTH HAZARD INFORMATION
Effects of Exposure: Acute:
Inhalation: Low acute inhalation toxicity. May cause upper respiratory tract irritation.
Ingestion: Low acute oral toxicity.
Skin : Skin absorption not likely. Essentially non-irritating.
Eye: Non-irritating. May cause foreign body irritation only.
Medical Conditions Possibly Aggravated by Expo sure: Inhalation of product may aggravate existing chronic respiratory problems
such as asthma , emp hysem a or bro nchitis.
Carcino genicity: NTP: No IARC: No OSHA: No AC GIH : No
EMERG ENCY AND FIRST AID PROCEDURES:
INHALATION: If respiratory irritation or distress occurs remove victim to fresh air. Seek medical attention if respiratory irritation
or distress con tinues.
